I'm coding a javascript scriptlet on which I'm resizing a DOM element. But I need to know if the element was originally sized absolutely or relatively.
我正在编写一个javascript scriptlet，我正在调整DOM元素的大小。但是我需要知道该元素的原始大小是绝对的还是相对的。
Of corse I can read its clientWidth property, but it always returns an absolute integer. How can I know if it was originally specified by a percentage number in a CSS? Is there any CSS property -readable from javascript- containing the original width expression?
我可以读取它的clientWidth属性，但它总是返回一个绝对整数。如何知道它是否最初由CSS中的百分比数字指定？是否有任何CSS属性 - 从javascript-可读 - 包含原始宽度表达式？

If your width value is inside the tag you can use document.getElementById("id").style.width. But if your css is inside a tag style, that's going to make you use jquery for a quick solution or you are going to have to create your own function to extract this value, like this one: How to get an HTML element's style values in javascript?
如果您的宽度值在标记内，则可以使用document.getElementById（“id”）。style.width。但是如果你的css在标签样式中，那么你将使用jquery来快速解决问题，或者你将不得不创建自己的函数来提取这个值，如下所示：如何获取HTML元素的样式值JavaScript的？
