Objects in Arrays: Unexpected String

Question

I am getting the above error in this code:

var inputs = {
    $("<input>").attr({"type":"hidden","name":"collegeID"}).val(collegeID),
    $("<input>").attr({"type":"hidden","name":"collegeID"}).val(collegeID),
    $("<input>").attr({"type":"hidden","name":"collegeID"}).val(collegeID),
    $("<input>").attr({"type":"hidden","name":"collegeID"}).val(collegeID),
    $("<input>").attr({"type":"hidden","name":"collegeID"}).val(collegeID),
    $("<input>").attr({"type":"hidden","name":"collegeID"}).val(collegeID) 
}

This looks pretty valid to me. I want to .append() the variable on to a div and I dont want to have to create a bunch of different variables to do that.

You use square brackets ([]) for array literals. Curly brackets are for objects meaning it expects key-value pairs. — Lennholm

Your creating an object literal from a list of objects. I guess you want inputs = [] to create an array? — Phil Cooper

@MikaelLennholm Thanks! That worked straight away lol, I didn't know that in Javascript. — Chud37

inputs need to be an Array. use [] instead of {}

var collegeID = "";
var inputs = [
  $("<input>").attr({
    "type": "hidden",
    "name": "collegeID"
  }).val(collegeID),
  $("<input>").attr({
    "type": "hidden",
    "name": "collegeID"
  }).val(collegeID),
  $("<input>").attr({
    "type": "hidden",
    "name": "collegeID"
  }).val(collegeID),
  $("<input>").attr({
    "type": "hidden",
    "name": "collegeID"
  }).val(collegeID),
  $("<input>").attr({
    "type": "hidden",
    "name": "collegeID"
  }).val(collegeID),
  $("<input>").attr({
    "type": "hidden",
    "name": "collegeID"
  }).val(collegeID)
]

console.log(JSON.stringify(inputs));
