How do I autosubmit the selection made with Twitter Bootstrap typeahead()??
http://twitter.github.com/bootstrap/javascript.html#typeahead
There is a clean way using the updater callback:
input.typeahead({
'source' : ['foo', 'bar'],
'updater' : function(item) {
this.$element[0].value = item;
this.$element[0].form.submit();
return item;
}
});
When user selects an option (either by mouse click or keyboard), the callback populates the input box and sends the form.
If you use the external typeahead.js plugin (recommended for Bootstrap 3):
To trigger a form on select just use the custom events.
$('#my-input')
.typeahead({/* put you options here */})
.on('typeahead:selected', function(e){
e.target.form.submit();
});
More info on custom events here and demo about JSfiddle.
Might not be the best solution, but I just tried this on my typeahead setup locally and it worked.
If your typeahead looks something like this...
<form id="test-form" method="post" action="">
<input id="test-input" type="text" data-provide="typeahead"
data-source='["1","2',"3"]' />
</form>
Then you can submit it with this javascript.
<script type="text/javascript">
$('#test-input').change(function() {
$('#test-form').submit();
});
</script>
Apparently there are a few git merge requests. This one does the job and allows you to send an array of objects to typeahead: https://github.com/twitter/bootstrap/pull/1751
I added a blur callback on the input. Be aware that you need to wait for a short period, that typeahead can change the value in the input and the blur callback is not called before that. It's just a workaround, but it works.
$('input.myTypeaheadInput').blur(function(e) {
window.setTimeout(function() {
window.console && console.log('Works with clicking on li item and navigating with the keyboard. Yay!');
}, 50);
});
To populate a value of a hidden field in an html form from the typeahead data selection, I did the following:
$('#prefetch').typeahead({
hint: true,
highlight: true,
minLength: 1
},
{
name: 'trees',
source: trees,
limit: 15
}).on('typeahead:selected', function(e) {
var result = $('#prefetch').val()
$('#formpane input[name=\"myID\"]').val(result)
});
For reference, here's the html code:
<body>
<div id="formpane">
<form action="/thanks" method="POST">
<input class="typeahead" type="text" placeholder="select categories" id="prefetch">
<button type="submit">Submit</button>
<input type="hidden" name="myID" />
</form>
</div>
<script type="text/javascript" src="js_file_above.js"></script>
</body>

I'm trying to implement the new invisible recaptcha, from Google.
It's all working perfectly, but my forms always have two submit buttons, that does different things with the input.
I tried to simply add another in my form, but google only recognize the first one in code.
I can't think of any reason that would prevent the other button to work properly. Here is a simple example of what I tried :
<form action="page.php" method="POST">
<input type="text" value="textfield"/><br/>
<button class="g-recaptcha" data-sitekey="mysitekey" data-callback='onSubmit' value="anaction">An action</button>
<button class="g-recaptcha" data-sitekey="mysitekey" data-callback='onSubmit' value="anotheraction">Another action</button>
</form>
I usually tell apart the two buttons by making an isset on the POST values. Here it doesn't seem to work with the second button. If I switch the two lines, it will make the other button submit properly.
If someone has an idea about this, I'll thank him for enlightments.
Thank you :)
I had same issue and I fixed it like below:
<button type="submit" class="g-recaptcha"
id="captcha1"
data-sitekey="YOUR_SECRETKEY"
data-callback="sendData">button</button>
<button type="submit" class="g-recaptcha"
id="captcha2"
data-sitekey="YOUR_SECRETKEY"
data-callback="sendData">button</button>
<script type="text/javascript">
$( document ).ready(function() {
$(".g-recaptcha").each(function() {
var object = $(this);
grecaptcha.render(object.attr("id"), {
"sitekey" : "YOUR_SITEKEY",
"callback" : function(token) {
object.parents('form').find(".g-recaptcha-response").val(token);
object.parents('form').submit();
}
});
});
}
);
</script>
Yes I created a function sendData like below:
<script type="text/javascript">
function sendData(){
var test = $("#test").val();
if(test != ""){
$.post( "page.php",
{ 'g-recaptcha-response': grecaptcha.getResponse(), 'test' : test})
.done(function( data ) {
console.log(data);
}
);
}else{
console.log(data);
}
grecaptcha.reset(); //important
}
</script>
Stash the token in a hidden field and use it instead of the g-recaptcha-response value to send your verification request. You can distinguish between the two submissions by saving the action item in the JSON return object. I have no idea why this works, by the way.
<head>
...
<script src="https://www.google.com/recaptcha/api.js"></script>
<script>
function onSubmit(token) {
document.getElementById("token").value = token;
document.getElementById("form").submit();
}
</script>
...
</head>
<body>
...
<form id="form" action="page.php" method="POST">
<input type="hidden" id="token" name="token">
...
