Javascript checking of button not to be pressed second time

[Валерий Заподовников]

Sometimes when you click (fast) twice on create ticket or send a comment, it just sends it two times. Happened many times, last time here: https://trac.ffmpeg.org/ticket/9390#comment:4

Please fix, click on the button should disable that button, that is like 101 of Javascript! 

If fixed, please point out the commit.

Thanks.

The issue was fixed in Trac 1.0.2:

https://trac.edgewall.org/wiki/TracChangeLog#a1.0.2

The relevant entry is:

Multiple forms submits are disallowed (#10138).

See https://trac.edgewall.org/ticket/10138.

There is a problem with your installation. The browser console shows:

9390:73 Uncaught TypeError: $(...).disableSubmit is not a function
    at HTMLDocument.<anonymous> (9390:73)
    at o (jquery.js:2)
    at Object.fireWith (jquery.js:2)
    at Function.ready (jquery.js:2)

    at HTMLDocument.B (jquery.js:2) 

I suspect the static assets were not redeployed after upgrading Trac:
