I'm currently using the following function to 'convert' a relative URL to an absolute one:
我现在使用以下函数将相对URL“转换”为绝对的URL:
function qualifyURL(url) {
var a = document.createElement('a');
a.href = url;
return a.href;
}
This works quite well in most browsers but IE6 insists on returning the relative URL still! It does the same if I use getAttribute('href').
这在大多数浏览器中都很好用,但是IE6仍然坚持返回相对URL !如果我使用getAttribute('href'),它也会这样做。
The only way I've been able to get a qualified URL out of IE6 is to create an img element and query it's 'src' attribute - the problem with this is that it generates a server request; something I want to avoid.
我能从IE6获得合格URL的唯一方法是创建一个img元素并查询它的“src”属性——问题是它生成一个服务器请求;这是我要避免的。
So my question is: Is there any way to get a fully qualified URL in IE6 from a relative one (without a server request)?
所以我的问题是:是否有办法从一个相对的IE6中获得一个完全合格的URL(没有服务器请求)?
Before you recommend a quick regex/string fix I assure you it's not that simple. Base elements + double period relative urls + a tonne of other potential variables really make it hell!
在您推荐一个快速的regex/string修复之前,我向您保证它不是那么简单。基础元素+双周期相对url +一吨其他潜在变量真的让它地狱!
There must be a way to do it without having to create a mammoth of a regex'y solution??
一定有一种方法可以做到这一点,而不需要创建一个庞大的regex'y解决方案?

How strange! IE does, however, understand it when you use innerHTML instead of DOM methods.
多么奇怪!但是,当您使用innerHTML而不是DOM方法时,IE会理解它。
function escapeHTML(s) {
return s.split('&').join('&').split('<').join('<').split('"').join('"');
}
function qualifyURL(url) {
var el= document.createElement('div');
el.innerHTML= 'x';
return el.firstChild.href;
}
A bit ugly, but more concise than Doing It Yourself.
有点丑,但比你自己做更简洁。

As long as the browser implements the
只要浏览器正确实现了
function resolve(url, base_url) {
var doc = document
, old_base = doc.getElementsByTagName('base')[0]
, old_href = old_base && old_base.href
, doc_head = doc.head || doc.getElementsByTagName('head')[0]
, our_base = old_base || doc_head.appendChild(doc.createElement('base'))
, resolver = doc.createElement('a')
, resolved_url
;
our_base.href = base_url || '';
resolver.href = url;
resolved_url = resolver.href; // browser magic at work here
if (old_base) old_base.href = old_href;
else doc_head.removeChild(our_base);
return resolved_url;
}
Here's a jsfiddle where you can experiment with it: http://jsfiddle.net/ecmanaut/RHdnZ/

You can make it work on IE6 just cloning the element:
你可以让它在IE6上工作只是克隆元素:
function qualifyURL(url) {
var a = document.createElement('a');
a.href = url;
return a.cloneNode(false).href;
}
(Tested using IETester on IE6 and IE5.5 modes)

I found on this blog another method that really looks like @bobince solution.
我在这个博客上发现了另一种方法,看起来真的像@bobince解决方案。
function canonicalize(url) {
var div = document.createElement('div');
div.innerHTML = "";
div.firstChild.href = url; // Ensures that the href is properly escaped
div.innerHTML = div.innerHTML; // Run the current innerHTML back through the parser
return div.firstChild.href;
}
I found it a little more elegant, not a big deal.
我觉得它更优雅一点,没什么大不了的。

URI.js seems to solve the issue:
URI。js似乎解决了这个问题:
URI("../foobar.html").absoluteTo("http://example.org/hello/world.html").toString()
See also http://medialize.github.io/URI.js/docs.html#absoluteto
参见http://medialize.github.io/URI.js/docs.html absoluteto
Not testeed with IE6, but maybe helpful for others searching to the general issue.
虽然没有被IE6测试过,但是可能对搜索一般问题的其他人有帮助。

I actually wanted an approach to this that didn't require modifying the original document (not even temporarily) but still used the browser's builtin url parsing and such. Also, I wanted to be able to provide my own base (like ecmanaught's answer). It's rather straightforward, but uses createHTMLDocument (could be replaced with createDocument to be a bit more compatible possibly):
实际上,我希望有一种方法,不需要修改原始文档(甚至是暂时的),但仍然使用浏览器的内置url解析等等。同时,我希望能够提供我自己的基础(如ecmanaught的答案)。它非常简单,但是使用了createHTMLDocument(可以用createDocument替换为createDocument,以便更兼容一些):
function absolutize(base, url) {
d = document.implementation.createHTMLDocument();
b = d.createElement('base');
d.head.appendChild(b);
a = d.createElement('a');
d.body.appendChild(a);
b.href = base;
a.href = url;
return a.href;
}

