javascript - js中怎么用最简单的方法找到对象数组中的对应值？

Question

如下面的数组，如果我拿到一个值是3，我怎么最简单的找到他对应的{id:3,name:'挂号'}中“挂号”

OperationTypeList:[
                    {id:0,name:'门诊充值'},
                    {id:1,name:'住院押金'},
                    {id:2,name:'划价缴费'},
                    {id:3,name:'挂号'},
                    {id:4,name:'核酸开单'},
                ]

Answer 1

使用 Array.prototype.find()

var OperationTypeList = [
    {id:0,name:'门诊充值'},
    {id:1,name:'住院押金'},
    {id:2,name:'划价缴费'},
    {id:3,name:'挂号'},
    {id:4,name:'核酸开单'},
]

var result = OperationTypeList.find(item => item.id === 3)
console.log(result.name)
// log => '挂号'
