I want to disable chrome autocomplete in my v-form. How do I do that? I don't see a autocomplete property on the v-form.
https://next.vuetifyjs.com/en/api/v-form/
While it is a property on a normal html form
https://www.w3schools.com/tags/att_form_autocomplete.asp
By setting autocomplete="username" and autocomplete="new-password" on v-text-field you can actually turn off the autocomplete in chrome.
here is a code that worked for me:
<v-form lazy-validation ref="login" v-model="validForm" #submit.prevent="submit()">
<v-text-field
v-model="user.email"
label="Email"
autocomplete="username"
/>
<v-text-field
v-model="user.password"
label="Password"
type="password"
autocomplete="new-password"
/>
<v-btn type="submit" />
</v-form>
Edit: autocomplete isn't set as a prop in vuetify docs but if you pass something to a component which isn't defined as prop in that component, it will accept it as an attribute and you can access it through $attrs.
here is the result of the above code in vue dev tools:
and here is the rendered html:
I wasn't able to get autofill disabled with the above methods, but changing the name to a random string/number worked.
name:"Math.random()"
https://github.com/vuetifyjs/vuetify/issues/2792
use autocomplete="off" in <v-text-field
<v-text-field
autocomplete="off"
/>
Just add:
autocomplete="false"
to your <v-text-field> or any input
autocomplete="null"
This one prevents Chrome autofill feature
I have not been able to get any of the previous proposals to work for me, what I finally did is change the text-flied for a text-area of a single line and thus it no longer autocompletes
Try passing the type='search' and autocomplete="off" props.
I also ran into a similar problem. Nothing worked until I found this wonderful Blog "How to prevent Chrome from auto-filling on Vue?" by İbrahim Turan
The main catch is that we will change the type of v-text-field on runtime. From the below code you can see that the type of password field is assigned from the value fieldTypes.password. Based on focus and blur events we assign the type of the field. Also, the name attribute is important as we decide based on that in the handleType() function.
I'm also pasting the solution here:
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<template>
<div id="app">
<div v-if="isloggedin" class="welcome">
Welcome {{username}}
</div>
<div v-else id="form-wrapper">
<label for="username">Username: </label>
<input
v-model="username"
class="form-input"
type="text"
name="username"
value=""
autocomplete="off"
/>
<label for="password">Password: </label>
<input
v-model="password"
class="form-input"
:type="fieldTypes.password"
name="password"
value=""
#focus="handleType"
#blur="handleType"
autocomplete="off"
/>
<button class="block" type="button" #click="saveCredentials">
Submit Form
</button>
</div>
</div>
</template>
<script>
export default {
name: 'App',
data() {
return {
username: '',
password: '',
isloggedin: false,
fieldTypes: {
password: 'text',
}
}
},
methods: {
saveCredentials() {
this.isloggedin = true;
},
handleType(event) {
const { srcElement, type } = event;
const { name, value } = srcElement;
if(type === 'blur' && !value) {
this.fieldTypes[name] = 'text'
} else {
this.fieldTypes[name] = 'password'
}
}
}
}
</script>

I am new to ionic and I want to be able to create a gender toggle button in my application. I don't want to use checkbox but convert the checkbox to toogle as the image below.
if I am to build it in html and jQuery it will be this way
<div class="checkbox">
<input type="checkbox" name="gender" id="gender" checked />
</div>
</div>
<input type="hidden" name="hidden_gender" id="hidden_gender" value="Male" />
In jQuery
$('#gender').bootstrapToggle({
on: 'Male',
off: 'Female',
onstyle: 'success',
offstyle: 'danger'
});
$('#gender').change(function(){
if($(this).prop('checked'))
{
$('#hidden_gender').val('Male');
}
else
{
$('#hidden_gender').val('Female');
}
});
Thanks.
I think what you're looking for is <ion-toggle/>.
For documentation on this component, see: https://ionicframework.com/docs/components/#toggle
Here's a copy/paste of a line from how I'm using the tag in an Angular application:
<ion-toggle [(ngModel)]="track.isChecked" color="secondary"></ion-toggle>
I have a form, how to get the use input in the handleSubmit() method?
handleSubmit(e) {
e.preventDefault()
//how to get the user input?
