为Ajax应用程序启用back / fwd键事件 [英] Enabling back/fwd key events for an Ajax Application

问题描述

我有一个适用于AJAX的应用程序。但是我想要有导航功能。为了欺骗网址，我正在更改location.hash，以生成网址。但是，如果我使用back / fwd，只有url更改，但页面不会重新加载。如何重写hstory.back以重新加载页面。

I have an application which works heavily on AJAX. However I want to have navigation functionalities in it. To spoof the url, I am changing the location.hash, to generate URL. But if i use back/fwd, only the url changes, but page wont reload. How can I override the hstory.back to reload the page.

推荐答案

除了持续轮询以实现此行为之外，我不知道任何其他方式。实现可能如下所示：

I don't know of any other way than continuous polling to implement this behaviour. An implementation might look like this:

var lastHash = '';

function pollHash() {
    if(lastHash !== location.hash) {
        lastHash = location.hash;
        // hash has changed, so do stuff:
        alert(lastHash);
    }
}

setInterval(pollHash, 100);
