Question

I use a plugin for jQuery – ContextMenu. – http://abeautifulsite.net/blog/2008/09/jquery-context-menu-plugin/

I want to do on the button – click event – an event contextMenu cancel.

I tried this code: (This does not work correctly.)

JS

$("#btnUnbind").click(function () {
    $('.icon').unbind('contextMenu');
});

HTML

<ul id="myMenu" class="contextMenu">            
    <li class="delete"><a href="#delete">Delete</a></li>            
</ul>

JS

  $(".icon").contextMenu(
                    { 
                        menu: 'myMenu' 
                    }, 
                    function(action, el, pos) 
                    { 
                        contextMenuWork(action, el, pos); 
                    });

     function contextMenuWork(action, el, pos) {
                switch (action) {
                    case "delete":
                        {
                            break;
                        }
                }
     }

Answer 1

In your 1st and 2nd javascript you select .icon, this doesn’t exist in your HTML example.

Also in the 2nd javascript you forgot to put .icon between quotes:

$(.icon)

should be:

$('.icon')

Also to disable the context menu use the following on the selected jquery object:

.disableContextMenu();

So in your case instead of using unbind use:

$('.icon').disableContextMenu();