}
render() {
return (
<div className="col-sm-4">
<form onSubmit={this.handleSubmit}>
<input type="text" placeholder="user"/>
<input type="text" placeholder="comments"/>
<input type="submit" hidden/>
</form>
</div>
)
}
so far, I know three solutions:
The first one, use refs, but I can see there are lots of people saying that we should avoid using it
The second one, add onChange() to each <input>, e.g.
class Example extends React.Component {
state = {
inputValue: ""
};
handleInputChanged(e) {
this.setState({
inputValue: e.target.value
});
}
render() {
return (
<div>
<input onChange={this.handleInputChanged.bind(this)} value={this.state.inputValue}>
</div>
);
}
}
this one is fine with a few inputs. But if the form has 20 input fields, then there are 20 different onChange methods?
third, use some npm module, like redux-form.
any other suggestion? Thanks
You can actually just do an onChange on the parent form like so:
onChange(e) {
switch(e.target.type) {
case 'checkbox':
this.setState({ [e.target.name]: e.target.checked });
break;
default:
this.setState({ [e.target.name]: e.target.value });
break;
}
}
// in render
<form onChange={this.onChange.bind(this)}>
<input name="foo1" />
<input name="foo2" />
<input name="foo3" />
<input name="foo4" />
<input name="foo5" />
<input name="foo6" />
<input name="foo7" />
<input name="foo8" />
</form>
There are certain libraries like https://github.com/christianalfoni/formsy-react, https://github.com/prometheusresearch/react-forms. These forms have additional functions pre written for form submitting, validations. I think using refs is a tedious and unwanted task if the form is big with the reason being that if it is controlled form you need to access the state value for controlled components which brings unnecessary complications. You can do it but it is better to use prewritten libraries.
I have a simple AddUser component and in the render function I am returning the following html:
<form ref="form" className="users-form" onSubmit={ this.handleAddNew }>
<input ref="username" type="text" name="username" placeholder="username"
value={this.state.username} onChange={function() {}} /><br />
<input ref="email" type="email" name="email" placeholder="email"
value={this.state.email} onChange={function() {}} /><br />
<button type="submit"> Add User </button>
</form>
I am binding the state of username and email to this.state which I am setting to blank in getInitialState like so:
getInitialState() {
return { username: '', email: '' };
}
I am binding state to the form so I can set it to blank after form submission.
The problem with this setup is that the form now renders as readonly.
I cannot get any user input into either text fields. What am I doing wrong?
Your input fields are controlled components, since you are using the value property. This makes the inputs readonly and they will always reflect the value, the variable (in this case, the state variable) holds. You have to explicitly setState onChange since you are setting username field as a state variable.
Read more about it here
onUserNameChange : function(e){
this.setState({username : e.target.value})
},
render: function(){
return ...
<input ref="username" type="text" name="username" placeholder="username"
value={this.state.username} onChange={this.onUserNameChange} /><br />
...
<button type="submit"> Add User </button>
</form>
}
A better way to do this is :
onChange : function(field,e){
this.setState({field: e.target.value});
},
render : function(){
return <form ref="form" className="users-form" onSubmit={ this.handleAddNew }>
<input ref="username" type="text" name="username" placeholder="username"
value={this.state.username} onChange={this.onChange.bind(this,"username")} /><br />
<input ref="email" type="email" name="email" placeholder="email"
value={this.state.email} onChange={this.onChange.bind(this,"email")} /><br />
<button type="submit"> Add User </button>
</form>
}
It looks like you saw the console warning about controlled fields needing an onChange handler and added one just to shut the warning up :)
If you replace your empty onChange handler functions with onChange={this.handleChange} and add this method to your component, it should work:
handleChange(e) {
this.setState({[e.target.name]: e.target.value})
}
(Or for people not using an ES6 transpiler:)
handleChange: function(e) {
var stateChange = {}
stateChange[e.target.name] = e.target.value
this.setState(stateChange)
}
However, if your component is an ES6 class extending React.Component (instead of using React.createClass()), you will also need to ensure the method is bound to the component instance properly, either in render()...
onChange={this.handleChange.bind(this)}
...or in the constructor:
constructor(props) {
super(props)
// ...
this.handleChange = this.handleChange.bind(this)
}
I have my form like this:
<form name="myForm">
<input name="myText" type="text" ng-model="mytext" required />
<button disabled="{{ myForm.$invalid }}">Save</button>
</form>
As you may see, the button is disabled if the input is empty but it doesn't change back to enabled when it contains text. How can I make it work?
You need to use the name of your form, as well as ng-disabled: Here's a demo on Plunker
<form name="myForm">
<input name="myText" type="text" ng-model="mytext" required />
<button ng-disabled="myForm.$invalid">Save</button>
</form>
To add to this answer. I just found out that it will also break down if you use a hyphen in your form name (Angular 1.3):
So this will not work:
<form name="my-form">
<input name="myText" type="text" ng-model="mytext" required />
<button ng-disabled="my-form.$invalid">Save</button>
</form>
Selected response is correct, but someone like me, may have issues with async validation with sending request to the server-side - button will be not disabled during given request processing, so button will blink, which looks pretty strange for the users.
