在视图层,定义一件按钮事件来触发“调用JS”的C#方法: 在逻辑层定义“调用JS”的C#方法,在方法调用JS:int a = await JS.InvokeAsync<int>("MyApp.simpleSum",2,3) //MyApp.jsvarMyApp = MyApp ||{}; MyApp.simpleSum=function (a, b) {returna...
await calltheeventmethod StateHasChanged(); 所以下面的代码不会按预期执行: void async ButtonClick(MouseEventArgs e) { await Task.Delay(2000); UpdateADisplayProperty(); } 注意:这里的示例代码返回的是void而不是task。返回void的用法通常在winform等程序中出现,但是缺点是捕获不到异常等信息。 DisplayPrope...
await JSRuntime.InvokeAsync<string>("convertArray", _quoteArray); _convertedText = new MarkupString(text); StateHasChanged(); } } IJSRuntime 要使用 IJSRuntime 抽象,请采用以下任何一种方法: 将IJSRuntime 抽象注入 Razor 组件(.razor):
public EventCallback<string> OnSearch { get; set; } private string searchTerm = ""; private async Task SubmitSearch() { await OnSearch.InvokeAsync(searchTerm); } } 该组件包含一个搜索栏和一个用于执行搜索的按钮。 Blazor 允许在同一文件中使用 C# 代码动态生成 HTML,从而提供了极大的灵活性。
