前面一个相关数据监察和控制

品种支付完结外发后,未有三个监督种类,我们很难理解到发布出来的代码在客户机器上试行是还是不是科学,所以要求树立前端代码品质相关的监察系统。

为此大家要求做以下的片段模块:

一、采撷脚本实行错误

JavaScript

function error(msg,url,line){ var REPORT_U奥迪Q5L = "xxxx/cgi"; // 搜聚报告数据的消息 var m =[msg, url, line, navigator.userAgent, +new Date];// 搜集错误消息,爆发错误的台本文件网络地址,客户代理音讯,时间 var url = REPORT_UPRADOL + m.join('||');// 组装错误反馈新闻内容UCRUISERL var img = new Image; img.onload = img.onerror = function(){ img = null; }; img.src = url;// 发送数据到后台cgi } // 监听错误反馈 window.onerror = function(msg,url,line){ error(msg,url,line); }

function error(msg,url,line){
   var REPORT_URL = "xxxx/cgi"; // 收集上报数据的信息
   var m =[msg, url, line, navigator.userAgent, +new Date];// 收集错误信息,发生错误的脚本文件网络地址,用户代理信息,时间
   var url = REPORT_URL + m.join('||');// 组装错误上报信息内容URL
   var img = new Image;
   img.onload = img.onerror = function(){
      img = null;
   };
   img.src = url;// 发送数据到后台cgi
}
// 监听错误上报
window.onerror = function(msg,url,line){
   error(msg,url,line);
}

经过管理后台系统,大家能够看见页面上每一遍错误的新闻,通过那几个音信我们能够便捷定位同临时候消除难题。

二、收集html5 performance信息

performance 蕴含页面加载到推行到位的上上下下生命周期中差别实践步骤的执行时间。performance相关小说点击如下:行使performance API 监测页面品质

算算分化步骤时间绝对于navigationStart的时日差,能够经过相应后台CGI搜集。

JavaScript

function _performance(){ var REPORT_URL = "xxxx/cgi?perf="; var perf = (window.webkitPerformance ? window.webkitPerformance : window.msPerformance ), points = ['navigationStart','unloadEventStart','unloadEventEnd','redirectStart','redirectEnd','fetchStart','domainLookupStart','connectStart','requestStart','responseStart','responseEnd','domLoading','domInteractive','domContentLoadedEventEnd','domComplete','loadEventStart','loadEventEnd']; var timing = pref.timing; perf = perf ? perf : window.performance; if( perf && timing ) { var arr = []; var navigationStart = timing[points[0]]; for(var i=0,l=points.length;i<l;i++){ arr[i] = timing[points[i]] - navigationStart; } var url = REPORT_URL + arr.join("-"); var img = new Image; img.onload = img.onerror = function(){ img=null; } img.src = url; }

function _performance(){
   var REPORT_URL = "xxxx/cgi?perf=";
   var perf = (window.webkitPerformance ? window.webkitPerformance : window.msPerformance ),
      points = ['navigationStart','unloadEventStart','unloadEventEnd','redirectStart','redirectEnd','fetchStart','domainLookupStart','connectStart','requestStart','responseStart','responseEnd','domLoading','domInteractive','domContentLoadedEventEnd','domComplete','loadEventStart','loadEventEnd'];
   var timing = pref.timing;
   perf = perf  ? perf : window.performance;
   if( perf  && timing ) {
      var arr = [];
      var navigationStart = timing[points[0]];
      for(var i=0,l=points.length;i<l;i++){
         arr[i] = timing[points[i]] - navigationStart;
      }
   var url = REPORT_URL + arr.join("-");
   var img = new Image;
   img.onload = img.onerror = function(){
      img=null;
   }
   img.src = url;
}

通过后台接口搜聚和总计,大家得以对页面实行质量有很详细的打听。

三、总结各种页面包车型客车JS和CSS加载时间

在JS或许CSS加载以前打上时间戳,加载之后打上时间戳,何况将数据上报到后台。加载时间反映了页面白屏,可操作的等待时间。

XHTML

<script>var cssLoadStart = +new Date</script> <link rel="stylesheet" href="xxx.css" type="text/css" media="all"> <link rel="stylesheet" href="xxx1.css" type="text/css" media="all"> <link rel="stylesheet" href="xxx2.css" type="text/css" media="all"> <sript> var cssLoadTime = (+new Date) - cssLoadStart; var jsLoadStart = +new Date; </script> <script type="text/javascript" src="xx1.js"></script> <script type="text/javascript" src="xx2.js"></script> <script type="text/javascript" src="xx3.js"></script> <script> var jsLoadTime = (+new Date) - jsLoadStart; var REPORT_URL = 'xxx/cgi?data=' var img = new Image; img.onload = img.onerror = function(){ img = null; }; img.src = REPORT_URL + cssLoadTime + '-' + jsLoadTime; </script>

