获取元素的高度减去填充,边距,边框宽度 [英] Get the height of an element minus padding, margin, border widths
问题描述
有没有人知道当没有内联高度声明时,是否可以获得元素的高度(减去垂直填充,边框和边距)?我需要支持IE8及以上版本。
Does anyone know if it's possible to get just the height of an element (minus vertical padding, border, and margin) when there is no inline height declaration? I need to support IE8 and above.
el.style.height
在外部样式表中。
el.offsetHeight
或 el.clientHeight
不工作,因为它们不仅包括元素的高度。我不能只是减去元素的填充等,因为这些值也设置在CSS样式表,而不是内联(因此 el.style.paddingTop
doesn' t工作)。
el.offsetHeight
or el.clientHeight
doesn't work because they include more than just the element's height. And I can't just subtract the element's padding, etc. because those values are also set in a CSS stylesheet, and not inline (and so el.style.paddingTop
doesn't work).
也不能做 window.getComputedStyle(el)
,因为IE8不支持。
Also can't do window.getComputedStyle(el)
because IE8 doesn't support this.
jQuery有一个height()方法,它提供了这个,但是我没有在这个项目中使用jQuery,加上我只是想知道如何做到这一点纯JavaScript。
jQuery has the height() method, which offers this, but I'm not using jQuery in this project, plus I just want to know how to do this in pure JavaScript.
任何人都有什么想法?非常感谢。
Anyone have any thoughts? Much appreciated.
推荐答案
这里:
var style = window.getComputedStyle(document.getElementById("Example"), null);
style.getPropertyValue("height");
上述版本可在现代浏览器中使用。请检查currentStyle for IE浏览器。
The above version will work in modern browsers. Please check currentStyle for IE browsers.
跨浏览器:
try {
el = window.getComputedStyle(document.getElementById('example'), null)
.getPropertyValue('height');
} catch(e) {
el = document.getElementById('example').currentStyle.height;
}
