javascript - 如何组合两个在Javascript中具有相同值的数组

Question

我有数组

 var array1 = [
    {"id" : 1,"val1" : 1,"val2": 1},
    {"id" : 2,"val1" : 2,"val2": 1},
    {"id" : 3,"val1" : 0,"val2": 0}
 ];

 var array2 = [
    {"id" : 1,"val1" : 1,"val3": 1},
    {"id" : 2,"val3": 1},
    {"id" : 3,"val3": 0}
 ];

我希望输出是这样的

 var array3 = [
   {"id" : 1,"val1" : 1,"val2": 1, "val3" : 1},
   {"id" : 2,"val1" : 2, "val3" : 1},
   {"id" : 3,"val1" : 0, "val3" : 0}
 ];

有没有简单的(r)快捷方式？谢谢!

Answer 1

您可以使用.map() , Object.assign()

var array3 = array1.map(function(o, i) {
               return Object.assign({}, array2[i], o)
             })
