为什么数组中有未定义的？如何删除对象？

arr = [
  {id:1,name:'aaa'},
  {id:2,name:'bbb'},
  {id:3,name:'ccc'}
];

for(var item in arr){
  if(arr.hasOwnProperty(item)){
    if(arr[item].id === 2){
      delete(arr[item]);
      continue;
    }
  }
}

console.log(arr);

最佳答案

希望这是您想要做的：-

var arr = [
  {id:1,name:'aaa'},
  {id:2,name:'bbb'},
  {id:3,name:'ccc'}
];


arr = arr.filter(function(item){
  return item.id != 2;
});

console.log(arr)
