    function initialize() {
        var list = document.getElementById("list");
        if (Boolean(list)) {
            var script01 = document.createElement("script");
            var sdata = document.createAttribute("data");
            var script02 = document.createElement("script");
            var script03 = document.createElement("script");

            script01.type = "text/javascript";
            script01.id = "bdshare_js";

            script03.type = "text/javascript";
            script03.innerHTML = "    document.getElementById(\"bdshell_js\").src = \"\" + Math.ceil(new Date()/3600000);";
