I have a button which looks like an on off Button
Button is by default on but when user will click it should get off and when it is clicked it should disable the input field
my button is as
Button
<input type="checkbox" class="make-switch" id="on_off" name="double_optin" checked data-on-text="on" data-off-text="off">
Input field which i want to be disabled if above button clicks
<div class="col-md-4 FullName">
<input type="text" class="form-control" name="email" value="{{ isset($student->email) ? $student->email : '' }}" required />
</div>
My Jquery code is as
$('#on_off').click(function(){
$('.FullName').prop('disabled', true);
});
I took above help from Disable Input field
Help Please its not working for me
First of your code is missing something. Like the control with class FullName
You can get the value of the checkbox by using $('#on_off').is(':checked') or in this case $(this).is(':checked') because we are using $('#on_off') click event.
Since you dont have a "Fullname" class anywhere in your example I added email to the Id field of the input
$('#on_off').click(function() {
$('.FullName [name="email"]').attr('disabled', $(this).is(':checked') ? false : true);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="checkbox" class="make-switch" checked id="on_off" name="double_optin" data-on-text="on" data-off-text="off">
<div class="col-md-4 FullName">
<input type="text" class="form-control" name="email" value="disable me by click on checkbox" required />
</div>
Please try this code.
Here is your updated code:
<input type="checkbox" class="make-switch" id="on_off" name="double_optin" checked data-on-text="on" data-off-text="off">
<div class="col-md-4 FullName">
<input type="text" class="form-control" name="email" value="{{ isset($student->email) ? $student->email : '' }}" id= "email"required />
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script>
$(document).ready(function() {
$('#on_off').change(function() {
//alert();
if ($(this).prop('checked')) {
$('.FullName input').prop('disabled', false);
}
else {
$('.FullName input').prop('disabled', true);
}
});
});
</script>
Hope, this may help you.
use .attr('disabled',true) or .removeAttr('disabled') instead of .prop('disabled', true); if not working.
This is the easiest you can get.
Create a checkbox. In click event of checkbox, pass its state as a boolean to buttons disabled value.
Though I would suggest to use ready made toggle button. Link is here
$(document).ready(function(){
$(":checkbox").change(function(){
$(":button").prop("disabled",$(this).is(":checked"));
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type=checkbox />
<input type=button value=Target />

I'm trying to have a checkbox next to a form text-input field. The checkbox can be ticked on/off normally, however when clicking on the text-input field, the checkbox should be automatically ticked as well.
I tried this with putting the text-input inside the label for the checkbox, but it doesn't work. It works fine when I use normal text instead of the input-field:
<input type="checkbox" id="box">
<label for="box">
<input type="text">
</label>
How can I achieve this with HTML/JS? I'm working in the context of a VueJS plugin.
The click action of <input> (focus & start editing) overrides <label>'s, so you'll have to use JS:
document.querySelector('#text').addEventListener('click', ()=>{
document.querySelector('#box').checked=true
})
<input type="checkbox" id="box">
<input type="text" id="text">
you can use jquery to achieve this:
HTML:
<input type="checkbox" id="box">
<label for="box"></label>
<input type="text" id="mytextinput">
JQuery:
$('#mytextinput').focus(function(){
$('#box').prop( "checked", true ); // true checks the checkbox false unchecks.
});
Simply add a listener to the text input that checks the box.
const checkbox = document.querySelector('#box');
const input = document.querySelector('input[type="text"]');
input.addEventListener('click', () => {
checkbox.checked = true;
});
<input type="checkbox" id="box">
<label for="box">
<input type="text">
</label>
You can do this easily by setting an onclick attribute on text field like:
<input type="checkbox" id="box">
<label for="box">
<input type="text" onclick="box.checked = true">
</label>
document.querySelector("#box").addEventListener('click',function(){
document.querySelector("#checkbox").checked = true;
});
<div>
<input type="checkbox" id="checkbox">
<input type="text" id="box">
</div>
This is how my razor code looks like
<form asp-action="Save" asp-controller="ClassesHeld" method="post">
<input asp-for="ClassHeldId" value="#Model.ClassHeldId" hidden />
<div class="form-group">
<label>Student</label>
<input asp-for="#Model.Student" value="#Model.Student" class="form-control" readonly />
</div>
<div class="form-group">
<label>Grade</label>
<input id="Grade"asp-for="Grade" type="number" value="#Model.Grade" class="form-control" min="0" max="5" />
</div>
<div class="form-group">
<label>Attendance</label>
<input id="Attendance" class="form-check-input" asp-for="Attendance" type="checkbox"/>
</div>
<button class="btn btn-primary" type="submit" value="Save">Save</button>
</form>
<script>
$("#Attendance").on("change", function () {
$("#Grade").attr("disabled", this.checked);
});
</script>
Yet for some reason, clicking on the checkbox does nothing at all. I have tried this with simple script as well, and that didn't work either.
document.getElementById('Attendance').onchange = function () {
document.getElementById('Grade').disabled = this.checked;
};
Neither of these worked.
