ASP.NET and JQuery - Default Button Click

I have an ASP.NET page that is basically a search form. My code for this form looks like this:

<form id="mainForm" runat="server">
  Search For: <asp:TextBox ID="searchTB" runat="server" /> 
  <input id="myButton" runat="server" type="button" value="Go" 
    onclick="disableButton(this);" onserverclick="myButton_Click" />

  <script type="text/javascript">
    function disableButton(b) {
      b.disabled = true;
      b.value = "Searching...";
    }
  </script>
</form>

This code works fine as long as a user manually clicks the button. However, if a user hits the "Enter" key, the search is not performed. My question开发者_高级运维 is, how do I set an HTML button to the default button in an ASP.NET page when client-side scripting is involved?

Thank you!

Have you tried the onkeypress event? Bind it to the same function and it should work.

For enter to work by default, your button needs to be the first one on the page and it should be type="submit" rather than type="button".

You could also try changing your input to a standard asp.net button. If you change your javascript function to return true, the post click of the button should still work. However to bind 2 events to the button you may need to add the client side click in your page load method.

myButton.Attributes.Add("onclick", "return disableButton(this)");
