jQuery hashchange events
对我而言,它现在看起来是最成熟的解决方案(如果我错了,请纠正我)。 我真的很喜欢这个用浏览器哈希操纵的插件。在某些情况下,它会简化js代码。
For me it looks like most mature solution right now(please correct me if I'm wrong). I really like this plugin for manipulating with browsers hashes. It simplifies js code a lot in some cases.
我真的想开始大量使用它,但我有一个问题。
I really want to start use it extensively but I have a question for you.
相应于源它使用循环并检查散列锚是否每50毫秒更改一次。
Accordingly to the source it uses loop and check whether hash anchor was changed every 50 ms.
性能怎么样?我可以过度使用hashchange吗?它会导致性能显着下降吗?如果是这样的情况呢?
What about performance? Can I overuse hashchange? Can it lead to some significant slowdown in performance? If so in which cases?
推荐答案每隔50ms检查一个简单的字符串属性是一个无穷小的成本,而不是所有否则你正在运行,我不会在这里关注性能。如果你经常改变哈希并且你的回调非常,非常那么处理那个(你回调),但是检查本身是一个非常非常的小成本。
Checking a simple string property every 50ms is an infinitesimal cost compared to probably everything else you're running, I wouldn't be concerned about performance here. If you're changing the hash often and your callback is very, very expensive then deal with that (you callback), but the check itself is a very, very small cost.
另请注意,50ms检查仅适用于没有 window.onhashchange 内置的浏览器在,对于那些它是一个本地事件(和那是最现代的浏览器)。
Also keep in mind that 50ms check is only for browsers that don't have window.onhashchange built-in, for those it's a native event (and that's most modern browsers).
