How do I check/uncheck all checkboxes with a button using jQuery?

I am trying to check/uncheck all checkboxes using jQuery. Now by checking/unchecking the parent checkbox all the child checkboxes are getting selected/deselected also with the text of parent checkbox getting changed to checkall/uncheckall.

Now I want to replace parent checkbox with an input button, and change the text also on the button to checkall/uncheckall. THere is the code, can anyone please tweak the code ?

    $( function() {
        $( '.checkAll' ).live( 'change', function() {
            $( '.cb-element' ).attr( 'checked', $( this ).is( ':che开发者_如何转开发cked' ) ? 'checked' : '' );
            $( this ).next().text( $( this ).is( ':checked' ) ? 'Uncheck All' : 'Check All' );
        });
        $( '.cb-element' ).live( 'change', function() {
            $( '.cb-element' ).length == $( '.cb-element:checked' ).length ? $( '.checkAll' ).attr( 'checked', 'checked' ).next().text( 'Uncheck All' ) : $( '.checkAll' ).attr( 'checked', '' ).next().text( 'Check All' );

        });
    });


   <input type="checkbox" class="checkAll" /> <b>Check All</b>

   <input type="checkbox" class="cb-element" /> Checkbox  1
   <input type="checkbox" class="cb-element" /> Checkbox  2
   <input type="checkbox" class="cb-element" /> Checkbox  3

Try this one :

$(document).ready(function(){
    $('.check:button').toggle(function(){
        $('input:checkbox').attr('checked','checked');
        $(this).val('uncheck all');
    },function(){
        $('input:checkbox').removeAttr('checked');
        $(this).val('check all');        
    })
})

This is the shortest way I've found (needs jQuery1.6+)

HTML:

<input type="checkbox" id="checkAll"/>

JS:

$("#checkAll").change(function () {
    $("input:checkbox").prop('checked', $(this).prop("checked"));
});

I'm using .prop as .attr doesn't work for checkboxes in jQuery 1.6+ unless you've explicitly added a checked attribute to your input tag.

Example-

$("#checkAll").change(function () {
    $("input:checkbox").prop('checked', $(this).prop("checked"));
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<form action="#">
    <p><label><input type="checkbox" id="checkAll"/> Check all</label></p>
    
    <fieldset>
        <legend>Loads of checkboxes</legend>
        <p><label><input type="checkbox" /> Option 1</label></p>
        <p><label><input type="checkbox" /> Option 2</label></p>
        <p><label><input type="checkbox" /> Option 3</label></p>
        <p><label><input type="checkbox" /> Option 4</label></p>
    </fieldset>
</form>

Try This One:

HTML

<input type="checkbox" name="all" id="checkall" />

JavaScript

$('#checkall:checkbox').change(function () {
   if($(this).attr("checked")) $('input:checkbox').attr('checked','checked');
   else $('input:checkbox').removeAttr('checked');
});​

DEMO

Html

<input type="checkbox" name="select_all" id="select_all" class="checkAll" />

Javascript

    $('.checkAll').click(function(){
    if($(this).attr('checked')){
        $('input:checkbox').attr('checked',true);
    }
    else{
        $('input:checkbox').attr('checked',false);
    }
});

---

Try this:

$('.checkAll').on('click', function(e) {
     $('.cb-element').prop('checked', $(e.target).prop('checked'));
});

e is the event generated when you do click, and e.target is the element clicked (.checkAll), so you only have to put the property checked of elements with class .cb-element like that of element with class .checkAll`.

PS: Excuse my bad English!

Solution for toggling checkboxes using a button, compatible with jQuery 1.9+ where toogle-event is no longer available:

$('.check:button').click(function(){
      var checked = !$(this).data('checked');
      $('input:checkbox').prop('checked', checked);
      $(this).val(checked ? 'uncheck all' : 'check all' )
      $(this).data('checked', checked);
});

Below code will work if user select all checkboxs then check all-checkbox will be checked and if user unselect any one checkbox then check all-checkbox will be unchecked.

