[英]IE forgets an A-Tag's hostname after changing HREF
I set the href
-Attribute of an <a ...>
-Tag dynamically in a project. 我在项目中动态设置了
<a ...>
的href
<a ...>
。 At some other point, I check the <a>
's DOM-Property called hostname
, in order to figure out whether or not it's an internal link. 在其他方面,我检查
<a>
的DOM-Property,称为hostname
,以确定它是否是内部链接。
Basically, this is what happens. 基本上,这就是发生的事情。
<!--HTML-->
<a id="my" href="/my/first/link">MyLink</a>
<div id="log"></div>
And JS is: JS是:
// js
var a = document.getElementById( 'my' ),
log = document.getElementById( 'log' );
log.innerHTML += a.hostname + '<br/>';
a.setAttribute('href',"/my/other/link");
log.innerHTML += a.hostname;
(cf. also this fiddle: http://jsfiddle.net/RurQT/ ) (参见这个小提琴: http : //jsfiddle.net/RurQT/ )
As I set d.href
to a relative path, I expect d.hostname
to be unchanged - so the log
-Div contains the same Hostname twice. 当我将
d.href
设置为相对路径时,我希望d.hostname
保持不变 - 因此log
-Div包含两次相同的主机名。 This is correct in FF and Chrome. 这在FF和Chrome中是正确的。
However, InternetExplorer 7, 8 and 9 all insist that the second time, the hostname is empty. 但是,InternetExplorer 7,8和9都坚持第二次,主机名为空。
I am especially confused, because the first link has been relative all along! 我特别困惑,因为第一个链接一直是相对的! I don't have any
<base href>
set, btw. 我没有任何
<base href>
设置,顺便说一下。
I would greatly appreciate any suggestion how I can make InternetExplorer update the "hostname"-Property of the a
-DOM-Element. 我非常感谢任何建议如何让InternetExplorer更新
a
-DOM-Element的“hostname”属性。
You'll have to stash and re-set it it seems: 你必须隐藏并重新设置它似乎:
var d = document.getElementById( 'my' ),
var h = d.hostname
d.setAttribute('href',"/my/other/link");
d.hostname = h
