j 查询 noob 此处 。
我有一个 jQuery 处理器, 它使用 < code>$( this) 。 我是否有办法从另一个处理器调用此处理器, 并具体说明 < code>$( this) 指的是什么元素?
是的, 您可以使用 < code>. apply 或 < code>. call javarint 函数来进行操作 。
类似 :
handlerName.apply(newScope, [param1, param2]);
或
handlerName.call(newScope, param1, param2);
在那里 newScope 是 this 将提到的 。 handlerName
jQuery 中的 $( this) 只是为了确保 this -- 也就是说,上下文中的当前对象 -- 指指的所有jQuery 方法。但它仍然只是一个对象引用。它听起来就像你想在关闭时把它包起来并传给下一个处理者一样。
以实际代码为例会有帮助。
您也可以使用 < a href=" http://api.jquery.com/jQuery.proxy/" rel="nofollow"\\ code>jQuery.proxy () 方法查看 。
