你可以拥有类似的功能这个：

You can have a function like this:

function updateHash(newHash){
  ...
  oldHash = newHash
}

然后在你的setTimeOut中你需要做

then in your setTimeOut you need to do

function(){
  if(oldHash != currenHash){
    updateHash(currenHash);
  }
}

所以现在你可以手动调用update hash并赢了不会被事件触发。您还可以在updateHash中使用更多参数来执行其他操作。

So now you can call update hash manually and it won't be triggered by the event. You can also have more parameters in updateHash to do other things.
