vue 数组1 {"typeid":1,2,"typeid":2} 数组2 [{"typeid":1,"name":"A"},{"typeid":2,"name":"B"} ] 将数组1里面的1,2 替换成A,B

在Vue中，可以使用`map`方法来遍历数组1，并根据每个对象的`typeid`属性来替换成对应的名称。以下是一个示例代码：

const arr1 = [{"typeid":1},{"typeid":2}];
const arr2 = [{"typeid":1,"name":"A"},{"typeid":2,"name":"B"}];

const result = arr1.map(item => {
  const { typeid } = item;
  const replacement = arr2.find(obj => obj.typeid === typeid);
  return { ...item, ...replacement };
});

console.log(result);  // 输出：[{"typeid":1,"name":"A"},{"typeid":2,"name":"B"}]
