Javascript：为在VMware vCenter中创建目录树而进行循环嵌套

首先，您可以通过我的代码得知，我不是程序员，我不知道JavaScript。我实际上正在使用VMware Orchestrator（基于Rhino JavaScript引擎，我相信）来创建一些工作流程。请详细解释任何答案。Javascript：为在VMware vCenter中创建目录树而进行循环嵌套

我想创建一个工作流程，在vCenter中创建一个目录树。

概念：基本上我试图为调用全局树的树的每一层运行嵌套for循环。

问题： 1st for循环工作并创建文件夹“Dev”。第二个for循环不与错误信息的工作：

[2013-06-27 19:16:16.219] [I] Building folder Dev 
[2013-06-27 19:16:16.474] [I] Built directory: Dev 
[2013-06-27 19:16:16.476] [I] Building folder Servers 
[2013-06-27 19:16:16.480] [I] TypeError: Cannot find function createFolder in object Dev. (Workflow:TEST_TNG_New_Site_Folder_Structure/Scriptable task (item2)#36)

我认为这与JavaScript不能够调用全局函数到嵌套对象做（我不是一个程序员，不知道的JavaScript所以不要拍我在此）

代码：（将一旦我得到它的工作清理它）

var folderBase = ["Dev","DMZ","Prod","UAT"]; 

var folderT1 = ["Servers","Workstations"]; 

var folderT2 = ["Windows","Linux"]; 

var folderT3 = ["Repo1","Repo2","Repo3","Repo4"]; 

var folderT4 = ["T1","T2","T3"]; 



// Create the folderBase level of folders 

for (var i=0,l=folderBase.length; i<l; i++) { 

    var rootFolder = parentFolder; 

    buildFolderTree(folderBase[i]); 

     // Create the folderT1 level of folders 

     for (var j=0, l=folderT1.length; j<l; j++) { 

      var rootFolder = folderBase[i]; 

      buildFolderTree(folderT1[j]); 

       // Create the folderT2 level of folders 

       for (var k=0, l=folderT2.length; k<l; k++) { 

        var rootFolder = folderT1[j]; 

        buildFolderTree(folderT2[k]); 

         // Create the folderT3 level of folders 

         for (var x=0, l=folderT3.length; x<l; x++) { 

          var rootFolder = folderT2[k]; 

          buildFolderTree(folderT3[x]); 

           // Create the folderT4 level of folders 

           for (var y=0, l=folderT4.length; y<l; y++) { 

            var rootFolder = folderT3[x]; 

            buildFolderTree(folderT4[y]); 

            } 

          } 

        }  

      } 

    } 



function buildFolderTree(folderName) { 

     System.log("Building folder " + folderName); 

     rootFolder.createFolder(folderName); 

     System.log("Built directory: " + folderName); 

    }

你有一个问题是JavaScript只有函数级作用域，所以你所有的循环索引和长度变量都需要有不同的名字。在你的示例中，特别是长度变量都被称为'l'，它们应该有不同的名字，比如'il'，'jl'等（或者你选择的）。 – WildCrustacean

这里是解决办法。显然，它不是嵌套for循环和全局对象，而是更多与对象引用有关（我仍然不完全理解它）。
