用于 IE7 的 hashchange polyfill，可以在每个刻度上跟踪多个事件

Question

I need to fire a hash change event more than once per tick.

My current polyfill looks like this.

//If the hashchange event is missing implement it
hashchangeSupported || (function() {

    //save the current hash for reference next cycle
    var lastHash = location.hash;

    //check the hash for changes every tick
    setInterval(function() {

        //if the hash is different since the last tick then
        // fire a hash change event.
        if(lastHash !== location.hash) {
            trigger('hashchange', window);
            lastHash = location.hash;
        }
    }, 1);
});

The problem is that if the hash is updated more than once per tick it still only fires a single hash change event. I'm looking for a way to check for changes more than once per tick.

I know this is asking a lot and I doubt its possible without getters and setters but I'm aware there are better programmers that I on Stack Overflow and I want some second opinions.
