Javascript使用filter()删除嵌套数组元素

Question

我有下面的对象，并想要删除元素("virAddrSeq"; "345")。

var state={
"todos": [
{
"accountNo": "50190000",
"name": "Sarkar",
"vpainfo": [
{
"virAddrSeq": "345"
},
{
"virAddrSeq": "34775"
}
]
}
]
}

我已经尝试了下面的方法，但没有删除元素得到所有的记录。

const newObj = Object.assign({}, state, {
todos: state.todos.filter(todoObj => (todoObj.vpainfo.filter(({virAddrSeq}) => (virAddrSeq != "345"))))
})
console.log(newObj)

Answer 1

var state = {
"todos": [{
"accountNo": "50190000",
"name": "Sarkar",
"vpainfo": [{
"virAddrSeq": "345"
},
{
"virAddrSeq": "34775"
}
]
}]
}
console.log(
state.todos.map(todo => ({...todo, vpainfo: todo.vpainfo.filter(({virAddrSeq}) => virAddrSeq!= 345)}))
)

var state = {
"todos": [{
"accountNo": "50190000",
"name": "Sarkar",
"vpainfo": [{
"virAddrSeq": "345"
},
{
"virAddrSeq": "34775"
}
]
}]
}
for (const s of state.todos) {
let findKey =s.vpainfo.find(x => x.virAddrSeq == '345')
let index = s.vpainfo.indexOf(findKey)
if(findKey && index > -1) s.vpainfo.splice(index,1)
}
console.log(state)
