I have some radio button so in that some Null Value are present so i want to remove it by identify dynamically
<input type="radio" name="Result_radio" id="Result_0" >Group</input>
<input type="radio" name="Result_radio" id="Result_1" >individual</input>
<input type="radio" name="Result_radio" id="Result_2" >Null Value</input>
Input type radio don't have closing tags.
Use label for the values
<input type="radio" name="Result_radio" id="Result_0" > <label>Group</label>
<input type="radio" name="Result_radio" id="Result_1" ><label>individual</label>
<input type="radio" name="Result_radio" id="Result_2" ><label>Null Value</label>
jQuery:
$('input:radio').each(function() {
if($(this).next('label').text() == 'Null Value'){
$(this).next('label').remove();
$(this).remove();
}
});
Fiddle
Do note that your HTML is invalid, and will be interpreted by browsers as:
<input type="radio" name="Result_radio" id="Result_0">Group
<input type="radio" name="Result_radio" id="Result_1">individual
<input type="radio" name="Result_radio" id="Result_2">Null Value
Therefore, we have to check for the next text node after each input:
// For each radio button
$('input:radio').each(function() {
// If trimmed text after the current radio button is 'Null Value',
if($.trim(this.nextSibling.nodeValue) == 'Null Value') {
// Remove the text node
$(this.nextSibling).remove();
// Remove current radio button
$(this).remove();
}
});

I have a check box that I want to enable these radio buttons. what I have does not work. how can I JS that?
im new. :(
var sipch = document.querySelector("input[name=sip]");
sipch.addEventListener( 'change', function() {
if(sipch.checked) {
document.getElementById("protocol").disabled=false;
} else {
document.getElementById("protocol").disabled=true;
}
});
<input type="checkbox" name="sip" onsubmit="goPFive(event)" method="get">do this?
<input type="radio" class="testD" name="protocol" value="udp" disabled checked/>UDP
<input type="radio" class="testD" name="protocol" value="tcp" disabled />TCP
group your radio input with fieldset then set disabled attribute at fieldset element
<fieldset id="radioWrapper" disabled>
<input type="radio" name="protocol" class="testD" value="udp"/>UDP
<input type="radio" name="protocol" class="testD" value="tcp" />TCP
</fieldset>
I would like to unselect a radio button when I click on the label and the following code only works as expected if I click on the button itself.
How to link the behaviour of the label to the button?
<label>
<input type="radio" name="choice" value="HTML" onMouseDown="this.__chk = this.checked" onClick="if (this.__chk) this.checked = false" /> Learn HTML
</label>
<label>
<input type="radio" name="choice" value="Java" onMouseDown="this.__chk = this.checked" onClick="if (this.__chk) this.checked = false"/> Learn JavaScript
</label>
Radio buttons don't work like you are thinking they do. To deselect one you need to either select another with the same name attribute or reset the form. The functionality that you are describing fits more with a checkbox than a radio button. See https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input/radio for the specs. You may also want to take a look at this question/answer: Reset Particular Input Element in a HTML Form.
Also, there is no need to wrap your label tag around the input. The for attribute takes care of the linking.
If you want to de-select a radio button, you will need to reset the form.
form {
display: flex;
flex-direction: column;
}
<form>
<label for="ckb-01">
<input id="ckb-01" type="radio" name="choice" value="HTML" />
Learn HTML
</label>
<label for="ckb-02">
<input id="ckb-02" type="radio" name="choice" value="Java" />
Learn JavaScript
</label>
<label for="ckb-03">
<input id="ckb-03" type="radio" name="choice" value="Java" />
Learn CSS
</label>
<input type="reset" />
</form>
use the attribut for in the label
<label for='idHTML'>Learn HTML </label>
give the radio the id equivalent
<input id='idHTML' type="radio" name="choice" />
what do you mean by this.__chk
onMouseDown="this.__chk = this.checked"
onClick="if (this.__chk) this.checked = false"
if you wanna select just one you could use simply type radio with group the options with one name='choice'
if you want check and uncheck multiple choices you could use checkbox
After many attempts I finally managed to code a working solution with some javascript.
The problem is that as soon as the radio button is clicked its state changes. the previous value needs to be stored in order to know if it has to be unselected or not.
