Preventing PostBack From javascript

[fadi]

hello again, can anybody tell me how to prevent a postback to the server from havascript. i have a button with a javascript onclick event, if a certain condition is met i dont want to postback to the server, how can i do that

[Robby]

In the function, Return False

I did that and it doesn't work for me. I don't know if it's because the asp:button is in a graphic control?

[Robby]

Do you have client side script running on the Onclick?

hello all, just to mention, i previously solved this problem. u need to return the function besides adding a return false in the function

ex:

function hello()

{

return false;

}

 

in the onclick event of a button put: onclick="return hello();"

just to note, if the control is an asp control, u need to set the onclick event from the server side by placing the line:

button1.attributes.add("onclick","return hello();")

in the page_load event handler as an example
