Question

我创建了PowerShell脚本，以便在网页加载组名称时将其加载到下拉列表中，以获取活动目录组。我要尝试做的下一件事是使用搜索按钮click事件，通过传递PowerShell脚本将组详细信息加载到文本区域中，并将成员加载到表中。我正在使用库System.Management.Automation处理PowerShell脚本。当我直接使用PowerShell时，我不希望我的项目依赖于任何模型类。因此，我仅在控制器和视图之间进行交互。

控制器代码：

using System.Web.Mvc;
using System.Collections.Generic;
using System.Text;
using System.Management.Automation;
using System.Linq;
using System;

namespace MyProject.UI.MVC5.Controllers
{
    public class GroupController : Controller
    {
        //
        // GET: /Group/
        public ActionResult Index()
        {
            return View();
        }

        public ActionResult GroupReview()
        {
            ViewBag.Message = "Group Review";
            ViewBag.Domains = PowerShellExecutorLst(AppDomain.CurrentDomain.BaseDirectory + "Shell\\Get-ADDomain.ps1");
            ViewBag.Groups = PowerShellExecutorLst(AppDomain.CurrentDomain.BaseDirectory + "Shell\\Get-ADStewardGroups.ps1");
            return View();
        }

        [HttpPost]
        public ActionResult FillDetails(string GroupName)
        {
            ViewBag.SDC = PowerShellExecutorStr(AppDomain.CurrentDomain.BaseDirectory + "Shell\\Get-SDC.ps1 '"+ GroupName +"'");
            return View();
        }

        // Fetching DropDownItems from Powershell Script Output
        public List<SelectListItem> PowerShellExecutorLst(string scriptPath)
        {
            string outString = "";
            var shell = PowerShell.Create();
            shell.Commands.AddCommand(scriptPath);
            var results = shell.Invoke();
            if (results.Count > 0)
            {
                var builder = new StringBuilder();
                foreach (var psObj in results)
                {
                    builder.Append(psObj.BaseObject.ToString() + "\r\n");
                }
                outString = Server.HtmlEncode(builder.ToString());
            }
            List<string> result = outString.Split(new char[] { '\n' }).ToList();
            List<SelectListItem> listItems = result.Select(s => new SelectListItem { Value = s, Text=s }).ToList();
            shell.Dispose();
            return listItems;
        }
        //Fetching String Values from Powershell Script Output
        private string PowerShellExecutorStr(string script)
        {
            string outString = "";
            var shell = PowerShell.Create();
            shell.Commands.AddCommand(script);
            var results = shell.Invoke();
            if (results.Count > 0)
            {
                var builder = new StringBuilder();
                foreach (var psObj in results)
                {
                    builder.Append(psObj.BaseObject.ToString() + "\r\n");
                }
                outString = Server.HtmlEncode(builder.ToString());
            }
            shell.Dispose();
            return outString;
        }
    }
}

在脚本中，我仅使用正常命令，例如get-ADUser和get-ADGroup，我需要将下拉文本作为参数传递给FillDetails（）控制器函数，但是当如何在文本区域中加载详细信息时点击事件发生了吗？

我正在调用PowerShellExecutorStr函数以在FillDetails（）函数中获取值，我只想尽可能使用Viewbag将这些值加载到专用区域中。

调用此脚本的Button中的onClick事件

@section scripts{
<script>
        function GetGroupDetails()
        {
            $.ajax({
                type: "POST",
                url: "/Group/FillDetails",
                data: { GroupName: $("#ddlGroup option:selected").text().trim()} ,
                success: function (response) {        
                        $("#txtSDC").val(response.message);                   
                }
             });

        }

</script>
}

但是，控制器方法需要返回Json结果

public JsonResult FillDetails(string GroupName)
        {
            var SDC = PowerShellExecutorStr(AppDomain.CurrentDomain.BaseDirectory + "Shell\\Get-SDC.ps1 '" + GroupName + "'");
            return Json(new { message = SDC }, JsonRequestBehavior.AllowGet);
        }

如何在MVC视图中单击按钮时使用控制器方法填充文本区域？
