How to select or unselect all checkboxes in JQuery

Question

I have several collapsible check-boxes, and am trying to check/uncheck all the boxes within that section.

HTML

Currently when I click on the main checkbox, it simply opens and closes the collapsible dialog.

<li data-role="collapsible" id="educationlayers">
            <h3>
                <input type="checkbox" name="education" id="education" class="layers"/>
                <label for="education">Education</label>
            </h3>
            <fieldset data-role="controlgroup">
                <input type="checkbox" data-mini="true" name="education" id="daycare" class="layers"/>
                <label for="daycare">Day Care</label>
                <input type="checkbox" data-mini="true" name="education" id="elementary" class="layers"/>
                <label for="elementary">Elementary</label>
                <input type="checkbox" data-mini="true" name="education" id="intermediate" class="layers"/>
                <label for="highschool">High School</label>
                <input type="checkbox" data-mini="true" name="education" id="postsecondary" class="layers"/>
                <label for="postsecondary">Post Secondary School</label>
            </fieldset>
         </li> 
         <li data-role="collapsible" id="emergencylayers">
               <h3>
                    <input type="checkbox" name="emergency" id="emergency" class="layers"/>
                    <label for="emergency">Emergency</label>
                </h3>
                <fieldset data-role="controlgroup">
                    <input type="checkbox" data-mini="true" name="emergency" id="ambulance" class="layers"/>
                    <label for="ambulance">Ambulance Station</label>
                    <input type="checkbox" data-mini="true" name="emergency" id="fire" class="layers"/>
                    <label for="fire">Fire Station</label>
                    <input type="checkbox" data-mini="true" name="emergency" id="hospital" class="layers"/>
                    <label for="hospital">Hospital</label>
                    <input type="checkbox" data-mini="true" name="emergency" id="police" class="layers"/>
                    <label for="police">Police</label>
                </fieldset>
          </li>
          <li data-role="collapsible" id="facilitieslayers">
                 <h3>
                    <input type="checkbox" name="facilities" id="facilities" class="layers"/>
                    <label for="facilities">Facilities</label>
                </h3>
                <fieldset data-role="controlgroup">
                    <input type="checkbox" data-mini="true" name="facilities" id="commerce" class="layers"/>
                    <label for="commerce">Chamber of Commerce</label>
                    <input type="checkbox" data-mini="true" name="facilities" id="cityfacility" class="layers"/>
                    <label for="cityfacility">City Facility</label>
                    <input type="checkbox" data-mini="true" name="facilities" id="cityhall" class="layers"/>
                    <label for="cityhall">City Hall</label>
                    <input type="checkbox" data-mini="true" name="facilities" id="govfacility" class="layers"/>
                    <label for="govfacility">Government Facility</label>
                </fieldset>
          </li>

JQuery

JQuery code that doesn't seem to work.

$(document).ready(function() {
    fixContentHeight();
    $('#education').click(function() {
        $("INPUT[name='education']").attr('checked', $('#education').is(':checked'));
    });
});

Any tips would be helpful!

Answer 1

I think,you want this:

$('h3 :checkbox').change(function() {
    //'$(this).parent().next()' is appropriate 'fieldset' element
    $(this).parent().next().find(':checkbox').prop('checked', $(this).prop('checked'));
});

This should work for all 3 ` education, emergency, facilities .

Answer 2

All the answers on Stack Overflow don't work for me.

The following is the solution I finally found:

You can try $("#radioLabel1").trigger("click"); where radioLabel1 is the id of the radio's label.

