i'm having simple json file looks like:

{  "seasons" : {     "s_1" : {         "episodes" : 7     },     "s_2" : {         "episodes" : 21     },     "s_3" : {         "episodes" : 22     },     "s_4" : {         "episodes" : 30     },     "s_5" : {         "episodes" : 18     },     "s_6" : {         "episodes" : 12     }   } } 

and want randomly select s_ x value seasons when parsing file:

var random = math.floor(math.random() * 6) + 1;     $.getjson('js/data.json', function(data) {                  console.log(data.seasons.s_+random);     }); 

this not work. how correct way? thanks

console.log(data.seasons["s_"+random]); 

using brackets becomes data.seasons["s_1"]
