File Explorer using Dojo Tree from an Array

Question

I have an array of file names/paths. Lets say it contains:

• File1.txt
• Folder1/File2.txt
• Folder1/File3.txt
• Folder2/File4.txt
• Folder3/Folder4/File5.txt
• Folder3/File6.txt
• NewFile.txt

Now I want to create a Dojo Tree which basically displays this information in a tree structure with root as "Files" and below it appears a tree like this

• Files (ROOT)
  • File1.txt
  • Folder1
    • File2.txt
    • File3.txt
  • Folder2
    • File4.txt
  • Folder3
    • Folder4
      • File5.txt
    • File6.txt
  • NewFile.txt

I was able to create a JSON form single level tree structure. As I am hard pressed for time I need a algorithm/code snippet which can create my desired JSON file. Any ideas!?

Answer 1

Take a look at giveSortedArray() function (yeah I suck at function naming):

I used dojo.store.Memory for easier fetching of existing folders but I'm sure there are some other (possible better) solutions.
