// USAGE:
//	The default button on a page should have class "btnDefault".  Pressing Enter on a textbox
//	or password textbox will trigger the CLICK event of the button with css class "btnDefault".
//	A page can only have one default button.  To force a default button per div/panel, use the
//	clickButton() function instead.

// Javascript / jQuery that is used by most of this project.  If you have a script that's only
//	used on one page, just leave the script in that page for code clarity and maintainability.
//	The only real advantage of having this in a standalone file is the ability to cache it in
//	the user's web browser, and we don't want to cache a lot of data that isn't used often.

// This code runs whenever a page is finished loading.  Anything done here will be truly
//	"global", and will override whatever UI you've coded in the .aspx.vb files.  This has
//	the advantage over normal javascript because .ready() functions can be stacked on top
//	of each other - all .ready() functions will run, regardless of if they're in the basepage,
//	contentpage, or controls.
$(document).ready(function() {
	// Create an event listener instead of scanning the dom for something like .SubmitOnEnter on each keypress.
	// We need this because form.defaultbutton and form.defaultfocus only fire after something has been typed
	// on the form.  The exception is when certain types of asp:validator controls are used, but rather than code a 
	// bunch of exceptions we're just going to blanket this across the ssl project until we have a reason to be more selective.
