jQuery Question

How to toggle a CSS3 checkbox with jQuery?

I've been looking at this demo of a CSS3 checkbox:

http://cssdeck.com/labs/css-checkbox-styles

It is possible to toggle this checkbox (the one in the snippet below) with jQuery?

And, additionally, can I retrieve the checkbox state via jQuery?

I've been trying to follow what happens in Firebug when you click on the checkbox and it seems this is applied:

.squaredThree input[type="checkbox"]:checked + label::after {
opacity: 1;
}


I've tried the following without any success:

$("#squaredThree").prop( "checked",true);

$(".squaredThree input[type='checkbox'] + label::after").css( "opacity","1");




/* SQUARED THREE */

.squaredThree {
width: 20px;
margin: 20px auto;
position: relative;
}
.squaredThree label {
cursor: pointer;
position: absolute;
width: 20px;
height: 20px;
top: 0;
border-radius: 4px;
-webkit-box-shadow: inset 0px 1px 1px rgba(0, 0, 0, 0.5), 0px 1px 0px rgba(255, 255, 255, .4);
-moz-box-shadow: inset 0px 1px 1px rgba(0, 0, 0, 0.5), 0px 1px 0px rgba(255, 255, 255, .4);
box-shadow: inset 0px 1px 1px rgba(0, 0, 0, 0.5), 0px 1px 0px rgba(255, 255, 255, .4);
background: -webkit-linear-gradient(top, #222 0%, #45484d 100%);

}
.squaredThree label:after {
-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
filter: alpha(opacity=0);
opacity: 0;
content: '';
position: absolute;

border: 3px solid #fcfff4;
border-top: none;
border-right: none;
-webkit-transform: rotate(-45deg);
-moz-transform: rotate(-45deg);
-o-transform: rotate(-45deg);
-ms-transform: rotate(-45deg);
transform: rotate(-45deg);
}
.squaredThree label:hover::after {
-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=30)";
filter: alpha(opacity=30);
opacity: 0.3;
}
.squaredThree input[type=checkbox]:checked + label:after {
-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=100)";
filter: alpha(opacity=100);
opacity: 1;
}

<!-- Squared THREE -->
<div class="squaredThree">
<input type="checkbox" value="None" id="squaredThree" name="check" />
<label for="squaredThree"></label>
</div>




Answer

Try this

Get State- var state = document.getElementById('squaredThree').checked;

Set to True - document.getElementById('squaredThree').checked = true;

Set to False- document.getElementById('squaredThree').checked = false;
