jQuery获取元素的渲染高度? [英] jQuery get the rendered height of an element?

问题描述

如何获取元素的渲染高度?

How do you get the rendered height of an element?

假设您有一个<div>元素，其中包含一些内容.内部的内容将扩展<div>的高度.当您未明确设置高度时，如何获得渲染的"高度.显然，我尝试过:

Let's say you have a <div> element with some content inside. This content inside is going to stretch the height of the <div>. How do you get the "rendered" height when you haven't explicitly set the height. Obviously, I tried:

var h = document.getElementById('someDiv').style.height;

执行此操作有技巧吗?如果有帮助，我正在使用jQuery.

Is there a trick for doing this? I am using jQuery if that helps.

推荐答案

应该是

$('#someDiv').height();

使用jQuery.这将以数字的形式检索包装集中的第一个项目的高度.

with jQuery. This retrieves the height of the first item in the wrapped set as a number.

尝试使用

.style.height

仅在您首先设置属性后才能使用.不太有用！

only works if you have set the property in the first place. Not very useful!
