以特定順序創建新陣列

Question

解決了特定的承諾後，我希望遍歷響應中的每個項目，並按特定順序將它們推送到數組中。

1. status-start
2. status-in-progress
3. status-completed

我怎麼能去這樣做？這是我到目前爲止的代碼：

dashService.getBatches(refresh) 
.then(function (response) { 
    if (response.error) { 
    console.log("No data received"); 
    } else { 
    angular.forEach(response.items, function (item) { 
     if (item.status === 'start') { 
     currentBatches.push(job); 
     } 
    }); 
    } 
}); 

Answer 1

這個怎麼樣

var newA=dataList.filter(x=>x.status=='status-start').concat(dataList.filter(x=>x.status=='status-in-progress')).concat(dataList.filter(x=>x.status=='status-completed'))

一旦你得到您的回覆，請執行下列操作：

dataList = response.items; 
    var currentBatches = []; 

    var statusStartItems = dataList.filter(function(item){ return item.status === 'status-start';}); 
    //Loop through status-start items and push into currentbatches array 
    statusStartItems.each(function(item){ 
     currentBatches.push(item); 
    } 

    var statusInItems = dataList.filter(function(item){ return item.status === 'status-in';}); 
    //Loop through status-in items and push into currentbatches array 
    statusInItems .each(function(item){ 
     currentBatches.push(item); 
    } 

..所以在

我會創建可用選項的映射及其相應的順序，然後根據該映射對您的值進行排序以插入。然後，一旦排序迭代數組推送到您的目標數組。這或者你可以連接他們一旦排序產生一個新的數組。

const orderMap = { 
    'status-start': 0, 
    'status-in-progress': 1, 
    'status-completed': 2 
}; 

newData.sort((a, b) => { 
    return orderMap[a] - orderMap[b]; 
}).forEach(d => { 
    originalData.push(d); 
}); 

Heres a fiddle

顯然，你將需要改變對象的結構等，這僅僅是一個概念證明。這也是用ES6編寫的，所以沒有IE，但可以很容易地在ES5中編寫。

編輯：我看到你的排序是基於更新的演示，以反映子屬性status。

作爲一個選項，你也可以有可能被連接成一個結果，一個3個不同的排列：

var dataList = [ 
 
    {id: 11, status: 'status-start'}, 
 
    {id: 2, status: 'status-completed'}, 
 
    {id: 3, status: 'status-in-progress'}, 
 
    {id: 4, status: 'status-start'}, 
 
    {id: 5, status: 'status-completed'}, 
 
    {id: 6, status: 'status-in-progress'}, 
 
    {id: 7, status: 'status-start'}, 
 
    {id: 8, status: 'status-start'}, 
 
    {id: 9, status: 'status-in-progress'}, 
 
    {id: 10, status: 'status-start'}, 
 
    {id: 11, status: 'status-completed'}, 
 
    {id: 1, status: 'status-completed'} 
 
]; 
 

 
var currentBatches = [], 
 
currentStartedBatches = [], 
 
currentInProgressBatches = [{id: 200, status: 'status-in-progress'}], 
 
currentCompletedBatches = [{id: 12, status: 'status-completed'}, {id: 119, status: 'status-completed'}]; 
 

 
currentStartedBatches = currentStartedBatches.concat(dataList.filter(function(d){ return d.status ==='status-start' })); 
 

 
currentInProgressBatches = currentInProgressBatches.concat(dataList.filter(function(d){ return d.status ==='status-in-progress' })); 
 

 
currentCompletedBatches = currentCompletedBatches.concat(dataList.filter(function(d){ return d.status ==='status-completed' })); 
 

 
currentBatches = currentBatches.concat(currentStartedBatches).concat(currentInProgressBatches).concat(currentCompletedBatches); 
 

 
console.log(currentBatches);