To void this, you just need to handle $pending state of the form:
<form name="myForm">
<input name="myText" type="text" ng-model="mytext" required />
<button ng-disabled="myForm.$invalid || myForm.$pending">Save</button>
</form>
If you are using Reactive Forms you can use this:
<button [disabled]="!contactForm.valid" type="submit" class="btn btn-lg btn primary" (click)="printSomething()">Submit</button>
We can create a simple directive and disable the button until all the mandatory fields are filled.
angular.module('sampleapp').directive('disableBtn',
function() {
return {
restrict : 'A',
link : function(scope, element, attrs) {
var $el = $(element);
var submitBtn = $el.find('button[type="submit"]');
var _name = attrs.name;
scope.$watch(_name + '.$valid', function(val) {
if (val) {
submitBtn.removeAttr('disabled');
} else {
submitBtn.attr('disabled', 'disabled');
}
});
}
};
}
);

If you want to be a bit more strict
I'm making a form. And on one input tag is an OnClick event handler, which is opening a popup, where you can choose some stuff, and then it autofills the input tag.
That input tag is also readonly, so only right data will be entered.
This is the code of the input tag:
<input type="text" name="formAfterRederict" id="formAfterRederict" size="50" required readonly="readonly" OnClick="choose_le_page();" />
But the required attribute isn't working in Chrome. But the field is required.
Does anybody know how I can make it work?
I had same requirement as yours and I figured out an easy way to do this.
If you want a "readonly" field to be "required" also (which is not supported by basic HTML), and you feel too lazy to add custom validation, then just make the field read only using jQuery this way:
IMPROVED
form the suggestions in comments
<input type="text" class="readonly" autocomplete="off" required />
<script>
$(".readonly").on('keydown paste focus mousedown', function(e){
if(e.keyCode != 9) // ignore tab
e.preventDefault();
});
</script>

ORIGINAL
<input type="text" class="readonly" required />
<script>
$(".readonly").keydown(function(e){
e.preventDefault();
});
</script>
readonly fields cannot have the required attribute, as it's generally assumed that they will already hold some value.
Remove readonly and use function
<input type="text" name="name" id="id" required onkeypress="return false;" />
It works as you want.
Required and readonly don't work together.
But readonly can be replaced with following construction:
<input type="text"
onkeydown="return false;"
style="caret-color: transparent !important;"
required>
1) onkeydown will stop manipulation with data
2) style="caret-color: transparent !important;" will hide cursor.
3) you can add style="pointer-events: none;" if you don't have any events on your input, but it was not my case, because I used a Month Picker. My Month picker is showing a dialog on click.
This is by design. According to the official HTML5 standard drafts, "if the readonly attribute is specified on an input element, the element is barred from constraint validation." (E.g. its values won't be checked.)
Yes, there is a workaround for this issue. I found it from https://codepen.io/fxm90/pen/zGogwV site.
Solution is as follows.
HTML File
<form>
<input type="text" value="" required data-readonly />
<input type="submit" value="Submit" />
</form>
CSS File
input[data-readonly] {
pointer-events: none;
}
If anyone wants to do it only from html, This works for me.
<input type="text" onkeydown="event.preventDefault()" required />
I think this should help.
<form onSubmit="return checkIfInputHasVal()">
<input type="text" name="formAfterRederict" id="formAfterRederict" size="50" required readonly="readonly" OnClick="choose_le_page();" />
</form>
<script>
function checkIfInputHasVal(){
if($("#formAfterRederict").val==""){
alert("formAfterRederict should have a value");
return false;
}
}
</script>
You can do this for your template:
<input required onfocus="unselect($event)" class="disabled">
And this for your js:
unselect(event){
event.preventDefault();
event.currentTarget.blur();
}
For a user the input will be disabled and required at the same time, providing you have a css-class for disabled input.
Based on answer #KanakSinghal but without blocked all keys and with blocked cut event
$('.readonly').keydown(function(e) {
if (e.keyCode === 8 || e.keyCode === 46) // Backspace & del
e.preventDefault();
}).on('keypress paste cut', function(e) {
e.preventDefault();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" class="readonly" value="test" />
P.S. Somebody knows as cut event translate to copy event?
Required and readonly don't work together.
Although you can make two inputs like this:
<input id="One" readonly />
<input id="Two" required style="display: none" /> //invisible
And change the value Two to the value that´s inside the input One.
I have the same problem, and finally I use this solution (with jQuery):
form.find(':input[required][readonly]').filter(function(){ return this.value === '';})
In addition to the form.checkValidity(), I test the length of the above search somehow this way:
let fcnt = $(form)
.find(':input[required][readonly]')
.filter(function() { return this.value === '';})
.length;
if (form.checkValidity() && !fcnt) {
form.submit();
}
function validateForm() {
var x = document.forms["myForm"]["test2"].value;
if (x == "") {
alert("Name missing!!");
return false;
}
}
<form class="form-horizontal" onsubmit="return validateForm()" name="myForm" action="" method="POST">
<input type="text" name="test1">
<input type="text" disabled name="test2">
<button type="submit">Submit</button>
</form>
