如何通过AJAX在MVC3调用的局部视图 [英] How to call a partial view through ajax in MVC3

问题描述

我开发MVC3中的应用 我需要表现出点击下拉的partail视图 对于我写了一个AJAX，

I am developing an application in MVC3 I need to show a partail view on click of a dropdown For that i wrote an ajax,

 $("#UserName").change(function () {
        var userid = $("#UserName").val();
        var ProvincialStateID = $("#State").val();
        var Hobbyid = $("#Hobby").val();
        var Districtid = $("#DistrictNames").val();
        var Homeid = $("#Hobbyhome_EstablishmentId").val();
        var urlperson = '@Url.Action("FetchPersonByUserName")';
        $.ajax({
            type: "POST",
            url: urlperson,
            data: { userid: userid, stateid: ProvincialStateID, hobbyid: Hobbyid, districtid: Districtid, homeid: Homeid },
            success: function (data) {
            }
        });
    });

和我在控制器写了一个函数为：

and i wrote a function in controller as:

 [HttpPost]
    public ActionResult FetchPersonByUserName(int userid,int stateid,int districtid,int homeid,int Hobbyid)
    {
        //Code to fetch data using all the parameters
        return PartialView("_LearnerAssociationGridPartial", list);
    }

从这里进去的局部视图在那里，我也可以看到数据
但是，尽管它有前端我不能够看到的数据。
请帮我，也许我的ajax可能是错了，请告诉我在哪里，我要去错了。

From here it goes in the partial view there i can also see the data
But while it comes in the frontend i am not able to see the data.
Please Help me maybe my ajax may be wrong please tell me where i am goin wrong.

这是我的主要观点：

@model HobbyHomesWebApp.ViewModel.LearnerAssociationViewModel
@{
    Layout = "~/Views/Shared/_LayoutPostLogin.cshtml";
}

@using (Html.BeginForm("LearnerAssociation", "Registration", FormMethod.Post))
{
     @Html.ValidationSummary(true)
     <table>
         <div>
             @{Html.RenderPartial("_LearnerAssociationWebPartial", Model.learner);}
         </div> 
     </table>
     <table>
         <div id="result">
             @{Html.RenderPartial("_LearnerAssociationGridPartial", Model.LearnerList);}
         </div>
     </table>
}

AJAX的功能是写在第一视图和下拉列表中的第一个视图。
现在的onclick下拉在第一视图的我想的要显示的数据，其中在所述第二视图中的网格。

The ajax function is written in the first view and the dropdown is in the first view.
Now onclick of dropdown in first view i want the data to be displayed in a grid which is in the second view.

我的第一个观点是：

@using (Html.BeginForm("LearnerAssociation", "Registration", FormMethod.Post))
{
  <table>
    <tr>
        <td>
            @Html.Label(@Resources.selectusername)
        </td>
        <td>:</td>
        <td>
        <div class="editor-field">
            @Html.DropDownListFor(model => model.Loginaccount.LoginAccountID, new SelectList(ViewBag.UserName, "LoginAccount.LoginAccountID", "FirstName"), "--Select UserName--", new { @id = "UserName" })
        </div>
        </td>
    </tr>
            </table>

}

推荐答案

编辑：好，所以如果我理解正确的话，您认为应该是这样的：

OK so if I understand correctly, your view should look like this:

@model HobbyHomesWebApp.ViewModel.LearnerAssociationViewModel
@{
    Layout = "~/Views/Shared/_LayoutPostLogin.cshtml";
}

@using (Html.BeginForm("LearnerAssociation", "Registration", FormMethod.Post))
{
     @Html.ValidationSummary(true)
     <table>
         <tr>
         <td>
            <div>
                 @{Html.RenderPartial("_LearnerAssociationWebPartial", Model.learner);}
            </div> 
         </td>
         </tr>
     </table>
     <table>
         <tr>
         <td> 
             <div id="result">

            </div>
         </td>
         </tr>
     </table>
}

这意味着，当你第一次加载页面，没有显示在第二个 DIV 。

This means when you first load the page, nothing is displayed in the second div.

您再要加载的局部视图中的 DIV 根据选择的值。首先，添加JavaScript调用你已经描述的动作。

You then want to load a partial view in to the div based on the value selected. Firstly, add the javascript to call the action you have already described.

$('#NameOfYourDropDownList').change(function () {
    var userid = $('#NameOfYourDropDownList').val();
    var ProvincialStateID = $("#State").val();
    var Hobbyid = $('#Hobby').val();
    var Districtid = $('#DistrictNames').val();
    var Homeid = $('#Hobbyhome_EstablishmentId').val();
    var urlperson = "@Url.Action('FetchPersonByUserName')";
    $.ajax({
        type: 'POST',
        url: urlperson,
        data: { userid: userid, stateid: ProvincialStateID, hobbyid: Hobbyid, districtid: Districtid, homeid: Homeid },
        success: function (data) {
            $('#result').html(data);
        }
    });
});

在的ActionResult 将返回HTML。在你的成功的功能，你指定这是的HTML的 DIV 。

The ActionResult will return the HTML. In your success function, you are assigning this to be the HTML of the div.
