Wkhtmltopdf waits for conditions before printing

Question

We use wkhtmltopdf to convert dynamic html pages to pdf. We need to wait until all ajax requests are complete.

Is it possible to defer printing by condition?

Answer 1

You can use the --window-status option, see this message on the mailing list .

Answer 2

You can try using the -javascript-delay option.

Answer 3

If you can change the javascript code on the web page, add this line of code to your javascript when you are sure that everything is ready to download:

 if (your_condition_is_met_here){ window.status = 'ready_to_print'; } 

Then pass the --window-status ready_to_print flag to wkhtmltopdf. For example:

 wkhtmltopdf --window-status ready_to_print map.html map.pdf