This solution works in all browsers.
此解决方案适用于所有浏览器。
/**
* Given a filename for a static resource, returns the resource's absolute
* URL. Supports file paths with or without origin/protocol.
*/
function toAbsoluteURL (url) {
// Handle absolute URLs (with protocol-relative prefix)
// Example: //domain.com/file.png
if (url.search(/^\/\//) != -1) {
return window.location.protocol + url
}
// Handle absolute URLs (with explicit origin)
// Example: http://domain.com/file.png
if (url.search(/:\/\//) != -1) {
return url
}
// Handle absolute URLs (without explicit origin)
// Example: /file.png
if (url.search(/^\//) != -1) {
return window.location.origin + url
}
// Handle relative URLs
// Example: file.png
var base = window.location.href.match(/(.*\/)/)[0]
return base + url
However, it doesn't support relative URLs with ".." in them, like "../file.png".
但是,它不支持带有“.. .”的相对url,比如“../file.png”。

This is the function I use to resolve basic relative URLs:
这是我用来解析基本相对url的函数:
function resolveRelative(path, base) {
// Absolute URL
if (path.match(/^[a-z]*:\/\//)) {
return path;
}
// Protocol relative URL
if (path.indexOf("//") === 0) {
return base.replace(/\/\/.*/, path)
}
// Upper directory
if (path.indexOf("../") === 0) {
return resolveRelative(path.slice(3), base.replace(/\/[^\/]*$/, ''));
}
// Relative to the root
if (path.indexOf('/') === 0) {
var match = base.match(/(\w*:\/\/)?[^\/]*\//) || [base];
return match[0] + path.slice(1);
}
//relative to the current directory
return base.replace(/\/[^\/]*$/, "") + '/' + path.replace(/^\.\//, '');
}

It works both in the browser and in node.js or other environments.

I found this blog post that suggests using an image element instead of an anchor:
我发现这篇博文建议使用图像元素而不是锚点:
http://james.padolsey.com/Javascript/getting-a-fully-qualified-url/
http://james.padolsey.com/Javascript/getting-a-fully-qualified-url/
That works to reliably expand a URL, even in IE6. But the problem is that the browsers that I have tested will immediately download the resource upon setting the image src attribute - even if you set the src to null on the next line.
这可以可靠地扩展URL,即使在IE6中也是如此。但是问题是,我测试过的浏览器会在设置image src属性时立即下载资源——即使您在下一行将src设置为null。
I am going to give bobince's solution a go instead.
我打算尝试一下布宾斯的方法。

If url
does not begin with '/'
如果url不以'/'开头
Take the current page's url, chop off everything past the last '/'; then append the relative url.
获取当前页面的url,删除所有超过最后一个'/'的内容;然后追加相关url。
Else if url
begins with '/'
否则,如果url以'/'开头
Take the current page's url and chop off everything to the right of the single '/'; then append the url.
获取当前页面的url并将所有内容删除到单个'/'的右边;然后添加url。
Else if url
starts with # or ?
如果url以#开头,或者?
Take the current page's url and simply append url
获取当前页面的url并简单地附加url
Hope it works for you

If it runs in the browser, this sort of works for me..
如果它在浏览器中运行,这对我来说是可行的。
function resolveURL(url, base){
if(/^https?:/.test(url))return url; // url is absolute
// let's try a simple hack..
var basea=document.createElement('a'), urla=document.createElement('a');
basea.href=base, urla.href=url;
urla.protocol=basea.protocol;// "inherit" the base's protocol and hostname
if(!/^\/\//.test(url))urla.hostname=basea.hostname; //..hostname only if url is not protocol-relative though
if( /^\//.test(url) )return urla.href; // url starts with /, we're done
var urlparts=url.split(/\//); // create arrays for the url and base directory paths
var baseparts=basea.pathname.split(/\//);
if( ! /\/$/.test(base) )baseparts.pop(); // if base has a file name after last /, pop it off
while( urlparts[0]=='..' ){baseparts.pop();urlparts.shift();} // remove .. parts from url and corresponding directory levels from base
urla.pathname=baseparts.join('/')+'/'+urlparts.join('/');
return urla.href;
}
