[英]Posting back a dynamic list model to controller using AJAX and javascript
I have a partial view that displays in a jquery modal popup window. 我有一个局部视图,显示在jquery模态弹出窗口中。 The view is made up of a dynamically generated list of checkboxes and can contain one to many checkboxes.
该视图由动态生成的复选框列表组成,并且可以包含一对多的复选框。 I am having a problem with trying to post the model back to the controller.
我在尝试将模型发布回控制器时遇到问题。 The model is a generic list(of T)
该模型是T的通用列表
Below is the controller action: 以下是控制器操作:
<HttpPost>
Function CertBodiesListPostBack(ByVal Model As List(Of DataModels.DataModels.CertBodyVM)) As JsonResult
ViewBag.CourseId = Model(0).courseId
Data_Manager.CertifyBody.SaveCertBody(Model(0).courseId, Model)
Return Json(New With {.success = True})
End Function
and the view view is like this: 并且视图视图是这样的:
@Modeltype List(Of DataModels.CertBodyVM)
@Code
End Code
<link href="@Url.Content("~/Content/jquery-ui-1.10.3.custom.css")" rel="stylesheet" type="text/css" />
<script type="text/javascript">
$(document).ready(function () {
$("#btnUpdate").click(function () {
$('#waitMessage').show();
$.ajax({
url: '@Url.Action("CertBodiesListPostBack", "Admin")',
type: 'POST',
data: JSON.stringify('@model'),
dataType: "json",
context: $(this),
success: function (result) {
$('#waitMessage').hide();
$("#dialog-edit").dialog().dialog('close');
},
error: function (result) {
alert('There was an error processing the request!!');
}
});
return false;
});
});
</script>
<style>
#waitMessage {
background: url('../../Content/Images/animated-processing.gif') scroll no-repeat center;
height: 100px; width: 100px;
position: fixed; left: 50%; top: 50%; z-index: 1000;
margin: -25px 0 0 -25px;
}
</style>
<div id="waitMessage" class="dataContainer" style="display: none;">
<p>Saving Note</p>
</div>
@Using Html.BeginForm()
@<fieldset><legend></legend>
<table>
<tr>
<th>Certifying Bodies</th>
</tr>
@For i As Integer = 0 To Model.Count - 1
Dim y As Integer = i
Dim d As String = Model(y).certName
@<tr><td style="text-align: left">@Html.CheckBoxFor(Function(model) model(y).certSelected)@Html.Label(d)@Html.HiddenFor(Function(model) model(y).certBodyId)@Html.HiddenFor(Function(model) model(y).courseId)</td></tr>
Next
</table>
<input type="button" value="Save" id="btnUpdate" name="cmd" class="ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only" />
<input type="button" value="Cancel" id="btncancel" class="ui-button ui-widget ui-state-default ui-corner-all ui-button-text-only" />
</fieldset>
End Using
And the model is as Follows: 该模型如下:
Public Class CertBodyVM
Private _certName As String
Public Property certName() As String
Get
Return _certName
End Get
Set(ByVal value As String)
_certName = value
End Set
End Property
Private _certSelected As Boolean
Public Property certSelected() As Boolean
Get
Return _certSelected
End Get
Set(ByVal value As Boolean)
_certSelected = value
End Set
End Property
Private m_certBodyId As Integer
Public Property certBodyId() As Integer
Get
Return m_certBodyId
End Get
Set(ByVal value As Integer)
m_certBodyId = value
End Set
End Property
Private m_CourseId As Integer
Public Property courseId() As Integer
Get
Return m_CourseId
End Get
Set(ByVal value As Integer)
m_CourseId = value
End Set
End Property
End Class
I am new to javascript and AJAX so 我是javascript和AJAX的新手,所以
If you want to pass the model on view to the controller using ajax call you can use 如果您想使用ajax调用将视图上的模型传递给控制器,则可以使用
data: $('form').serialize()
You can specify id to form and pass id of the form as 您可以指定表单的ID,并以以下形式传递表单的ID:
data: $('#myform').serialize()
