Checkbox to toggle all selection - javascript

I have this javascript code
// Listen for click on toggle checkbox
$('#select-all').click(function(event) {
if(this.checked) {
// Iterate each checkbox
$(':checkbox').each(function() {
this.checked = true;
});
}
});
And I have this
<form action="" method="POST">
Toggle All :
<input type="checkbox" name="select-all" id="select-all" />
then at my table I have multiple checkbox
<input type="checkbox" name="checkbox-1" id="checkbox-1" value="1"> Select
<input type="checkbox" name="checkbox-2" id="checkbox-2" value="2"> Select
<input type="checkbox" name="checkbox-3" id="checkbox-3" value="3"> Select
<input type="checkbox" name="checkbox-4" id="checkbox-4" value="4"> Select
When I click on toggle all, it does not check checkbox-1 to checkbox-4
What went wrong in my javascript code.
Thanks!! I want to actually do a function that will send all the value of checkbox1-4 by post when they are checked on form submit.

Simply do like this.
$('#select-all').click(function(event) {
$(':checkbox').prop("checked", this.checked);
});
You do not need to loop through each checkbox to check all.
Demo
Wrap the code in dom ready if your script is in head tag
$(document).ready(function() {
$('#select-all').click(function(event) {
$(':checkbox').prop("checked", this.checked);
});
});

When checkbox is clicked, how to know the state of the checkboxes

EDIT:
Please read the end part of the post, I know the part that tells which are unchecked needs to be inside the block of code, the issue here is that the first part of the code is not registering the "click". So can't do anything without that.
E2: May take the suggestion of adding a onclick to the boxes, since the code for boxes is generated with JS, I would add it once and all of them will get the function call, but that feels kinda ugly
I have a set of check boxes, and when one is clicked I need to return the values of the unchecked ones.
HTML:
<div id="myCheckboxList">
<input type="checkbox" name="myList" value="1" checked>1
<input type="checkbox" name="myList" value="2" checked>2
<input type="checkbox" name="myList" value="3" checked>3
</div>
JavaScript:
$(function(){
$("input[name=myList]").on("click",function(){
console.log("triggered");
//code here to find which ones are unchecked
});
});
I have tried to also add this in the code
$boxes = $('input[name=myList]:not(:checked)');
$boxes.each(function(){
// Do stuff with for each unchecked box
});
Unfortunatly the "triggered" in not getting output to console, so unsure why it is so, and how would i get an event to happen when the checkboxes are hit
I copied your code directly to a fiddle, and it works fine. You could be missing the jquery library?
EDIT:
Just to be sure, I updated the snippet to generate the inputs, and it still works fine.
$(function() {
var html = '<input type="checkbox" name="myList" value="1" checked>1'
+'<input type="checkbox" name="myList" value="2" checked>2'
+'<input type="checkbox" name="myList" value="3" checked>3';
$("#myCheckboxList").html(html);
$("input[name=myList]").on("click", function() {
console.log("triggered");
//code here to find which ones are unchecked
$boxes = $('input[name=myList]:not(:checked)');
$boxes.each(function() {
console.log($(this).val());
});
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="myCheckboxList">
</div>
Easiest way would be to:
let v = $(this).attr('value');
if(v === 1){ // box 1 selected
Adding this inside your 'click' handler should work.
You need to add your each script inside your click event.
$(function(){
$("input[name=myList]").on("click",function(){
$("input[name=myList]:not(:checked)").each(function() {
console.log($(this).val());
});
});
});
<div id="myCheckboxList">
<input type="checkbox" name="myList" value="1" checked>1
<input type="checkbox" name="myList" value="2" checked>2
<input type="checkbox" name="myList" value="3" checked>3
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Another solution is to add an "onclick" method in your html. This will call a javascript function whenever the checkbox is clicked. That function can contain any logic for your checkboxes.
<input type="checkbox" name="myList" value="1" checked onclick="checkboxChangeEvent();">1
Then you can implement your javascript function to return a list of unchecked boxes or find the input boxes by name and return the alert as in previous answers.
function checkboxChangeEvent(){
$boxes = $('input[name=myList]:not(:checked)');
$boxes.each(function() {
alert($(this).val());
});
}
Try like this:
$(function(){
$("input[name=myList]").on("click",function(){
var uncheck=[];
//console.log("triggered");
//code here to find which ones are unchecked
$boxes = $("input[name=myList]:not(:checked)");
$boxes.each(function(){
// Do stuff with for each unchecked box
uncheck.push($(this).attr('value'))
console.log(uncheck);
});
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="myCheckboxList">
<input type="checkbox" name="myList" value="1" checked>1
<input type="checkbox" name="myList" value="2" checked>2
<input type="checkbox" name="myList" value="3" checked>3
</div>

