Use history.pushState() from the HTML 5 History API.

Refer to the HTML5 History API for more details.

Any changes of the loction (either window.location or document.location) will cause a request on that new URL, if you’re not just changing the URL fragment. If you change the URL, you change the URL.

Use server-side URL rewrite techniques like Apache’s mod_rewrite if you don’t like the URLs you are currently using.

You can add anchor tags. I use this on my site so that I can track with Google Analytics what people are visiting on the page.

I just add an anchor tag and then the part of the page I want to track:

var trackCode = "/#" + urlencode($("myDiv").text());
window.location.href = "http://www.piano-chords.net" + trackCode;
pageTracker._trackPageview(trackCode);

Before HTML5 we can use:

parent.location.hash = "hello";

and:

window.location.replace("http:www.example.com");

This method will reload your page, but HTML5 introduced the history.pushState(page, caption, replace_url) that should not reload your page.

parent.location.hash = "hello";

如Vivart和geo1701所述，HTML5 replaceState是答案。但是，并非所有浏览器/版本都支持该功能。 History.js包装了HTML5状态功能，并为HTML4浏览器提供了额外的支持。

注意：如果使用的是HTML5浏览器，则应忽略此答案。如其他答案所示，现在这是可能的。

There is no way to modify the URL in the browser without reloading the page. The URL represents what the last loaded page was. If you change it (document.location) then it will reload the page.

One obvious reason being, you write a site on www.mysite.com that looks like a bank login page. Then you change the browser URL bar to say www.mybank.com. The user will be totally unaware that they are really looking at www.mysite.com.

这是我的解决方案（newUrl是您要用当前URL替换的新URL）：

history.pushState({}, null, newUrl);

如果要更改URL但又不想将条目添加到浏览器历史记录中，则也可以使用HTML5 replaceState：

if (window.history.replaceState) {
   //prevents browser from storing history with each change:
   window.history.replaceState(statedata, title, url);
}

这将“破坏”后退按钮的功能。在某些情况下可能需要这样做，例如图片库（您希望后退按钮返回到图片库索引页面，而不是在浏览的每个图像中都回退），同时为每个图像提供自己的唯一网址。
