Question

ajax/html/javascript solution to disableing button for report generation and then reneable

Answer 1

A:

My guess is you just want to prevent double clicking of the button. Why not just use a setTimeout to enable the button a few seconds after its been clicked?

setTimeout() example

so at the start of your desplayPdf function, you might put:

setTimeout("button-b.disabled = false",4000);

This would disable the button for 4 seconds after its clicked, and then enable it.

Yes - i just want to disable double clicking. The setTimeout was an option I considered but I wanted something a bit more accurate since the report generation time can vary. Plus I was just plain curious if it could be done.

I don't think you can do exactly what you want, but both my suggestion and Chibu's should give you workable alternatives.

Answer 2

A:

The best way I can think to accomplish everything that you want, assuming that you're still forcing a download would to be something like this I think:

<html>
<head>
    <script>
        function get_it() {
            document.getElementById('the_button').disabled = true;
            document.getElementById('the_frame').src = "http://www.ca3.uscourts.gov/opinarch/063575p.pdf";
        }
        function enable_button() {
            document.getElementById('the_button').disabled = false; 
        }
    </script>
</head>
<body>
    <iframe id='the_frame' onload='enable_button()'></iframe>
    <button id='the_button' onclick='get_it()'>Get it</button>
</body>
</html>

Basically, you're telling it to send it to the iframe instead of using an AJAX request. Once the pdf is ready, the iframe's onload event will fire, re-enabling the button. You'll probably want to use actual event listeners for this as opposed to the deprecated inline ones that I've used in the example :P
