如何合並、排序和循環 JavaScript 對象？

Question

我有一個循環，它返回整數值和對象，如下所示：

2
{firstName:"John", lastName:"Doe", age:28, eyeColor:"blue"}
3
{firstName:"Jane", lastName:"Doe", age:22, eyeColor:"brown"}
1
{firstName:"Jack", lastName:"Doe", age:50, eyeColor:"red"}

這些是在循環內逐行返回的不同值。 我需要根據數字的排序順序遍歷對象，並在兩個不同的變量中獲取數字和每個對象。 我需要得到並能夠遍歷它的是：

1
{firstName:"Jack", lastName:"Doe", age:50, eyeColor:"red"}
2
{firstName:"John", lastName:"Doe", age:28, eyeColor:"blue"}
3
{firstName:"Jane", lastName:"Doe", age:22, eyeColor:"brown"}

所以我將能夠在這樣的函數中使用它：

loop sorted 
    some_function(number_variable, object_variable);
end loop

我需要按特定順序調用它們，因為它們用於網格列重新排序。

我試圖將對象推送到數組中，但我將如何根據其他數值對這些對象進行排序？

提前致謝！

Answer 1

您可以基於數字生成對象的結果數組，如index = number-1

var nums = [2,3,1];
var objects = [
{firstName:"John", lastName:"Doe", age:28, eyeColor:"blue"},
{firstName:"Jane", lastName:"Doe", age:22, eyeColor:"brown"},
{firstName:"Jack", lastName:"Doe", age:50, eyeColor:"red"}
];
var sortedObjects = nums.map(function(num) {return objects[num-1]});
sortedObjects.forEach(function(obj, i) {some_function(nums[i], obj)})
