I have a plain html/css web site submitting a web form to a script (back end code) on another web site that accepts web forms submissions.

The web site with the back end code is very slow. When visitors of my web site click submit button, nothing visually changes for a while and they keep pressing it again and again thinking that the form was not submitted while in fact it was just a slow response time.

I need to prevent people from submitting many identical forms.

I adjusted my form adding a simple JavaScript that changes the value of my submit button from “SUBMIT” to “PLEASE WAIT...” and I also disable the button.

The back end script on the the other web site has some fields validation. If some fields were left empty, a simple alert message pops up telling the user “please enter...” whatever the field they missed. Then it uses history back.

When I do it on a desktop, let’s say in Google Chrome browser, when the back end script returns me back to the same form that is partially filled out to fill out more fields, my SUBMIT button is enabled again and it says (the value is) SUBMIT again.

THE PROBLEM:
when I do the same on iPhone my SUBMIT button doesn’t recover:
- I submit partially filled out form
• the back end script throws an alert message and forwards me back to previous page in history
• I end up on my partially submitted form
• But my SUBMIT button stays grayed out (disabled) and it still says “PLEASE WAIT...” So I cannot click it anymore. Unless I reload the page. But if I reload the page I lose everything what I already put on the form.

SOLUTION NEEDED
I’m looking for the best simplest and most important reliable JavaScript code that would work in every browser on every platform.
I’d like it to do what my code already does - after SUBMIT button is clicked, disable it and change the value (to say something like PLEASE WAIT”. But if the back end script forwards me back to the sane form instead of the confirmation page, my button should be active again and say SUBMIT again.

  i'm sorry i don't understand what do you mean by image. why image? plain text of the code is good enough. i just need it to be as simple as possible and reliable. working reliably on all platforms and browsers. with my problem fixed.
