Question

Ways to programmatically append data to an object using JavaScript

My dilemma involves an object:

var myObject={};

accompanied by a function that appends values to the object:

function appendData(id, name){
    //logic to validate id and name format, specify conditions for name being "John" and id being "I23423"
    myObject.id = name;
}

However, the output consistently appears as:

myObject{
    id="john"
}

What I actually desire is for the id to reflect whatever value the user inputs, resulting in:

myObject{
    I23423="John"
}

Any suggestions on what adjustments should be made?

Answer №1

If you're looking to achieve what you're asking for, you'll have to utilize square brackets `[]` on the object as if it were an array. I'm not entirely sure why this is necessary, but that's how it works.

function(id, name){
  var obj = {};
  //any other necessary tasks;
  obj[id] = name;
  return obj;
}
