    I've modified your script to work with jQuery, if you wish to do so.

    $(document).ready(function(){
        //To add a task when the user hits the return key
        $('#task-text').keydown(function(evt){
              if(evt.keyCode == 13)
              {
                 add_task($(this), evt);
              }
        });
        //To add a task when the user clicks on the submit button
        $("#add-task").click(function(evt){
            add_task($("#task-text"),evt);
        });
    });
    
    function add_task(textBox, evt){
      evt.preventDefault();
      var taskText = textBox.val();
      $("
  • ").text(taskText).appendTo("#tasks"); textBox.val(""); };
