Try something like this:

$('body').bind('click', function(e) {
  if (e.target.nodeName != TEXTAREA) {
    // do something
  }
});

No need for the unbind.

However I have a problem where I bind a click function to the entire document but then want to unbind for a specific element in this case a textarea so that clicks inside the textarea do not trigger the anonymous function. Could using namespace s solve the problem.

I have provided the jQuery code I am using to tdo this below:

entire_document.bind('click', function(e)
	{
		jQuery('#textareaid').unbind('click');
                 if (condition)
                 {
                        // do some stuff
                  }
                 else
                  {
                         // do some other stuff
                   }
        entire_document.unbind('click');
	});
