Javascript 获取请求未加载PHP脚本
每当用户从“分配给组”选项列表中进行新选择时，我都会尝试更新我的“分配给用户”选项列表。我在使用ajax函数执行此操作时遇到问题，但这不起作用，所以我尝试使用此获取方法。我可能只是不正确地使用了它，但在这两种方法中，它都没有真正尝试重定向到ticket_details.php页面（调用它的是同一个页面）。我已经验证了这一点，因为我让它在加载页面时回显警报。当第一次进入页面或按下表单上的submit按钮时（当前不做任何事情），警报将熄灭，因此我知道每当加载页面时，警报都会响起。我不知道这是否是我的代码的问题，或者我缺少一些设置，或者xxamp不喜欢它 另外，我知道SQL很容易受到注入的攻击，稍后我将把它改成更安全的Javascript 获取请求未加载PHP脚本,javascript,php,ajax,post,fetch,Javascript,Php,Ajax,Post,Fetch,每当用户从“分配给组”选项列表中进行新选择时，我都会尝试更新我的“分配给用户”选项列表。我在使用ajax函数执行此操作时遇到问题，但这不起作用，所以我尝试使用此获取方法。我可能只是不正确地使用了它，但在这两种方法中，它都没有真正尝试重定向到ticket_details.php页面（调用它的是同一个页面）。我已经验证了这一点，因为我让它在加载页面时回显警报。当第一次进入页面或按下表单上的submit按钮时（当前不做任何事情），警报将熄灭，因此我知道每当加载页面时，警报都会响起。我不知道这是否是我的
