Accessing fields in JSON object

Question

In my JSON object I am trying to access the "name" field within "pos"

I have tried obj.tokens.pos.parent; obj[0].pos.parent;

How can I access the parent field of this object?

the object looks like

[
 {
  "tokens": [
  {
   "text": "call",
   "normalised": "call",
   "end": true,
   "start": true,
   "pos": {
    "name": "infinitive verb",
    "example": "eat",
    "parent": "verb",
    "tense": "present",
    "tag": "VBP"
  },
  "pos_reason": "lexicon",
  "analysis": {
   "word": "call",
   "next": null,
   "last": null,
   "form": "infinitive",
   "tense": "present",
    "which": {
     "name": "infinitive verb",
     "example": "eat",
     "parent": "verb",
     "tense": "present",
     "tag": "VBP"
  },
  "negative": false
 }
 }
 ]
}
]

console.log(gotIt[0].tokens[0].pos.parent); When I print this out I get the correct value but I get an error Uncaught TypeError: Converting circular structure to JSON — user3404290, Jun 27 '14 at 04:18
Also please state clear next time what exactly do you want. You started off by mentioning "name" field then you are mentioning that you are trying to get the "parent" field. Anyways, you know the syntax now to access any .. :) — antoniovassell, Jun 27 '14 at 04:22

Here the result is in array format so you need to access array element like obj[0]

obj[0].tokens[0].pos.name

Try using: obj[0].tokens[0].pos.name

I'm not sure what exactly you want, but you can try this

obj[0]["tokens"][0]["pos"]["name"]

This should work.

obj[0].tokens[0].pos.name

Are you sure? You simple do this for example: alert(obj[0].tokens[0].pos.parent);That worked for me. Assuming that you made var obj = [ .... all that you have up there. – antoniovassell Jun 27 '14 at 04:19
Actually that works. but the problem now is that I have multiple objects within tokens and I am trying to access each field by doing alert(obj[0].tokens[i].pos.parent) in a for loop but I only get the value from the first object – user3404290 Jun 27 '14 at 04:37
OK, could I see that for loop definition? – antoniovassell Jun 27 '14 at 04:40
for(var i = 0; i < obj.length; i++){ console.log(obj[0].tokens[i].pos.parent)} I think my condition is probably wrong. – user3404290 Jun 27 '14 at 04:42
OK, this will only loop 1 time, if you only have 1 object. "i < obj.length" ..... Understand? It would have to be "i < obj[0].tokens.length; ..." – antoniovassell Jun 27 '14 at 04:46
