Jquery 通知事件触发两次

Question

我刚开始使用 grutter 通知插件并遇到奇怪的行为。我在页面加载时显示通知，出于某种原因，相同的消息出现了两次。如果有人可以检查我的代码并突出显示我忽略的任何错误，我将不胜感激。该插件的链接是：http://boedesign.com/blog/2009/07/11/growl-for-jquery-gritter/。非常感谢。

            <?php

                mysql_select_db($database_domain, $domain); 
                $query1 = "SELECT * FROM messages WHERE to_user = '$_SESSION[kt_name_usr]' AND `read` = 1";

                // There was a result
                // now check if there were any records.
                    if (mysql_num_rows($result1) >0) {

                } else { 

                    echo 'There are no new system or site messages to display.';

           </div>

          </div>

          <div id="testid" style="display:none;"></div>

解决方案：

<script type="text/javascript">
       $(function () {
            var newmsg = <?php echo json_encode($messages1) ?>;
            $.gritter.add({title: 'New Message', text: newmsg, time: 4000, sticky: false});
    });
</script>

Answer 1

只需注释掉这一行，

echo "You have" . "  " . "<span class='yourstyle'>" . $totalRows1 . "</span>" . " " . "new message(s). Please go to the message area in your control panel.";

Answer 2

stopImmediatePropagation() 解决了同样的问题

尝试使用以下代码

    <script type="text/javascript">
       $(function (event) {
            event.stopImmediatePropagation();
            var newmsg = <?php echo json_encode($messages1) ?>;
            $.gritter.add({title: 'New Message', text: newmsg, time: 4000, sticky: false});
    });
</script>
