想要从数组中拼接一个元素

Question

I want to splice an item from an array, my array is like,

array=[{'PatientID':545, 'Name':jey, 'ref': d},
       {'PatientID':544, 'Name':tay, 'ref': dj},
       .... ] 

I wrote a code for splicing, but it does'nt work, Uncaught TypeError: item.PatientID.indexOf is not a function this error is occured

remove(id){
    var index = array.map(item=>{(item.PatientID).indexOf(id)})
....
}

How to resolve my issue?

Answer 1

To find the index based on the id

const findIndex = id => array.findIndex(i => i.id === id)

const index = findIndex('545')

To remove an item based on the id

const deleteItem = id =>{
    return array.filter(i => i.id !== id)
}

const newArray = deleteItem(545)

Mutating the array

const deleteItem = id =>{
    const index = array.indexOf(i => i.id === id)
    array.splice(index, 1)
}
