Question

I’d like to fire a custom event in the .text() function in jQuery. It seems like this should be possible but i’m having some trouble figuring out the closures(?). something like:

jQuery.fn.text = function(){
    _text = jQuery.fn.text;
    // fire a custom event/do something
    jQuery.apply(_text,arguments);
}

I think you’ll get an infinite loop (recursive) with that. You need to save a reference to the original text function before overwriting it. You also need to return the result of the call to _text.

_text = jQuery.fn.text;
jQuery.fn.text = function(){
    // fire a custom event/do something
    return _text.apply(this, arguments);
};
