php事件日历。 javascript按钮不会按

我一直在关注如何制作php日历的一个非常讨厌的教程。我已经到了最后一点，但我有一个按钮来显示某些日期的数据库中的信息，当我点击它没有任何反应。它应该显示一个显示信息的框。没有错误信息或任何事情，当你点击它时什么都没有发生。也许我做了一个简单的错误？有没有人有任何想法？我需要完成今晚:( 感谢php事件日历。 javascript按钮不会按

它可能是由于你的CSS文件名#eventcontrol不同于show_calendar ... 即时通讯仍然有问题我只是想知道你是否有你的工作？？ – user2108423

不会在您的代码过于紧密的样子，我注意到您在字符串传递到你的（过时的和危险的），MySQL的功能

$db_host = "localhost"; 
$db_username = "root"; 
$db_pass = "heyman"; 
$db_name = "ecalandar"; 
$conn = mysql_connect($db_host, $db_username,$db_pass) or die ("could not connect to mysql"); 
mysql_select_db($db_name) or die ("no database");

你应该做的PDO一些阅读/ mysqli

您是否尝试进行建议更改？ 'mysql_select_db（$ db_name）'etc？ –

嘿耶是谢谢，没有改变:(Im难倒！ – user1801197
