哪里是在这个code中的.js文件？他们为什么叫它这样？ [英] Where is the .JS file in this code? And why are they calling it this way?

问题描述

哪里JS文件，这是异步调用JS的最快方法？

我想那么他们有PHP调用在.JS用于更新广告统计??

在code：

 ＆LT;脚本类型=文/ JavaScript的＆GT;
（功能（）{
     VAR ACC =acc_230d269_pub;
     VAR ST =nocss;
     变种或=H;
     变种E = document.getElementsByTagName（剧本）[0];
     变种D =使用document.createElement（脚本）;
     d.src =（的https：== document.location.protocol的https：//：HTTP：//）+engine.influads.com/show/+或+/+ ST + /+ ACC;
     d.type =文/ JavaScript的;
     d.async = TRUE;
     d.defer = TRUE;
     e.parentNode.insertBefore（D，E）;
 }）（）;
 ＆LT; / SCRIPT＆GT;
 

解决方案

我做你的code的可读：

  1 LT;脚本类型=文/ JavaScript的＆GT;
2（函数（）{
3 VAR ACC =acc_230d269_pub;
4 VAR ST =nocss;
5变种或=H;
6变种E = document.getElementsByTagName（剧本）[0];
7变种D =使用document.createElement（脚本）;
8 d.src =（的https：== document.location.protocol的https：//：HTTP：//）+
9engine.influads.com/show/+或+/+ ST +/+ ACC;
10 d.type =文/ JavaScript的;
11 d.async = TRUE;
12 d.defer = TRUE;
13 e.parentNode.insertBefore（D，E）;
14}）（）;
15℃/脚本＆GT;
 

• 2,14一个匿名函数包装被创建的，所以变量不能从函数外部访问（范围）


• 3＆NBSP; ACC 看起来像广告的标识符


• 4,5 ST =nocss和或=H看起来像设置调整外观


• 7,10-12 A ＆LT;脚本＆gt;的创建标记。 异步 =加载脚本将不会阻止文件的执行。 推迟= TRUE $ P $从没有被执行pvents脚本（可省略）


• 6,13新创建的脚本标签之前插入的（13）的文件中的第一个脚本标记的（6,13）的


• 8,9的URL构造：
  如果当前页面是通过安全连接传输，注入脚本也将通过HTTPS协议传输

所需的文件的扩展名被省略。此文件可以使用应用程序/ JavaScript的 MIME类型由服务器配置提供服务。

Where is the JS file and is this Async the fastest way to call JS?

I guess they then have PHP calls in the .JS for updating the Ad stats??

The code:

<script type="text/javascript">
(function(){ 
     var acc = "acc_230d269_pub";
     var st = "nocss";
     var or = "h";
     var e = document.getElementsByTagName("script")[0];
     var d = document.createElement("script");
     d.src = ('https:' == document.location.protocol ?'https://' : 'http://')+"engine.influads.com/show/"+or+"/"+st+"/"+acc;
     d.type = "text/javascript"; 
     d.async = true;
     d.defer = true;
     e.parentNode.insertBefore(d,e);
 })();
 </script>

解决方案

I've made your code more readable:

1 <script type="text/javascript">
2 (function () {
3   var acc = "acc_230d269_pub";
4   var st = "nocss";
5   var or = "h";
6   var e = document.getElementsByTagName("script")[0];
7   var d = document.createElement("script");
8   d.src = ('https:' == document.location.protocol ? 'https://' : 'http://') +
9                "engine.influads.com/show/" + or + "/" + st + "/" + acc;
10  d.type = "text/javascript";
11  d.async = true;
12  d.defer = true;
13  e.parentNode.insertBefore(d, e);
14 })();
15 </script>

• 2,14 An anonymous function wrapper is created, so that variables cannot be access from outside the function ("scope")
• 3   acc looks like the identifier of the advertiser
• 4,5 st = "nocss" and or = "h" looks like settings to adjust the appearance
• 7,10-12 A <script> tag is created. async = Loading the script will not block the execution of the document. defer=true prevents the script from not being executed (can be omitted)
• 6,13 The newly created script tag is inserted before (13) the first script tag in the document (6,13)
• 8,9 The URL is constructed:
  If the current page is transmitted over a secure connection, the injected script will also be transferred over the HTTPS protocol.

The extension of the requested file is omitted. This file could be served using the application/javascript MIME type by server configuration.
