MVC视图-> JavaScript->控制器方法-> Javascript-> Div标签

Question

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.

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>

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>

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 Edit methods

 [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);
    }

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.

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>

So the Whole scenario is :

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.

Current output :

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.

Thank you for explanation and help.

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.

Answer 1

Try the below changes

Action Code :

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

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

        return Json(floorFactor, JsonRequestBehavior.AllowGet);
    }

View Changes

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

Success method changes

      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");
      }

Hope it will work for you.

Answer 2

Change the Controller as

[HttpGet]
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);
}

Change the 'ajax' as

$.ajax({
    method: "GET",
    url: '@Url.Action("Edit","Home")',
    dataType: 'json',
    cache: false,
    data: {id:Get_Id},
    success: function (data) {
        $('#EditDialog').html(data);
    }
});

Note: Code is untested. It should have work for you.
