Question

我仍在学习MVC。我在使用部分视图时遇到问题。我有一个带有下拉菜单值的页面。并且，每当用户选择该值时，就会出现带有数据表的部分页面。

当前，我正在考虑使用JQuery加载功能将页面加载到div标签中。但是数据表未显示。我的代码有问题吗？或者有更好的方法吗？请帮忙。谢谢。

我的观点：

    @model MVCWeb.Models.DP_Table
@{
    ViewBag.Title = "Data Patching";
}

<br />

<h2>@ViewBag.Title</h2>

<br />

<table class="table-striped table-responsive">
    <tbody>
        <tr>
            <td width="40%">
                <label class="control-label">Select Table</label>
            </td>
            <td width="10%">:</td>
            <td width="*%">
                @Html.DropDownListFor(Model => Model.DPTableID, new SelectList(Model.TableCollection,
                "DPTableId", "TableName"), "Please Select", new { @id = "ddTableName", @class = "form-control" })
            </td>
        </tr>
        <tr>
            <td><br /></td>
        </tr>
        <tr>
            <td>
                <label class="control-label">Select Action</label>
            </td>
            <td>:</td>
            <td>
                @Html.DropDownList("Actions", @ViewBag.PatchingActions as List<SelectListItem>,
                "Please Select", new { @id = "ddPatchingAction", @class = "form-control", @disabled = "disabled" })
            </td>
        </tr>
    </tbody>
</table>

<br />

<div id="divPatching"></div>

@section scripts{
    <script src="//cdn.datatables.net/1.10.19/js/jquery.dataTables.min.js"></script>

    <script>
        var ddTableValue, ddPatchingActionValue;

        $('#ddTableName').change(function () {
            ddTableValue = $('#ddTableName option:selected').val();
            if (ddTableValue) {
                $("#ddPatchingAction").prop("disabled", false);
            } else {
                $("#ddPatchingAction").prop("disabled", true);
            }
        });

        $('#ddPatchingAction').change(function () {
            ddPatchingActionValue = $('#ddPatchingAction option:selected').val();
            if (ddPatchingActionValue) {
                $("#divPatching").load('@Url.Action("GetPartialView", "DataPatching")');
            }
        });
    </script>
}

我的控制器：

public PartialViewResult GetPartialView()
    {
        return PartialView("~/Views/PatchingBatch/Index.cshtml");
    }

我的局部视图：

<a class="btn btn-success" style="margin-bottom:10px" onclick="AddUserForm('@Url.Action("AddUser", "Account")')"><i class="fa fa-plus"></i> Add New User</a>
<table id="batchTable" class="table-striped table-responsive">
    <thead>
        <tr>
            <th>Username</th>
            <th>Name</th>
            <th>Email Address</th>
            <th>Is Admin</th>
            <th></th>
        </tr>
    </thead>
</table>

我的部分控制器：

public ActionResult Index()
{
    return PartialView();
}

[HttpPost]
public ActionResult GetDPUserList()
{
    //server side parameter
    int start = Convert.ToInt32(Request["start"]);
    int length = Convert.ToInt32(Request["length"]);
    string searchValue = Request["search[value]"];
    string sortColumnName = Request["columns[" + Request["order[0][column]"] + "][name]"];
    string sortDirection = Request["order[0][dir]"];

    List<DP_User> userList = new List<DP_User>();
    using (DBModel db = new DBModel())
    {
        userList = db.DP_User.ToList<DP_User>();
        userList = userList.ToList<DP_User>();
        int totalrows = userList.Count();

        //search
        if (!string.IsNullOrEmpty(searchValue))
        {
            userList = userList.Where(x => (x.Username != null && x.Username.ToString().ToLower().Contains(searchValue)) ||
            (x.Name != null && x.Name.ToString().ToLower().Contains(searchValue)) ||
            (x.Email != null && x.Email.ToString().ToLower().Contains(searchValue))).ToList<DP_User>();
        }

        int totalrowsafterfilter = userList.Count();

        //sorting
        if (!string.IsNullOrEmpty(sortColumnName) && !string.IsNullOrEmpty(sortDirection))
        {
            userList = userList.OrderBy(sortColumnName + " " + sortDirection).ToList<DP_User>();
        }

        //paging
        userList = userList.Skip(start).Take(length).ToList<DP_User>();

        return Json(new { data = userList, draw = Request["draw"], recordsTotal = totalrows, recordsFiltered = totalrowsafterfilter },
            JsonRequestBehavior.AllowGet);
    }
}

Answer 1

1-创建一个Partial View到Page的名字

2-创建一个Action

public ActionResult YourPage()
    {
        return PartialView("~/Views/Page.cshtml");
    }

3-对您的视图创建一个div

<div id="MyDiv"></div>

4-将此代码写入script

$(document).ready(function () {
        $.get("/Home/YourPage", function (data) {
            $('#MyDiv').html(data);
        });
    });

Answer 2

如果您使用的是ASP.NET Core，则可以使用此命令

<partial name="_yourPartial" />

它将通过控制器中的方法为您加载视图

如果您使用的是ASP.NET的旧版本，则可以使用此旧命令

@Html.Partial("_yourPartial")

它的工作方式相同，避免使用jquery

您还可以使用命令在模型中传递模型

@Html.Partial("_yourPartial", new { paramName = "foo" })

如何在<DIV>标签中加载部分视图？
