添加一个额外的单词来添加我的所有网址

I need to add extra word in all my blog link.

I am using blogger.

For example.

The Url is : http://wwww.example.com/post1.html then it will automatic change to http://wwww.example.com/post1.html?extraword

means i need to add in all link ?extraword after my original link.

I have referred .htaccess add an extra word to add all my URLs but it about htaccess, but blogger doesn't have htaccess.

so please suggest me a code with javascript, with add some extra word in all my url.
