在关联数组中添加数据

Question

How come when i try to add something into the "Enfant" array that i have initialized it gives me a number. In this case it gives me 3 when i add a string into it.

    var person=[];

function addPerson(n,a){
    person.push({ "Name" : n, "Age" : a, "Kid" : []});

}

addPerson("Julie",100); addPerson("Sarah",83);

function addKid(parentName,kidName){

    for(var i=0;i<person.length;i++){
        if (parentName== person[i].Name){
            person[i].Kid=person.push(kidName);
    }   
  }
}

addKid("Julie","Sarah");
print(person[0].Kid); //<--- gives me 3

Answer 1

Array.push返回推送后数组中元素的数量，这是您要分配给person[i].Kid

Answer 2

You should do person[i].Kid.push instead.

function addKid(parentName,kidName){

    for(var i=0;i<person.length;i++){
        if (parentName== person[i].Name){
            person[i].Kid.push(kidName);
    }   
  }
}
