I am new to javascript. I got the below error while running the code.

ERROR:
Error 1 'ASP.default_aspx' does not contain a definition for 'alertMsg' and no extension method 'alertMsg' accepting a first argument of type 'ASP.default_aspx' could be found (are you missing a using directive or an assembly reference?)

Look for wherever you have alertMsg. You have it defined somewhere that is not correct.

Solution 1

ASP.NET controls talk to the "code behind", not to the scripting on the aspx page.

Either use a regular HTML text control, or try OnClientClick() event of the Button.
