Well you have to rewrite it to use a Promise

[patilharshal16]

yet this bug is not resolved. I have updated html2canvas

[patilharshal16]

html2canvas returns a Promise with the canvas as the value

[galileomd]

the problem seems to be with addHTML not keeping up with html2canvas updates

[miigangls]

Is this already solved @ClaytonWang ?

[Bscheef]

options.onrendered is deprecated

This means html2canvas doesn't use onrendered anymore, therefore this is not a bug. What you have to do now in order to execute code after rendering the canvas is the following:

html2canvas(document.querySelector("#myDiv")).then(canvas => {
    document.body.appendChild(canvas);
    saveImage();     //or whatever you want to execute
});

We are closing this issue, because we will not support any longer fromHTML and addHTML.

Explaination:
We are working on a new html2pdf plugin, which will be based on html2canvas and our context2d plugin. This should lead to more reliable results for your projects. And it will give us the time to focus on the core functionality of pdf-generation because we will not use our energy for writing/supporting/extending 2 html plugins. If you still want to use addHTML or fromHTML you can still use jsPDF 1.4.1.

Best Regards

@arasabbasi when do you think your new plugin will be ready?
