    I am appending li in a ul using the following code:

    for (var i = 1; i <= len; i++) {
    li = document.createElement(\'li\');

      If you are using jQuery, why don't you use it's benefits?

      adding

    • elements:

      $("
      • ").appendTo(root);

      removing all

    • elements:

      $(root).empty();

      deleting one

    • element:

      $("li:eq(3)",$(root)).remove();

      and if you are using raw js, you can use:

      document.getElementById("root").innerHTML = "";
