I have lots of javascript alerts throughout my site, I need to style them up using a jquery dialog. Can anyone please tell me how I can setup a default dialog and populate it with the alert text?

A typical alert looks like this:

window.alert("text here");

My current dialog looks like this:

	            autoOpen: false,
	            width: 400,
	            modal: true,
	            closeOnEscape: true,
	            buttons: {
	                "Log Out Now": function () {
	                    window.location.href = o.logoutUrl;
	                "Stay Connected": function () {

Can I set the defaults such as width and close on escape so I don't have to keep adding them for each instance, there are literally hundreds.

Many thanks in advance
