Say suppose I have one server control called button on my form. When some one will click on my button then a server side
Function will be called here I want to call a JavaScript function first means before calling server side function
And if my JavaScript function returns true then my form will be post to server otherwise my form will not be posted to
Server. So I want to know how could i prevent to post my form to server by JavaScript. If it is possible then please
Give me the sample code.
