SVG-> getBBox失败，但只有一半时间

Question

I'm trying to use the getBBox method to get the width of a text element inside an SVG render, BUT for some odd reason it only works half the time, the other half it fails..

Here's my JS code I'm using for that:

console.log(iElement.find('.yLabel2:eq(2)')[0].getBBox());
var passWidth = numberTitle2.node().getBBox().width;

So half the time it will log [object SVGRect] and set passWidth to the width, that's awesome. BUT the other times it logs [object Exception] , doesn't log the width, and breaks the rest of the JavaScript following it.

Inside the Exception object there's name: "NS_ERROR_FAILURE" and result: 2147500037

Any ideas on how to get this to work smoothly or a better way to get the width of an svg element?

Answer 1

It fails in Firefox if the text is not rendered. Eg it is display:none or you've not attached it to the document.
