MVC c#应用程序错误显示messagebox.show

本文关键字:messagebox show 显示 错误 应用程序 MVC | 更新日期: 2023-09-27 18:10:06

在Visual Studio 2015中运行我的MVC4应用程序时,她的常规运行和运行一切都在浏览器中,ultilizo MessageBox。显示在中间的代码,看到在某些地方使用相同的,通常没有问题。

我在开发框架4.6中使用的,也就是说我把它安装在我的机器上,这将是服务器强制执行,我的IIS 7和我的userappool只有框架v4.0.30319。

我不需要使用messageBox,但这是唯一的解决方案,我发现,有另一个选项显示消息的用户?

当你打开应用程序在浏览器中打开正常点击按钮执行操作和生成消息框它生成下面的错误:

MVC c#应用程序错误显示messagebox.show

根据到目前为止的评论线程…

如果你只想从控制器向视图发送"消息",你可以将其设置为模型的属性:

someModel.SomeProperty = "Some Message";

或者,在最坏的情况下,作为ViewData:

的一部分
ViewData["SomeProperty"] = "Some Message";

然后在视图中显示它。理想情况下,这是比alert()更优雅的东西。您可以将其包含在标记中:

@if(!string.IsNullOrEmpty(Model.SomeProperty)) {
    <div id="message">@Model.SomeProperty</div>
}

然后你可以应用任何样式或效果,你想要的div。但是,如果确实想要使用alert(),则可以使用相同的方法:

@if(!string.IsNullOrEmpty(Model.SomeProperty)) {
    <script type="text/javascript">
        alert('@Model.SomeProperty');
    </script>
}

(当将JavaScript代码放入Razor块中时,您可能需要明智地使用<text></text>标记。有时语法会混淆呈现引擎。)
