返回值:ArrayjQuery.makeArray(obj)

概述

将类数组对象转换为数组对象。

类数组对象有 length 属性,其成员索引为 0 至 length - 1。实际中此函数在 jQuery 中将自动使用而无需特意转换。

参数

objObjectV1.2

类数组对象。

示例

描述:

过滤数组中小于 0 的元素。

HTML 代码:
<div>First</div><div>Second</div><div>Third</div><div>Fourth</div>
jQuery 代码:
var arr = jQuery.makeArray(document.getElementsByTagName("div"));
arr.reverse(); // 使用数组翻转函数
结果:
Fourth
Third
Second
First
