我正在使用asp.net core 3.1开发blazor客户端项目,并希望使用code-behind类。我找到了一个处理此主题的示例,但我认为它已过时且与客户端blazor无关。 以下是一个示例: @functions { [Parameter] string Id { get; set; } string PageTitle { get; set; } Book CurrentBook { get; set; } protected overri...
于是需要将script部分代码放置在外部,此时有两种方案,一个是放在wwwroot/js目录下,然后在wwwroot/index.html中引入,还有一种是使用并置的js文件,这种方式是所谓的"CodeBehind",因为更利于组织代码,这里我们使用并置的js文件。 创建一个HomePageWeb.razor.js文件,将script部分代码放置在其中,然后在HomePageWeb.razor中引...

CodeBehind中引入组件 varapp =newVue({ el:'#vue-app', data: { message:'Hello Vue!', showDialog:false, input:'text message from vue'} }) 运行效果如下: JavaScript和原生代码的交互 Blazor组件中的代码可以通过注入IJSRuntime来调用JavaScript代码,JavaScript代码可以通过调用DotNet.invokeMethodAsync来调用C#...
in code-behind classes, it is written much differently and at first glance may not be obvious. To use dependency injection in a code-behind file we'll use the[Inject]attribute and apply it to a property of the type we would like to inject, ex:[Inject] MyType MyProp { get; set; }...
The value of this Boolean property is set in the code behind (.cshtml.cs) page.The City dropdown list inside the form is binding to our Cities collection in the database with the help of cityList variable. The cityList will be populated as the application boots up....
Injecting web content inside a WPF app does not need to be a one-way street—the host app and the web content caninteract. The WPF host can listen in on lifecycle events raised by WebView2 and inject JavaScript code into WebView2 controls at runtime. One can also enable communications ...
