我有2个arrays in Angular 2我想根据一个键值合并它们。
数组1：
[{"columnId":1,"type":"value 1"},{"columnId":2,"type":"value 2"}]
数组2：
[{"columnId":1,"field":"field 1"},{"columnId":2,"field":"field 2"}]
所以我想要最终结果为
[{"columnId":1,"field":"field 1","type":"value 1"},{"columnId":2,"field":"field 2","type":"value 2"}]
这应该做你想要的：
const arr1 = [{"columnId":1,"type":"value 1"},{"columnId":2,"type":"value 2"}];
const arr2 = [{"columnId":1,"field":"field 1"},{"columnId":2,"field":"field 2"}];
const result = arr1.map(val => {
return Object.assign({}, val, arr2.filter(v => v.columnId === val.columnId)[0]);
});
console.log(result);
// [{"columnId":1,"field":"field 1","type":"value 1"},{"columnId":2,"field":"field 2","type":"value 2"}]