<button type="submit" class="g-recaptcha" data-sitekey="..." data-callback="onSubmit" data-action="action">An Action</button>
<button type="submit" class="g-recaptcha" data-sitekey="..." data-callback="onSubmit" data-action="anotheraction">Another Action</button>
</form>
I am pretty much a backbonejs newbie. I am submitting form data to mysql.
I have one special input box where the use types in his or her email address as a user name.
As it stands, I can check all my input fields (user, pass, address, phone, etc) client
side, use an event on a button, load the model, use PHP to put the data into the db.
This works just fine and is tested. The backend validation works fine and feeds to
the browser when necessary.
Now I want to check the loginname field against the back end BEFORE writing the record (I know I can trap this on the back end in the final submit but want to do it here). If the user already has an account with the same email address I want to catch that client side. The issue is I can't seem to find a way to capture this blur (or onblur or change whatever I use) when I move off the loginname field so I can (in the render of the view is all I can figure) go off, use PHP again and send back a flag "new" or "existing"

.live is not needed here, there is nothing wrong with your event hash as well. There could be some thing wrong with template. I did just isolate the input field and focusout event in this jsfiddle it's working fine.
<script type="text/template" id="formtemplate">
<form>
<input type="text" class="loginname" value="" placeholder="enter login"/>
</form>
</script>
...
var View = Backbone.View.extend({
events:{
'focusout .loginname':'checkUser'
},
render:function(){
this.$el.html($('#formtemplate').html());
},
checkUser:function(e){
alert('checkUser'); //works well
}
});
var view = new View();
view.render();
view.$el.appendTo('body');
Okay - you said to tie this to blur, and this format finally worked!
'blur input#loginname' : 'userCheck'
events: {
'click .btn-primary' : 'saveClient',
'blur input#loginname' : 'userCheck'
},
userCheck: function(e) {
console.log("usercheck detected");
alert("Alerts suck.");
},
The console is not showing up, but at least I'm trapping the blur now! Thanks eveyone.
I'm using this method: http://plnkr.co/edit/A6gvyoXbBd2kfToPmiiA?p=preview to only validate fields on blur. This works fine, but I would also like to validate them (and thus show the errors for those fields if any) when the user clicks the 'submit' button (not a real submit but a data-ng-click call to a function)
Is there some way to trigger validation on all the fields again when clicking that button?
What worked for me was using the $setSubmitted function, which first shows up in the angular docs in version 1.3.20.
In the click event where I wanted to trigger the validation, I did the following:
vm.triggerSubmit = function() {
vm.homeForm.$setSubmitted();
...
}
That was all it took for me. According to the docs it "Sets the form to its submitted state." It's mentioned here.
I know, it's a tad bit too late to answer, but all you need to do is, force all forms dirty. Take a look at the following snippet:
angular.forEach($scope.myForm.$error.required, function(field) {
field.$setDirty();
});
and then you can check if your form is valid using:
if($scope.myForm.$valid) {
//Do something
}
and finally, I guess, you would want to change your route if everything looks good:
$location.path('/somePath');
Edit: form won't register itself on the scope until submit event is trigger. Just use ng-submit directive to call a function, and wrap the above in that function, and it should work.
In case someone comes back to this later... None of the above worked for me. So I dug down into the guts of angular form validation and found the function they call to execute validators on a given field. This property is conveniently called $validate.
If you have a named form myForm, you can programmatically call myForm.my_field.$validate() to execute field validation. For example:
<div ng-form name="myForm">
<input required name="my_field" type="text" ng-blur="myForm.my_field.$validate()">
</div>
Note that calling $validate has implications for your model. From the angular docs for ngModelCtrl.$validate:
Runs each of the registered validators (first synchronous validators and then asynchronous validators). If the validity changes to invalid, the model will be set to undefined, unless ngModelOptions.allowInvalid is true. If the validity changes to valid, it will set the model to the last available valid $modelValue, i.e. either the last parsed value or the last value set from the scope.
So if you're planning on doing something with the invalid model value (like popping a message telling them so), then you need to make sure allowInvalid is set to true for your model.
You can use Angular-Validator to do what you want. It's stupid simple to use.
It will:
Only validate the fields on $dirty or on submit
Prevent the form from being submitted if it is invalid
Show custom error message after the field is $dirty or the form is submitted
See the demo
Example
<form angular-validator
angular-validator-submit="myFunction(myBeautifulForm)"
name="myBeautifulForm">
<!-- form fields here -->
<button type="submit">Submit</button>
</form>
If the field does not pass the validator then the user will not be able to submit the form.
Check out angular-validator use cases and examples for more information.

Well, the angular way would be to let it handle validation, - since it does at every model change - and only show the result to the user, when you want.
