如何根據名稱對此JavaScript對象進行排序，然後按相關性排序？

Question

我問較早以下問題：Can JavaScript or jQuery sort a JSON array on multiple criteria?

我想可能是在問這個問題，因爲我指定一個JavaScript陣列，而不是一個對象都犯了一個錯誤，並且看起來這種差異是困難的根源我正在經歷。

我存在我的網頁，這是用於自動完成功能由JSON定義了以下對象：

var fundList = [ 
    { "name": "Pension Managed Fund 1", "id": 21, "cid": "N0", "dupId": 53 }, 
    { "name": "Managed Property Fund 2", "id": 407, "cid": "N0", "dupId": 58 }, 
    { "name": "Retirement Managed Fund 3", "id": 640, "cid": "N0", "dupId": 111 }, 
    { "name": "Retirement Managed Fund 4", "id": 752, "cid": "N0", "dupId": 115 } 
] 

我需要按字母順序基於他們的名字這些項目進行排序，但他們也有

Managed Property Fund 2 

Pension Managed Fund 1 

Retirement Managed Fund 3 

Retirement Managed Fund 4 

：由所述相關性輸入到文本框的值（這觸發automcomplete）

因此，例如，如果用戶鍵入「託管」到文本框，列表上方將被排序如下進行排序

如果他們輸入了「退休」，該列表將被排序，

Retirement Managed Fund 3 

Retirement Managed Fund 4 

Managed Property Fund 2 

Pension Managed Fund 1 

如果「基金」類型的，順序將是正常的字母順序排列：

Managed Property Fund 2 

Pension Managed Fund 1 

Retirement Managed Fund 3 

Retirement Managed Fund 4 

我需要做什麼來能夠根據我指定的名稱和標準對此進行排序嗎？我試圖按照上一個問題的建議使用fundList.sort(new function(a, b)，但是它返回一個未定義函數的錯誤。

您應該認真閱讀關於javascript的how to sort arrays。

下面是做這件事：

var fundList = [ 
     { "name": "Pension Managed Fund 1", "id": 21, "cid": "N0", "dupId": 53 }, 
     { "name": "Managed Property Fund 2", "id": 407, "cid": "N0", "dupId": 58 }, 
     { "name": "Retirement Managed Fund 3", "id": 640, "cid": "N0", "dupId": 111 }, 
     { "name": "Retirement Managed Fund 4", "id": 752, "cid": "N0", "dupId": 115 } 
    ], 
    textEntered = 'Managed'; 

fundList.sort(function(a, b) 
{ 
    var aStart = a.name.match(new RegExp('^'+textEntered, 'i')) || [], 
     bStart = b.name.match(new RegExp('^'+textEntered, 'i')) || []; 

    if (aStart.length != bStart.length) return bStart.length - aStart.length; 

    else return a.name > b.name ? 1 : -1; 
});

var fundList = [ 
     { "name": "Pension Managed Fund 1", "id": 21, "cid": "N0", "dupId": 53 }, 
     { "name": "Managed Property Fund 2", "id": 407, "cid": "N0", "dupId": 58 }, 
     { "name": "Retirement Managed Fund 3", "id": 640, "cid": "N0", "dupId": 111 }, 
     { "name": "Retirement Managed Fund 4", "id": 752, "cid": "N0", "dupId": 115 } 
    ], 
    textEntered = 'Managed'; 

fundList.sort(function(a, b) 
{ 
    ai = a.name.indexOf(textEntered); 
    bi = b.name.indexOf(textEntered); 
    if(ai>=0 && bi<0) return -1; 
    else if(bi>=0 && ai<0) return 1; 
    else return a.name - b.name; 
});
