使用数组作为排序顺序 [英] Use array as sort order

问题描述

我想使用字符串数组作为模板，如何对其他数组进行排序.

I want to use an array of strings as template how to order other arrays.

var sort = ["this","is","my","custom","order"];

然后我想按键(内容)的顺序对对象数组进行排序:

and then i want to sort an array of objects depending on a key (content) by that order:

var myObjects = [
    {"id":1,"content":"is"},
    {"id":2,"content":"my"},
    {"id":3,"content":"this"},
    {"id":4,"content":"custom"},
    {"id":5,"content":"order"}
];

所以我的结果是:

sortedObject = [
    {"id":3,"content":"this"},        
    {"id":1,"content":"is"},
    {"id":2,"content":"my"},
    {"id":4,"content":"custom"},
    {"id":5,"content":"order"}    
];

我该怎么做?

推荐答案

您可以在

var sort = ["this", "is", "my", "custom", "order"];

var myObjects = [{
  "id": 1,
  "content": "is"
}, {
  "id": 2,
  "content": "my"
}, {
  "id": 3,
  "content": "this"
}, {
  "id": 4,
  "content": "custom"
}, {
  "id": 5,
  "content": "order"
}];

var sortedObj = myObjects.sort(function(a, b) {
  return sort.indexOf(a.content) - sort.indexOf(b.content);
});

document.write('<pre>' + JSON.stringify(sortedObj, null, 3) + '</pre>');
