Question

I am trying to have a function done to all links on a page and then have the function undone if a condition is met.

$('a').click(function(){
    //some function
  if ( /*some condition*/ ) {
    $(this).//undo above function
  }
});

Note: I am not trying to use unbind(), I am trying to have the function undo itself. I apologize in advance if this is a bit unclear – please ask me anything you are unsure about. Thanks.

Have you tried:

$('a').click(function(){
    //some function
  if ( /*some condition*/ ) {
    $(this).click(function() { return false; });
  }
});

Edit: There is another way that is fairly common that didn’t really occur to me at first. Since you’re doing this to all of your <a> tags, you can use the delegate and undelegate functions to register the event. In more modern versions of jquery this is done with the .on and .off methods:

$("body").on("click", "a", function() {
    //some function
    if ( /*some condition*/ ) {
        $(this).off("click");
    }
});
