How to use action attribute of form tag in html?

I am having trouble to put the right attribute in a action on <form> in HTML

I plan to create a DELETE button which on clicking would prompt a alert box for confirmation.

Upon receiving the right input would delete that entry.

URL for deleting the file is given by "deleteFile?ID=$file_name"

Here is what I have developed so far:

<form METHOD="LINK" action="deleteFile?ID=$fileID"
    <input TYPE="submit" VALUE="Delete">
</form>
</td>

Can you please help for prompting for the alert box. I have written the code in JavaScript called COnfirmDelete()

I am not able to put all the pieces together like :

  1. User would click on the button Delete
  2. It prompts for a confirm the action
  3. Delete the particular file
  4. Return to home screen.

Sample
http://jsfiddle.net/Xv2V4/2/
It is better not to have script in html script tags, but JSfiddle won't recognize my functions defined below.

JS 

function ConfirmDelete() {

    /* if you need to check this ID or sth. else. */
    var fileId = document.getElementById("fileId"); 

    var user_confirm = confirm('Really delete this file?');

    /* Check your file ID or whatever you want to check here. */
    return user_confirm;
}

HTML 

<form method="GET" action="deleteFile" onsubmit="return ConfirmDelete();">
    <!-- print $fileID with python to have it in HTML -->
    <input type="hidden" id="fileId" name="ID" value="$fileID" />
    <input type="submit" value="Delete" />
</form>
