获取网站ico图标（使用google）
<!doctype html> <html> <head> <meta charset="utf-8"> <style type="text/css"> #input { height: 300px; padding: 10px 5px; line-height: 20px; width: 1000px; } #submit { height: 30px; text-align: center; color: #ffffff; line-height: 30px; width: 80px; background-color: blue; margin-top: 20px; } #result { margin-top: 20px; } #result li { height: 40px; line-height: 40px; float: left; margin: 10px 14px; } </style> </head> <body> <textarea id="input" placeholder="输入多个网址以空格间隔"></textarea> <div id="submit">获取icon</div> <ul id="result"> </ul> <script type="text/javascript"> var input = document.getElementById("input"); var submit = document.getElementById("submit"); var result = document.getElementById("result"); var val; function trim(str) { var whitespace = ‘ \n\r\t\f\x0b\xa0\u2000\u2001\u2002\u2003\u2004\u2005\u2006\u2007\u2008\u2009\u200a\u200b\u2028\u2029\u3000‘; for (var i = 0, len = str.length; i < len; i++) { if (whitespace.indexOf(str.charAt(i)) === -1) { str = str.substring(i); break; } } for (i = str.length - 1; i >= 0; i--) { if (whitespace.indexOf(str.charAt(i)) === -1) { str = str.substring(0, i + 1); break; } } return whitespace.indexOf(str.charAt(0)) === -1 ? str : ‘‘; } function getFavIconUrl(url) { var prohost; prohost = url.match(/([^:\/?#]+:\/\/)?([^\/@:]+)/i); prohost = prohost ? prohost : [true, "http://", document.location.hostname]; //补全url if (!prohost[1]) { prohost[1] = "http://"; } //抓取ico return "http://www.google.com/s2/favicons?domain=" + prohost[1] + prohost[2]; } submit.onclick = function() { val = input.value; if (!val) alert("输入为空！"); val = val.split(" "); val.forEach(function(item) { item = trim(item); if (!item) return; result.innerHTML += "<li>" + item + "<img src=‘" + getFavIconUrl(item) + "‘></li>"; }); }; </script> </body> </html>
