如果获取“当前”域名

host = window.location.host;

url=document.domain;

url = window.location.href;

取得完整url路径: 用以下代码可以完整研证结果:

<table width=100% cellpadding=0 cellspacing=0 border=0 >

<script>

thisURL = document.URL;

thisHREF = document.location.href;

thisSLoc = self.location.href;

thisDLoc = document.location;

strwrite = "<tr><td valign=top>thisURL: </td><td>[" + thisURL + "]</td></tr>"

strwrite += "<tr><td valign=top>thisHREF: </td><td>[" + thisHREF + "]</td></tr>"

strwrite += "<tr><td valign=top>thisSLoc: </td><td>[" + thisSLoc + "]</td></tr>"

strwrite += "<tr><td valign=top>thisDLoc: </td><td>[" + thisDLoc + "]</td></tr>"

document.write( strwrite );

</script>

thisDLoc = document.location; <BR>

thisURL = document.URL; <BR>

thisHREF = document.location.href; <BR>

thisSLoc = self.location.href;<BR>

<script>

thisTLoc = top.location.href;

thisPLoc = parent.document.location;

thisTHost = top.location.hostname;

thisHost = location.hostname;

strwrite = "<tr><td valign=top>thisTLoc: </td><td>[" + thisTLoc + "]</td></tr>"

strwrite += "<tr><td valign=top>thisPLoc: </td><td>[" + thisPLoc + "]</td></tr>"

strwrite += "<tr><td valign=top>thisTHost: </td><td>[" + thisTHost + "]</td></tr>"

strwrite += "<tr><td valign=top>thisHost: </td><td>[" + thisHost + "]</td></tr>"

document.write( strwrite );

</script>

thisTLoc = top.location.href; <BR>

thisPLoc = parent.document.location; <BR>

thisTHost = top.location.hostname; <BR>

thisHost = location.hostname;<BR>

<script>

tmpHPage = thisHREF.split( "/" );

thisHPage = tmpHPage[ tmpHPage.length-1 ];

tmpUPage = thisURL.split( "/" );

thisUPage = tmpUPage[ tmpUPage.length-1 ];

strwrite = "<tr><td valign=top>thisHPage: </td><td>[" + thisHPage + "]</td></tr>"

strwrite += "<tr><td valign=top>thisUPage: </td><td>[" + thisUPage + "]</td></tr>"

document.write( strwrite );

</script><tr><td>

运行如下: thisDLoc = document.location;

thisURL = document.URL;

thisHREF = document.location.href;

thisSLoc = self.location.href;

thisTLoc = top.location.href;

thisPLoc = parent.document.location;

thisTHost = top.location.hostname;

thisHost = location.hostname;
