Time:2020-1-19

Encapsulate a function

function getColor() {
      var str = "#";
      //An array of hexadecimal values
      var arr = ["0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "a", "b", "c", "d", "e", "f"];
      for (var i = 0; i < 6; i++) {
        //Each random number generated is an index, which finds the corresponding values in the array and splices them together
        var num = parseInt(Math.random() * 16);
        str += arr[num];
      }
      return str;
}
