js获取来路url地址，相当于php的$_SERVER['HTTP_REFERER']。方法：利用js获取来路url地址可以准确地判断网页的真实来路。 目前百度统计，google ads统计，CNZZ统计，都是用的这个方法。防盗链也很简单了，js里判断来路url如果不是本站不显示图片，嘿嘿。
document.referrer
注：js中的referer是referrer不是referer，即：document.referrer，不要写错了，要注意了，呵呵，我也写错过额。
例
| 代码如下 | 复制代码 |

<table width=100% cellpadding=0 cellspacing=0 border=0 > <script language="javascript"> 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 language="javascript"> 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 language="javascript"> 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>

顺便把js获取当前url的方法也说一下，获取当前页面的url，包括协议、域名、文件夹、文件名和完整的查询参数。
window.location.href
解决IE和FF获取Referer在IE中用javascript做跳转，比如用window.location.href = “”; google如果使用document.referrer无法取到浏览器请求的HTTP referrer，因为IE清空了
而其他主流浏览器Firefox和Chrome都会保留referrer，没办法，这意味着IE又要享受“部长级”特殊待遇了：
以下代码可以解决ie的这个问题:
| 代码如下 | 复制代码 |
| //检测如果是ie浏览器，则手动的给增加一个referer if (/MSIE (d+.d+);/.test(navigator.userAgent)){ var referLink = document.createElement('a'); referLink.href = url; document.body.appendChild(referLink); referLink.click(); } else { location.href = url; } |
|
这样的原理就是给IE浏览器的页面偷偷加了个链接，然后自动点这个链接，于是referrer就能保留了
