文字
返回值:jQuery
map(callback)
概述
将一组元素转换成其他数组（不论是否是元素数组）
你可以用这个函数来建立一个列表，不论是值、属性还是CSS样式，或者其他特别形式。这都可以用'$.map()'来方便的建立。
参数
callbackFunctionV1.2
给每个元素执行的函数
示例
描述:
把form中的每个input元素的值建立一个列表。
HTML 代码:
<p><b>Values: </b></p> <form> <input type="text" name="name" value="John"/> <input type="text" name="password" value="password"/> <input type="text" name="url" value="http://ejohn.org/"/> </form>
jQuery 代码:
$("p").append( $("input").map(function(){
return $(this).val();
}).get().join(", ") );结果:
[ <p>John, password, http://ejohn.org/</p> ]
