tag-helpers

问题 According to this article if we use several tag helpers(targeted to the same tag) and in each of them we will use await output.GetChildContentAsync() to recieve html content we will come to the problem with cached output: The problem is that the tag helper output is cached, and when the WWW tag helper is run, it overwrites the cached output from the HTTP tag helper. The problem is fixed by using statement like: var childContent = output.Content.IsModified ? output.Content.GetContent() :

问题 I have read following posts from Damian Edwards. https://github.com/aspnet/Mvc/issues/1576 https://github.com/aspnet/Mvc/issues/1580 At the ScriptTagHelper , I'm not sure what I should enter on asp-fallback-test attribute ? It's the same as for jQuery ? window.jQuery ? How do I find the correct JavaScript Expression? Can someone give me an example based on moment-withlocales.min.js ? Thanks!

问题 I've been reading about the new support for Tag Helpers in MVC 6 and now need to create my own. I see that the built in tag helpers for existing HTML elements are all prefixed with "asp-" For example: <a asp-controller="Home" asp-action="Index">Home</a> But what about my own custom tag helpers. Should I also prefix those with "asp-" to show that it is running on the server. Or should this be reserved for framework attributes? Should I create my own project/company named prefix instead? Is

问题 Is it possible in ASP.Net Core to automatically convert camel case property names in view models to insert spaces into the corresponding labels when using tag helpers? If my view model looks like this... [Display(Name = "First Name")] public string FirstName { get; set; } [Display(Name = "Last Name")] public string LastName { get; set; } [Display(Name = "Referral Date")] public DateTime ReferralDate { get; set; } It seems like a lot of extra configuration applying data annotations such as

问题 When specifying asp-controller and asp-action on a link, what's the syntax for also passing an id attribute? E.g. If I wanted to link to the edit URL for a given object, the required URL would be /user/edit/5 for example. Is there a method to achieve this using TagHelpers, or do we still have to fall back to @Html.ActionLink() ? 回答1: You can use the attribute prefix asp-route- to prefix your route variable names. Example: <a asp-action="Edit" asp-route-id="10" asp-route-foo="bar">Edit</a> 回答2

问题 I want to add the integrity attribute to a script tag in my tag helper. It contains a + sign which I don't want encoded. <script integrity="sha384-Li9vy3DqF8tnTXuiaAJuML3ky+er10rcgNR/VqsVpcw+ThHmYcwiB1pbOxEbzJr7"></script> This is my tag helper: [HtmlTargetElement(Attributes = "script")] public class MyTagHelper : TagHelper { public override async Task ProcessAsync(TagHelperContext context, TagHelperOutput output) { // Omitted... output.Attributes["integrity"] = "sha384

问题 I am having trouble getting Tag Helpers enabled in my project. Here is a summary of the project setup: VS 2015 RC Community Edition. Project.json reference: Microsoft.AspNet.Mvc": "6.0.0-beta4 _GlobalImport.chtml has @addTagHelper"*,Microsoft.AspNet.Mvc.TagHelpers" No build errors or warnings.

问题 I am having issues with .NET core and tag helpers. The color coding and the intellisense are not displaying or being registered when I type in asp-for. I've tried creating a new solution in a separate instance, verified that the intellisense works, and then copied the project.json into the project that doesn't have working intellisense/color coding, and it doesn't fix the issue. Here is my project.json { "dependencies": { "Microsoft.NETCore.App": { "version": "1.0.0", "type": "platform" },
