how can i set the property in empty object using for loop?

Question

this is my data which i am getting through the form.

var subject  = {
"items":[
    {
    "EmailType":"INVITATION",
    "name":"INVITATION",
    "subject":"Welcome to Transcendental Meditation India",
    "from":"noreply.globalwebsite@tm.org",
    "body":"hello",
    "active":true,
    "confidential":false,
    "numberOfDaysToWait":1,
    "sequentialOrder":3
    },
    {
    "EmailType":"Create New",
    "name":"sweeeee",
    "subject":"eeee",
    "from":"swa@mail.com",
    "body":"hello2",
    "active":false,
    "confidential":true,
    "numberOfDaysToWait":1,
    "sequentialOrder":2
    }
    ]}

I am using the loop to create another array of object which looks like this after modifying subject.

"Catitems": [
    {
      "template": {
        "name": "Series 1 email",
        "from": "TEAMGMG",
        "subject": "GROUP2 - SERIES1 - EMAIL",
        "body": "<html><body><strong>My test email</strong></body></html>",
        "confidential": true,
        "active": true
      },
      "sequentialOrder": 1,
      "numberOfDaysToWait": 0,
    }, {
      "template": {
        "name": "Series 2 email",
        "from": "TEAMGMG",
        "subject": "GROUP2 - SERIES2 - EMAIL",
        "body": "<html><body><strong>My test email2</strong></body></html>",
        "confidential": true,
        "active": true
      },
      "sequentialOrder": 2,
      "numberOfDaysToWait": 10,
    }
  ]

I Have tried to manipulate the Subject with this loop but can not be able to set the property.

var Catitems={};
for(var i=0; i<subject.items.length ; i++){
  Catitems[i]["name"]= subject.items[i].EmailType
}
console.log(item);

Answer 1

Your Catitems is declared as object , when it should be declared as an array :

var Catitems=[];
for(var i=0; i<sobject.items.length ; i++){
    var tempObj = {
        "template":{} //must set this otherwise some other error
    };
    tempObj["template"]["name"] = sobject.items[i].EmailType
    //tempObj["template"]["somethingElse"] = sobject.items[i].somethingElse

    Catitems.push(tempObj);
}
//console.log(item); //not defined btw
console.log(Catitems);

If you want to modify each one of the element in the array, you can use Array.map to map each item in the array to a new obj structure.

 var subject = { "items": [{ "EmailType": "INVITATION", "name": "INVITATION", "subject": "Welcome to Transcendental Meditation India", "from": "noreply.globalwebsite@tm.org", "body": "hello", "active": true, "confidential": false, "numberOfDaysToWait": 1, "sequentialOrder": 3 }, { "EmailType": "Create New", "name": "sweeeee", "subject": "eeee", "from": "swa@mail.com", "body": "hello2", "active": false, "confidential": true, "numberOfDaysToWait": 1, "sequentialOrder": 2 } ] } const CartItems = subject.items.map((item) => { return { name: item.EmailType, template: { name: item.EmailType, from: item.from, subject: item.subject, body: item.body, confidential: item.confidential, active: item.active }, sequentialOrder: item.sequentialOrder, numberOfDaysToWait: item.numberOfDaysToWait, }; }); console.log(CartItems)
