为什么基本标签不适用于相对路径? [英] Why base tag does not work for relative paths?
问题描述
我在页面的 <head> 部分有一个 <base> 标记，如下所示:
I have a <base> tag as below in <head> section of the page:
<base href="http://localhost/framework">
下面是一个相对的脚本(当然在<base>之后):
And a script as below which is relative (of course after <base>):
<script src="/assets/jquery-1.7.1.min.js">
但是当我从 firebug 打开 jQuery 时，它显示:
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....
当我使用下面的链接时没关系:
When I use the below link it's OK though:
<script src="http://localhost/framework/assets/jquery-1.7.1.min.js">
我到处寻找答案，但看来我的工作做得对！那么问题出在哪里?
I looked for an answer everywhere, but it seems I'm doing my job right! So what is the problem?
推荐答案
/assets/jquery-1.7.1.min.js 不是相对的而是绝对的*，/ 即使使用 base 标记也将其带到根目录.
/assets/jquery-1.7.1.min.js is not relative but absolute*, the / takes it to the root even with a base tag.
如果您删除该 /，它应该使其相对于当前路径，当 base 标记存在时，该路径将是 http://本地主机/框架/.
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/.
注意:您还需要在 href 的末尾添加一个尾随 /，以表明它是一个文件夹.
Note: You will also need to add a trailing / to the end of the href, to indicate that it's a folder.
完整的工作示例:
<!doctype html>
<html>
<head>
<base href="/test/" />
<script src="assets/test.js"></script>
<body>
hi
</body>
</html>
* 实际上取决于你问的是谁，它仍然是相对的，因为它与当前域无关.但我更喜欢称它为绝对，因为它表示路径来自根，基于当前域.虽然，我想从技术上讲，这使得它在宏伟的计划中是相对的，而仅就当前领域而言是绝对的.随便.
* 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.