In this case you decide when to show the errors, you just have to set a flag:
http://plnkr.co/edit/0NNCpQKhbLTYMZaxMQ9l?p=preview
As far as I know there is a issue filed to angular to let us have more advanced form control. Since it is not solved i would use this instead of reinventing all the existing validation methods.
edit: But if you insist on your way, here is your modified fiddle with validation before submit. http://plnkr.co/edit/Xfr7X6JXPhY9lFL3hnOw?p=preview
The controller broadcast an event when the button is clicked, and the directive does the validation magic.
One approach is to force all attributes to be dirty. You can do that in each controller, but it gets very messy. It would be better to have a general solution.
The easiest way I could think of was to use a directive
it will handle the form submit attribute
it iterates through all form fields and marks pristine fields dirty
it checks if the form is valid before calling the submit function
Here is the directive
myModule.directive('submit', function() {
return {
restrict: 'A',
link: function(scope, formElement, attrs) {
var form;
form = scope[attrs.name];
return formElement.bind('submit', function() {
angular.forEach(form, function(field, name) {
if (typeof name === 'string' && !name.match('^[\$]')) {
if (field.$pristine) {
return field.$setViewValue(field.$value);
}
}
});
if (form.$valid) {
return scope.$apply(attrs.submit);
}
});
}
};
});
And update your form html, for example:
<form ng-submit='justDoIt()'>
becomes:
<form name='myForm' novalidate submit='justDoIt()'>
See a full example here: http://plunker.co/edit/QVbisEK2WEbORTAWL7Gu?p=preview
Here is my global function for showing the form error messages.
function show_validation_erros(form_error_object) {
angular.forEach(form_error_object, function (objArrayFields, errorName) {
angular.forEach(objArrayFields, function (objArrayField, key) {
objArrayField.$setDirty();
});
});
};
And in my any controllers,
if ($scope.form_add_sale.$invalid) {
$scope.global.show_validation_erros($scope.form_add_sale.$error);
}
Based on Thilak's answer I was able to come up with this solution...
Since my form fields only show validation messages if a field is invalid, and has been touched by the user I was able to use this code triggered by a button to show my invalid fields:
// Show/trigger any validation errors for this step
angular.forEach(vm.rfiForm.stepTwo.$error, function(error) {
angular.forEach(error, function(field) {
field.$setTouched();
});
});
// Prevent user from going to next step if current step is invalid
if (!vm.rfiForm.stepTwo.$valid) {
isValid = false;
}
<!-- form field -->
<div class="form-group" ng-class="{ 'has-error': rfi.rfiForm.stepTwo.Parent_Suffix__c.$touched && rfi.rfiForm.stepTwo.Parent_Suffix__c.$invalid }">
<!-- field label -->
<label class="control-label">Suffix</label>
<!-- end field label -->
<!-- field input -->
<select name="Parent_Suffix__c" class="form-control"
ng-options="item.value as item.label for item in rfi.contact.Parent_Suffixes"
ng-model="rfi.contact.Parent_Suffix__c" />
<!-- end field input -->
<!-- field help -->
<span class="help-block" ng-messages="rfi.rfiForm.stepTwo.Parent_Suffix__c.$error" ng-show="rfi.rfiForm.stepTwo.Parent_Suffix__c.$touched">
<span ng-message="required">this field is required</span>
</span>
<!-- end field help -->
</div>
<!-- end form field -->
Note: I know this is a hack, but it was useful for Angular 1.2 and earlier that didn't provide a simple mechanism.
The validation kicks in on the change event, so some things like changing the values programmatically won't trigger it. But triggering the change event will trigger the validation. For example, with jQuery:
$('#formField1, #formField2').trigger('change');
I like the this approach in handling validation on button click.
There is no need to invoke anything from controller,
it's all handled with a directive.
on github
You can try this:
// The controller
$scope.submitForm = function(form){
//Force the field validation
angular.forEach(form, function(obj){
if(angular.isObject(obj) && angular.isDefined(obj.$setDirty))
{
obj.$setDirty();
}
})
if (form.$valid){
$scope.myResource.$save(function(data){
//....
});
}
}
<!-- FORM -->
<form name="myForm" role="form" novalidate="novalidate">
<!-- FORM GROUP to field 1 -->
<div class="form-group" ng-class="{ 'has-error' : myForm.field1.$invalid && myForm.field1.$dirty }">
<label for="field1">My field 1</label>
<span class="nullable">
<select name="field1" ng-model="myresource.field1" ng-options="list.id as list.name for list in listofall"
class="form-control input-sm" required>
<option value="">Select One</option>
</select>
</span>
<div ng-if="myForm.field1.$dirty" ng-messages="myForm.field1.$error" ng-messages-include="mymessages"></div>
</div>
<!-- FORM GROUP to field 2 -->
<div class="form-group" ng-class="{ 'has-error' : myForm.field2.$invalid && myForm.field2.$dirty }">
<label class="control-label labelsmall" for="field2">field2</label>
<input name="field2" min="1" placeholder="" ng-model="myresource.field2" type="number"
class="form-control input-sm" required>
<div ng-if="myForm.field2.$dirty" ng-messages="myForm.field2.$error" ng-messages-include="mymessages"></div>
</div>
</form>
<!-- ... -->
<button type="submit" ng-click="submitForm(myForm)">Send</button>
I done something following to make it work.
