所以在过去的几天里，我一直在努力让这个页面正常工作。就数据库操作而言，它就像一个魅力。问题是，它显然没有击中我的javascript函数以重定向回自身。相反，它将显示一个大部分空白的页面，url中没有$\u GET变量，这让我相信问题实际上是在我的php函数中，而不是在我的javascript函数中PHP Javascript交互,javascript,php,mysql,html,Javascript,Php,Mysql,Html,所以在过去的几天里，我一直在努力让这个页面正常工作。就数据库操作而言，它就像一个魅力。问题是，它显然没有击中我的javascript函数以重定向回自身。相反，它将显示一个大部分空白的页面，url中没有$\u GET变量，这让我相信问题实际上是在我的php函数中，而不是在我的javascript函数中 function edit_player() { try{ if( isset( $_GET['player_id'] ) ) { if( isset( $_GET
