Preventing Double Orders

The JavaScript code shown in this section prevents an order from being submitted more than once.
The key is that instead of a standard "submit" button (
<input type="submit"...>
), use a regular button (
<input type="button"...>
) that calls the "submit()" function using JavaScript.
The following code goes in the head:
<SCRIPT language="JavaScript"> <!-- var submitted = false; function doSubmit(form) { if (!submitted) { submitted = true; form.submit(); } } // --> </SCRIPT>
And the following code is the generic button and function call:
<INPUT TYPE="BUTTON" VALUE="Click To Accept" NAME="submission" ONCLICK="doSubmit(this.form)">
