获取svg
元素尺寸的正确方法是什么?
http://jsfiddle.net/langdonx/Xkv3X/
Chrome 28:
style x
client 300x100
offset 300x100
IE 10:
stylex
client300x100
offsetundefinedxundefined
FireFox 23:
"style" "x"
"client" "0x0"
"offset" "undefinedxundefined"
在上有width和height属性svg1
,但.width.baseVal.value
仅当我在元素上设置width和height属性时才设置。
小提琴看起来像这样:
的HTML
<svg id="svg1" xmlns="http://www.w3.org/2000/svg" version="1.1">
<circle cx="50" cy="50" r="40" stroke="black" stroke-width="1" fill="red" />
<circle cx="150" cy="50" r="40" stroke="black" stroke-width="1" fill="green" />
<circle cx="250" cy="50" r="40" stroke="black" stroke-width="1" fill="blue" />
</svg>
JS
var svg1 = document.getElementById('svg1');
console.log(svg1);
console.log('style', svg1.style.width + 'x' + svg1.style.height);
console.log('client', svg1.clientWidth + 'x' + svg1.clientHeight);
console.log('offset', svg1.offsetWidth + 'x' + svg1.offsetHeight);
的CSS
#svg1 {
width: 300px;
height: 100px;
}
svg
尽管画了什么,没有办法将其视为HTML元素并获得该元素占用的实际大小吗?jsfiddle.net/Xkv3X/4
