Forms JS Library

mu.js (and compressed with packer mup.js 7k)- core stuff mostly for forms

• Most methods take either an id or the object: mu.hideMe(id) or mu.showMe(obj) or mu.hideMe(this)
• getValue/setValue - simply the value for textboxes, textareas, check and radio boxes and select boxes. For other objects, gets/sets the innerText (useful for spans/divs)
• getSelect/setSelect/getSelectText - selectedvalue for select boxes (see also get/setValue below)
• hideMe/showMe/isHidden/toggle - hides and displays (display not visibility)
• addClass/removeClass/hasClass - allows multiple classnames
• readOnly/ readWrite - disabling/enabling fields (disable and readonly if applicable; also applies ReadOnly style)
• each(func) - loop through all fields (input and select, not buttons) and execute a function (passing the object reference). Eg mu.each(mu.readOnly);
• addEvent/ removeEvent/ cleanUp - the standard ones (here a Dustin Diaz version). If addEvent is used, cleanUp is automatically added to the unload event (see comments).
• addLoadEvent - a version of addEvent for windows.load.
• trim - remove leading and trailing spaces

Demonstration uses addLoadEvent (addEvent) to assign onclick events to buttons.
mu.each finds all the input fields and adds an event for onfocus to assign a class to highlight it (addClass- IE only).
