很抱歉,如果有这样的主题,但我没有找到解决我问题的方法。所以,让我们去...... =)(我开始学习php)。
这是活动日历,它将是WP的小部件。它需要处理onclick事件。所有代码都写在一个文件中(这是插件)。在小部件(右侧边栏)中,我编写phpcode(用于测试),我调用这个函数。 http://herytire.esy.es/calendar 你可以推动' 2'或者' 5'日期,mysql中有这些日期的数据。 一切正常,但我从未在wordpress中使用php,并且在使用此代码时遇到问题。
问题是:
当我在简单的html页面中使用此代码时,您可以在上面的链接中看到它,一切正常,我得到我点击的一天的结果,但在wp,alert(for error)
,返回undefined
。两天我试图解决这个问题,但没有。我希望有人可以帮助我..!

答案 0 :(得分:0)
因为您的alert()
需要参数。
试试这个:
alert('An error has occurred.');
