在 Visual Studio 2022 中的另一个局部视图（cshtml / cshtml.cs 文件）中访问 Web API 响应 object

Question

On click of a button will from a partialview 1 below js function will be called and get the data from the controller and will be redirected to another partialview. Since it the controller is in another project and hosted separately, controller is not returning the partialview hence I am redirecting it if the ajax call is success.

$.ajax({
    type: "POST",
    url: url,
    data: JSON.stringify(paramObj),
    contentType: "application/json; charset=utf-8",
    traditional: true,
    success: function (response) {
        var userObject = response.internalObject;
    window.location.href = url2;
    },
    error: function (response, status, error) {
        if (response.responseText != undefined) {
            const obj = JSON.parse(response.responseText);
            fnShowMessage(obj.DisplayMessage);
        }
    }

});

I have the data in "userObject" from the ajax call which needs to be displayed in partialview, but I cannot access it or not sure how to access it.

The assigned value in OnGet() method in "partialview2.cshtml.cs" is able to retain in "partialview2.cshtml" file. But how to get the values which I got from the ajax call in partialview 1 in code behind of partialview 2.

public class UserModel : PageModel
{
    [BindProperty]
    public UserObject UserObject { get; set; } = new();
    public void OnGet()
    {
        UserObject.UserName = "man";
    }
}

You can try to return JsonResult in OnGet:

ajax:

$.ajax({
                type: "POST",
                url: "/Home/Test",
                data: JSON.stringify(paramObj),
                contentType: "application/json; charset=utf-8",
                traditional: true,
                dataType: "json",
                success: function (response) {
                    var userObject = response;
                    window.location.href = url2;
                },
                error: function (response, status, error) {
                    if (response.responseText != undefined) {
                        const obj = JSON.parse(response.responseText);
                        fnShowMessage(obj.DisplayMessage);
                    }
                }
            });

OnGet handler:

public class UserModel : PageModel
{
    [BindProperty]
    public UserObject UserObject { get; set; } = new();
    public JsonResult OnGet()
    {
        UserObject.UserName = "man";
        return new JsonResult(UserObject);
    }
}
