document.createElement("svg") instanceof SVGElement is false

Question

When I tried the code document.createElement("svg") instanceof SVGElement in chrome it returns false. Why?

Answer 1

Creating an element like <svg> not in any context and out of thin air will create an unknown element. If you want to create an SVG element use:

var a = document.createElementNS("http://www.w3.org/2000/svg", "svg");

Now if you compare:

var result = a instanceof SVGElement;

the result will be true.
