jquery - Cant grab indexOf - is not a function -


i have array want store name , piece of information can call item retrieve information. when try search array check first item in array receive: genrearray.indexof not function

my code:

var genrearray = {"00's":"includes amy whinehouse, westlife, killers...","90's":"includes britney spears, backstreet boys, mariah carey..."};  if(genrearray.indexof("00's") > -1) //crashed here {  //code here   console.log(genrearray["00's"]); }

genrearray object, object contains key/val pairs, not indexes. can hasownproperty

if (genrearray.hasownproperty("00's")) {  }

(so might make sense rename variable 'genreobj')
