bind event only once

Question

I have the following code:

function someMethod()
{
  $(obj).click(function {});
}

someMethod is called twice and thus click event is binded

Answer 1

In addition to pna's answer you may wish to think about namespacing your event so you do not go around unbinding all the click events accidentally.

function someMethod() {
    $(obj).unbind('click.namespace').bind('click.namespace', function() { });
}
