<snip> In IE5 (which is what Id been developing with) the code caused no problems, but in IE6 clicking the submit button would cause a natural submit to occur AND my javascripts submit() would also work, resulting in a second request swiftly following the first (and generally resulting in a error). Sometimes the first request would get processed second and the page worked, other times the second one would get processed second and so the error was displayed. We had to tell the users to 'keey trying' until I had a chance to fix the problem! </snip>
I prevent double submits by using a timer. On the first submit, the timer is reset to prevent secondary submit attempts. To assist this, the submit button is grayed out (disabled). If the page hasn't gone through in 30 seconds, the grayed out button is enabled for the user try again. Some example code follows: <form name="someForm" action="http://www.someUnknownWebSite.com"; onsubmit="return submitTimer(this);"> Example text <input type="text" name="example" value="extext"> <input type="submit" name="mysubmitbutton" value="Submit Form"> </form> <script language="javascript"> // <!-- var submitTime = new Date(0); // initialize at page load function submitTimer(someForm) { var result = false; var now = new Date(); var difference = now - submitTime; // Has at least 30 seconds passed since the submit // this always works the first time because we back-dated // the first submitTimer. if ( difference > 30000 ) { // Gray out the submit button someForm.mysubmitbutton.disabled = true; // Reset the above grayed-out submit button // after 30 seconds in case the user must // try submitting again due to no server response setTimeout("enableButton(document.someForm.mysubmitbutton);",30000); // Reset the timer to prevent double submits submitTime = new Date(); result = true; }; return result; } function enableButton(btn) { btn.disabled = false; }; // --> </script> Note: not all browsers support the disabled property so it won't gray out on all browsers, but the Date functions I use should still prevent multiple submits. Feel free to add an alert("Please wait until 30 seconds has passed to try again.") if that's your preference.
