Getting undefined from javascript array of arrays -

this linked previous question different , whole new question... have array, after nice php looks this:

var series = {     "001":{         "game":"portal 2",         "name":"portal 2"     },     "002":{         "game":"minecraft",         "name":"241"     },     "003":{         "game":"minecraft",         "name":"hackmine"     },     "004":{         "game":"mass effect 3",         "name":"mass effect 3"     },     "005":{         "game":"league of legends",         "name":"league of legends"     },     "006":{         "game":"half life 2",         "name":"the hidden: source"     },     "007":{         "game":"skyrim",         "name":"modded skyrim"     } } 

this bit populated fine... question when function called, gives game , name value undefined

function seriesidonblur() {             var id = parseint(document.getelementbyid("series_id").value);      if (series[id] == null)     {         var message = "the series id input invalid";     }     else     {         var seriesid = series[id];          var game = seriesid['game'];         var name = seriesid['name'];         var message = "you've inputted id game: " + game + " series: " + name;     }      document.getelementbyid("series_id_check").innerhtml = message; } 

you're shooting in foot leading 0s: series['001'] not same series['1']. either cut parseint call (forcing user type '001'), drop leading 0s:

var series = {     "1":{         "game":"portal 2",         "name":"portal 2"     },     ...     "7":{         "game":"skyrim",         "name":"modded skyrim"     } } 

or use array:

var series = [     {         "game":"portal 2",         "name":"portal 2"     },     ...     {         "game":"skyrim",         "name":"modded skyrim"     } ]
