首先，正如您可以通过我的代码所说的那样，我不是程序员，也不知道 javascript。我实际上正在使用 VMware Orchestrator（我相信它基于 Rhino javascript 引擎）来创建一些工作流。请详细解释任何答案。

我正在尝试创建一个将在 vCenter 中创建目录树的工作流。

概念：基本上我试图为调用全局树的树的每一层运行嵌套的 for 循环。

问题：第一个 for 循环工作并创建文件夹“Dev”。第二个 for 循环不起作用并出现错误消息：

[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 无法将全局函数调用到嵌套对象中有关（我不是程序员，也不知道 JavaScript，所以不要在这方面开枪）

代码：（一旦我开始工作就会清理它）

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);

    }

这是解决方案。显然它与嵌套的 for 循环和全局对象无关，而更多地与对象引用有关（我仍然不完全理解它）。
