jQuery: execute function upon keydown

[eluser]codex[/eluser]
I'm trying to execute a function upon keydown but I can't get it to work. saveChangesTitle() is a self defined function, but when I try to do it as below I get an error saying saveChangesTitle() is not a function. How do you do this the proper way?

Code:

jQuery('.eip-text').keydown(function(e){
                        if (e.keyCode == 13) {
                            e.saveChangesTitle(this, revert, i, title_id);
                            return false;
                        }
                    });

I'm not familiar with jQuery, but is the type of argument e to your anonymous function a Javascript event? If that's the case, then saveChangesTitle isn't a function defined by Event, and you should probably find a less messy way of including it in your event handler. Here's how I'd do it:

Code:

(function() {
    var saveChangesTitle = function(element, revert, i, title_id) {
        ...
    };
    
    jQuery('.eip-text').keydown(
        function(e) {
            if (e.keyCode == 13) {
                saveChangesTitle(this, revert, i, title_id);
            }
        });
})();

Note, if you really want to define saveChangesTitle on your event object, you'd do it by executing the following code:

Code:

Event.prototype.saveChangesTitle = function(el, revert, i, title_id);

Cool, that will work. Thanks!
