JS:

  function click_a(divDisplay) {
                if (document.getElementById(divDisplay).style.display != "block") {  //直接引用对象的style属性
                    document.getElementById(divDisplay).style.display = "block";
                }
                else {
                    document.getElementById(divDisplay).style.display = "none";
                }
            }

JQuery:

  $(document).ready(function () {$("#li01").click(function ()

{  if ($(‘#menu1‘).css(‘display‘) != "block")   $("#menu1").show(2000);          //$(‘#menu1‘).css(‘display‘)  获取CSS的属性值

  else    $("#menu1").hide(2000);

                  });});
