[英]How to get absolute path from a relative url with no outside info?
I'm trying to dynamically determine whether I'm on a certain page, and set a style on any link linking to itself (for a navigation menu). 我正在尝试动态确定我是否在某个页面上,并在链接到自身的任何链接上设置样式(对于导航菜单)。
The part that's catching me up is how to determine that the page is the current page. 抓住我的部分是如何确定页面是当前页面。
I know I can get window.location, and compare it to the href of any links, but there tiered folders, some of which have files named the same way, and I can't rely on setting a base server url. 我知道我可以获得window.location,并将其与任何链接的href进行比较,但是有分层文件夹,其中一些文件的命名方式相同,我不能依赖于设置基本服务器URL。
Basically I need the value that you get when you hover your mouse over a link, with all the relativity of the href attribute applied to the current location. 基本上我需要将鼠标悬停在链接上时获得的值,并将href属性的所有相关性应用于当前位置。 I'm not really sure how to do that, though.
不过,我真的不知道该怎么做。
based on drew's answer, i tested this 根据画得的答案,我对此进行了测试
function resolveUrl( url ){
var a = document.createElement('a');
a.href=url; // set string url
url = a.href; // get qualified url
return url;
}
and it seems to work for ie8 and up. 它似乎适用于ie8及以上。 ie7 doesnt resolve anything.
ie7没有解决任何问题。

This one works best cross browser 这个最好的跨浏览器
//Resolve absolute url's from relative ones
function qualifyURL( url ){
var img = document.createElement('img');
img.src = url; // set string url
url = img.src; // get qualified url
img.src = null; // no server request
return url;
}
