I am going through the bootstrap 4 documentation.
What purpose does it do to set the autocomplete tag to off?
Is this something needed for bootstrap, or is it just good practice?
<div class="btn-group btn-group-toggle" data-toggle="buttons">
<label class="btn btn-secondary active">
<input type="radio" name="options" id="option1" autocomplete="off"
checked> Active
</label>
</div>
Unlike other browsers, Firefox by default persists the dynamic checked state of an <input> across page loads. Use the autocomplete attribute to control this feature.
https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/radio
The docs are confused on this. The link posted by #dontangg states autocomplete is used on radio buttons by Firefox, but the main doc page for the <input> element type explicitly says the opposite:
https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input#attr-autocomplete
It probably doesn't hurt to include it but to me it doesn't make much sense for it to do anything on radio buttons.
It's about the browser stage.
<script type="text/javascript">
function fnPickedFlow(){
return #('input[name=pickedFlow]:checked').val();
}
$( document ).ready(function() {
console.log( "pickedFlow:" + fnPickedFlow() );
// The first time return "one"
// The second time return "two"
});
</script>
<input type="radio" name="pickedFlow" value="one" checked/>
<input type="radio" name="pickedFlow" value="two" />
The first time when page loads, Radio button one is selected by default. When changing the selection to two and submitting, the redirection happens. And user click browser back button (javascript:history.back()) to come back to this page, pickedFlow is pointing to one but the selected button in UI is two.
Change code add autocomplete off for each of radio button to avoid the situation:
<script type="text/javascript">
function fnPickedFlow(){
return #('input[name=pickedFlow]:checked').val();
}
$( document ).ready(function() {
console.log( "pickedFlow:" + fnPickedFlow() );
// Always return "one"
});
</script>
<input type="radio" name="pickedFlow" value="one" autocomplete="off" checked/>
<input type="radio" name="pickedFlow" value="two" autocomplete="off" />

Radio inputs are not compatible with autocomplete. However, it doesn’t hurt anything to have it there. It’s up to you if you want to keep it.

I have a simple (mostly-working) submission form:
<form action="http://127.0.0.1:3000/books" method="POST" class="addBook">
<input type="text" placeholder="Title" name="title" required>
<input type="text" placeholder="ISBN" name="isbn" required>
<button id="submitBook" type="submit" onclick="addingBooks()">Submit</button>
</form>
My form properly adds the input values to my database and it then appears in the DOM when I go back and refresh the page.
I have applied an preventDefault() function in my JavaScript code for the 'addingBooks()' function to stop it from submitting twice, but I am still unable to stop it from forwarding to the action page after submission which only shows the JSON of the submitted data.
If you need more then please let me know.
To prevent the default action of an event you'll need an event object to call preventDefault on. Some browser do in fact have a global event object but that might not be reliable.
The simplest option would be to return false from the onlick event, not from a function you call in it
<button id="submitBook" type="submit" onclick="addingBooks();return false;">Submit</button>
another simple and better solution would be to make the button be a regular button instead of a submit button and remove the preventDefault from addingBooks.
<button id="submitBook" type="button" onclick="addingBooks()">Submit</button>
another and even better solution would be to not use the onclick attribute at all, use the addEventListener function
document.getElementById('submitBook').addEventListener("click", function(e){
e.preventDefault();
//other stuff
});
This prevent enter submit,but at the moment prevent enter in inputs.
I need that enterkey work in inputs but not submit form.
<template id="form-template">
<form action="save-passport" #keypress.enter.prevent method="post" enctype="application/x-www-form-urlencoded" >
<input type="submit" v-show="loaded" v-on:click="saveForm" value="Save" />
<input type="text" required="required" name="field-11" >
<select required="required" name="field-13"><option value=""></option>
</select>
</form>
</template>
Had the same problem. Solution I did was to put the submit method on the opening form tag. Then no need for the input/button type="submit" inside the form at the bottom.
<form class="form" action="" method="POST" #submit.enter.prevent="createForm()">
Also other options available on inputs:
#keydown.enter.prevent
#keyup.enter.prevent
#submit.enter.prevent
I did it this way
first i removed vue modifiers from form tag.
second i chaged type of input from submit to button
and third this my saveForm function
saveForm:function(){
if (someCondition){
event.preventDefault();
}else{
document.forms[0].submit();
}
}
You need to use the prevent modifier. Another thing, your webpage itself must have the focus. Meaning, if you just visit the webpage, prevent won't work. But, if you click somewhere in the form, prevent will work for you.
