check if key exists in object with lodash

Question

I need help with lodash cause i dont understand functional programming and lodash is very helpfull with object/arrays operations.

I need to search objects inside object and return true if key exists. I've setup a jsfiddle. Apreciate your help.

    var dependsOn={
      "Cadastro": {
        "RHID": "RHID"
      },
      "Agregados":{
        "CD_DOC":"CD_DOC"
      }
      "Documentos":{
        "RHID":"CD_DOC"
      }
    }
    var field='RHID'

alert(_.contains(_.keys(dependsOn), field))

Try this. it's simple

_.has(dependsOn, field)

it returns true if the RHID key exist in dependsOn. in above case it returns false

var dependsOn={
  "Cadastro": {
    "RHID": "RHID"
  },
  "Agregados":{
    "CD_DOC":"CD_DOC"
  },
  "Documentos":{

alert(_.some(dependsOn, function(o) { return _.has(o, field); }));