<main id="form">
<label >
<input type="radio" name="rad" id="Radio0" />Learn Html
</label>
<br><br>
<label>
<input type="radio" name="rad" id="Radio1" />Learn CSS
</label>
<br><br>
<label>
<input type="radio" name="rad" id="Radio2" />Learn Java
</label>
</main>
<script>
let buttons = document.querySelectorAll('#form input');
for (button of buttons){
button.dataset.waschecked="false";
button.addEventListener('click', myFunction, false);
}
function myFunction(e) {
if (e.originalTarget.dataset.waschecked == "false"){
for (button of document.querySelectorAll('#form input')){
button.dataset.waschecked = "false";
}
e.originalTarget.dataset.waschecked = "true";
e.originalTarget.checked =true;
}else {
for (button of document.querySelectorAll('#form input')){
button.dataset.waschecked = "false";
}
e.originalTarget.checked =false;
}
}
</script>
Any suggestion to improve this code is welcome.
how do I select all checkboxes when the first radio input is selected & uncheck all checkboxes when the second radio input is selected? (Javascript)?
I've looked into previous similar questions on here, but they all seem to be about using checkboxes rather than radio buttons, or there aren't ways to unselect.
<input type="radio" class="permission" name="permission" value="select" /> Select All<br>
<input type="radio" class="permission" name="permission" value="deselect" /> Deselect All<br>
<input type="checkbox" class="custom-selector" /> Checkbox 1
<input type="checkbox" class="custom-selector" /> Checkbox 2
<input type="checkbox" class="custom-selector" /> Checkbox 3
Get a list of HTML nodes by class using document.querySelectorAll(). Iterate the radios list using NodeList.forEach(), and add a change event listener to each radio button. Whenever the listener is called, iterate the checkboxes array with NodeList.forEach(), and update the checked value of each element:
var checkboxes = document.querySelectorAll('.custom-selector');
var radios = document.querySelectorAll('.permission');
radios.forEach(function(el) {
el.addEventListener('change', function(e) {
var checked = el.value === 'select';
checkboxes.forEach(function(el) {
el.checked = checked;
});
});
});
<input type="radio" class="permission" name="permission" value="select" /> Select All<br>
<input type="radio" class="permission" name="permission" value="deselect" /> Deselect All<br>
<input type="checkbox" class="custom-selector" /> Checkbox 1
<input type="checkbox" class="custom-selector" /> Checkbox 2
<input type="checkbox" class="custom-selector" /> Checkbox 3
You can do it using JQuery.
$('.permission').click(function() {
$('.custom-selector').prop('checked', $(this).val() == 'select');
});
See below Code Snippet
$('.permission').click(function() {
$('.custom-selector').prop('checked', $(this).val() == 'select');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="radio" class="permission" name="permission" value="select" /> Select All<br>
<input type="radio" class="permission" name="permission" value="deselect" /> Deselect All<br>
<input type="checkbox" class="custom-selector" /> Checkbox 1
<input type="checkbox" class="custom-selector" /> Checkbox 2
<input type="checkbox" class="custom-selector" /> Checkbox 3
function handleChange(e) {
if (e.target.value == "select") {
handleCheckUncheck(true);
}
if (e.target.value == "deselect") {
handleCheckUncheck(false);
}
}
function handleCheckUncheck(value) {
document.querySelectorAll("input[type='checkbox']").forEach(function(val) {
val.checked = value;
})
}
document.querySelectorAll("input[type='radio']").forEach(function(val) {
val.addEventListener("change", handleChange);
})
<input type="radio" class="permission" name="permission" value="select" /> Select All<br>
<input type="radio" class="permission" name="permission" value="deselect" /> Deselect All<br>
<input type="checkbox" class="custom-selector" /> Checkbox 1
<input type="checkbox" class="custom-selector" /> Checkbox 2
<input type="checkbox" class="custom-selector" /> Checkbox 3
You can do it in a simple way without using jQuery.
Add a checkbox whose status will be set for others.
<label><input type="checkbox" onClick="toggle(this)" /> Select All</label>`
And use this javascript function that will check other checkboxes with the 'custom-selector' class:
function toggle(source) {
checkboxes = document.getElementsByName('custom-selector[]');
for(var i=0, n=checkboxes.length;i<n;i++) {
checkboxes[i].checked = source.checked;
}
}
If someone checks the "Select All" checkbox, all others will also be selected. If it deselects, the effect will be the same.

I agree with #OriDrori's answer, You don't need to load jQuery to do such a simple task.
I have a checkbox with (20) choices and also (20) input fields , i need : when user choose one or more option, put value of checked checkbox in a separate input field else put (0)
I tried the following and it working when user chose only one option.
