标签上有一个标记，所以我根据它来回答）。我已经更新了上面答案中的代码，现在应该和你的兼容了。没有，因为我的代码使用prototypejs从数据库中获取信息。因此，我必须在noconflict模式下使用jquery。当我放入

$（'#messages_content'）.append（''+response['msg']+''）时而不是
$（'messages_content'）。innerHTML+=''+响应['msg']+''它不工作。即使我把它放在noconlict代码
jQuery（document）.ready（函数（$）{$（'#messages_content'）.append（''+response['msg']+''）；}）之间
但是如果你能将上面的原型代码转换成Jquery，我会很高兴将其置于noconflict模式并再次尝试。我已经编辑了代码，但仍然没有得到结果。请使用用户名cadnel和密码cadnel访问并登录。然后单击消息信封或登录后转到，在我添加了您给我的代码后检查演示
