如何将php变量传入ajax success函数并分配给JavaScript变量

我想访问前端ajax成功回调函数中的后端php变量。怎么做？ 我的代码php代码

    if($_POST["action"] == 'check_ot_count')

            $totaltime +=explode_time($time_val); // this fucntion will convert all hh:mm to seconds
         }
          $tablecount = second_to_hhmm($totaltime);
          $approval = GetApprovedOt($connect,$_SESSION["dept_Id"],$month);

          if($approval == ':00'){

我想在不同的条件下得到4种类型的警报框，前两个警报框工作，但最后2个警报不工作，因为php变量没有正确地进入ajax成功回调函数，我如何解决上述问题？

您在POST请求中声明了一个变量

$temp

。因此，注入这个变量基本上已经太晚了——这需要在构建资源（例如包含JS的index.html）的初始GET请求上完成

你有两个选择

在为内容提供服务时注入令牌。因为您不应该使用内联JS，所以可以包含一个包含令牌/日期的隐藏字段，以便在以后的POST请求中进行签入

通过单独的AJAX调用，在POST请求之前获取您的令牌/日期

---

常规：您不应该使用纯文本响应-特别是如果您使用JS处理它们。最好将您的响应编码为JSON，这样您就能够给出结构化的响应。请参阅json_encode（）。

现在，您正在从PHP脚本发送纯文本作为响应。您应该对此进行更改，以便返回正确的数据结构-否则，您将无法在客户端分离文本和变量值。做一个正确的JSON响应，返回一个具有正确密钥的对象，并在客户端相应地处理它。是的，兄弟，我正在寻找JSON方法来完成这项任务。谢谢同志任务完成了。。
