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))

Answer 1

Try this. it's simple

_.has(dependsOn, field) 

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

Answer 2

try this

var dependsOn={   "Cadastro": {     "RHID": "RHID"   },   "Agregados":{     "CD_DOC":"CD_DOC"   },   "Documentos":{     "RHID":"CD_DOC"   } } var field='RHID'  alert(_.some(dependsOn, function(o) { return _.has(o, field); }));
