Question

i am using asp button control to call a javascript function. but it is not working. it is showing an error
i am calling javascript function as:

 <asp:button ID="Button1" runat="server" Text="Button" onclick="rock()" />

the javascript function is as:

function rock() {
   var username = prompt("what is your name?", "please enter your name here");

   if (username) {
       alert("nice to meet you," + username + ".");
    }
}

is there any way to call javascript function on asp button?

Answer 1

onclick links to a server method, you want onclientclick. If you had a simple HTML control which was not a server control, you can use onclick but it has a different meaning when it’s an ASP.net control.

Fixed code:

<asp:button ID="Button1" runat="server" Text="Button" onclientclick="rock()" />
