问题描述
除了循环遍历每个样式属性声明的数组之外,有没有办法获得dom元素所有样式的键/值输出?
Aside from looping through an array that has each style property declared, is there any way to get a key/value output of all styling of a dom element?
我的备用程序通过列出的键迭代:
http://www.w3.org/TR/DOM-Level-2-Style/css.html#CSS-CSSview-getComputedStyle
My fallback is iterating through the keys listed on: http://www.w3.org/TR/DOM-Level-2-Style/css.html#CSS-CSSview-getComputedStyle

有没有办法得到dom元素的所有样式的键/值输出?
is there any way to get a key/value output of all styling of a dom element?
是的,但不要期望对值(单位等)的确切处理是同一个跨浏览器。
Yes, but don't expect the exact handling of values (units etc.) to be the same cross-browser.
var styles= [];
// The DOM Level 2 CSS way
//
if ('getComputedStyle' in window) {
var cs= getComputedStyle(element, '');
if (cs.length!==0)
for (var i= 0; i<cs.length; i++)
styles.push([cs.item(i), cs.getPropertyValue(cs.item(i))]);
// Opera workaround. Opera doesn't support `item`/`length`
// on CSSStyleDeclaration.
//
else
for (var k in cs)
if (cs.hasOwnProperty(k))
styles.push([k, cs[k]]);
// The IE way
//
} else if ('currentStyle' in element) {
var cs= element.currentStyle;
for (var k in cs)
styles.push([k, cs[k]]);
}
