exupero commented 5 years ago

What does document.getElementById("target") return? It sounds like its tagName is not "svg" and it has no "getBBox" method.

falali009 commented 5 years ago

this target is must be svg ‘s id ？

exupero commented 5 years ago

It must be the ID of either the SVG node or one of its children. If you're trying to export HTML, take a look at canvg and see if it will do what you want.
