Question

In this jsFiddle

am I trying to pass an argument to a function, but it doesn’t receive the argument or it isn’t executed.

<a href="javascript:addRemove('7249');">Details</a>

JQuery

$(document).ready(function() {

    function addRemove(u) {
    alert(u);
    }

});

Any ideas what’s wrong and how to fix it?

Your code was wrapped in an onload event by jsfiddle (drop-down menu on the left). So if you add a function it won’t be global, but your onclick event calls a global function by the name addRemove.