$("#checkall").change(function () {
    $("input:checkbox").prop('checked', $(this).prop("checked"));
});

$(".cb-element").change(function () {
  if($(".cb-element").length==$(".cb-element:checked").length)
    $("#checkall").prop('checked', true);
  else
    $("#checkall").prop('checked', false);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<input type="checkbox" name="all" id="checkall" />Check All</br>

<input type="checkbox" class="cb-element" /> Checkbox  1</br>
<input type="checkbox" class="cb-element" /> Checkbox  2</br>
<input type="checkbox" class="cb-element" /> Checkbox  3

Agreed with Richard Garside's short answer, but instead of using prop() in $(this).prop("checked") you can use native JS checked property of checkbox like,

$("#checkAll").change(function () {
    $("input:checkbox").prop('checked', this.checked);
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<form action="#">
    <p><label><input type="checkbox" id="checkAll"/> Check all</label></p>
    
    <fieldset>
        <legend>Loads of checkboxes</legend>
        <p><label><input type="checkbox" /> Option 1</label></p>
        <p><label><input type="checkbox" /> Option 2</label></p>
        <p><label><input type="checkbox" /> Option 3</label></p>
        <p><label><input type="checkbox" /> Option 4</label></p>
    </fieldset>
</form>

---

You can try this

    $('.checkAll').on('click',function(){
        $('.checkboxes').prop('checked',$(this).prop("checked"));
    });`

Class .checkAll is a checkbox which controls the bulk action

---

 $(document).on('change', '.check-all', function () {
   if($(this).prop('checked')) {
      $('.check-box').prop('checked', true)
   }else {
      $('.check-box').prop('checked', false);
   }

Best Solution here Check Fiddle

$("#checkAll").change(function () {
    $("input:checkbox.cb-element").prop('checked', $(this).prop("checked"));
});
$(".cb-element").change(function () {
        _tot = $(".cb-element").length                        
        _tot_checked = $(".cb-element:checked").length;

        if(_tot != _tot_checked){
            $("#checkAll").prop('checked',false);
        }
});

<input type="checkbox" id="checkAll"/> ALL

<br />

<input type="checkbox" class="cb-element" /> Checkbox  1
<input type="checkbox" class="cb-element" /> Checkbox  2
<input type="checkbox" class="cb-element" /> Checkbox  3

---

If you want to uncheck all the checkboxes on a page, the easiest way is like this:

$('[type=checkbox]').prop("checked", false);

---

try this

$(".checkAll").click(function() {
    if("checkall" === $(this).val()) {
         $(".cb-element").attr('checked', true);
         $(this).val("uncheckall"); //change button text
    }
    else if("uncheckall" === $(this).val()) {
         $(".cb-element").attr('checked', false);
         $(this).val("checkall"); //change button text
    }
});

---

Shameless self-promotion: there's a jQuery plugin for that.

HTML:

<form action="#" id="myform">
    <div><input type="checkbox" id="checkall"> <label for="checkall"> Check all</label></div>
    <fieldset id="slaves">
        <div><label><input type="checkbox"> Checkbox</label></div>
        <div><label><input type="checkbox"> Checkbox</label></div>
        <div><label><input type="checkbox"> Checkbox</label></div>
        <div><label><input type="checkbox"> Checkbox</label></div>
        <div><label><input type="checkbox"> Checkbox</label></div>
    </fieldset>
</form>​

JS:

$('#checkall').checkAll('#slaves input:checkbox', {
    reportTo: function () {
        var prefix = this.prop('checked') ? 'un' : '';
        this.next().text(prefix + 'check all');
    }
});​

...and you're done.

try this,

<input type="checkbox" class="checkAll" onclick="$('input[type=checkbox][class=cb-element]').attr('checked',this.checked)">

---

You can use this.checked to verify the current state of the checkbox,

$('.checkAll').change(function(){
    var state = this.checked; //checked ? - true else false

    state ? $(':checkbox').prop('checked',true) : $(':checkbox').prop('checked',false);

    //change text
    state ? $(this).next('b').text('Uncheck All') : $(this).next('b').text('Check All')
});

$('.checkAll').change(function(){
    var state = this.checked;
    state? $(':checkbox').prop('checked',true):$(':checkbox').prop('checked',false);
    state? $(this).next('b').text('Uncheck All') :$(this).next('b').text('Check All')
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
 <input type="checkbox" class="checkAll" /> <b>Check All</b>

   <input type="checkbox" class="cb-element" /> Checkbox  1
   <input type="checkbox" class="cb-element" /> Checkbox  2
   <input type="checkbox" class="cb-element" /> Checkbox  3

