如何获得g元素的宽度？

Question

I am having some issue with getting width of <g></g> element using jQuery. Using .innerWidth() or width() returns me null. Is it possible to get the <g></g> width using jquery?

I am asking this, because of rendering differences between Chrome and IE. In chrome I simply use:

var box = svg.node().getBBox();
var width = box.width;

But in IE it doesnt work - it returns the widht of 0.

Add Id to element Maybe work

 <svg viewBox="0 0 95 50"
             xmlns="http://www.w3.org/2000/svg">
           <g stroke="green" fill="white" stroke-width="5" id="myGroup">
             <circle cx="25" cy="25" r="15"/>
             <circle cx="40" cy="25" r="15"/>
             <circle cx="55" cy="25" r="15"/>
             <circle cx="70" cy="25" r="15"/>
           </g>
        </svg>
        <script>
        $(document).ready(function(){
          var height =  document.getElementById("myGroup").getBBox().height;
          var width =  document.getElementById("myGroup").getBBox().width;
          alert(" width "+width+" height "+height);
        });
        </script>
