javascript - Check values of nested items of object -

i trying check week object's minutes , hours , cannot figure out doing wrong. week object can contain variations of day1 - day7 dont want check them specifically. want check nested hours/minutes. don't want use jquery , has work ie8. appreciated.

week = {         day1: {             hours: 6,             minutes: 20         },         day2: {             minutes: 45         },         day3: {             hours: 8,             minutes: 15         }     };  hoursinvalid = false; minutesinvalid = false;  (var item in week) {         if (week.hasownproperty(item)) {             (var = 0; < week[item].length; i++ )             {                 if (week[item][i].hours > 6) {                     hoursinvalid = true;                     break;                 }                 if (week[item][i].minutes > 20) {                     minutesinvalid = true;                     break;                 }              }         }     } 

i don't see need internal for loop. solution came with. added checks make sure dayn objects have hours , minutes properties.

week = {   day1: {     hours: 6,     minutes: 20   },   day2: {     minutes: 45   },   day3: {     hours: 8,     minutes: 15   } };  hoursinvalid = false; minutesinvalid = false;  (var item in week) {   if (week[item].hasownproperty('hours')) {     if (week[item].hours > 6) {       hoursinvalid = true;       break;     }   }   if (week[item].hasownproperty('minutes')) {     if (week[item].minutes > 20) {       minutesinvalid = true;       break;     }   } }
