ASP.Net Mvc 如何使用 Ajax 使用按钮将数据从视图传递到 Controller

Question

我有一个按钮，它从 Model 获取数据并将其传递给 Ajax function。 然后，这个 function 应该调用 controller，但它不会调用 controller 上的断点。

参数取自 Model 的按钮（均为字符串）：

<button class="btn btn-primary btn-lg active" onclick="PassHwData(@obj.Name,@obj.HomeWorldBonus)" >Choose @obj.Name</button>

Ajax function：

<script>
          function PassHwData(name, hwBonus)
          {
              $.ajax({
                  url: '@Url.Action("Create", "HomeWorld")',
                  type: "POST",
                  data: {'name' : name, 'hwBonus' : hwBonus}
                  datatype: "text",
                  success: function(name, hwBonus)
                  {
                      document.getElementById('success').innerHTML += success {name}{hwBonus};
                  }
              })
          }
</script>

<div id=success>
      success: 
</div>

Controller（还有其他方法，但我在这里省略了）：

using DarkHeresy.Application.Services.Interfaces;
using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Mvc;

namespace DarkHeresy.Web.Controllers
{
    [Authorize]
    public class HomeWorldController : Controller
    {
        private readonly IHomeWorldService _homeWorldService;
        public HomeWorldController(IHomeWorldService homeWorldService)
        {
            _homeWorldService = homeWorldService;
        }
        [HttpPost]
        public async Task<IActionResult> Create(string name, string hwBonus)
        {
            return View(await _homeWorldService.UpdateCharacterList()); //this will have implementation later
        }
    }
}

我还应该补充一点，我正在使用 Asp.Net Core MVC 并使用 Clean Architecture，并且在这两方面都非常新。

Answer 1

您可以使用这种替代方式通过AJAX将数据发送到您的Controller方法：

HTML：

<button class="btn btn-primary btn-lg active" onclick="PassHwData('@obj.Name','@obj.HomeWorldBonus')" >Choose @obj.Name</button>

AJAX：

<script>
          function PassHwData(name, hwBonus)
          {
              console.log(name);
              console.log(hwBonus);
              var json = {
                   name : name,
                   hwBonus : hwBonus
              };
              
              $.ajax({
                  type: "POST",
                  url: "@Url.Action("Create", "HomeWorld")",
                  dataType: "json",
                  data: {"json": JSON.stringify(json)},
                  success: function(name, hwBonus)
                  {
                      document.getElementById('success').innerHTML += success {name}{hwBonus};
                  }
              })
          }
</script>

<div id="success">
      success: 
</div>

Controller 方法：

using DarkHeresy.Application.Services.Interfaces;
using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Mvc;
using System.Text.Json; //For .NET CORE

namespace DarkHeresy.Web.Controllers
{
    [Authorize]
    public class HomeWorldController : Controller
    {
        private readonly IHomeWorldService _homeWorldService;
        public HomeWorldController(IHomeWorldService homeWorldService)
        {
            _homeWorldService = homeWorldService;
        }
        
        [HttpPost]
        public async Task<IActionResult> Create(string json)
        {
            var jsondata = JsonSerializer.Deserialize<dynamic>(json);
            //Get your variables here from AJAX call
            var name = jsondata["name"];
            var hwBonus = jsondata["hwBonus"];
            return View(await _homeWorldService.UpdateCharacterList()); //this will have implementation later
        }
    }
}

Answer 2

将 ajax 的数据类型更改为“json”