Javascript - unselect checkboxes, items mutually exclusive

I have a group of check boxes that are all part of one array. What I require is that if the first one is selected (I don't mind), then any of the others are unselected, and vice versa - if one of the bottom three options are selected, then I don't mind needs to be unselected.
The last three options can all be selected at the same time.
This Link is similar to what I am asking to do. Any help would be appreciated
<fieldset class="checkbox">
<legend>Sitter type</legend>
<div id="field_844" class="input-options checkbox-options">
<label for="field_1071_0" class="option-label">
<input type="checkbox" name="field_844[]" id="field_1071_0" value="I don't mind">I don't mind</label>
<label for="field_1072_1" class="option-label">
<input checked="checked" type="checkbox" name="field_844[]" id="field_1072_1" value="Sitter">Sitter</label>
<label for="field_1073_2" class="option-label">
<input type="checkbox" name="field_844[]" id="field_1073_2" value="Nanny">Nanny</label>
<label for="field_1074_3" class="option-label">
<input type="checkbox" name="field_844[]" id="field_1074_3" value="Au Pair">Au Pair</label>
</div>
</fieldset>
The code is exactly the same as the link you provided.
<fieldset class="checkbox">
<legend>Sitter type</legend>
<div id="field_844" class="input-options checkbox-options">
<label for="field_1071_0" class="option-label">
<input type="checkbox" name="field_844[]" id="field_1071_0" value="I don't mind">I don't mind</label>
<label for="field_1072_1" class="option-label">
<input checked="checked" type="checkbox" name="field_844[]" id="field_1072_1" value="Sitter">Sitter</label>
<label for="field_1073_2" class="option-label">
<input type="checkbox" name="field_844[]" id="field_1073_2" value="Nanny">Nanny</label>
<label for="field_1074_3" class="option-label">
<input type="checkbox" name="field_844[]" id="field_1074_3" value="Au Pair">Au Pair</label>
</div>
</fieldset>
And then:
// We cache all the inputs except `#field_1071_0` with `:not` pseudo-class
var $target = $('input:not(#field_1071_0)');
$('#field_1071_0').on('change', function () {
// if 'i don't mind' is selected.
if (this.checked) {
// remove the 'checked' attribute from the rest checkbox inputs.
$target.prop('checked', false);
}
});
$target.on('change', function () {
// if one of the bottom three options are selected
if (this.checked) {
// then I don't mind needs to be unselected
$('#field_1071_0').prop('checked', false);
}
});

