如何跟踪javascript文件请求的来源

Question

好的，我的自定义模板有很多问题，甚至都不好笑...

这是joomla 3.x的自定义模板...

我想找出的一个问题是缺少的javascript请求来自哪里？

我尚未发布所有模块，甚至上传了带有一些更改的新模板...

但它仍然存在！

如果您查看源代码并单击所谓的丢失文件，它会很好显示...因此，为什么在Chrome的javascript控制台中它总是说404 ！！

您如何确定请求的来源？

另外，我一直在视图源中看到它，但是不知道它是从哪里来的。

<script type="text/javascript">
    window.addEvent('load', function() {
new JCaption('img.caption');
   });
  </script>

编辑...

为了弄清楚我在说什么文件，就是这个文件：

<script src="/social/services/templates/testingdifferentversion16/js/jquery-1.10.1.min.map.js" type="text/javascript"></script>

如果您查看视图源，则可以很好地访问它。

如果看到找不到它的错误，因此出现404，则文件确实丢失。

这就是为什么这篇文章写起来，为了找到此请求的来源。

希望此编辑可以使事情变得更简单。

## Mod_rewrite in use.

RewriteEngine On

## Begin - Rewrite rules to block out some common exploits.
# If you experience problems on your site block out the operations listed below

#
# Block out any script trying to base64_encode data within the URL.
RewriteCond %{QUERY_STRING} base64_encode[^(]*\([^)]*\) [OR]
# Block out any script that includes a <script> tag in URL.

检查根目录中是否有.htaccess文件，然后检查该文件中是否有mod_rewrite规则。 许多CMS软件包都使用mod_rewrite来处理整个站点的导航。 如果您正在使用Filezilla for FTP之类的程序，请确保该程序在选项中设置了“显示隐藏文件”，否则您甚至可能看不到.htaccess文件。 如果有，请在您的问题中张贴其内容。

我很快看了一下，是的，Joomla确实使用了mod_rewrite来控制网站中的流量，并且由此产生了多个错误。

http://forum.joomla.org/viewtopic.php?f=304&t=346374

这是一个与您的问题不完全相同的链接，但它确实使您了解如何使用.htaccess弄乱事情。 给我更多信息，我们将继续。

好吧，如果您尝试访问此文件，则必须将其直接放在地址栏中。 如果查看mod_rewrite规则，您将看到，如果URL以“ /”结尾或不以扩展名结尾，那么它将在其末尾添加“ index.php”。

那有意义吗？

@ user2730725这也让我发疯了！ 该文件是.map文件，仅用于调试目的。 通过打开Chrome Dev Tools，然后依次单击“设置”和“常规”中的“启用JS源映射”复选框，关闭尝试检索它的设置。 取消选择。 问题解决了。 :)
