检测网站链接速度的JavaScript代码

2008年7月18日

在网页的相应位置加入以下HTML代码：

<script type="text/javascript"> time = 1; setInterval("time++",100); b = 1; var autourl = new Array(); autourl[1] = "http://www.google.com/"; autourl[2] = "http://www.cctv.com/"; autourl[3] = "http://www.google.cn/"; autourl[4] = "http://www.microsoft.com/"; autourl[5] = "http://www.adobe.com/"; autourl[6] = "http://www.dell.com.cn/"; autourl[7] = "http://localhost/"; autourl[8] = "http://www.intel.com.cn/"; autourl[9] = "http://www.sohu.com/"; autourl[10] = "http://www.sina.com/"; autourl[11] = "http://www.yahoo.com/"; autourl[12] = "http://www.baidu.com/"; autourl[13] = "http://www.shudoo.com/"; autourl[14] = "http://bbs.shudoo.com/"; autourl[15] = "http://www.cnbeta.com/"; autourl[16] = "http://www.news.cn/"; autourl[17] = "http://www.net.cn/"; autourl[18] = "http://www.newhua.com/"; autourl[19] = "http://www.cfan.com.cn/"; autourl[20] = "http://www.cpcfan.com/"; function butt(){ document.write("<form id=autof>"); for(var i = 1;i<autourl.length;i++){ document.write("<input type=text id=txt" + i + " size=10 value=测试中... class=buttonface>--><input type=text id=url" + i + " size=60 class=buttonface><br>"); } document.write("</form>"); } butt(); function auto(url){ document.forms[0]["url" + b].value = url; if(time>200){ document.forms[0]["txt" + b].value = "链接超时"; } else{ document.forms[0]["txt" + b].value = "时间" + time / 10 + "秒"; } b++; } function run(){ for(var i = 1;i<autourl.length;i++){ document.write("<img src=" + autourl[ i ] + "/" + Math.random() + " width=1 height=1 onerror=auto('" + autourl[i] + "')>"); } } run(); </script>

然后运行这个网页就可以看到结果。
