如何使用javascript更改db值？

我想用javascript更改一些db值我有一个命令列表，我选择了它们并想更改一些ID，但它不起作用需要帮助这里是我的屏幕截图

但当我选择用户并继续更改用户时，它在这里不起作用

这是我的密码

下面是每个按钮的复选框和型号代码 操作按钮（更改ot）

控制器代码

 public function confirmOrder($id, $sendToUnapprove = true, $selectedSeller = null , $selectedOrdertaker = null){

        if(Auth::user()->role <= 3 && $sendToUnapprove != true &&  
            $selectedSeller == null && $selectedOrdertaker != null){
            Order::where('id' , $id)->update(['user_id' => $selectedOrdertaker, 'ot_id' => $selectedOrdertaker]);

        }
        else if(Auth::user()->role <= 3 && $sendToUnapprove != true){
            Order::where('id' , $id)->update(['is_confirmed_seller' => Auth::id(), 'selected_seller' => $selectedSeller]);

        }
}

由于您使用jQuery，您可能需要查看$.ajax（）来调用API，该API将更新服务器上的数据库。您好，

Change ot

正在提交您的表单，正如您所做的那样

onclick=”“

。但是，在此之前，您还没有根据您的代码为

输入ot

赋值。当您在modal中更改selectbox时，该值将被赋值。但在此之前，只有您的表单会被提交。另外，当您单击

订购者确认时会发生什么情况？
