Question

How does Google append search parameters to url without reloading page?

Does anyone know how they do it? I know about the HASH trick and the webkit pushState function. I don't think they are using either.

Their solution is cross browser compatible, do they use a combination of different methods for each browser?

Answer 1

Google uses the hash-trick. Notice that all the parameters are after

http://www.google.com/#

Edit: If you entered the page with other parameters, the # may be further out in the link.

Answer 2

您可以在哈希符号（ # ）之后添加参数，而无需使用window.location.hash属性重新加载页面。
