Question

This is a struts2 question.

Currently, I am using i18n for internationalization in my webapp.
Some of my jsp pages has querystring to store the request information.
For example,

http://myWebsite.com/myWebsite/myPage?productId=12345

When users try to switch language, I rewrite the URL by javascript to

http://myWebsite.com/myWebsite/myPage?request_locale=zh_CN

And it loses the query string.

And my urls are used in different ways:

http://myWebsite.com/myWebsite/myPage
http://myWebsite.com/myWebsite/myPage?productId=12345#myAnchor
http://myWebsite.com/myWebsite/myPage?productId=12345&key2=value2&key3=value3#myAnchor
http://myWebsite.com/myWebsite/myPage?productId=12345&key2=value2&key3=value3&request_locale=zh_CN
http://myWebsite.com/myWebsite/myPage?productId=12345&key2=value2&key3=value3
...

When I try to handle all this differences in javascript, it becomes so complicated.

Is there any good way to retain the querystrings and anchors after switching locale?

Answer 1

When you rewrite the URL using JS, you should do it based on the current URL.

So, if in the browser is showed

http://myWebsite.com/myWebsite/myPage?productId=12345

you should rewrite it as

http://myWebsite.com/myWebsite/myPage?productId=12345&request_locale=zh_CN

For that, using JS you should get the current URL displayed. Take a look to this question for how to.
