如何触发按钮的客户端和服务器端单击事件？

Question

For a requirement, I need to fire both client side and server side click events of a button in ASP.NET. Is that possible? I have tried like the below. But it does not fire client side click event.

[ASPX]

  <asp:Button ID="Button1" runat="server" Text="Disable" OnClick="disable"  CausesValidation="false"  OnClientClick="return click();" />

[Script]

 function click()
 {
        alert("hi")

  }

Answer 1

Yes, it's possible. If the client side Javascript returns true then the server-side method will get called.

For example:

function click()
{
    return confirm("Do you want to continue?");
}

Answer 2

<asp:Button ID="Button1" runat="server" Text="Disable" OnClick="disable"  CausesValidation="false"  OnClientClick="click();" />

function click()
{
   alert("hi");
   this.click();

}

Answer 3

The client side function must be called in your code. Only thing is depending on what it returns the server side function will get called:

   function Click() {
    alert('Hi');
    if (somecondition) {
        return true;
    }
    return false;
}

Also check your server side event handler if it is named correct as you mention in your code "disable". I think this isnt proper name.

Also check if you really need CausesValidation attribute? as this would have been for your validater which might no longer needed as client side function is manually called.
