Question

I need to edit (using javascript) an SVG document embedded in an html page.

When the SVG is loaded, I can access the dom of the SVG and its elements. But I am not able to know if the SVG dom is ready or not, so I cant’ perform default actions on the SVG when the html page is loaded.

To access the SVG dom, I use this code:

var svg = document.getElementById('chart').getSVGDocument(); 

where ‘chart’ is the id of the embed element.

If I try to access the SVG when the html document is ready, in this way:

jQuery(document).ready( function() { var svg = document.getElementById('chart').getSVGDocument(); ... 

svg is always null. I just need to know when it is not null, so I can start manipulate it. Do you know if there is a way to do it?

You could try polling every so often.

function checkReady() {     var svg = document.getElementById('chart').getSVGDocument();     if (svg == null) {         setTimeout('checkReady()', 300);     } else {         ...     } }
