Question

I am using jQuery to create custom radio buttons and i have a problem.
When clicking on the label that associated with the radio the click events fires twice, if i click only on the radio itself it’s working fine (well actually it’s not the radio i am clicking but the div that wraps the whole input and label). Here is the code:

The HTML:

 <div id="box">
     <asp:RadioButtonList ID="RadioButtonList1" runat="server">
         <asp:ListItem>RADIO1</asp:ListItem>
         <asp:ListItem>RADIO2</asp:ListItem>
         <asp:ListItem>RADIO3</asp:ListItem>
     </asp:RadioButtonList>
</div>

jQuery:

<script type="text/javascript">
       $(function () {
            $('#box').find('input:radio').each(function (i) {

            var input = $(this);
            // get the associated label using the input's id
            var label = $('label[for=' + input.attr('id') + ']');
            // wrap the input + label in a div
            $('<div class="custom-radio"></div>').insertBefore(input).append(label, input);

            var wrapperDiv = input.parent();

            // find all inputs in this set using the shared name attribute
            var allInputs = $('input[name=' + input.attr('name') + ']');

            // necessary for browsers that don't support the :hover pseudo class on labels
            label.hover(

            function () {
                $(this).addClass('hover');
            }, function () {
                $(this).removeClass('hover checkedHover');
            });

            //bind custom event, trigger it, bind click,focus,blur events
            wrapperDiv.bind('updateState', function () {
                if ($(this)[0].children[1].checked) {
                    allInputs.each(function () {
                        var curDiv = $('div > label[for=' + $(this).attr('id') + ']').parent();
                        curDiv.removeClass('custom-radio-checked');
                        curDiv.addClass('custom-radio');
                    });
                    $(this).toggleClass('custom-radio custom-radio-checked');
                }
                else {
                    $(this).removeClass('custom-radio-checked checkedHover checkedFocus');
                }

            })
            .trigger('updateState')
            .click(function () { console.log('click'); })
            .focus(function () {
                label.addClass('focus');
            }).blur(function () {
                label.removeClass('focus checkedFocus');
            });
        }); 
       });
   </script>

Is there any solution for this behaviour?

Try adding:

evt.stopPropagation();
evt.preventDefault();

to the .bind() or .click(), whichever you’re seeing. Also, add the parameter evt to the function, like function(evt) {...
