Javascriptプロパティに複数の値を追加する

Question

プロパティ "Items"を追加したオブジェクトを定義しました。 .each関数内にそのデータがありますが、すべてのデータをコンマで追加するわけではありません。 1,2,3それだけでそれを切り替えます。私は間違って何をしていますか？

var data = {}; 
    $('.beauty').on('click', function(e){ 
     e.preventDefault(); 
     $('.selected').each(function(){ 
      data.Items = $(this).data('id'); 
     }); 
     $('.chosenTeam').each(function(){ 
      data.Team = $(this).data('team'); 
     }); 
     console.log(data);

データプロパティには複数の値が格納されません。その振る舞いが必要な場合、プロパティは配列またはオブジェクトを格納する必要があります。そして、そうであれば、新しい値を割り当てるだけではなく、わかっているように古い値を上書きするだけなので、その配列にデータをpush（たとえば）追加するか、addオブジェクトの新しいプロパティ

// Here, were have a basic object with a single property (users) 
 
// and that property has the ability to store multiple values 
 
// because it is intialized to store an array 
 
var myObject = {users : []}; 
 

 
// For demonstration, we'll append new values into 
 
// the array stored in the users property 
 

 
// This is just an example of a data source that we'll want to draw from 
 
// In reality, this could be any data structure 
 
var userArray = ["Mary", "Joe", "John", "Alice", "Judy", "Steve"]; 
 

 
userArray.forEach(function(user){ 
 
    // The most important thing is to note that we are not trying to 
 
    // set the users property equal to anything (that would wipe out 
 
    // its old value in favor of the new value). We are appending new 
 
    // data into the object that the property is storing. 
 
    myObject.users.push(user); 
 
}); 
 

 

 
console.log(myObject.users); 
 

 
// Now, if I want to change one of the values stored in the users 
 
// property, I wouldn't just set the users property equal to that 
 
// new value because that would wipe out the entire array currently 
 
// stored there. We need to updated one of the values in the data 
 
// structure that is stored in the property: 
 
myObject.users[3] = "Scott"; // Change the 4th user to "Scott" 
 
console.log(myObject.users);