I have even copied some solutions from here (one of them is that last simple scrip with document.getElementbyId, and none of it worked. I have to be missing something simple, but I've been looking at this for the past hour and I still can't figure it out.
I apologize if the question is stupid or noob-level. But I am getting desperate.
EDIT: Simply to add more information, this form works perfectly fine when submitting data, controller saves the stuff to the database... Everything works fine, just not the part where it disables the ability to edit the Grade if the student has not attended.
So the objective, is to disable the input field when the checkbox for "attendance" is checked
The .attr() method only manage string; So if you want to change an attribut like disabled or even checked with a boolean or something else, you have to use the prop method.
For more information check this post :
.prop() vs .attr()
You can execute the snippet below.
$("#Attendance").on("change", function () {
$("#Grade").prop("disabled", this.checked)
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form asp-action="Save" asp-controller="ClassesHeld" method="post">
<input asp-for="ClassHeldId" value="#Model.ClassHeldId" hidden />
<div class="form-group">
<label>Student</label>
<input asp-for="#Model.Student" value="#Model.Student" class="form-control" readonly />
</div>
<div class="form-group">
<label>Grade</label>
<input id="Grade"asp-for="Grade" type="number" value="#Model.Grade" class="form-control" min="0" max="5" />
</div>
<div class="form-group">
<label>Attendance</label>
<input id="Attendance" class="form-check-input" asp-for="Attendance" type="checkbox"/>
</div>
<button class="btn btn-primary" type="submit" value="Save">Save</button>
</form>
<script>
</script>
I think you actually need to remove the disabled attribute when you don't want it. Maybe try this:
$(document).ready(function() {
$("#Attendance").on("change", function () {
if (this.checked) {
$("#Grade").attr("disabled", true);
} else {
$("#Grade").removeAttr("disabled");
}
});
});
Trying to set radio button checked when click on textarea.
There is a label for radio button and inside the label there is a textarea so what i need is that when clicking on the textarea to write the input will be checked.
<input type="radio" name="msg_form" id="invite0" value="0" <? if ($msg_form == 0) { echo 'checked'; } ?>>
<label for="invite0">
<textarea class="selfmessage" for="invite0" oninput="replaceName(this)" style="height: auto !important;" name="self_invite" type="text" placeholder="write something..."></textarea>
</label>
You can use keyup or input or change or focus or whatever you like as a trigger. here is a list of often used trigger
$('.selfmessage').on('focus', function(e) {
$('#invite0').prop('checked', true);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="radio" name="msg_form" id="invite0" value="0"><label for="invite0">
<textarea class="selfmessage" for="invite0" style="height: auto !important;" name="self_invite" type="text" placeholder="write something..."></textarea>
</label>
You can achieve this by using parent() to get the label wrapping the textarea, then prev() to get the input and prop() to set it to checked:
$('.selfmessage').on({
'focus': function() {
$(this).parent().prev(':radio').prop('checked', true);
},
'input': replaceName
});
function replaceName() {
// your logic here...
}
.selfmessage {
height: auto;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="radio" name="msg_form" id="invite0" value="0">
<label>
<textarea class="selfmessage" name="self_invite" type="text" placeholder="write something..."></textarea>
</label>
Note that the functionality of the label here is pretty much entirely redundant given your example code. I only left it in in case your UI styling depends on it. If it doesn't I'd suggest removing it.
Also note that I removed the oninput event attribute and changed it to an unobtrusive handler, and also changed the inline styling to external CSS. Inline JS and CSS should always be avoided where possible.
$('.selfmessage').on('keyup', function(e) {
if($('.selfmessage').val().length>0){
$('#invite0').prop('checked', true);
}else{
$('#invite0').prop('checked', false);
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="radio" name="msg_form" id="invite0" value="0"><label for="invite0">
<textarea class="selfmessage" for="invite0" style="height: auto !important;" name="self_invite" type="text" placeholder="write something..."></textarea>
</label>
Add a keyup event to textarea then check the textarea empty or not. if not empty enable checkbox else diable it.
$('#id-textarea').click(function(){
$("#id-checkbox").attr("checked", true);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<html>
<input type="checkbox" id="id-checkbox"/>
<textarea id="id-textarea"></textarea>
</html>

How to check a radio button with jQuery?
(33 answers)
Closed 6 years ago.
