if you have JavaScript function on your page, put Return False, http://stackoverflow.com/questions/855360/when-and-why-to-return-false-in-javascript — Safi, Jun 27 '11 at 12:35

This is typically caused when a jscript function cannot be resolved. Do you have a reference to the JQuery library containing the jAlert function?

i have that in my Master page. – Nick Kahn Aug 04 '10 at 17:53
@Nisar Khan - Can you confirm that the library is getting loaded using a tool like Firebug? Path is correct? What happens if you change the code to a Javascript alert instead? Does it now work? What does the script block that is being generated look like? A few ideas of things to try. – DaveB Aug 04 '10 at 18:08
my scripts were in "" and i moved those scripts to section now its working. – Nick Kahn Aug 04 '10 at 18:37