I cannot remember an in-house feature of JavaScript or jQuery that makes it possible to solve your problem. So, you have to solve it by your own.
You can add a data attribute to your checkboxes where you list all the checkboxes (as an id) which cannot be selected at the same time with the current checkbox, e.g.:
<input type="checkbox" name="field_844[]" id="field_1071_0" value="I don't mind" data-exclude="['field_1072_1','field_1072_2','field_1072_3']" />
<input checked="checked" type="checkbox" name="field_844[]" id="field_1072_1" value="Sitter" data-exclude="['field_1071_0']" />
...
Then, you add, for example, an onchange event to each of the checkboxes. This event checks whether the checkbox has changed to checked or to unchecked. If it has changed to checked, you have to uncheck all checkboxes within the list:
document.getElementById("field_1071_0").onchange= function(e) {
if (this.checked) {
this.dataset.exclude.forEach(function (exc) {
document.getElementById(exc).checked = false;
});
}
};
Or, with jQuery:
$("#field_1071_0").change(function (e) {
if ($(this).prop("checked")) {
$(this).data('exclude').forEach(function (exc) {
$("#" + exc).prop("checked", false);
});
}
});
The good thing is: You can apply this function to each checkbox you want, e.g.:
$("input:checkbox").change(function (e) {
if ($(this).prop("checked")) {
$(this).data('exclude').forEach(function (exc) {
$("#" + exc).prop("checked", false);
});
}
});
Now, each checkbox has the desired behaviour. So, this solution is a general way to solve it.
Comment: If you do not have access to the HTML code, i.e., to the input fields to add some information like the data-attribute, you can add those information via jQuery/JavaScript too:
$("#field_1071_0").data("exclude", ['field_1072_1','field_1072_2','field_1072_3']);
$("#field_1072_1").data("exclude", ['field_1071_0']);
...
jquery prop method can be used to pragmatically check or unchecked a check box. is can be use to evaluate if a condition is true or false.
Hope this snippet will be useful
// if first check box is selected , then checkedremaining three
$("#field_1071_0").on('change', function() {
//$(this) is the check box with id field_1071_0
// checking if first checkbox is checked
if ($(this).is(":checked")) {
//opt2 is a common class for rest of the check boxes
// it will uncheck all other checkbox
$(".opt2").prop('checked', false)
}
})
//unchecking first checkbox when any of the rest check box is checked
$(".opt2").on('change', function() {
if ($(this).is(":checked")) {
$("#field_1071_0").prop('checked', false)
}
})
<!--Adding a class `opt2` to the last three checkboxes-->
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<fieldset class="checkbox">
<legend>Sitter type</legend>
<div id="field_844" class="input-options checkbox-options">
<label for="field_1071_0" class="option-label">
<input type="checkbox" name="field_844[]" id="field_1071_0" value="I don't mind">I don't mind</label>
<label for="field_1072_1" class="option-label">
<input checked="checked" type="checkbox" class="opt2" name="field_844[]" id="field_1072_1" value="Sitter">Sitter</label>
<label for="field_1073_2" class="option-label">
<input type="checkbox" name="field_844[]" class="opt2" id="field_1073_2" value="Nanny">Nanny</label>
<label for="field_1074_3" class="option-label">
<input type="checkbox" name="field_844[]" id="field_1074_3" value="Au Pair" class="opt2">Au Pair</label>

Cannot deselect radio button?

I have been attempting to allow radio buttons to be deselected using jQuery, but I am running into issues with the prop function. When this code runs, my conditional ($(e.currentTarget).prop('checked')) always evaluates to true.
Here is a fiddle which demonstrates my issue: Jsfiddle
FYI: I am using jQuery 1.8.2, and I cannot update it because it is a legacy project with many dependencies. Also, I MUST use radio buttons per the client's request.
Javascript:
$("input[name=optionMedia]").click(function(e) {
if ($(e.currentTarget).prop('checked')) {
$(e.currentTarget).prop('checked', false);
}
});
Html:
<input class="bigSizeInput" type="radio" id="audioVideo" name="optionMedia" value="1"/>
<input class="bigSizeInput" type="radio" id="showReel" name="optionMedia" value="2" />
You can do it like this
$('input.bigSizeInput').mouseup(function() {
if ($(this).is(':checked')) {
setTimeout(function() {
$('input.bigSizeInput:checked').prop('checked', false);
}, 1)
}
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input class="bigSizeInput" type="radio" id="audioVideo" name="optionMedia" value="1" />
<input class="bigSizeInput" type="radio" id="showReel" name="optionMedia" value="2" />
This is because checked is a property. If its there it is true, if its not it is not true. Hence you either should switch to a checkbox or use
$("..").removeProp('checked')
Using checkbox to check/uncheck is better than radio button. But if you want to use radio button, you need to check if radio is checked, copy it using and remove checked attribute of copied element and then insert it after target radio. At the end remove original radio.
$(document).on("mousedown", "input[name=optionMedia]", function(e) {
if (this.checked)
$(this).clone().prop('checked', false).insertAfter(this).end().remove();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<input class="bigSizeInput" type="radio" id="audioVideo" name="optionMedia" value="1"/>
<input class="bigSizeInput" type="radio" id="showReel" name="optionMedia" value="2" />

