Getting Dropdown CheckBoxList values using javascript

Question

I've got a ListBox inside a DropDownEdit .

Now I need to get selected values using javascript. The problem is seeing multiple instances of both in debugger, so I don't undestand how to get values I need.

My ASP.NET and javascript code: https://jsfiddle.net/dgaxvxnz/

Google Chrome Debugger shows these inputs: http://textuploader.com/dslkh

Since my reputation is below 10, I can't post more than 2 links, so I linked DevExpress source code, I took as sample, in Debugger output above.

Answer 1

Found a solution. To get chosen options I took dde_ResourceGroup_DDD_lbx_ResourceGroup_0_VI value, which is something like this: "1|21|41|51|62|13" . Of course, it had to be parsed. So, the chosen values are: 2, 4, 5, 6, 13 . I still wonder, why it has 1 or 2 at the beginning and after each symbol but last and what does it depend on.
