通过Javascript在外部窗口中打开链接

Posted 2021-02-26

Rather than using target="_blank", which is deprecated by the W3C in Xhtml, you should use rel="external" for links that you want to pop out in a new window. This is the javascript that makes it happen.

function externalLinks() { 
 if (!document.getElementsByTagName) return; 
 var anchors = document.getElementsByTagName("a"); 
 for (var i=0; i<anchors.length; i++) { 
   var anchor = anchors[i]; 
   if (anchor.getAttribute("href") && 
       anchor.getAttribute("rel") == "external") 
     anchor.target = "_blank"; 
 } 
} 
window.onload = externalLinks;
