问题描述

我在网站上实施Google跟踪代码管理器时遇到一些问题.我有一个Google代码，当我在自己的网站上尝试该代码时，会导致很多的JavaScript冲突.

I am having some problems implementing Google Tag Manager on my website. I have a Google code, and when I try it on my site, it makes a lot of javascript conflicts.

因此，我尝试将代码放在单独的文件中，以逐步进行操作，并观察不同脚本的行为.

So I tried to put the code on a seperate file, in order to do it Step by Step and observe the behavior of the different scripts.

这是我非常简单的HTML页面:

So here my very simple HTML page:

<!DOCTYPE html>
<html>
<head>
    <title>Titre</title>
</head>
<body>
    <!-- Google Tag Manager -->
    <noscript>
    <iframe src="http://www.googletagmanager.com/ns.html?id=GTM-XXXXXX" height="0" width="0" style="display:none;visibility:hidden"></iframe>
    </noscript>
    <script type="text/javascript">
        dataLayer = [{'uid':'12'}];
        (function(w,d,s,l,i){
            w[l]=w[l]||[];
            w[l].push({'gtm.start': new Date().getTime(),event:'gtm.js'});
            var f=d.getElementsByTagName(s)[0],j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';
            j.async=true;
            j.src='//www.googletagmanager.com/gtm.js?id='+i+dl;
            f.parentNode.insertBefore(j,f);
        })(window,document,'script','dataLayer','GTM-XXXXXX');
    </script>
    <!-- End Google Tag Manager -->
    hello
</body>
</html>

此页面在JS控制台中返回错误:

And this very page, returns an error in the JS console:

Uncaught ReferenceError: jQuery is not defined

好吧，这是意外的，jQuery在这里必须做什么?我什至没有在body标签上声明它，Google是否需要jQuery?

Well, this is unexpected, what does jQuery has to do here? I didn't even declare it on my body tag, is Google requiring jQuery?

这很奇怪，第二件事，当我在浏览器中加载后查看生成的HTML页面时:

So that was weird, and the second thing, when I look on my generated HTML page, after loading on a browser:

<body>
... Long stuff here
<script type="text/javascript" id="" src="//ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
... some other stuff here
</body>

这是什么法术?为什么Google会在页面底部添加一个jquery东西，为什么我的控制台会向我显示jQuery错误?

What kind of sorcery is this? Why does Google add a jquery thing at the bottom of my page, and why does my console shows me a jQuery error?

非常感谢您提供任何信息，我完全迷路了...祝你有美好的一天！

Thanks a lot for any kind of information, I am totally lost...And have a nice day!
