select中无法使用click的处理 - 嗑瓜子儿gf
今天工作用到了select，想要给option添加click点击事件，可是却没有任何效果，百度了才发现，原来竟然是不支持呀！
众所周知(其实我才知道哎),在IE里, select的option是不支持onclick事件的, 而在FF 和 OPERA 里, option 是支持onclick事件的.
(safari似乎也不支持,不过暂时我还不知道如何解决safari的问题.)
我今天是用onchange来解决的，原谅也是才知道它可以用这个。select状态改变来调用函数。

虽然onchange在某些时刻可以代替 option的click事件, 但是两者并无法做到完全等价. 因为onchange只有在 你点击的option和之前的option不同时才会触发. 当select当前选中的是第一项 而你再次点击第一项时, select是不会被触发的.
下面的代码演示了一种间接实现 option onclick的方法
Copy after login
注意:此方案只适用于 下拉方式的单选select.
