一段自己不錯的Js循環層顯示或隱藏代碼

  //顯示或隱藏層
    function Heid(id) {
        var divList = document.getElementById("globallinks").getElementsByTagName("div");
        for (var i = 0; i < divList.length; i++) {
            if (divList[i].id == id) {
                divList[i].style.display = "";
            } else {
            divList[i].style.display = "none";
            }
        }
    }