$(".cont").change(function() {
if($('.cont :checked').val() == "1") {
$('#q1').val('1');
}else{
$('#q1').val('0');
}
if($('.cont :checked').val() == "2") {
$('#q2').val('2');
}else{
$('#q2').val('0');
}
if($('.cont :checked').val() == "3") {
$('#q1').val('3');
}else{
$('#q3').val('0');
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="cont">
<input type="checkbox" value="1">
<input type="checkbox" value="2">
<input type="checkbox" value="3">
</div>
<input id="q1" type="text" >
<input id="q2" type="text" >
<input id="q3" type="text" >
You can combine the uses of .val() and .is(':checked').
$('#q' + $(this).val()) will select the correct text input.
$(this).is(':checked') ? $(this).val() : 0 will put your checkbox value inside your input if checked, 0 if not.
$('.cont input[type="checkbox"]').change(function() {
$('#q' + $(this).val()).val($(this).is(':checked') ? $(this).val() : 0);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="cont">
<input type="checkbox" value="1">
<input type="checkbox" value="2">
<input type="checkbox" value="3">
</div>
<input id="q1" type="text">
<input id="q2" type="text">
<input id="q3" type="text">
You need to follow these steps and use much more managed code to achieve this:
Detect change on checkbox checked/unchecked
Get the value of the checkbox and since the id of the input element
is prefixed with q and the value of the checkbox, get the id
first
Use this id to fill the value in the input element.
In addition, you can check for uncheck of the checkbox and substitute
the previous value with null.
$('input[type="checkbox"]').change(function() {
var checkedValue = $(this).val();
var inputElemId = "q"+checkedValue;
if($(this).is(':checked')){
$('#'+inputElemId).val(checkedValue);
} else {
$('#'+inputElemId).val(null);
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="cont">
<input type="checkbox" value="1">
<input type="checkbox" value="2">
<input type="checkbox" value="3">
</div>
<input id="q1" type="text" >
<input id="q2" type="text" >
<input id="q3" type="text" >
In my dashboard there are 4 radio button. I need show only one in one condition. And each button has different values
<input type="radio" name="payment_method" id="payment_method" value="Online-Others">
<input type="radio" name="payment_method" id="payment_method" value="Cash">
<input type="radio" name="payment_method" id="payment_method" value="wallet">
<input type="radio" name="payment_method" id="payment_method" value="online">
Here I need to show only cash button. Should I make different ids for each button? Or using this am I able to show that?
You can remove elements by values with a attribute selector:
// removes all 'payment_method' radios where 'value' is not 'Cash'
$(".payment_method[value!=Cash]").remove();
But as ids are unique in HTML, you could (must) better change them:
<input type="radio" name="payment_method" id="payment_method_others" value="Online-Others">
<input type="radio" name="payment_method" id="payment_method_cash" value="Cash">
<input type="radio" name="payment_method" id="payment_method_wallet" value="wallet">
<input type="radio" name="payment_method" id="payment_method_online" value="online">
JS:
// removes all 'payment_method' radios where 'id' is not 'payment_method_cash'
$(".payment_method:not(#payment_method_cash)").remove();
No need to add ID or Class
$('input[name=payment_method][value=wallet]').prop('checked',true); //if you need to highlight "wallet"
$('input[name=payment_method][value=Cash]').prop('checked',true); //if you need to highlight "Cash"
Your question in not much clear for me, are you expecting something like this ?
$('#payment_method_cash').on('change', function() {
// Show cash payment button and options.
console.log('Cash option checked : ' + $(this).prop('checked'));
});
$('#payment_method_wallet').on('change', function() {
// Show wallet payment button and options.
console.log('wallet option checked : ' + $(this).prop('checked'));
});
$('#payment_method_online').on('change', function() {
// Show online payment button and options.
console.log('online option checked : ' + $(this).prop('checked'));
});
$('#payment_method_other').on('change', function() {
// Show other payment button and options.
console.log('Other option checked : ' + $(this).prop('checked'));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="radio" name="payment_method" id="payment_method_other" value="Online-Others">
<input type="radio" name="payment_method" id="payment_method_cash" value="Cash">
<input type="radio" name="payment_method" id="payment_method_wallet" value="wallet">
<input type="radio" name="payment_method" id="payment_method_online" value="online">
You can remove id attribute and can use value attribute.
html
<input type="radio" name="payment_method" value="Online-Others">
<input type="radio" name="payment_method" value="Cash">
<input type="radio" name="payment_method" value="wallet">
<input type="radio" name="payment_method" value="online">
jquery code will be like
//if you want to show only Cash radio button
$(document).ready(function() {
$("input[value!='Cash']").css('display','none');
});
Alternately if you want to checked one radio button out of four use below jquery.
//if you want to checked Cash radio button out of four use below
$(document).ready(function() {
$("input[value='Cash']").attr('checked','true');
});
Hope it will help.
