我一直试图用getBBox（）获取svg：clipPath元素的高度和宽度。它似乎在firefox中不起作用，除非正确呈现svg元素显示。我还尝试将可见性设置为隐藏各种svg元素。不幸的是，没有运气。我想知道更改DOM元素在firefox中不会抛出NS_ERROR_FAILURE的显示。
//doesn't work with firefox
//console.log(document.getElementById("clipPathBounds").getBBox());.clip-svg {
position: absolute;
clip-path: url(#svgPath);
height: 600px;
width:600px;
} <svg>
<defs>
<clipPath id="svgPath">
<use id="clipPathBounds" xlink:href="#spath" overflow="hidden" />
</clipPath>
