I have a problem with this code:

function calculate() {
  var input = document.getElementById("input").value;
  var x = input;
  for (var i = input; i > 1; i--) {
    x += i;
  }
  var j = 1;
  var k = 1;
  var number = 1;
  var output;
  while (k < x) {
    output = number.toString() + " ";
    number += 1;
    if (number = j) {
      output += "\n";
      j = 1;
      k++;
    }
  }
  document.getElementById("output").innerHTML = output;
}

<input id="input" type="number" />
<button onclick="calculate()">Calculate</button><br/>
<span id="output"></span>

It always returns 1. Can someone please help me?
