如何根據其狀態跟其他字段自定義排序數組？

Question

所以我有一個數組，我需要按照以下順序對狀態進行排序，即失敗 - >警告 - >完成。 通常，我使用lodash進行排序，但它的複雜順序在這裏。它還需要按運行排序後進行排序。我不知道該如何開始。

var arr = [{"status":"failure","name":"one","run":1}, 
{"status":"failure","name":"two","run":2}, 
{"status":"warn","name":"three","run":1}, 
{"status":"warn","name":"four","run":2}, 
{"status":"completed","name":"five","run":1}] 

Answer 1

這樣的事情？

1. 爲您的排序鍵添加一個額外的屬性。

var arrnew = arr.map(function(item){ 
    switch(item.status){ 
    case "failure": 
    item.statusId=1; 
    break; 
    case "warn": 
    item.statusId=2;} 
    //... 
    return item}); 

排序通過使用

_.sortBy（arrnew， 'statusId'）;

Answer 2

排序基於「狀態」，然後通過「運行」的1或2中的子片段：

let status_vals = [ "failure", "warn", "completed" ]; 

let arr = [ 
    {"status":"failure","name":"one","run":1}, 
    {"status":"failure","name":"two","run":2}, 
    {"status":"warn","name":"three","run":1}, 
    {"status":"warn","name":"four","run":2}, 
    {"status":"completed","name":"five","run":1} 
]; 

function sortIt (status_arr, sort_arr) { 

    let sorted_arr = []; 
    status_arr.forEach (d => { 
    let temp = arr.filter (obj => { 
     return obj.status === d; 
    }); 

    var length = temp.length; 
    for (var i = 0; i < length; i++) { 
     if (temp [ 0 ].run > temp [ i ].run) { 
     temp.push (temp.shift ()); 
     } 
    } 

    sorted_arr = [ ...sorted_arr, ...temp ]; 
    }); 

    return sorted_arr; 
} 

sortIt (status_vals, arr);
