double clickers prob...

[thompom]

Hi,

have researched the double click submit prob and it seems that the solution is to put

this.disabled=true;

in the onclick event of a button

OR put this in the form tag

onsubmit="this.done.disabled = true;"

have tried both but still can 'double book'

can anyone see why this wont work for me

my submit button

<input name="done" type="image" id="done" src="images/tbot6_01.gif" width="87" height="50" border="0" onclick="this.disabled=true;this.form.a.value='A';return EW_checkMyForm(this.form);">

OR

my form tag

<form action="custaddwork.asp" name="custaddwork" id="custaddwork" method="post" onsubmit="this.done.disabled = true;">

Your best bet by far is to do any double-submission detection server-side. That way, it will also work for those users who have JavaScript disabled.

Hope this helps,

hi dan - thanks for your reply

what is the best way to do server side double click submission?

do you have an example?

am thinking something like timestamping the record, then if the the timestamp is less than 2 secs and the customerid is the same as the last record then dont do it??

surely this takes up a lot of processing power as two more recordsets will have to opened.

any ideas welcome

by the way i have some very enthusiastic clickers!

A timestamp could work... although I'd be mor tempted to deliver a GUID into a hidden form field, and then with any submission, check to make sure that GUID hasn't already been submitted.

If it has, you know you're dealing with a duplicate entry.

You could clear the list down at the end of every day so it would never grow too large.

It might be best to ask in the forum for your server-side technology about dup-checking, as there may already be a standard mechanism in place.

Hope this helps,
Dan
