以特定顺序创建新阵列

Question

解决了特定的承诺后，我希望遍历响应中的每个项目，并按特定顺序将它们推送到数组中。

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

我怎么能去这样做？这是我到目前为止的代码：

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

这个怎么样

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'))

一旦你得到您的回复，请执行下列操作：

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

我会创建可用选项的映射及其相应的顺序，然后根据该映射对您的值进行排序以插入。然后，一旦排序迭代数组推送到您的目标数组。这或者你可以连接他们一旦排序产生一个新的数组。

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

显然，你将需要改变对象的结构等，这仅仅是一个概念证明。这也是用ES6编写的，所以没有IE，但可以很容易地在ES5中编写。

编辑：我看到你的排序是基于更新的演示，以反映子属性status。

作为一个选项，你也可以有可能被连接成一个结果，一个3个不同的排列：

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);
