與其他JSON文件

對象替換字符串我有3個JSON文件：與其他JSON文件

sources.json
destination_level1.json
destination_level0.json（最後文件）

我想通過替換匹配的字符串「合併」所有這些文件，例如

destination_level0 - > destination_level1 - > sources

用詞語：「檢查destination_level0中的鍵例如「部件1」，去destination_level1和查找匹配的對象，並在destination_level0與對象替換部件1「也是一樣從destination_level1消息人士透露

來源可能是這樣的：。

{"john": ["A","B"],"mike": ["123","234","345"],"doe": ["abc","cde"],"ann": {"abc": ["yxc","xcv","cvb"],"bcd": ["poi","iuz","uzt"]}}

destination_level_1像這樣的：

{"Element1": ["john","ann","john","john","doe","mike"],"Element2": ["ann","mike","ann","doe","doe","doe","ann"],"Element3": ["ann","doe","ann"]}

和destination_level_0這樣的：

{"FinalA": ["Element1","Element2","Element1","Element2","Element2"],"FinalB": ["Element2","Element2","Element2","Element1"]}

最後的結果應該是這樣的：

{"FinalA": [[["A","B"],{"abc": ["yxc","xcv","cvb"],"bcd": ["poi","iuz","uzt"]},...

我已經嘗試了一些lodash &底線，但卡住了。

任何想法？

element2從哪裏來？ finalB從哪裏來？關係不清楚！ –

element2在destination_level0.json中手動定義。 finalB一樣。 element2應該替換爲destination_level_1中element2的對象。由於這是我們將要使用的最終「關鍵」，因此finalB不需要被替換。我希望澄清它？ – Vinzent

剛剛在純JavaScript

var sources = {"john": ["A","B"],"mike": ["123","234","345"],"doe": ["abc","cde"],"ann": {"abc": ["yxc","xcv","cvb"],"bcd": ["poi","iuz","uzt"]}}; 
 
    var destination_level_0 = {"FinalA": ["Element1","Element2","Element1","Element2","Element2"],"FinalB": ["Element2","Element2","Element2","Element1"]}; 
 
    var destination_level_1 = {"Element1": ["john","ann","john","john","doe","mike"],"Element2": ["ann","mike","ann","doe","doe","doe","ann"],"Element3": ["ann","doe","ann"]}; 
 
    
 
    var final = {}; 
 
    for(var key in destination_level_0){ 
 
     var preFinal = []; 
 
     var elems = destination_level_0[key]; 
 
     for(var i in elems){ 
 
      var elem = elems[i]; 
 
      var names = destination_level_1[elem]; 
 
      for(var j in names){ 
 
       var name = names[j]; 
 
       var finalItem = sources[name]; 
 
       preFinal.push(finalItem); 
 
      } 
 
     } 
 
     final[key] = preFinal; 
 
    } 
 
    
 
    console.log(final); 
 
    console.log(JSON.stringify(final));

非常感謝你......我得到了它的工作 - 主要是：只有一件事：我怎麼能夠嵌套在上面的「陣列項目」內的最低級別？例如對不，看起來像這樣： FinalA - > john： {「FinalA」：[[「A」，「B」]，{「abc」：[「yxc」，「xcv」，「cvb」]，「bcd」：[「poi」，「iuz」，「uzt」]}，[「A」，「B」]，[「A」，「B」]，[「abc」，「cde」]，... 我確實需要元素來自嵌套在一個項目數組項目下的「來源」，例如FinalY - > Element1 - > john {「FinalA」：[[[「A」，「B」]，{「abc」：[「yxc」，「xcv」，「cvb」]，「bcd」：[ poi「，」iuz「，」uzt「]}，[」A「，」B「]，[」A「，」B「]]，[」abc「，」cde「]，任何想法？ – Vinzent

對不起，我沒有得到你的問題。你可以用你想要的輸出的例子來編輯你上面發佈的問題嗎？ – Karlen

我想我知道了 - 非常感謝您的幫助！ – Vinzent

地圖從0級=> 1級=>的項目級別2使用Array#.map內部Array#map（或lodash的_.map()）：

var level0 = {"FinalA": ["Element1","Element2","Element1","Element2","Element2"],"FinalB": ["Element2","Element2","Element2","Element1"]}; 
 
var level1 = {"Element1": ["john","ann","john","john","doe","mike"],"Element2": ["ann","mike","ann","doe","doe","doe","ann"],"Element3": ["ann","doe","ann"]}; 
 
var level2 = {"john": ["A","B"],"mike": ["123","234","345"],"doe": ["abc","cde"],"ann": {"abc": ["yxc","xcv","cvb"],"bcd": ["poi","iuz","uzt"]}} 
 
; 
 

 
var result = Object.keys(level0).reduce(function(r, key) { 
 
    r[key] = level0[key].map(function(element) { 
 
    return level1[element].map(function(item) { 
 
     return level2[item]; 
 
    }); 
 
    }) 
 
    
 
    return r; 
 
}, Object.create(null)); 
 

 
console.log(JSON.stringify(result));
