JavaScript method to sort drop-down list values_javascript skills

The example in this article describes how to use JavaScript to sort drop-down list values. Share it with everyone for your reference. The details are as follows:

function sortList(id) {
  var obj = document.getElementById("id");
  var values = new Array();
  for(var i = 0; i < obj.options.length; i++) {
    values.push(obj.options[i].innerHTML + "--xx--" + obj.options[i].value);
  }
  values = values.sort();
  for(var i = 0; i < values.length; i++) {
    valueArray = values[i].split('--xx--');
    obj.options[i].innerHTML = valueArray[0];
    obj.options[i].value = valueArray[1];
  }
}

I hope this article will be helpful to everyone’s JavaScript programming design.
