Hello!

WeasyPrint doesn't support JavaScript at all, and there's no plan to support it in the future.

You'll find more in #23 and #454 about how to execute JS or Python code before rendering the result with WeasyPrint.

Workaround to do that?

Workaround to do that?

Yes, as I said in the previous comment, you'll find

• a workaround in Javascript generated content #454 using PhantomJS to generate a DOM tree that is given to WeasyPrint,
• a workaround in Implement target-counter to create table of contents #23 using Python to preprocess your HTML file before giving it to WeasyPrint.

Thank you.

would the DOM contain a canvas js generated content like for chart.js? I doubt. @Javedgouri did you manage to make this work or did you use something else? Like a python charting library to generate images?

i have used python library to generate the graph in svg and that svg i have rendered.

@Javedgouri Can you share the way you generated svg using some python library you mentioned

In case you need to include Chart.js charts, you can generate an image of the chart with QuickChart and then include the result in the PDF
