In an asp.net user control I have a button:
<asp:Button ID="addButton" runat="server" Text="Add" OnClientClick="return function()".
I had written jquery code to hide a control( validationsummary) present in the page inside function().
When I wrote "return function()" it behaved as I expected and the control got hidden. While when I wrote only "function"()" the control got hidden but reappeared. What exactly is the difference between the two?
First : the client side runs (
Then - the server side.
The client side code can prevent execution of server side by return true/false.
usually we use it for validation , before submitting to server.
Do this and your server side will ( without hacking) never work :
