How to uncheck checkbox using jQuery Uniform library

Question

A simpler solution is to do this rather than using uniform:

$('#check1').prop('checked', true); // will check the checkbox with id check1
$('#check1').prop('checked', false); // will uncheck the checkbox with id check1

This will not trigger any click action defined.

You can also use:

$('#check1').click(); // 

This will toggle the check/uncheck for the checkbox but this will also trigger any click action you have defined. So be careful.

EDIT: jQuery 1.6+ uses prop() not attr() for checkboxes checked value

Looking at their docs, they have a $.uniform.update feature to refresh a "uniformed" element.

Example: http://jsfiddle.net/r87NH/4/

$("input:checkbox").uniform();

$("body").on("click", "#check1", function () {
    var two = $("#check2").attr("checked", this.checked);
    $.uniform.update(two);
});

$("#chkBox").attr('checked', false); 

This worked for me, this will uncheck the check box. In the same way we can use

$("#chkBox").attr('checked', true); 

to check the checkbox.

If you are using uniform 1.5 then use this simple trick to add or remove attribute of check
Just add value="check" in your checkbox's input field.
Add this code in uniform.js > function doCheckbox(elem){ > .click(function(){

if ( $(elem+':checked').val() == 'check' ) {
    $(elem).attr('checked','checked');           
}
else {
    $(elem).removeAttr('checked');
}   

if you not want to add value="check" in your input box because in some cases you add two checkboxes so use this

if ($(elem).is(':checked')) {
 $(elem).attr('checked','checked');
}    
else
{    
 $(elem).removeAttr('checked');
}

If you are using uniform 2.0 then use this simple trick to add or remove attribute of check
in this classUpdateChecked($tag, $el, options) { function change

if ($el.prop) {
    // jQuery 1.6+
    $el.prop(c, isChecked);
}

To

if ($el.prop) {
    // jQuery 1.6+
    $el.prop(c, isChecked);
    if (isChecked) {
        $el.attr(c, c);
    } else {
        $el.removeAttr(c);
    }

}
