I have a javascript code in my HTML which generate a graph using chart.js.
but when i generate pdf using HTML, the graph doesn't generate in pdf.

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?
