        $template->SetTag("content", $content);
        echo $template->Display();

    ?>

出于测试目的：
注释所有内容，直到程序在中开始
/*

*/
$content .="

然后改变：
$template->SetTag("content", $content);
echo $template->Display();

用于：
最后，内部的脚本标记写：
alert('Javascript is working');

我成功了，让程序运行起来。问题出在$template类中，而不是此代码中
干杯，PHP的HTML输出是什么？您可能会在那里找到错误。如果需要帮助，请发布控制台输出（chrome developer控制台）。同意Mooseman的观点，呈现HTML也会有所帮助。或者创建一个jsfiddle.just had this.Uncaught SyntaxError：如果您的javascript看起来不包含任何服务器端变量，则会出现意外标记。你不能把它放在一个单独的.js文件中吗？它只是检查在dropbown框中选择的值，所以真的应该有任何服务器端变量吗？
alert('Javascript is working');
