this might be an odd question, but I have a map Long-String pair:
10 ANIMAL 11 BACTERIA 12 SHROOM
I send this HashMap from Spring Controller to View:
Map<Long, String> catMap = filterService.generateCatMap(); ... mv.addObject("catMap", catMap);
In the view I can print the key value pair easily by iterating or directly by catMap[ KEY ]
Problem is that I have a JS function where I have to pass the KEY and I know the VALUE. So this is reverse from map: get value by key.
Is it possible actually to get the key by knowing the value without iterating? (I have to mention that keys and values are unique, no duplicates)