You can still submit the form via JavaScript using something like document.forms[0].submit();
When focus is placed into an input of this form, iPhone shows input keyboard and Go button, which acts as submit. Is it possible to change the label to e.g. "Create"? I tried value, title or name but none of those work.
<form>
<input name="foo" type="text"/>
<input type="submit" name="Create" value="Create" title="Create"/>
</form>
No, something like this is not possible.
I know how to detect which submit button was clicked when I know the name values of each of the buttons. But what if the names are dynamic or defined by another component?
For example, here I can simply check the POST data from this <form> for either alpha or bravo:
<form>
<input type="submit" name="alpha" value="Alpha">
<input type="submit" name="bravo" value="Bravo">
</form>
But that's only because I know I should be looking for those names.
Is there a best practice for handling this type of situation? (Perhaps by rendering an element <input type="hidden" name="submit-button-names" value="dynamic_name1|dynamic_name2|etc">.) I would like a solution that doesn't require JavaScript.
Presuming you have control over the JSP displaying these buttons, just prefix the button names with a string you can look for in the POSTed data. For example prepending "dynamicbutton_" to all of the names like this
<form>
<input type="submit" name="dynamicbutton_alpha" value="Alpha">
<input type="submit" name="dynamicbutton_bravo" value="Bravo">
</form>
Then in your Servlet, look for values with this prefix by calling ServletRequest.getAttributeNames()
You could write a custom tag to set the different inputs to your form based on a list of parameters you give to the tag.
You would end up with the HTML looking something like this:
<form method="POST" action="SelectColour.do">
<p>Select your favorite colour: </p>
<formTags:select name='colour' size='1' optionsList='${applicationScope.colourList}'/>
<input type="SUBMIT" value="Click here to submit">
</form>
Here's a decent guide to creating custom tags.
I have set up a bootstrap modal with a form inside it, I just noticed that when I press the Enter key, the modal gets dismissed.
Is there a way not to dismiss it when pressing Enter?
I tried activating the modal with keyboard:false, but that only prevents dismissal with the ESC key.
I just had this problem too.
My problem was that i had a close button in my modal
<button class="close" data-dismiss="modal">×</button>
Pressing enter in the input field caused this button to be fired. I changed it to an anchor instead and it works as expected now (enter submits the form and does not close the modal).
<a class="close" data-dismiss="modal">×</a>
Without seeing your source, I can't confirm that your cause is the same though.
Just add the type="button" attribute to the button element, some browsers interpret the type as submit by default.
https://developer.mozilla.org/en-US/docs/Web/HTML/Element/button#Attributes
This applies for all the buttons you have in the modal.
<button type="button" class="close" data-dismiss="modal">×</button>
I had this problem even after removing ALL buttons from my Bootstrap Modal, so none of the solutions here helped me.
I found that a form with a single text field would cause the browser to do a form submit (and result in dismiss), if you hit Enter while keyboard focus is on the text field. This seems to be more of a browser/form issue than anything with Bootstrap.
My solution was to set the form's onsubmit attribute to onsubmit="return false"
This may be a problem if you are actually using the submit event, but I'm using JS frameworks that generate AJAX requests rather than doing a browser submit, so I prefer disabling submit entirely. (It also means I don't have to manually tweak every form element that might trigger a submit).
More info here: Bootstrap modal dialogs with a single text input field always dismiss on Enter key
I had same problem, and i solved it with
<form onsubmit="return false;">
but there is one more solution, you can add dummy invisible input, so your form would look like this:
<form role="form" method="post" action="submitform.php">
<input type="text" id="name" name="name" >
<input type="text" style="display: none;">
</form>
You can put the login button before the cancel button and this would solve the issue you are having as well.
<div class="modal-footer">
<button type="submit" class="btn primary">Login</button>
<button type="submit" class="btn" data-dismiss="modal">Cancel</button>
</div>
I had a similar experience just now and the way I solved it was instead of using a tag, I changed the tag to an tag with type="button". This seemed to solve the problem of pressing the "enter" key and dismissing the bootstrap modal.
I had this problem too and I solved it this way. I added onsubmit to form. I also wanted to be able to use enter key as a saving key so I added save_stuff() javascript to onsubmit. return false; is used to prevent the form submit.
<form onsubmit="save_stuff(); return false;">
...
</form>
<script>
function save_stuff(){
//Saving stuff
}
</script>
