按第5个字段对多维数组进行排序

Question

我有一个数组数组（2维）：

var myArray = [
    ["DVD Title 1","label1","releasedate2","details1", 5241.2541],
    ["DVD Title 1","label3","releasedate1","details1", 8452.654],
    ["DVD Title 1","label3","releasedate2","details1", 45465.5465],
    ["DVD Title 1","label2","releasedate1","details1", 451.545],
    ["DVD Title 1","label1","releasedate1","details1", 7458.6545],
    ["DVD Title 2","label2","releasedaten","detailsn", 4545.545],
    ["DVD Title 2","label1","releasedaten","detailsn", 545.545]
];

我想对这个数组进行排序，按升序排序，按第5个字段（浮点数）。

有可能吗？

Answer 1

myArray.sort(function(a,b){
    return a[4] - b[4];
});
