与数组作为价值排序的JavaScript对象 [英] Sort javascript object with array as value

问题描述

我在格式Javascript对象键：对其中对是包含2时间戳值的数组。我想这个排序的对象，以便用最低的数字（最早的时候）的元素首先显示出来。

I have a Javascript Object in the format key:pair where the pair is an array containing 2 timestamp values. I would like to sort this object so that the elements with the lowest numbers (earliest times) are displayed first.

下面是对象的一个​​例子： <$c$c>{\"21_2\":[1409158800,1409160000],\"20_1\":[1409148000,1409149200],\"56_1\":[1409149800,1409151600]}

Here is an example of the object: {"21_2":[1409158800,1409160000],"20_1":[1409148000,1409149200],"56_1":[1409149800,1409151600]}

因此​​，在这种情况下，我想最终排序的对象读取：

So in this case, I would want the final sorted object to read:

<$c$c>{\"20_1\":[1409148000,1409149200],\"56_1\":[1409149800,1409151600],\"21_2\":[1409158800,1409160000]}

显然排序（）功能将开始发挥作用，这里的阵列，但我如何访问对象内部的价值观？注意对象键实际上不是一个整数，因为下划线。

Obviously the sort() function will come into play here for the arrays, but how do I access those values inside the object? Note the object key isn't actually an integer because of the underscore.

我发现这个：数组内的排序一系列复杂通过值但一直无法将它应用到我的情况。任何帮助将大大AP preciated。

I have found this: Sort Complex Array of Arrays by value within but haven't been able to apply it to my situation. Any help would be greatly appreciated.

推荐答案

您可以改变你的数据的结构是这样的：

You could change the structure of your data like this:

var myArray = [{
        "id" : "21_2" // id or whatever these are
        "timeStamps" : [1409158800,1409160000]
    }, {
        "id" : "20_1"
        "timeStamps" : [1409148000,1409149200]
    }];

然后，你可以通过常规的数组排序排序是：

Then you could sort it by the regular array sort:

myArray.sort(function(a, b){
    // however you want to compare them:
    return a.timeStamps[0] - b.timeStamps[0]; 
});
