How can I interpret an extrenal svg file in two.js

问题

Is there any way I can interpret an external svg file with object tag in two.js? I tried in the way below but..

HTML

<object type="image/svg+xml" data="./svg/mydrawing.svg" id="mysvg"></object>

JS

var mySvg = document.getElementById("mysvg").contentDocument;
var shape = two.interpret(mySvg);
console.log(shape);

//in console:
Uncaught TypeError: Cannot call method 'toLowerCase' of undefined

It's nice if I can import an external .svg file as my svg file is too big to write in HTML as Inline SVG.

Thanks in advance.

It could be that you need to select the svg tag within the contentDocument. For example:

var svgObject = document.getElementsByTagName('object')[0];
svgObject.onload = function(){
      var mySvg = svgObject.contentDocument.getElementsByTagName('svg')[0];
      var two = new Two();
      var shape = two.interpret(mySvg);
      console.log(shape);
};
