精确统计网站访问量的程序中,主函数(最后调用的那个函数)怎么传参或者运行。

精确统计网站访问量的程序中,主函数(最后调用的那个函数)怎么传参或者运行。

代码是这样的/** * vlstat 浏览器统计脚本 */var statIdName = "vlstatId";var xmlHttp;/** * 设置cookieId */function setCookie(c_name, value, expiredays) {    var exdate = new Date();    exdate.setDate(exdate.getDate() + expiredays);    document.cookie = c_name + "=" + escape(value) + ((expiredays == null) ?
