javascript - Multi-sorting a multi-dimensional array

Question

var availableTags = [
    {value:"fruit",desc:"fruit",groupId:2,userId:4},
    {value:"aGan",desc:"normal user",groupId:4,userId:5},
    {value:"father's home ",desc:"normal user",groupId:2,userId:4}     

  ].sort(function(a, b) {  return a.groupId > b.groupId; });

This sorts by groupId field, but how do I to sort by groupId and value?

Answer 1

Change the return statement to

return a.groupId > b.groupId || (a.groupId == b.groupId && a.value > b.value);
