javascript - 如何将数据从表单传递到我的 Controller ，然后返回到我的客户端 javascript？

Question

我的网页中有一个表格，要求输入名字和姓氏。当用户提交此表单时，我希望将数据传递到我的 Controller 中的一个函数，用于在我们的 Active Directory 中查找相应的用户。然后我想将匹配的电子邮件地址返回给 Javascript 函数，然后在我的页面上显示该信息。这是执行此操作的“正确”方法吗？如果是，我将如何在我的 Controller 中构造一个函数来接受表单输入，并将数据返回到我的客户端 javascript？

到目前为止我的 Controller 中有什么:

 public SearchResult[] searchAD(String fname, String lname)
    {
        Func<System.DirectoryServices.ActiveDirectory.Domain> domain = System.DirectoryServices.ActiveDirectory.Domain.GetCurrentDomain;
        System.DirectoryServices.DirectoryEntry root = new DirectoryEntry("LDAP://"+domain);
        DirectorySearcher searcher = new DirectorySearcher();
        searcher.SearchRoot = root;
        searcher.SearchScope = SearchScope.Subtree;
        searcher.Filter = string.Format("(&(objectCategory=person)(objectClass=user)(givenName={0})(sn={1}))", fname, lname);
        SearchResult[] results = new SearchResult['a'];
        searcher.FindAll().CopyTo(results, 0);
        return results;
    }

还有我的表格:

@using (Html.BeginForm("searchAD", "AD", FormMethod.Post))
    {
        @Html.AntiForgeryToken()

        @Html.ValidationSummary(true, "", new { @class = "text-danger" })
        <div class="form-group">
            @Html.LabelFor(m => m.firstName, "First Name", htmlAttributes: new { @class = "control-label" })
            <div>
                @Html.EditorFor(model => model.firstName, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.firstName, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">
            @Html.LabelFor(m => m.lastName, "Last Name", htmlAttributes: new { @class = "control-label" })
            <div>
                @Html.EditorFor(model => model.lastName, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.lastName, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">
            <div>
                <input type="submit" value="Search" class="btn" />
            </div>
        </div>
    }

您可以将值存储在 TempData 中并在 View 中获取它

 public ActionResult searchAD(String fname, String lname)
    {
        Func<System.DirectoryServices.ActiveDirectory.Domain> domain = System.DirectoryServices.ActiveDirectory.Domain.GetCurrentDomain;
        System.DirectoryServices.DirectoryEntry root = new DirectoryEntry("LDAP://"+domain);
        DirectorySearcher searcher = new DirectorySearcher();
        searcher.SearchRoot = root;
        searcher.SearchScope = SearchScope.Subtree;
        searcher.Filter = string.Format("(&(objectCategory=person)(objectClass=user)(givenName={0})(sn={1}))", fname, lname);
        SearchResult[] results = new SearchResult['a'];
        searcher.FindAll().CopyTo(results, 0);
        TempData["Result"]=results;
        return View("ViewName");
    }

在 View 中(Jquery)

$(function(){
     if ('@TempData["Result"]' != '')
      {
         // call your function here and pass TempData Value
      } 
});
