MVC视图-> JavaScript->控制器方法-> Javascript-> Div标签 [英] MVC View-> JavaScript->Controller method->Javascript->Div tag

问题描述

我有一个创建，编辑，删除应用程序.在我的索引视图中，有用于编辑的按钮.通过单击此按钮，它将打开弹出窗口，其中应显示所有数据以进行编辑.

I have a create,edit,delete application On my Index view i have Button for Edit. by clicking this button it should open pop up in which all data should be displayed for editing.

要实现此目的，我传递了正在编辑的那一行的ID.参见下面的代码:

To achieve this i passed ID of that row which is getting Edited. see code below :

  <td>
    <button type="button" onclick="EditPopup(@item.Id)">Edit</button>
    </td>

在这里，我正在将ID传递给我的EditPopup javascript方法.参见下面的方法:

here i am passing ID to my EditPopup javascript method. see the method below :

<script type="text/javascript">
$(document).ready(function () {
    $("#EditDialog").dialog({
        autoOpen: false,
        title: 'Title',
        width: 'auto',
        height: 'auto',
        modal: true
    });
});

function EditPopup(Get_Id) {
   alert(Get_Id) // I am getting correct ID here.
    $.ajax({

        method: "POST",
        url: '@Url.Action("Edit","Home")',
        dataType: 'json',
        cache: false,
        data:{Get_Id}, // tried : {id:Get_Id} , {id:"Get_Id"} not working
        success: function (data) {

            $('#EditDialog').html(data);
        }

    });
    $("#EditDialog").dialog("open");
}</script>

我正在将ID的值发送到我的Controller方法.这就是为什么我在ajax调用中使用Post方法的原因. Edit是方法的名称，Home是控制器的名称.

I am sending value of ID to my Controller method Edit thats why i am using Post method in ajax call. Edit is name of method and Home is name of controller.

HomeController编辑方法

 [HttpPost]
    public JsonResult Edit(int? id)
    {

        FloorFactor floorFactor = db.FloorFactors.Find(id);

        return Json(floorFactor, JsonRequestBehavior.AllowGet);
    }

    // POST: 
    [HttpPost]
    public ActionResult Edit(int id, FormCollection collection)
    {

        FloorFactor floorFactor = db.FloorFactors.Find(id);

        return View(floorFactor);
    }

在一些示例中，我看到在ajax调用中，它们通常使用json结果方法.所以这就是我也使用json结果方法的原因.

in few examples i saw that in ajax call they usually use json result method. so that is the reason i also used json result method.

最后在我的索引视图中显示弹出结果的代码.

finally Code which is in my index view where i will show pop up result.

<div id="EditDialog" style="display:none;">
<label> Floor Factor </label>
<br />
<label> Effective From :</label>

所以整个场景是:

我将按钮点击事件的ID值发送给javascript.
在javascript上，我调用了我的控制器方法以获取数据.
这些应该在div的EditDialog框中传递.
在div块上，它应该显示为弹出窗口.

I send id value on button click event to javascript.
on javascript i make a call to my controller method to get data.
those should pass in EditDialog box of div.
on div block it should display in pop up.

当前输出:

我还想了解ajax调用中url字段的工作方式.
如果我将多列结果作为该URL的输出，如何在ajax调用的Data部分中收集所有输出.
请同时说明成功后我可以在函数中传递哪些参数.

I also want to understand how url field works in ajax call.
if i am getting multiple column results as output of that url how can i collect all output in Data part of ajax call.
please also explain on success what parameters i can pass in function.

感谢您的解释和帮助.

控制台"选项卡上没有显示错误. 如该脚本标签中所示，我认为它正在发送请求，因为它生成了请求ID.

Edit : It shows no error on console tab. as shown in this script tab i think it is sending a request as it generates request Id.

推荐答案

尝试以下更改

操作代码:

[HttpPost]
    public JsonResult Edit(int? id)
    {

        FloorFactor floorFactor = db.FloorFactors.Find(id);

        return Json(floorFactor, JsonRequestBehavior.AllowGet);
    }

查看更改

<div id="EditDialog" style="display:none;">
<label> Floor Factor </label> <span id="floorFactor"></span>
<br />
<label> Effective From :</label> <span id="effectiveFrom"></span>

成功的方法更改

      if(data)
      {
//  GET VALUES
         var floorFactor = data.Property_Having_FloorFactor;
         var effectiveFrom = data.Property_Having_EffectiveFrom; 
// ASSIGN VALUES
         $('#floorFactor').text(floorFactor);
         $('#effectiveFrom ').text(effectiveFrom );
// OPEN DIALOG
         $("#EditDialog").dialog("open");
      }

希望它会为您工作.
