删除Java脚本中的子数组项 [英] Remove Sub Array Item in Javascript

问题描述

如何从JavaScript/jQuery中id = 2的以下数组中删除整个子数组项?

How would I remove the whole sub array item from the following array where id = 2 in JavaScript/jQuery?

arr = [{
    "id": 1,
    "name": "Steve"
},{
    "id": 2,
    "name": "Martin"
},{
    "id": 3,
    "name": "Short"
}]

我不确定在这种情况下如何使用grep或splice.

I am not sure how to use grep or splice in this situation.

我想要的输出将是:

newArr = [{
    "id": 1,
    "name": "Steve"
},{
    "id": 3,
    "name": "Short"
}]

推荐答案

尝试使用

Try to use Array.prototype.filter at this context,

var arr = [ {"id":1,"name":"Steve"} , {"id":2,"name":"Martin"} , {"id":3,"name":"Short"} ];
var newArr = arr.filter(function(itm){
  return itm.id !== 2;
});
