Change ALL links, hrefs,urls with vanilla Javascript & regex

I am trying to replace the url values on the entire page using some vanilla Javascript. I cannot use ANY library/framework. Here's what I have so far which has been placed at the top of each page between the tags:

我试图使用一些vanilla Javascript替换整个页面上的url值。我不能使用任何库/框架。这是我到目前为止已经放置在标签之间每页顶部的内容：

<script type="text/javascript">
function change_url() {
    var str = '';
    str = str.replace(/blog\.domain\.info/g, 'blogtest\.domain\.info');
}
change_url();
</script>

However, this isn't working when the page loads.

但是，当页面加载时，这不起作用。

Basically, I need resource links to go from http://blog.domain.info to http://blogtest.domain.info. Simple task, I know! But the code above isn't working so far.
