getBBox() returns nothing for rect or path

问题

Please refer below rect code.

<rect id="container_svg_ChartArea" x="146.8" y="20" width="633.2" height="414" fill="White" stroke-width="1" stroke="Gray"></rect>

i tried get the rectangle bounding box value it returns nothing i.e."0" for x=0,y=0,width=0,height=0

$("#container_svg_ChartArea")[0].getBBox()

but when i get the attribute for x/y/width/height it returns some value

$("#container_svg_ChartArea").attr("x") ->value returned.

same for path element as well as rectangle element.

what is going wrong?

Look this example on how to get and manage the bounding box of svg elements

http://www.janvas.com/illustrators_designers_developers/projects/janvas2D_web/examples_EN.php?exampleName=ufo_animation_EN

in general

var svgElement = document.getElementById('the id of your element');
bbox = svgElement.getBBox();

console.log( bbox.x ) ;
console.log( bbox.y ) ;
console.log( bbox.width ) ;   
console.log( bbox.height ) ;