<form name="form" name="plantRegistrationForm">
<div ng-class="{ 'has-error': (form.$submitted || form.headerName.$touched) && form.headerName.$invalid }">
<div class="col-md-3">
<div class="label-color">HEADER NAME
<span class="red"><strong>*</strong></span></div>
</div>
<div class="col-md-9">
<input type="text" name="headerName" id="headerName"
ng-model="header.headerName"
maxlength="100"
class="form-control" required>
<div ng-show="form.$submitted || form.headerName.$touched">
<span ng-show="form.headerName.$invalid"
class="label-color validation-message">Header Name is required</span>
</div>
</div>
</div>
<button ng-click="addHeader(form, header)"
type="button"
class="btn btn-default pull-right">Add Header
</button>
</form>
In your controller you can do;
addHeader(form, header){
let self = this;
form.$submitted = true;
...
}
You need some css as well;
.label-color {
color: $gray-color;
}
.has-error {
.label-color {
color: rgb(221, 25, 29);
}
.select2-choice.ui-select-match.select2-default {
border-color: #e84e40;
}
}
.validation-message {
font-size: 0.875em;
}
.max-width {
width: 100%;
min-width: 100%;
}
To validate all fields of my form when I want, I do a validation on each field of $$controls like this :
angular.forEach($scope.myform.$$controls, function (field) {
field.$validate();
});
I have a form on my page that needs to have multiple form actions associated with it. I'm using the following script in conjunction with the following code to achieve this:
<script>
function submitForm(action)
{
document.getElementById('summary').action = action;
document.getElementById('summary').submit();
}
</script>
<form action="go-gold.php" method="post" enctype="multipart/form-data">
<input type="image" id="arrow" name="go_back" onclick="submitForm('go-gold.php')" value="go_back" src="images/arrow_back.png" class="submit_button" /><br>
<input type="image" id="arrow" name="submit_form" onclick="submitForm('registration.php')" value="submit_form" src="images/arrow.png" class="submit_button" />
</form>
The first button needs to "go back" within the same browser window (self), and the second button needs to submit the info to a new window (blank). How do I modify the code to achieve this? Putting "target" functions within the input type doesn't work, and putting the target in the Form tag makes both submit buttons submit to the same window.
Thanks!
Easy with jQuery, also you have to identical ids for two separate form elements. You should have these as distinct ids unless you want to use a class name. Php can submit forms to the same page using the $_SERVER superglobal by using $_SERVER['PHP_SELF'] as the forms action name.
<script>
$(document).ready(function() {
$(".submit_button").click(function() {
clickVal = $(".submit_button").val();
if(clickVal == 'go_back') {
//do go back stuff
}
if(clickVal == 'submit_form') {
// do actions for other page
}
});
});
</script>
<form action="go-gold.php" method="post" enctype="multipart/form-data">
<input type="image" value="go_back" src="images/arrow_back.png" class="submit_button" /><br>
<input type="image" value="submit_form" src="images/arrow.png" class="submit_button" />
</form>
What's the best solution of getting input value from Ember.TextField, after the button has been submitted?
Assume I have simple app for sending messages. I specified a view which represents input form where the user enters his message:
App.TextView = Ember.View.extend({
templateName: 'text',
submit: function(event) {
console.log(event);
}
});
Then, there is Handlebars template for this view:
<script type="text/x-handlebars" data-template-name="text">
<h1>Send the message:</h1>
<div class="send_form">
{{view Ember.TextField}}
<button type="submit">Done</button>
</div>
</script>
Basically, I need just one thing. When the user clicks on the button, I need to be notified (in the submit function or anywhere else in my app) and I need to grab the value from the TextField. How can I achieve that?
You could for example bind the value of the text field to a message property in the view.
Perhaps there is other solution, but I think this quite simple: http://jsfiddle.net/Sly7/vfaF3/
<script type="text/x-handlebars">
{{view App.TextView}}
</script>
<script type="text/x-handlebars" data-template-name="text">
<h1>Send the message:</h1>
<div class="send_form">
{{view Ember.TextField value=view.message}}
<button type="submit" {{action "submit" target=view}}>Done</button>
</div>
</script>
App = Ember.Application.create({});
App.TextView = Ember.View.extend({
templateName: 'text',
message: '',
actions: {
submit: function(event) {
console.log(this.get('message'));
}
}
});
