问题
I'm trying to get the path length for the stroke of a SVG text element and I'm getting a "path.getTotalLength is not a function" error in my console. When I look up getTotalLength, I see that it's been depreciated? It looks like it has something to do with the shift from SVG1 to SVG2? Is this correct?
回答1:
It has not been deprecated. In SVG 1.1, getTotalLength() is only available on the <path> element.
In SVG 2, which browsers are still in the process of implementing (so you can't rely on it yet), getTotalLength() is available on all shape elements, but not including text elements.
