In Chrome, resource isn't loaded when $(document).ready() is triggered. Why?

问题

In FF and IE, the SVG (SVG) document is retrieved when $(document ).ready() is called.

In Chrome, the getSVGDocument returns null instead when $(document ).ready() is called. (Although it seems to find it approx 7ms after, as shown by the setTimeout.)

Why does Chrome not find the loaded <embed> SVGdocument at moment of $(document ).ready(), but FF and IE do?

(I don't want to have to use a setTimeout(7ms) just to wait for Chrome to catch up!!! Because that's... lame.)

The code simple code below shows scenario: RETURNS SVGDocument in FF + IE RETURNS NULL in Chrome (unless the call to getSVG() is delayed by 7ms!!!).

N.B: This code needs to be run on localhost server with Chrome; that is a separate Chrome issue.

    $(document).ready(function () {

        getSVG();                        

        //setTimeout("getSVG()", 7);      // this works, showing that Chrome is NOT "ready"

Try this

$(window).load(function(){
    console.log($('#embedId')[0].getSVGDocument());
});

Another possible solution:

$(function(){
    var a = $('#embedId')[0];

    a.addEventListener("load",function(){

        //do stuff with 'a'

    },false);
});

You should use $(window).load() instead of $(document).ready() to wait for loaded embbeds, iframes and images
