Good Morning...

I am using java script in each page to trigger the Enter key press Event inside the textbox. It is working fine. Now i want to place the code in the .js file for global access.

 function EnterKeyPress(id,e) {
       // look for window.event in case event isn't passed in
       if (window.event) { e = window.event; }
       if (e.keyCode == 13 || e.keyCode == 121) {

           window.document.getElementById('<%= ibtnSubmit.ClientID %>').click();
       } 
   }

I dont want to hard code the control id. Can anybody help me please..

You can use your id parameter instead of the ControlID, and when you use this function in your pages, you can pass the ControlID as a parameter:

function EnterKeyPress(id,e) {
  if (window.event) { e = window.event; }
   if (e.keyCode == 13 || e.keyCode == 121) {
     document.getElementById(id).click();
   }
}

You are using ASP .NET, so in your code-behind you can assign the keypress event:

TextBox1.Attributes.Add("onkeypress",
                      string.Format("EnterPressKey('{0}', event);", ibtnSubmit.ClientID));

But wait, that functionality is already done on ASP .NET, you can use ASP:Panel controls to wrap your mon controls, and you can assign a DefaultButton for the panel to indicate which button gets clicked when the Panel control has focus and the user presses the Enter key.

If you're using jQuery you can do it like this:

$("input[id*=ibtnSubmit]").click()

If you want the form to submit when the user presses the Enter key, then you don't need javascript. It will do so automatically. Just put the textbox inside a form element with an action:

<form action="process.php">
  <input type="text">when the enter key is pressed, the form is submitted and sent to process.php</input>
</form>
