js数组按照两个条件排序

你好，这个问题我这样解决的，你看下：

{name:'qqq',?num:2,time:'2015-06-08?13:44:18'},?

{name:'www',?num:3,time:'2015-06-08?13:44:18'},?

{name:'eee',?num:4,time:'2015-06-07?13:40:18'},

{name:'rrr',?num:4,time:'2015-06-08?13:44:18'},

{name:'yyy',?num:6,time:'2015-06-07?13:40:18'},?

];

arr.sort(function(a,?b){

if?(a.num?===?b.num)?{

return?new?Date(b.time.replace(/-/g,?"/"))?-?new?Date(a.time.replace(/-/g,?"/"))

}?else?{

return?b.num?-?a.num;

}

});

console.log(arr);?//?yyy,rrr,eee,www,qqq

希望是你想要的答案，望采纳~~
