Improved JavaScript Error Handling

To supress JavaScript error messages, simply place this snippet in the Head section of your Web page:

<SCRIPT language="JavaScript">
function dontshowerrormessages() {return true;}
window.onerror=dontshowerrormessages;
</SCRIPT>
An even better method is to use the following code:
 
<SCRIPT language="JavaScript">
function betterhandler(description,pagename,lineno)
{
 alert(
  'An Error occurred! \n'
  +'\n Description: \t'+description
  +'\n Page Name:      \t'+pagename
  +'\n At Line :       \t'+lineno
 )
 return true
}
window.onerror=betterhandler;
