Calling javascript function in asp.net

Question

Ok so this is a snippet of my aspx file, I am trying to call a "hello world" function from the 'test.js' file. This is obviously not working, could someone please recommend me a good way of doing it?

<asp:ScriptManager ID="ScriptManager1" runat="server">
 <Scripts>
 <asp:ScriptReference Path="\App_JavaScript\test.js" />
 </Scripts>
</asp:ScriptManager>
<asp:Button ID="timebutton" runat="server" Text="clickme" OnClick="javascript:getData();" /><br />

Answer 1

OnClientClick

<asp:Button ID="timebutton" runat="server" Text="clickme" OnClientClick="javascript:getData();" />

Use jQuery to assign the function to the click event of the button.

 <script type="text/javascript" src="\App_JavaScript\test.js"></script>
 <script type="text/javascript" src="jQuery.js"></script>
 <script>
 $(document).ready(function(){
 $('#timeButton').click(getData);
 //Use below instead if you are using Master Pages
 //$('#<%= timeButton.ClientID %>').click(getData);
 });
 </script>
<asp:Button ID="timebutton" runat="server" Text="clickme" />

• Yuriy Faktorovich: This will not work. The rendered ID of a server side button is not what you place in the ID field.
• Yuriy Faktorovich: Unless you're talking about .NET 4.0, this will not work. You still need to use the ClientID and not just #timebutton
• Rezler: If the web form is NOT inside a master page, then will the client ID not be the same as the ID specified? It's been a while since I've worked without master pages so I could be mistaken.

If you need a postback to occur you can also use ScriptManager.RegisterClientScriptBlock