Try below code to check/uncheck all checkboxes

jQuery(document).ready(function() {
    $("#check_uncheck").change(function() {
        if ($("#check_uncheck:checked").length) {
            $(".checkboxes input:checkbox").prop("checked", true);
        } else {
            $(".checkboxes input:checkbox").prop("checked", false);
        }
    })
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<input type="checkbox" name="check_uncheck" id="check_uncheck" /> Check All/Uncheck All
<br/>
<br/>
<div class="checkboxes">
    <input type="checkbox" name="check" id="check" /> Check Box 1
    <br/>
    <input type="checkbox" name="check" id="check" /> Check Box 2
    <br/>
    <input type="checkbox" name="check" id="check" /> Check Box 3
    <br/>
    <input type="checkbox" name="check" id="check" /> Check Box 4
</div>

Try this Demo Link

There is also another short way to do this, checkout below example. In this example check/uncheck all checkbox is checked or not if checked then all wiil be checked and if not all will be uncheck

$("#check_uncheck").change(function() {
    $(".checkboxes input:checkbox").prop("checked",$(this).is(':checked'));
})

    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
    <input type="checkbox" name="check_uncheck" id="check_uncheck" /> Check All/Uncheck All
    <br/>
    <br/>
    <div class="checkboxes">
        <input type="checkbox" name="check" id="check" /> Check Box 1
        <br/>
        <input type="checkbox" name="check" id="check" /> Check Box 2
        <br/>
        <input type="checkbox" name="check" id="check" /> Check Box 3
        <br/>
        <input type="checkbox" name="check" id="check" /> Check Box 4
    </div>

I know this question is old but, I noticed most people are using a checkbox. The accepted answer uses a button, but cannot work with several buttons (ex. one at top of page one at bottom). So here is a modification that does both.

HTML

<a href="#" class="check-box-machine my-button-style">Check All</a>

jQuery

var ischecked = false;
$(".check-box-machine").click(function(e) {
    e.preventDefault();
    if (ischecked == false) {
        $("input:checkbox").attr("checked","checked");
        $(".check-box-machine").html("Uncheck All");
        ischecked = true;
    } else {
        $("input:checkbox").removeAttr("checked");
        $(".check-box-machine").html("Check All");
        ischecked = false;
    }
});

This will allow you to have as many buttons as you would like with changing text and checkbox values. I included an e.preventDefault() call because this will stop the page from jumping to the top due to the href="#" part.

$(function () {
    $('input#check_all').change(function () {
        $("input[name='input_ids[]']").prop('checked', $(this).prop("checked"));
    });
});

Here is a link, which is used to check and uncheck the parent checkbox and all the child checkboxes are getting selected and deselected.

add this in your code block, or even click of your button

$('input:checkbox').attr('checked',false);

---

$(document).ready( function() {
        // Check All
        $('.checkall').click(function () {          
            $(":checkbox").attr("checked", true);
        });
        // Uncheck All
        $('.uncheckall').click(function () {            
            $(":checkbox").attr("checked", false);
        });
    });

---

removeAttr() no longer works in later versions of jquery. You can use the prop() function.

$(document).ready(function(){
    $('.check:button').click(function(){
        $('input:checkbox').prop('checked',true);
        $(this).val('uncheck all')
    },function(){
        $('input:checkbox').prop('checked', false);
        $(this).val('check all');        
    })
})

Check All with uncheck/check controller if all items is/isnt checked

JS:

e = checkbox id t= checkbox (item) class n= checkbox check all class

function checkAll(e,t,n){jQuery("#"+e).click(function(e){if(this.checked){jQuery("."+t).each(function(){this.checked=true;jQuery("."+n).each(function(){this.checked=true})})}else{jQuery("."+t).each(function(){this.checked=false;jQuery("."+n).each(function(){this.checked=false})})}});jQuery("."+t).click(function(e){var r=jQuery("."+t).length;var i=0;var s=0;jQuery("."+t).each(function(){if(this.checked==true){i++}if(this.checked==false){s++}});if(r==i){jQuery("."+n).each(function(){this.checked=true})}if(i<r){jQuery("."+n).each(function(){this.checked=false})}})}

HTML:

Check ALL controle class : chkall_ctrl

<input type="checkbox"name="chkall" id="chkall_up" class="chkall_ctrl"/>
<br/>
1.<input type="checkbox" value="1" class="chkall" name="chk[]" id="chk1"/><br/>

3.<input type="checkbox" value="3" class="chkall" name="chk[]" id="chk3"/><br/>
<br/>
<input type="checkbox"name="chkall" id="chkall_down" class="chkall_ctrl"/>

<script>
jQuery(document).ready(function($)
{
  checkAll('chkall_up','chkall','chkall_ctrl');
  checkAll('chkall_down','chkall','chkall_ctrl');
