我正在用 asp.net MVC 开发一个项目。现在我想在 ViewModel 中为“成功添加”的新值（按表单）制作弹出窗口。我应该使用 JSON ， AJAX 和 jquery 技术来做到这一点，但经过 1 天的尝试没有成功，我希望得到你的帮助。
我想收到弹出“成功消息”的表单称为“测量”。
这就是视图模型“测量”中的源代码
@model ePatient.Web.Models.MeasurementModels
@{
ViewBag.Title = "Register";
}
<script>
$(document).ready(function () {
$('.date').datepicker({dateFormat: "mm/dd/yy"});
});
</script>

我的问题是如何获得 JSON 值 success=true 并将其转换为警报弹出窗口（成功添加），通过单击“确定”重定向到某些操作。
先感谢您。
