数组内的对象按照2个属性进行排序(先按time从大到小排序，再按weight从大到小排序)，请查看控制台看输出结果:<br/>
var array = [<br/>{time: 1, weight: 4},<br/> {time: 1, weight: 1}, <br/>{time: 1, weight: 9}, <br/>{time: 2, weight: 4},
<br/>{time: 2, weight: 1}, <br/>{time: 2, weight: 5}<br/>];
<script>
    //先按time从大到小排序，再按weight从大到小排序
    var array = [{time: 1, weight: 4}, {time: 1, weight: 1}, {time: 1, weight: 9}, {time: 2, weight: 4}, {time: 2,weight: 1}, {time: 2, weight: 5}];
    array.sort(function (a, b) {
        if (a.time !== b.time) {
            return b.time - a.time;
        } else {
            return b.weight - a.weight;
        }
    });
    var len = array.length;
    for (var i = 0; i < array.length; i++) {
        console.log("{time:" + array[i].time + ",weight:" + array[i].weight + "}\n");
    }
</script>
