概述

扩展 jQuery 元素集来提供新的方法（通常用来制作插件）。

查看这里 plugins 可以获取更多信息。

参数

objectObjectV1.0

用来扩充 jQuery 对象。

示例

描述:

增加两个插件方法。

jQuery 代码:

jQuery.fn.extend({
  check: function() {
    return this.each(function() { this.checked = true; });
  },
  uncheck: function() {
    return this.each(function() { this.checked = false; });
  }
});

结果:

$("input[type=checkbox]").check();
$("input[type=radio]").uncheck();