My working code:

<script type="text/javascript">

$(document).on('pagecreate', function(evt) {     
$('#checkall_home').click(function(evt) {   //checkall_home is the id of the checkall button
    if(evt.handled !== true) // This will prevent event triggering more then once
    {
        //alert('Clicked');
        if ($("#checkall_home").html()=="Check All"){
            //alert("Checking All");
            $("#checkall_home").html("Uncheck All");
            $("input.cbxGroupHome").prop("checked", false);  //first deselect all of the checkboxes with class name "cbxGroupHome", then simulate clicking on all the labels associated with the checkboxes (i.e. has a for="#id" attribute), which are denoted by the class name "lb_cb_home"
            $(".lb_cb_home").trigger("click");
        }else{
           // alert("unchecking all");
            $("#checkall_home").html("Check All");
            $("input.cbxGroupHome").prop("checked", true);//.checkboxradio("refresh");
            $(".lb_cb_home").trigger("click");
        }
        evt.handled = true;
    }
});
});
</script>


<form method="get" action="">
  <fieldset data-role="controlgroup"><!--Because checkboxes use the label element for the text displayed next to the checkbox form element, we recommend wrapping the checkbox in a fieldset element that has a legend which acts as the title for the question.
   Add the data-role="controlgroup" attribute to the fieldset so it can be styled in a parallel way as text inputs, selects or other form elements.-->
    <!-- <legend><h4>Ingredients</h4>`</legend>-->

 <input id="cb2" type="checkbox" class="cbxGroupHome"/> 
<label class="lb_cb_home" for="cb2">1 cup vegetable oil</label>

<input id="cb3" type="checkbox" class="cbxGroupHome"/>
<label class="lb_cb_home" for="cb3">13 pounds fresh green beans, trimmed</label>

<input id="cb4" type="checkbox" class="cbxGroupHome"/> 
<label class="lb_cb_home" for="cb4">5 tablespoons minced garlic</label>

<input id="cb5" type="checkbox" class="cbxGroupHome"> 
<label class="lb_cb_home" for="cb5">5 tablespoons minced fresh ginger root</label>
</fieldset>
</form>

I understand this question is old but for those looking for a jQuery 2.x and jQuery Mobile 1.4.3 example try this:

Answer 4

I don't about what this function (fixContentHeight();) is doing.

Do this way, it works as expected.

//fixContentHeight();
$('#education').click(function() {
    $("INPUT[name='education']")
        .attr({
            checked: $('#education').is(':checked')
        });
});​

Follow the same fashion for other checkbox sections.

UPDATED:

Refer this same piece of code which I have done some modifications to works for all checkbox sections,

//fixContentHeight();
$('h3 input[type=checkbox]').click(function() {
    $("INPUT[name='"+this.name+"']")
        .attr({
            checked: $(this).is(':checked')
        });
});​

HTML:

Actually on your HTML <UL> tag is missing.

<ul>
    <li data-role="collapsible" id="educationlayers">
        <h3>
            <input type="checkbox" name="education" id="education" class="layers"/>
            <label for="education">Education</label>
        </h3>
        <fieldset data-role="controlgroup">
            <input type="checkbox" data-mini="true" name="education" id="daycare" class="layers"/>
            <label for="daycare">Day Care</label>
            <input type="checkbox" data-mini="true" name="education" id="elementary" class="layers"/>

UPDATED 2:

I have gone through your code and modified it. Finally I got your issue with the checkboxes.

You need to refresh the checkboxradio, to get updated with checked value of all checkboxes.

You need to use:-

$("input[name='"+this.name+"']").checkboxradio("refresh");

JS:

$('h3 input[type=checkbox]').click(function() {
    $("input[name='"+this.name+"']")
        .attr({
            checked: $(this).is(':checked')
        });
    $("input[name='"+this.name+"']").checkboxradio("refresh");
});

Answer 5

$('h3 input[type=checkbox]').click(function() {
        var selected = $(this).attr('id');
        $("INPUT[name="+selected +"]").attr({checked: $(this).is(':checked')});
});

Answer 6

You need to stop the click event from bubbling up to your <li> which is collapsible.

$('h3 input[type=checkbox]').click(function(e) {
    $("INPUT[name='"+this.name+"']")
        .attr({
            checked: $(this).is(':checked')
        });
    e.stopPropagation();  //<--stops the click from bubbling up.
});​

documentation: http://api.jquery.com/event.stopPropagation/

edit: reading more about the collapsible, in theory only click the header should be collapsing the li. check to make sure your <h3> tags are all closed properly and there isn't any stray elements missing closing tags.
