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();
