Append var to div

Question

I made a Roulette game, but now I´m struggeling to use an int in the Append method. I want to use the var number as the paragraph of the appended div. Thanks in advance!

if (Red == true) {

  Red = false;
  var randnum = Math.floor((Math.random() * 4) + 1);
  var number;
  switch (randnum) {
    case 1:
      number = 1;
      break;
    case 2:
      number = 3;
      break;
    case 3:
      number = 5;
      break;
    case 4:
      number = 7;
      break;

  }


$("#WheelList").append("<li><div class='red'><center>'number'</center></div></li>");

Simply concatenate the number with string using + symbol.

$("#WheelList").append("<li><div class='red'><center>" + number + "</center></div></li>"); 
//                                          ---------^^^^^----^^^^^^----

Like this.In javascript + operator is used for concatenation.

if (Red == true) {

  Red = false;
  var randnum = Math.floor((Math.random() * 4) + 1);
  var number;
  switch (randnum) {
    case 1:
      number = 1;
      break;
    case 2:
      number = 3;
      break;
    case 3:
      number = 5;
      break;
    case 4:
      number = 7;
      break;

  }


$("#WheelList").append("<li><div class='red'><center>"+number+"</center></div></li>");
