[英]C# Razor Page Dynamically Create Divs with Attributes
我有以下CSHTML代碼:
<div class="container-fluid projects padding-top-small">
<div class="row">
<div class="col-sm-6 col-md-3">
<div class="project-inner">
<a href="service1.html">
<img src="assets/img/portfolio/image1.jpg" alt="">
<div class="project-caption">
<div class="project-details">
<p><i class="fa fa-plus fa-lg"></i></p>
<h3>Service 1</h3>
<p><small>Short Description 1</small></p>
</div>
</div>
</a>
</div>
</div>
<div class="col-sm-6 col-md-3">
<div class="project-inner">
<a href="service2.html">
<img src="assets/img/portfolio/image2.jpg" alt="">
<div class="project-caption">
<div class="project-details">
<p><i class="fa fa-plus fa-lg"></i></p>
<h3>Service 2</h3>
<p><small>Short Description 2</small></p>
</div>
</div>
</a>
</div>
</div>
<div class="col-sm-6 col-md-3">
<div class="project-inner">
<a href="service1.html">
<img src="assets/img/portfolio/image3.jpg" alt="">
<div class="project-caption">
<div class="project-details">
<p><i class="fa fa-plus fa-lg"></i></p>
<h3>Service 3</h3>
<p><small>Short Description 3</small></p>
</div>
</div>
</a>
</div>
</div>
<div class="col-sm-6 col-md-3">
<div class="project-inner">
<a href="service1.html">
<img src="assets/img/portfolio/image4.jpg" alt="">
<div class="project-caption">
<div class="project-details">
<p><i class="fa fa-plus fa-lg"></i></p>
<h3>Service 4</h3>
<p><small>Short Description 4</small></p>
</div>
</div>
</a>
</div>
</div>
</div>
</div>
幾乎所有內容都是硬編碼的HTML標簽。
我希望能夠動態渲染它們。
在我的控制器中,我正在檢索一個由以下各項組成的服務對象列表:SERVICE_URL,SERVICE_IMAGE_URL,SERVICE_NAME和SERVICE_DESCRIPTION。 這些列表存儲在ViewBag中(不確定Viewbag是否是最好的占位符)。
<div class="col-sm-6 col-md-3">
<div class="project-inner">
<a href="SERVICE_URL">
<img src="SERVICE_IMAGE_URL" alt="">
<div class="project-caption">
<div class="project-details">
<p><i class="fa fa-plus fa-lg"></i></p>
<h3>SERVICE_NAME</h3>
<p><small>SERVICE_DESCRIPTION</small></p>
</div>
</div>
</a>
</div>
</div>
我想要實現的是使每個div動態呈現,這樣我將只能顯示那些可用的服務。
Controller.cs
public class myService
{
public string service_url { get; set; }
public string service_image_url { get; set; }
public string service_name { get; set; }
public string service_description { get; set; }
}
private void loadServices()
{
List<myService> myServices = new List<myService>();
for(int i=0; i<3; i++)
{
myService msvc = new myService();
msvc.service_url = "service_url" + i.ToString() + ".html";
msvc.service_image_url = "image_url" + i.ToString() + ".jpg";
msvc.service_name = "Service " + i.ToString();
msvc.service_description = "Service Description " + i.ToString();
myServices.Add(msvc);
}
ViewBag.DataServices = myServices;
}
public ActionResult Home()
{
loadServices();
return this.RedirectToAction("Index", "Controller");
}
改寫問題:在我的控制器上,我有一個服務列表並將其存儲到ViewBag中,如何在Razor頁面上生成具有從硬編碼HTML提供的屬性的DIV?
我為此構建了一個工作原型,並將逐步指導您完成每個部分的步驟。 然后,我建議您找到一些有關MVC Razor編程的不錯的基礎書籍,並從頭開始,因為有很多細節需要學習:
例如Models \\ MyService.cs:
namespace WebApplication.Models
{
public class MyService
{
public string ServiceUrl { get; set; }
public string ServiceImageUrl { get; set; }
public string ServiceName { get; set; }
public string ServiceDescription { get; set; }
}
}
Home
控制器需要“ Services
操作,因此URL路由來自有意義的/Home/Services
Controllers \\ HomeController.cs:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc;
using WebApplication5.Models;
namespace WebApplication.Controllers
{
public class HomeController : Controller
{
private List<MyService> LoadServices()
{
List<MyService> myServices = new List<MyService>();
for (int i = 0; i < 3; i++)
{
MyService msvc = new MyService();
msvc.ServiceUrl = "service_url" + i.ToString() + ".html";
msvc.ServiceImageUrl = "image_url" + i.ToString() + ".jpg";
msvc.ServiceName = "Service " + i.ToString();
msvc.ServiceDescription = "Service Description " + i.ToString();
myServices.Add(msvc);
}
return myServices;
}
public ActionResult Services()
{
// return a view using the ViewModel provided by LoadServices()
return View(LoadServices());
}
}
}
Views \\ Home \\ Services.cshtml:
@model IEnumerable<WebApplication.Models.MyService>
<div class="container-fluid projects padding-top-small">
<div class="row">
@foreach (var service in Model)
{
<div class="col-sm-6 col-md-3">
<div class="project-inner">
<a href="@service.ServiceUrl">
<img src="@service.ServiceImageUrl" alt="">
<div class="project-caption">
<div class="project-details">
<p><i class="fa fa-plus fa-lg"></i></p>
<h3>@service.ServiceName</h3>
<p><small>@service.ServiceDescription</small></p>
</div>
</div>
</a>
</div>
</div>
}
</div>
</div>
所有這些工作的最終結果如下所示:
