Support for long-running AJAX requests?

[Steve]

I'm trying to render a page that populates a table via a long-running AJAX request.

The page renders, but without the results of the query...I just get an empty table.

I know there's the "--javascript-delay" option, but that presupposes knowledge of how long the query is going to take...

Is there a mechanism by which I could block wkhtmltopdf until all of the AJAX data is loaded?

Thanks,

Steve

In general there is no way to know when ajax is done (it requires
solving the halting problem), however if you control the page loaded,
you can run
"window.status = 'myrandomstring';" in javascript whenever you feel
you are done loading. And then run wkhtmltopdf eq with
"--javascript-delay 100000 --window-status myrandomstring"
This will cause wkhtmltopdf to output the pdf as the document looks
after 100 seconds, or when window.status is set to myrandomstring
whatever comes first.

--window-status is perfect.

Thanks for pointing it out.
