如何从对象数组中删除项目？

    var arr = [
        {
        id: 2,
        date: '2010-10-03',
        des: 'goodday'},
    {
        id: 3,
        date: '2011-02-13',
        des: 'badday'},
    {
        id: 4,
        date: '2011-04-03',
        des: 'niceday'}
    ];

    for(var i=0; i<arr.length; i++){
        if(arr[i].id == 3){
            arr.splice(i, 1);  //removes 1 element at position i 
            break;
        }
    }

console.log(arr);  
//should give you 
//                      var arr = [
//                               {id:2,date:'2010-10-03',des:'goodday'},
//                               {id:4,date:'2011-04-03',des:'niceday'}
//                          ];

arr.splice(1,1);

arr[1]

arr[2]

// Your array
var oArr = [
    {id:2,date:'2010-10-03',des:'goodday'},
    {id:3,date:'2011-02-13',des:'badday'},
    {id:4,date:'2011-04-03',des:'niceday'}
];

// Array with the values to be removed, here I have taken the id
var oArrToRemove = [2] 

// Using filter method to delete the object
var oNewArr = arr.filter(ele => { return remArr.indexOf(ele.id) === -1})

// The oNewArray will be as follows
oNewArr = [
    {id:3,date:'2011-02-13',des:'badday'},
    {id:4,date:'2011-04-03',des:'niceday'}
];