   var cssLoadTime = (+new Date) - cssLoadStart;
   var jsLoadStart = +new Date;
</script>
<script type="text/javascript" src="xx1.js"></script>
<script type="text/javascript" src="xx2.js"></script>
<script type="text/javascript" src="xx3.js"></script>
<script>
   var jsLoadTime = (+new Date) - jsLoadStart;
   var REPORT_URL = 'xxx/cgi?data='
   var img = new Image;
   img.onload = img.onerror = function(){
      img = null;
   };
   img.src = REPORT_URL + cssLoadTime + '-' + jsLoadTime;
</script>

  var Windowswidth=100
  var numx=5
  function openwindow(thelocation){
  temploc=thelocation
  if
  (!(window.resizeTo&&document.all)&&!(window.resizeTo&&document.getElementById))
  {
    window.open(thelocation)
    return
  }
  windowsize=window.open("","","scrollbars")
  windowsize.moveTo(0,0)
  windowsize.resizeTo(100,100)
  tenumxt()
  }
  function tenumxt(){
  if (Windowsheight>=screen.availHeight-3)
    numx=0
  windowsize.resizeBy(5,numx)
  Windowsheight+=5
  Windowswidth+=5
  if (Windowswidth>=screen.width-5)
  {
    windowsize.location=temploc

  }
  //-->
  </script>
  <p><a href="javascript:openwindow(http://www.3ydesign.com)">进入</a>

17.转移IE地址栏的IELogo

  我们要先做三个16*16的icon(Logo文件),保存为index.ico。把那些Logo文件上传播根目录下并在首页<head></head>之间加上如下代码:

  <link REL = "Shortcut Icon" href="index.ico">

18.在窗口的情景栏展现滚动消息  
(1) 在BODY中投入代码 
<script language="javascript">  
var msg="招待访谈建站能源网,在此处有你会有所收获的!";  
var i=1  
function scroll()  
{  
mess=msg.substring(i,msg.length)+" "+msg.substring(0,i)  
window.status=mess  
i++;  
if (i>=msg.length) i=1; //设置不停滚动 
setTimeout("scroll()",200); //设置滚动速度 
}  
</script>  
(2)在BODY标签中:  
<body onload="scroll()">  

19、在页面加入当前时刻  

<script language="javascript">  
tdy=new Date();  
document.write("当前光阴:",tdy.getHours());  
document.write(":",tdy.getMinutes());  
document.write(":",tdy.getSeconds());  
</script>  

20、前进、后退按键 
<input type="button" value="<-" onclick="history.go(-1)">  
<input type="button" value="->" onclick="history.go(1)">  

21、加入页面最终修改日期  
<script language="javascript">  
document.write("本页最后编辑日期:");  
document.write(document.lastModified)  
</script>  

22、前进、后退按键 
<font onclick="history.go(-1)"> 前一页</font>  
<font onclick="history.go(-2)"> 前两页</font>  
<font onclick="history.go(-3)"> 前三页</font>  
<font onclick="history.go(1)"> 后一页</font>  
<font onclick="history.go(2)"> 后两页</font>  
<font onclick="history.go(3)"> 后三页</font>  
也可安装退后、前进多步 

23、鼠标事件 
<A HREF="MAILTO:webmaster@jzzy.com" onmouseover="alert("给本身写信"); return true">信箱</A> 
鼠标放上去展现警告音信 

24、得到浏览器的属性 
navigator.appCodename=undefinednavigator.appName=Microsoft Internet Explorernavigator.appVersion=4.0 (compatible; MSIE 5.0; Windows 98; DigExt)navigator.appAgent=undefined  

25、打字与印刷整个页面 
<font onClick="javascript:window.print()">打字与印刷本页</font> 

26、查看源码 
<input TYPE="button" NAME="view" value="查看本页的源码" onClick="window.location="view-source:" +window.location.href" class="pt9"> 

27、刷新页面 
<font onClick="history.go(0)">刷新本页</font> 

28、背景象转变 
<input TYPE="button" value="背景象转换" onClick="BgButton()"> 
<script>function BgButton() 

if (document.bgColor==#00ffff)  

document.bgColor=#ffffff; 

else{document.bgColor=#00ffff; 


</script> 

29、Title上海展览中心示音讯 
<script language="javascript1.2"> 
<!--hide 
document.title="后天是星期日" 
//--hide--> 
</script>
