按两个属性并按给定顺序对对象的JavaScript数组进行排序 [英] Sort JavaScript array of Objects by two properties and given order

问题描述

我有这个对象的JavaScript数组:

I have this JavaScript array of Objects:

data = [
    {'deviation': 57.41, 'provider': "This", 'measure': "median"},
    {'deviation': 49.02, 'provider': "All", 'measure': "median"},
    {'deviation': 199.67, 'provider': "This", 'measure': "third_quartile"},
    {'deviation': 152.31, 'provider': "All", 'measure': "third_quartile"},
    {'deviation': 41.48, 'provider': "This", 'measure': "first_quartile"},
    {'deviation': -1.07, 'provider': "All", 'measure': "first_quartile"}
]

，我想按"provider"(三个"All"之前的三个"This")和"measure"(第一个四分位数，中位数，第三个四分位数)对它进行排序，因此结果数组看起来像:

and I would like to sort it both by 'provider' (the three "This" before the three "All") and by 'measure' (first quartile, median, third quartile), so the resulting array will look like:

data = [
    {'deviation': 41.48, 'provider': "This", 'measure': "first_quartile"},
    {'deviation': 57.41, 'provider': "This", 'measure': "median"},
    {'deviation': 199.67, 'provider': "This", 'measure': "third_quartile"},
    {'deviation': -1.07, 'provider': "All", 'measure': "first_quartile"}
    {'deviation': 49.02, 'provider': "All", 'measure': "median"},
    {'deviation': 152.31, 'provider': "All", 'measure': "third_quartile"},       
]

我已经编写了一个函数作为 .sort()的参数，它确实返回了按'provider'排序的数组，但是当我使用测量作为参数(幸运的是，first_quartile，中位数，third_quartile已经按照我想要的方式按字母顺序排序)-排序被打乱了.我该怎么做呢?

I have written a function as an argument to .sort(), and it does return the array sorted by 'provider', but then when I feed it into the same function with measure as an argument (thankfully, first_quartile, median, third_quartile are already alphabetically sorted the way I want them) - the sorting gets broken. How can I go about doing it?

编辑我一直在使用的功能:

EDIT The functions I have been using:

var compare_prv = function(a,b) {
  if (a.provider < b.provider){
    return 1;
  }
  return 0;
}

var compare_meas = function(a,b) {
  if (a.measure < b.measure){
    return -1;
  }
  return 0;
}

推荐答案

听起来像您在做

data.sort(function(a, b) {
    //sort by provider
});

data.sort(function(a, b) {
    //sort by measure
});

但是您要做的是:

data.sort(function(a, b) {
    //sort by provider, but if they are equal, sort by measure
});

类似

data.sort(function(a, b) {
    if (a.provider === b.provider) {
        return a.measure.localeCompare(b.measure);
    }
    return b.provider.localeCompare(a.provider);
});
