getSVGDocument is returning NULL in Chrome

Question

I'm starting to use SVG and I have the following code:

HTML

<embed id="embed" src="svg.svg" type="image/svg+xml" width="400" height="300" >

<object id="object" data="svg.svg" type="image/svg+xml" width="400" height="300"></object>

Javascript

$(window).load(function (){
//alert("Document loaded, including graphics and embedded documents (like SVG)");

    var svgDoc_embed = document.getElementById("embed").getSVGDocument();
    alert("My svgDoc_embed => " + svgDoc_embed);

    var svgDoc_object = document.getElementById("object").getSVGDocument();
    alert("My svgDoc_object => " + svgDoc_object);  

});

In the FireFox browser works well

My svgDoc_embed => [object SVGDocument]
My svgDoc_object => [object SVGDocument]

but does not work on Chrome browser.

My svgDoc_embed => null
My svgDoc_object => null

I have searched the Internet but can not find anything that works

Any suggestion is welcome

==========================================================================

I try opening the Chrome JS console and type in:

document.getElementById ("object"). GetSVGDocument ();

The result is null.

Also change the code to:

$ ("embed"). load (function () {
svgDoc_embed var = document.getElementById ("embed"). getSVGDocument ();
alert ("My # embed svgDoc_embed =>" + svgDoc_embed);
});

  $ ("object"). load (function () {
  svgDoc_object var = document.getElementById ("object"). getSVGDocument ();
alert ("My # object svgDoc_object =>" + svgDoc_object);
  });

And does not give any results.

Any suggestion is welcome.

Solution

I believe getSVGDocument() is deprecated and didn't work in my copy of FF. Try using firstElementChild instead:

var svg = document.getElementById("object").firstElementChild;

or access the SVG element directly with:

var svg = document.getElementById("foo");

Where "foo" is the value of the id attribute of the root svg element.

<svg id="foo">

When you insert <svg> element inline, it doesn't form separate SVG document. It becomes a part of outer HTML document. When SVG is embedded with <object>, however, it is contained it's own document.

I couldn't find any info on getSVGDocument() being deprecated. Plus, it supported by most of the browsers at the moment.
