Duplicate network calls

Post the code of the object you are clicking on, and the event that is firing twice. Usually this is caused by declaring it in the OnClick event, as well as Handles Something.click in the even prodecdure.

You have something outside the example triggering another .click(), check for other handlers that are also triggering a click event on that element.

$('selected').unbind('click').bind('click', function (e) {
  do_something();
});

Strange behaviour which I was experienced also. So for me "return false" did the trick.

$( '#selector' ).on( 'click', function() {
    //code
    return false;
});

 You can also try with different methods,

 $('#id').off().on('click', function() {
        // function body
    });
    $('.class').off().on('click', function() {
        // function body
    });

$('.class').on('click', function () {...your codes...});

$(document).on('click','.class', function () {...your codes...});