I have this portion of code:
var checkout_options = $("#checkout").find("input[type='radio']");
$('#button-account').on('click', function () {
alert(checkout_options.value);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.0/jquery.min.js"></script>
<div id="checkout">
<p>Checkout Options:</p>
<label for="register">
<input type="radio" name="account" value="register" id="register" checked>
<b>Register Account</b></label>
<br>
<label for="guest">
<input type="radio" name="account" value="guest" id="guest">
<b>Guest Checkout</b>
</label>
<input type="button" value="Continue" id="button-account">
</div>
What I want it is to get the value of the selected radio button but with my code I only get the first radio button value, the second radio does not work.
Kindly help me fix the error.
You need to use this to refer the element inside the callback. So get value by using this.value or $(this).val() method. Although avoid :checked pseudo-class selector otherwise it only selects the first element.
var selected = $("#checkout").find("input[type='radio']");
selected.change(function(){
alert(this.value);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.0/jquery.min.js"></script>
<div id="checkout">
<p>Checkout Options:</p>
<label for="register">
<input type="radio" name="account" value="register" id="register" checked>
<b>Register Account</b></label>
<br>
<label for="guest">
<input type="radio" name="account" value="guest" id="guest">
<b>Guest Checkout</b>
</label>
</div>
You can make it simpler using :radio pseudo-class selector
$("#checkout :radio").change(function() {
alert(this.value);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.0/jquery.min.js"></script>
<div id="checkout">
<p>Checkout Options:</p>
<label for="register">
<input type="radio" name="account" value="register" id="register" checked>
<b>Register Account</b>
</label>
<br>
<label for="guest">
<input type="radio" name="account" value="guest" id="guest">
<b>Guest Checkout</b>
</label>
</div>
Your handler is only being attached to the radio button that is checked, so no handler exists for the second radio button. Attach a handler to both radio buttons:
var $radioBtn = $( "#checkout" ).find( "input[type='radio']" );
$radioBtn.on( 'change', function() {
if ( this.checked ) {
alert( this.value );
}
});
It didn't work, because you register the event handler for the initially checked value only. This is how to make it dynamically reflect the value change:
var selected = $("#checkout").find("input[name='account']");
selected.change(function(){
alert($(this).val());
});
This also makes sure that only the current radio button group is included, so you can have additional ones.
Jsfiddle:
https://jsfiddle.net/sjmhdasw/
Just use
$("input[type='radio']").on("change", function() {
console.log(this.id + " checked !");
});
It binds an event listener on all the inputs of type radio !
No need to store the selectors inside a variable (unless you're doing something with it, somewhere else in your code)
Given the following code (yes, i know it is perhaps irrelevant in yii, but I added the tag so I update the question with the actual generated html):
<script>
$(function(){
$('#widgetId-form input[name="valueType"]').change(function(){
if ($(this).is(":checked"))
{
console.log("habilitando "+$(this).data("class"));
$("."+$(this).data("class")).prop("disabled", false);
}
else
{
console.log("deshabilitando "+$(this).data("class"));
$("."+$(this).data("class")).prop("disabled", true);
}
}).change();
});
</script>
<div id="widgetId-dialog">
<form id="widgetId-form" action="/support/test" method="post">
<div>
<input id="valueType-single" value="single" data-class="singleValueField" checked="checked" type="radio" name="valueType" />
<label for="single">Valor simple</label>
<input size="6" class="singleValueField" type="text" value="" name="singleValue" id="singleValue" />
</div>
<div>
<input id="valueType-range" value="range" data-class="rangeValueField" type="radio" name="valueType" />
<label for="range">Rango (inicio:fin:intervalo)</label>
<input size="6" class="rangeValueField" type="text" value="" name="rangeValue_start" id="rangeValue_start" />:<input size="6" class="rangeValueField" type="text" value="" name="rangeValue_end" id="rangeValue_end" />:<input size="6" class="rangeValueField" type="text" value="" name="rangeValue_interval" id="rangeValue_interval" />
</div>
</form>
</div>
It doesn't trigger change() when a radio becomes unchecked. This implies: controls are disabled only on initialization (.ready()). change() is not triggered individually by controls losing the checkmark.
Question: how can I detect when a radio button loses the checkmark?
This is a conceptional problem. The radio buttons are seen somehow like one element. For closer information look at Why does jQuery .change() not fire on radio buttons deselected as a result of a namesake being selected?.
So the change-event will always only fire on the newly selected element and not on the deselected radios. You could fix your code like this:
$(function(){
$('#widgetId-form input[name="valueType"]').change(function(){
//could be also hardcoded :
$('input[name="' + $(this).attr("name") + '"]').each(function(){
if ($(this).is(":checked"))
{
console.log("habilitando "+$(this).data("class"));
$("."+$(this).data("class")).prop("disabled", false);
}
else
{
console.log("deshabilitando "+$(this).data("class"));
$("."+$(this).data("class")).prop("disabled", true);
}
});
});
$('#widgetId-form input[name="valueType"]:first').change();
});
