This article briefly explains how to use JS to test the opening response speed of the target website. Unexpectedly, JS can also test the website response speed, so let us take a lookJSScript source code!

When I have nothing to do, I wrote a simple little thing using JS to test the opening speed of directory websites. Note that this is only the speed of opening directory websites locally. It does not mean that other users open the directory website at the same speed. In fact, It can also be used to test local network speed

<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>test</title>
</head>

<body bgcolor="transparent" style="color:#FFFFFF;">
<style type="text/css">
input{font-size:12px;padding:0 5px;line-height:21px; font-family:tahoma;border:1px solid #ccc;height:21px;}                        </style>
<script language="javascript">
tim=1
setInterval("tim++",100)
b=1
var autourl = new Array();
autourl[1] = "www.qq.com";
autourl[2] = "www.jb51.net";
autourl[3] = "www.baidu.com";
autourl[4] = "www.sina.com";

function butt(){
document.write("<form name=autof style=&#39;padding:0px; margin:0px;&#39;>")
for (var i = 1; i < autourl.length; i++) document.write("<input type=text name=txt" + i + " size=25 style=&#39;color:#999;&#39; value=测试中…> =》<input type=text name=url" + i + " size=40> =》<input type=button value=GO onclick=window.open(this.form.url" + i + ".value)><br>")
document.write("<input onclick=&#39;window.location.reload()&#39; type=submit value=&#39;刷新&#39; style=&#39;margin-top:10px&#39;></form>")
}
butt()
function auto(url){
document.forms[0]["url"+b].value=url
if(tim>200)
{document.forms[0]["txt"+b].value="网址"+b+"链接超时"}
else
{ document.forms[0]["txt" + b].value = "网址" + b + ": 访问速度" + tim * 10 + "ms" }
b++
}
function run(){for(var i=1;i<autourl.length;i++)document.write("<img  src="/static/imghwm/default1.png"  data-src="+autourl[i]+"  class="lazy"  /"+Math.random()+"    style="max-width:90%"+autourl[i]+"&#39;) style=&#39;display:none&#39; alt="Use JS to test the opening response speed of the target website_javascript skills" >")}
run()
</script>
</body>
</html>

The network environment of each computer is very complex, so the value obtained by this script For reference only.
