简化JS中的嵌套父子代码
我的JS代码构造很差，需要使用do-while或for (i=0;i<10;i++)这样的增量来缩短。该脚本可以正常运行，但外观不佳。
我正在尝试将VMware中的文件夹树结构导出到具有两个属性（“文件夹名称”和“文件夹路径”）的对象数组中。我使用vCenter插件查询数据。这是库存图片-
这是代码-
function getFolderPath(dc)
{
var row = [];
var VcFolders = VcPlugin.getAllVmFolders()
for each(VcFolder in VcFolders)
{
if (VcFolder.sdkConnection.name.match(dc.sdkConnection.name))
{
if (VcFolder.name == "vm")
{
if (VcFolder.parent instanceof VcDatacenter)
{
if (VcFolder.parent.name == dc.name)
{
var parentFolder = VcFolder;
for each (child in parentFolder.childEntity)
{
if (child.vimType == "Folder")
{
var current = child.parent
var path = child.name
do {
var parent = current
if (parent.name != "vm")
{
path = parent.name + "\\" + path
}
current = current.parent
} while (current.parent != null)
row.push({
Name: child.name,
Path: path
})
for each (child1 in child.childEntity)
{
if (child1.vimType == "Folder")
{
var current = child1.parent
var path1 = child1.name
do {
var parent = current
if (parent.name != "vm")
{
path1 = parent.name + "\\" + path1
}
current = current.parent
} while (current.parent != null)
row.push({
Name: child1.name,
Path: path1
})
for each (child2 in child1.childEntity)
{
if (child2.vimType == "Folder")
{
var current = child2.parent
var path2 = child2.name
do {
var parent = current
if (parent.name != "vm")
{
path2 = parent.name + "\\" + path2
}
current = current.parent
} while (current.parent != null)
row.push({
Name: child2.name,
Path: path2
})
for each (child3 in child2.childEntity)
{
if (child3.vimType == "Folder")
{
var current = child3.parent
var path3 = child3.name
do {
var parent = current
if (parent.name != "vm")
{
path3 = parent.name + "\\" + path3
}
current = current.parent
} while (current.parent != null)
row.push({

for each (child4 in child3.childEntity)
{
if (child4.vimType == "Folder")
{
var current = child4.parent
var path4 = child4.name
do {
var parent = current
if (parent.name != "vm")
{

current = current.parent
} while (current.parent != null)
row.push({

for each (child5 in child4.childEntity)

if (child5.vimType == "Folder")
{
var current = child5.parent
var path5 = child5.name
do {
var parent = current
if (parent.name != "vm")
{
path5 = parent.name + "\\" + path5
}
current = current.parent
} while (current.parent != null)
row.push({
Name: child5.name,
Path: path5
})
for each (child6 in child5.childEntity)
{
if (child6.vimType == "Folder")
{
var current = child6.parent
var path6 = child6.name
do {
var parent = current
if (parent.name != "vm")
{
path6 = parent.name + "\\" + path6
}
current = current.parent
} while (current.parent != null)
row.push({

for each (child7 in child6.childEntity)
{
if (child7.vimType == "Folder")
{
var current = child7.parent
var path6 = child7.name
do {
var parent = current

}
}
}
}
}
}
}
}
}
}
}
}
}
}
}
}
}
}
}
}
}
}
return row
}
vcs = VcPlugin.allSdkConnections
for each (vc in vcs)
{
var dcs = vc.getAllDatacenters()
for each (dc in dcs)
{
System.log("Getting folder path in '"+dc.name+"'...")
var paths = getFolderPath(dc)
for (i = 0; i < paths.length; i++)
{
System.log("Name:- " + paths[i].Name + " Path:- " + paths[i].Path);
}
}
}
如您所见，我已经将子代码嵌套了八次。这是一个坏习惯，因为根据环境的不同，任何时候嵌套文件夹的数量都可能超过8。我还试图将每个孩子的父母添加到“行” array中，以至于无法思考如何使用do-while。
这是预期的输出-

只是一种抽象方法（我仍然怀疑代码是Javascript而不是Java）。
这是一种yopur代码模式，您可以在其中迭代一些数据，检查类型并迭代路径。最后，您将一个新对象放入row。
for (child in parentFolder.childEntity) { // *in* maybe wrong, just to mention ...
if (child.vimType == "Folder") {
var current = child.parent
var path = child.name
do {
var parent = current
if (parent.name != "vm") path = parent.name + "\\" + path;
current = current.parent
} while (current.parent != null)
row.push({ Name: child.name, Path: path });
// next same pattern with child.childEntity
}
}
您可以将此模式转换为函数，并交出用于迭代的数据和目标数组row（或者如果不是嵌套函数，也可以不这样做）。
然后进行否定检查，并在没有嵌套块的情况下继续循环。
然后获取路径值并推送对象。
最后退出递归调用或使用新数据再次调用该函数。在您的代码中，您阻止了嵌套方法，在这里，您可以检查child.childEntity是否虚假。
function iter(data, row) {
for (child in data) {
if (child.vimType !== "Folder") continue;
var current = child.parent
var path = child.name
do {
var parent = current;
if (parent.name !== "vm") path = parent.name + "\\" + path;
current = current.parent
} while (current.parent != null)
row.push({ Name: child.name, Path: path });
if (!child.childEntity) continue;
iter(child.childEntity, row);
}
}
// call
iter(parentFolder.childEntity, row);