Checkbox acting like radio button | Using icheck.js

I have created three checkboxes as follows:
<input type="checkbox" name="upgrade">
<input type="checkbox" name="upgrade">
<input type="checkbox" name="upgrade">
I want these checkboxes to act like radio buttons and using the following jQuery, I am nearly achieving this. I am also using the icheck.js library, so I am doing the jQuery code like this:
$('input[type="checkbox"]').on('ifChanged', function() {
$('input[name="' + this.name + '"]').not(this).iCheck('uncheck');
});
However this is only working with the first change, as soon as I click the third time it doesn't work any longer. Can anyone tell me what I am doing wrong ?
I can not use Icheck plugin but I did with standart checkbox.
$('input[type="checkbox"]').click( function(){
if( $(this).is(':checked') ){
$('input[type="checkbox"]').prop('checked',false);
$(this).prop('checked',true);
}
else {
$(this).prop('checked',true);
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="checkbox" name="upgrade" checked>
<input type="checkbox" name="upgrade">
<input type="checkbox" name="upgrade">
Base on a previous answer, there's no reason for the if statement inside.. this solution will remove all checked, then check the appropriate selection right after.
HTML:
<input type="checkbox" name="upgrade">
<input type="checkbox" name="upgrade">
<input type="checkbox" name="upgrade">
JS:
$('input[type="checkbox"]').click( function(){
$('input[type="checkbox"]').prop('checked',false);
$(this).prop('checked',true);
});

using jquery check the corresponding checkbox

New to jquery question...
Using jQuery, depending on the radio button clicked I would like jQuery auto 'check' the corresponding checkbox.
<input type="radio" value="#ID#" name="#ID#1"
onclick="return tickSession(this);"/>
<input type="checkbox" value="#ID#" id="#ID#"
name="sessionsThatNeedBookingOnto" class="#ID#1"/>
<input type="radio" value="#ID#" name="#ID#1"
onclick="return tickSession(this);"/>
<input type="checkbox" value="#ID#" id="#ID#"
name="sessionsThatNeedBookingOnto" class="#ID#1"/>
<input type="radio" value="#ID#" name="#ID#2"
onclick="return tickSession(this);"/>
<input type="checkbox" value="#ID#" id="#ID#"
name="sessionsThatNeedBookingOnto" class="#ID#2"/>
This is what I have tried but my understanding is a little off...
<script>
function tickSession(elementHere){
alert($(elementHere).val());
$(elementHere).attr('id').attr("checked", "true");
$($(elementHere).val()).attr('checked','checked')
}
</script>
<script>
$(document).ready(function(){
$('input:radio').click(function(){
$(this).next('checkbox').attr('checked',true);
});
});
</script>
Let's rework your checkboxes/radios:
<input type="radio" value="#ID#" name="rd1" class='rd-session-control'/>
<input type="checkbox" value="#ID#" id="for-rd1"
name="sessionsThatNeedBookingOnto" class="#ID#1"/>
Now:
$(function() {
$('.rd-session-control').click(function() {
var checkbox = $('#for-' + $(this).attr('id'));
if (checkbox.is(':checked'))
checkbox.removeAttr('checked');
else
checkbox.attr('checked', 'checked');
});
});
What this does is:
Allow you to set all of the click handlers for the radios at once using a class rd-session-control.
The ID attribute for the checkboxes is sane and easily calculated relative to the radio that controls them.
Uses the :checked selector to test if the checkbox is active or not.
