Web应用程序中的绝对路径
[英]Absolute path in a web app
问题描述
This may sound like a dumb question. 
这听起来像是一个愚蠢的问题。
I received a (basic) web application developed by another person, using HTML and JavaScript . 我收到了另一个人使用HTML和JavaScript开发的（基本）Web应用程序。 In this application he used his JavaScript file path as /javascripts/_FileName_.js . 在此应用程序中，他使用了JavaScript文件路径作为/javascripts/_FileName_.js 。 But when I tried to run it on a Tomcat (8.5) server, those JavaScript files didn't executed. 但是，当我尝试在Tomcat（8.5）服务器上运行它时，那些JavaScript文件没有执行。 But when I changed the path to javascripts/_FileName_.js (Without the / at the beginning), it worked fine. 但是，当我将路径更改为javascripts/_FileName_.js （开头没有/ ），它可以正常工作。
This application was already ran in a server and it worked fine. 该应用程序已经在服务器中运行，并且可以正常工作。 What has to be the problem here ? 这里有什么问题？

as @duffymo described in comments, the leading slash tells tomcat to start looking for that file at the root of the application context, which is the webapps folder in tomcat. 如@duffymo在评论中所述， 前导斜线告诉tomcat开始在应用程序上下文的根目录（即tomcat中的webapps文件夹）中查找该文件。 But if we remove that leading slash , it searches for the file from the current folder. 但是，如果我们删除该前导斜线 ，它将从当前文件夹中搜索文件。
That was the problem. 那就是问题所在。 I am posting this as an answer because he mentioned these in comments only. 我将其发布为答案，因为他仅在评论中提到了这些。
