OnClick事件调用js函数和回调函数

Question

I have an external compiled project(asp.net) that we are using in our code. I dont have access to the code behind, just the .aspx pages.

One of the things Im trying to do is to call two functions from the button in the page.

<cc1:ImageButton ID="btnYes" runat="server" OnClick="btnYes_Click" Text="Yes"
                        Width="40px" SkinID="DefaultButton" />

Is there a way I can add a JS function and let the OnClick event call both btnYes_Click and my JS function? something like this? OnClick="btnYes_Click ; myfunction();"

I dont have any access to the code behind page.

Answer 1

Yes there is an event called OnClientClick="JSFunction" add that to your control. if not then add it from codebehind like MyControl.Attributes["onclick"] = "JSFunction";
