javascript - 合并两个 json 数组并推送项目值

Question

我有以下 json 数组:

数组1:

fruits1 = [{"fruit":"banana","amount":"2","color":"yellow"},{"fruit":"apple","amount":"5","color":"red"},{"fruit":"kiwi","amount":"1","color":"green"}]

数组2:

fruits2 = [{"fruit":"banana","sold":"1","stock":"3"},{"fruit":"apple","sold":"3","stock":"5"},{"fruit":"kiwi","sold":"2","stock":"3"}]

我只想得到一个数组，它根据水果值合并结果，如下所示:

fruits = [{"fruit":"banana","amount":"2","color":"yellow","sold":"1","stock":"3"},{"fruit":"apple","amount":"5","color":"red","sold":"3","stock":"5"},{"fruit":"kiwi","amount":"1","color":"green","sold":"2","stock":"3"}]

我需要做类似的事情

    foreach item.fruit where fruit = fruit from initial array 
    fruits.push item

有什么想法吗？

Answer 1

尝试这个逻辑:

 function merge_options(obj1,obj2){
   var obj3 = {};
   for (var attrname in obj1) { obj3[attrname] = obj1[attrname]; }
   for (var attrname in obj2) { obj3[attrname] = obj2[attrname]; }
   return obj3;
 }


 var obj1 = [];
 for (var i = 0; i <  fruits1.length ; i++) { 
     obj1[fruits1[i].fruit] = fruits1[i]; 
 }

 var obj2 = []; 
 for (var i = 0; i <  fruits2.length ; i++) { 
     obj2[fruits2[i].fruit] = fruits2[i]; 
 }

 var fruits = []
 for (var key in obj1) { 
   fruits.push(merge_options(obj1[key],obj2[key]));
 }

  console.log(fruits);
