Stop reload when using window.location

On click of a开发者_如何学C button I am changing window.location.href, i.e. I am adding one query string parameter. This causes the page to be refreshed (as I am changing window.location.href). I want to know is it possible to stop this page refresh and append the query string in the url?

No. You can change the #hashstring, but changing the query string results in a reload.

Any assignment of new values to the location object from JavaScript will load a new page.

It is possible to change the hash value without refreshing the page but not the query string.

Take a look at this thread, maybe it will help you.

If you append a #hashstring the page will not reload. In addition, if the user hits the back button on the browser it will remove the #hashstring. The #hashstring can be useful for saving state in the URL bar without causing a reload and can be coupled with ajax calls.

It's important to note that the #hashstring will not be sent to the server and is only visible to the web browser. For example: http://example.com/#blah

Will generate a http request that looks like:

GET / HTTP/1.1
Host: example.com

The #blah does not get sent down to the server by the browser.
