返回值:Integer
height([val|fn])
概述
取得匹配元素当前计算的高度值（px）。
在 jQuery 1.2 以后可以用来获取 window 和 document 的高
参数
valString, Number, FunctionV1.0
设定CSS中 'height' 的值，可以是字符串或者数字，还可以是一个函数，返回要设置的数值。函数接受两个参数，第一个参数是元素在原先集合中的索引位置，第二个参数为原先的高度。
function(index, height)String, Number, FunctionV1.4.1
返回用于设置高度的一个函数。接收元素的索引位置和元素旧的高度值作为参数。
示例
无参数描述:
获取第一段的高
jQuery 代码:
$("p").height();参数val 描述:
把所有段落的高设为 20:
jQuery 代码:
$("p").height(20);参数function(index, height) 描述:
以 10 像素的幅度增加 p 元素的高度
jQuery 代码:
$("button").click(function(){
$("p").height(function(n,c){
return c+10;
});
});
