[Rails] How to access the Var or function from a Javascript file in a rails function？

Hi!  I am supposed to process the specified data in my database.So this is what i am doing. First, I get the "id" attribute of the objects that i will use by checkbox. Then, I will search the database to get the objects according to the "id" list. 

But, here is my problem, I can get the "id" list, but I don;t know how to get the objects thtough the list, for the function"getPendingList" to get "id" list is in the "js" file, the function "pendingAll(list)" to get the object is a rails helper function, when i call back the  "getPendingList" like " pendingAll( getPendingList) ",it says can't find the getPendingList. 

Any advice will be appreciated, thank you~
