Filter eligible values from the object array

Traverse the keys in the current array to get the current array object that contains the same key in another array

const arr = [1,2,3,4,5,6,7]
const list = [
	{
    
    openId: 1, timelineId: 1, showNo: 1, uid: 1},
	{
    
    openId: 2, timelineId: 1, showNo: 1, uid: 1},
	{
    
    openId: 9, timelineId: 1, showNo: 1, uid: 1},
	{
    
    openId: 4, timelineId: 1, showNo: 1, uid: 1},
	{
    
    openId: 5, timelineId: 1, showNo: 1, uid: 1}
]
const params = list.filter(item=> arr.indexOf(item.openId) > -1)
console.log(params)
