使用这个例子：http ://www.w3schools.com/php/php_ajax_database.asp 我已经建立了一个从数据库回显的表。
我现在正在尝试在表上启动数据表插件，一切都设置正确，但它不会工作。我试图在 html 和 php 页面中启动数据表，但似乎都不起作用。
我在合并这个例子时同样有同样的问题：http: //davidwalsh.name/animated-ajax-jquery
是否是第一个示例中的这一点导致问题，因为页面已经在 xmlhttp.open 和 xmlhttp.send() 之前加载；已发送。
xmlhttp.open("GET","getuser.php?username="+username+"&year="+str,true);
xmlhttp.send();
