使用div作出一个模态框的效果

      在用模态框做一个弹出框时发现设置了模态框的无地址栏，无状态栏等设置后IE6可以办到，但是IE7里还是会显示地址栏，状态栏搞的我很郁闷，上网找到这个方法可以很好的解决！

异步调用：

var url ="validatelogin.action?cmd=goUpdate&formMap.type=modPW&formMap.moduleId=207&formMap.className=PwdCh";
                new Ajax.Request(url,{method: "post", onSuccess: function(transport) {
                    var retxt = transport.responseText.strip();
                    sAlert(retxt);
                }});
