我正在制作一个简单的活动日历。当我第一次加载页面时，日历加载。然后，当我点击下一个或上一个时，它会将我带到下个月，但事件不会加载，月份标题不会更改，但会绘制正确的日历。我尝试从代码中获取我的事件脚本并将其放在控制ajax的函数中，但它不起作用。
以下是该页面的链接。 http://hartslogmuseum.com/bookhjr10/cal/final/ajcal3.php （是的，现在很难看）
有人能指出我正确的方向吗？谢谢。 这是代码。

您发布的代码未包含定义'$ month_name'的部分。该问题（很可能）与$ month_name没有正确设置有关。期待做类似的事情：
function draw_calendar($month,$year,$events = array()){
//set month name
$month_name = date("F", mktime(0, 0, 0, $month, 10));
//rest of your code

好的，我是jQuery和PHP的新手，但是我注意到了一些事情：
1）每次在调用"calendar_wrapper"或getNextMonth()后重新加载页面时，您都会创建第二个getPrevMonth() div。我不熟悉Ajax.Updater，Google表明它是Prototype.js，而不是jQuery，对吧？为了解决这个问题，我的猜测是你没有在Ajax.Updater中使用DOM语法引用calendar_wrapper。在"#calendar_wrapper" / Ajax.Updater内的getNextMonth()来电中尝试getPrevMonth()。如果您正在寻找与Ajax.Updater等效的jQuery，请查看$.ajax()。
2）您的“日期设置”部分让您的变量在GET全局数组（$_GET['month']）中查找，但您的AJAX更新程序正在通过POST发送数据。这可能是您的PHP脚本正确返回数据但不能正确更新变量的原因。
3）我的代码中没有看到任何内容来选择月/年元素，并使用从getPrevMonth()或getNextMonth()收到的数据进行更新。为此，您可能需要一个事件处理程序来使用新数据更新元素。例如，我给你的第一个h2头一个id，然后让jQuery用你从PHP收到的数据更新h2里面的$.text()。但是，当您读取更新的$month变量时，看起来您正在寻求让PHP回显更新的HTML。如果是这种情况，希望解析制作两个calendar_wrapper div的页面将解决它。
