I am trying to pass my model to a controller using JQuery/Ajax, I'm not sure how to do this correctly. So far I have tried using Url.Action but the model is blank.
Note: none of the duplicate threads on stackoverflow seem to address using ASP.NET 5 MVC 6.
View:
$("#inpDateCompleted").change(function () {
var url = '@(Url.Action("IndexPartial", "DashBoard", Model, null))';
$("#DailyInvoiceItems").load(url);
});
Controller:
[HttpGet]
public PartialViewResult IndexPartial(DashBoardViewModel m)
{
// Do stuff with my model
return PartialView("_IndexPartial");
}

Looks like your IndexPartial action method has an argument which is a complex object. If you are passing a a lot of data (complex object), It might be a good idea to convert your action method to a HttpPost action method and use jQuery post to post data to that. GET has limitation on the query string value.
[HttpPost]
public PartialViewResult IndexPartial(DashboardViewModel m)
{
//May be you want to pass the posted model to the parial view?
return PartialView("_IndexPartial");
}
Your script should be
var url = "@Url.Action("IndexPartial","YourControllerName")";
var model = { Name :"Shyju", Location:"Detroit"};
$.post(url, model, function(res){
//res contains the markup returned by the partial view
//You probably want to set that to some Div.
$("#SomeDivToShowTheResult").html(res);
});
Assuming Name and Location are properties of your DashboardViewModel class and SomeDivToShowTheResult is the id of a div in your page where you want to load the content coming from the partialview.
You can build more complex object in js if you want. Model binding will work as long as your structure matches with the viewmodel class
var model = { Name :"Shyju",
Location:"Detroit",
Interests : ["Code","Coffee","Stackoverflow"]
};
$.ajax({
type: "POST",
data: JSON.stringify(model),
url: url,
contentType: "application/json"
}).done(function (res) {
$("#SomeDivToShowTheResult").html(res);
});
For the above js model to be transformed to your method parameter, Your View Model should be like this.
public class DashboardViewModel
{
public string Name {set;get;}
public string Location {set;get;}
public List<string> Interests {set;get;}
}
And in your action method, specify [FromBody]
[HttpPost]
public PartialViewResult IndexPartial([FromBody] DashboardViewModel m)
{
return PartialView("_IndexPartial",m);
}
