Description:

Functions:
	This JS Have so many functions to validate ur webpage.

Watchers:(supports netscape also)
	Watchers are the new concepts, u can add watcher for u r Html controls.,
	that will watch the control, accroding to the condition what u have specified in the watcher.
	for example: if u add the "numbersOnly" watcher to u r Html control like textarea or textbox,
				 This watcher never allow to enter the alphapatic character.
				 
				 Syntax:
				 	maximumLength=50;	
					addWatcher("maxLength",document.frm.ta1,maximumLength,"error text");
					addWatcher("numbersOnly",document.frm.ta1);
				
				 << document.frm.ta1 >> : textarea control;
				
				warning:
		 			must add the watcher at ur last of the page.
