my json file :
 {
   "divOne": {
     "underOne": [{
         "A": "x1",
         "B": "y1",
         "C": "z1"
       },
       {
         "A": "x2",
         "B": "y2",
         "C": "z2"
       }
     ],
     "underTwo": [{
         "A": "x3",
         "B": "y3",
         "C": "z3"
       },
       {
         "A": "x4",
         "B": "y4",
         "C": "z4"
       }
     ]
   },
   "divTwo": {
     "underThree": [{
         "A": "x5",
         "B": "y5",
         "C": "z5"
       },
       {
         "A": "x6",
         "B": "y6",
         "C": "z6"
       }
     ],
     "underFour": [{
       "A": "x7",
       "B": "y7",
       "C": "z7"
     }, {
       "A": "x8",
       "B": "y8",
       "C": "z8"
     }]
   }
 }
I want to pick "div" and then pick "under". Click button and show results A, B and C in loop.
I really search on google and tried 17 examples but I couldn't find how. I tried use javascript and jquery.
