Question

我必须对此进行排序：我从两个不同的select查询中获取数据库中的数据，我必须按mpriority和mdate对其进行排序。

我知道如何对对象数组进行排序，但我无法使用object或object.key

    var allocations = new Array(); 
    allocations[0] =
    [   qtA =  15,
        mdata=  '1234',
        mid =  '234234234',
        qtyToDoTemp=  11,
        mpriority=  5,
        mdate=  new Date('2017-04-27 11:26:02.147'),
    ];

allocations[1] =
    [
        qtA= 13,
        mdata=  '1234',
        mid =  '234234234',
        qtyToDoTemp= 11,
        mpriority= 5,
        mdate= new Date('2016-10-07 00:00:00.000'),
    ];

allocations[2] =
    [
        qtA= 16,
        mdata=  '1234',
        mid =  '234234234',
        qtyToDoTemp= 11,
        mpriority= 4,
        mdate= new Date('2017-04-27 11:26:02.147'),
    ];

allocations[3] =
    [
        qtA= 95,
        mdata=  '1234',
        mid =  '234234234',
        qtyToDoTemp= 11,
        mpriority= 1,
        mdate= new Date('2016-10-06 00:00:00.000'),
    ];

allocations[4] =
    [
        qtA= 75,
        mdata=  '1234',
        mid =  '234234234',
        qtyToDoTemp= 11,
        mpriority= 8,
        mdate= new Date('2017-02-20 12:41:34.903'),
    ];

allocations[5] =
    [
        qtA= 45,
        mdata=  '1234',
        mid =  '234234234',
        qtyToDoTemp= 11,
        mpriority= 0,
        mdate= new Date('2017-04-27 11:26:02.147'),
    ];

排序函数应首先查看mpriority - 如果两个值相同，则选中mdate

我认为会是这样的

var sortOptions = {
    byPriorityAndDate: function (a, b) {
        return (b.mpriority - a.mpriority) || (a.mdate - b.mdate);
    },
}

以及如何检查我工作的js版本？
