根据预定义的顺序在Javascript中对数组进行排序

Question

我有一个数组:

var homes = [{
    "h_id": "3",
    "city": "Dallas",
    "state": "TX",
    "zip": "75201",
    "price": "162500"
}, {
    "h_id": "4",
    "city": "Bevery Hills",
    "state": "CA",
    "zip": "90210",
    "price": "319250"
}, {
    "h_id": "5",
    "city": "New York",
    "state": "NY",
    "zip": "00010",
    "price": "962500"
}];

并希望根据以下顺序对其进行排序

cities = ['New York', 'Dallas', 'Bevery Hills']

实现它的最佳方法是什么？

Answer 1

请注意,Array.prototype.sort()方法在适当的位置进行排序,因此sort会发生变化.

homes.sort(function (a,b){
  return cities.indexOf(a.city) - cities.indexOf(b.city)
});
