In doing an auto-refresh using the following code, I assumed that when I do a post, the model will automatically sent to the controller:
$.ajax({
url: '<%=Url.Action("ModelPage")%>',
type: "POST",
//data: ??????
success: function(result) {
$("div#updatePane").html(result);
},
complete: function() {
$('form').onsubmit({ preventDefault: function() { } });
}
});
Every time there is a post, I need to increment the value attribute in the model:
public ActionResult Modelpage(MyModel model)
{
model.value = model.value + 1;
return PartialView("ModelPartialView", this.ViewData);
}
But the model is not passed to the controller when the page is posted with jQuery AJAX request. How can I send the model in the AJAX request?
The simple answer (in MVC 3 onwards, maybe even 2) is you don't have to do anything special.
As long as your JSON parameters match the model, MVC is smart enough to construct a new object from the parameters you give it. The parameters that aren't there are just defaulted.
For example, the Javascript:
var values =
{
"Name": "Chris",
"Color": "Green"
}
$.post("@Url.Action("Update")",values,function(data)
{
// do stuff;
});
The model:
public class UserModel
{
public string Name { get;set; }
public string Color { get;set; }
public IEnumerable<string> Contacts { get;set; }
}
The controller:
public ActionResult Update(UserModel model)
{
// do something with the model
return Json(new { success = true });
}
