[英]find all links that href value begin with "http..", then set target=”_blank“ fo it, use javascript not jquery
怎么了？ document.getElementsByTagName("a[href^='http']");
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width"> <title>JS Bin</title> </head> <body> <a href="http://www.jsbin.com">jsbin</a><br> <a href="http://www.jsbin.com">aaaaaa</a><br> <a href="http://www.jsbin.com" target="_blank">zzzzzzzzzzzz</a><br> <script> window.onload=function(){ var anchors = document.getElementsByTagName("a[href^='http']"); for (var i=0; i<anchors; i++){ anchors[i].setAttribute('target', '_blank'); } } </script> </body> </html>
我認為您正在尋找querySelectorAll函數，而不是getElementsByTagName函數。
