问题 Hello i have 2 variables of type int that i would like to bind to the min and max values of an input of type time . How can i do this? I do not know what to place in the bind field since there are 2 different variables. Also there is the min and max attributes. <input type="time" min="@model.min" max="@model.max" bind=?/> What should i put in the bind ? Update On a more thoroughly analysis i decided i will need 2 variables of type Timespan and i will bind these to 2 inputs of type time . 回答1:

问题 One would think this is an easy task. But how do I call a service method on component load without it firing twice? Currently - protected override async Task OnInitializedAsync() { await Initialize(); } private async Task Initialize() { Video = await _VideoService.GetAsync(Id); } Right now this gets called twice, which doens't seem like a good idea to hit the database twice for the same information. I've tried just having this below, but it will throw an error before it even renders everytime

问题 I am using the server-side of Blazor. I want to change the CSS of the body. In Jquery I can write the code like this easily: $("body").css("overflow-y","hidden"); However, with this tutorial(Blazor Change Validation default css class names) said, it seems I can only change the CSS by changing the class name. It is so complex while crossing the component, especially the body is at the top of all the components. I wonder whether there is a way can changes CSS directly in Blazor. Thank you. 回答1:
