at first I thought of indexOf (), but the usage on the Internet is an one-dimensional array. What if the array contains multiple objects?
array:[
{
id:1,
name:"A"
},
{
id:2,
name:"B"
},
{
id:3,
name:"B"
}
]
console.log(this.array.id.indexOf(2)); //your array is not a two-dimensional array, it is an array object, and it still belongs to an one-dimensional array
you can use findIndex to find subscripts
var fid = 2
array.findIndex(i=>i.id==fid);//1just modify your last sentence
console.log(this.array.map(o=>o.id).indexOf(2)) console.log (this.array.indexOf ({id:2,name:'B'}));
