the multi-dimensional array obtained from the background is parsed to form a multi-box interface. After multiple selections, the data is submitted, and then the data is sent back to the background, but the format of the incoming data is different 
sources of topics and their own ideas
The format returned by requires that the first layer json string traverses the second layer children without processing, that is, the
parent and child SN composition example Security:view. My idea is to put the parent SN and child SN of checked into postForm.permissionList, then get the background parent SN matching replacement, and then empty the postForm.permissionList, submission

what result do you expect? What is the error message actually seen?
I want to know how to put it together, or if I have the wrong idea
