如何浏览JSON对象

Question

I am trying to navigate through a json object to return 1 element at a time and iterate through. Here's the JSON.

{
  "noun": {
    "syn": [
      "leap",
      "saltation",
      "startle",
      "start",
      "parachuting",
      "jumping",
      "actuation",
      "descent",
      "inborn reflex",
      "increase",
      "innate reflex",
      "instinctive reflex",
      "physiological reaction",
      "propulsion",
      "reflex",
      "transition",
      "unconditioned reflex"
    ]
  },
  "verb": {
    "syn": [
      "leap",
      "bound",
      "spring",
      "startle",
      "start",
      "leap out",
      "jump out",
      "stand out",
      "stick out",
      "rise",
      "climb up",
      "jump off",
      "derail",
      "chute",
      "parachute",
      "jumpstart",
      "jump-start",
      "pass over",
      "skip",
      "skip over",
      "alternate",
      "alter",
      "appear",
      "assail",
      "assault",
      "attack",
      "change",
      "climb",
      "dive",
      "drop",
      "enter",
      "go",
      "leave out",
      "locomote",
      "look",
      "miss",
      "mount",
      "move",
      "neglect",
      "omit",
      "overleap",
      "overlook",
      "participate",
      "plunge",
      "plunk",
      "pretermit",
      "seem",
      "set on",
      "shift",
      "start up",
      "switch",
      "travel",
      "vary",
      "wax"
    ],
    "rel": [
      "leap out",
      "jump on"
    ]
  }
}

Let's say I wanted to access "leap." It's two layers in. How would I 1) return leap, and 2) iterate to the next word?

Answer 1

Is this what you are looking for?

Object.keys(my_hash).forEach(function (key) { 
    Object.keys(my_hash[key]).forEach(function (key2) { 
        for(var i=0;i<my_hash[key][key2].length;i++) {
            // Process here - You have access to all your words!
            console.log(my_hash[key][key2][i]);
        }
    })
})

Answer 2

I thought you wanna do something like this.

//Your array
var array = {"noun":{"syn":["leap","saltation","startle","start","parachuting","jumping","actuation","descent","inborn reflex","increase","innate reflex","instinctive reflex","physiological reaction","propulsion","reflex","transition","unconditioned reflex"]},"verb":{"syn":["leap","bound","spring","startle","start","leap out","jump out","stand out","stick out","rise","climb up","jump off","derail","chute","parachute","jumpstart","jump-start","pass over","skip","skip over","alternate","alter","appear","assail","assault","attack","change","climb","dive","drop","enter","go","leave out","locomote","look","miss","mount","move","neglect","omit","overleap","overlook","participate","plunge","plunk","pretermit","seem","set on","shift","start up","switch","travel","vary","wax"],"rel":["leap out","jump on"]}};

//The list you want to iterate
var words = array.noun.syn;

//Iterating in the array
    for (i=0; i<words.length; i++) {
        //Words[i] is every value return after leap (including itself)
        console.log(words[i]);
    }
