I have a BASE tag as below in head section of the page:
<base href="http://localhost/framework">
And a script as below which is relative (of course after base tag):
<script src="/assets/jquery-1.7.1.min.js">
But when I open jQuery from firebug it shows:
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>404 Not Found</title>
</head><body>
Blah Blah Blah....
When I use the below link it's OK though:
<script src="http://localhost/framework/assets/jquery-1.7.1.min.js">
I looked for answer everywhere, but it seems I'm doing my job right! So what is the problem?
/assets/jquery-1.7.1.min.js is not relative but absolute*, the / takes it to the root even with a base tag.
If you remove that /, it should make it relative off the current path, which, when a base tag is present would be http://localhost/framework/.
You will also need to add a trailing / to the end of the href, to indicate that it's a folder.
Full working example:
<!doctype html>
<html>
<head>
<base href="/test/" />
<script src="assets/test.js"></script>
<body>
hi
</body>
</html>
* Actually depending on who you ask, it's still relative since it is relative off the current domain. But I prefer to call this absolute since it's signifying the path is from the root, based on the current domain. Although, I guess technically that makes it relative in the grand scheme of things, and absolute only in terms of the current domain. Whatever.
Try having your base tag like:
<base href="http://localhost/framework/">
and your script tag like:
<script src="assets/jquery-1.7.1.min.js">
