Question: how to get values all inputs? in razor page and input model class?

Since you use $formGroup.clone() , you could simply apply same name attribute on all inputs and save it as List<string> in PageModel. For example：

1.page.cshtml

@model TestInputModel
<form method="post">
<div class="form-group input-group">
    <input type="text" class="form-control" name="MyAllInputs">
    <span class="input-group-btn">
        <button type="button" class="btn btn-default btn-add">
            +
        </button>
    </span>
</div>
<div class="form-group">
    <input type="submit" value="Submit" class="btn btn-primary" />
</div>
</form>
@section Scripts{
 <script>...</script>
}

2.PageModel

public class TestInputModel : PageModel
{
    //using your db context by DI
    private readonly MyApplicationDbContext _context;

    public TestInputModel(MyApplicationDbContext context)
    {
        _context = context;
    }

    //bind your all inputs' values
    [BindProperty]
    public List<string> MyAllInputs{ get; set; }

    public void OnGet()
    {

    }

    public void OnPost()
    {
        //logic to save you input values to dbcontext
        var data = MyAllInputs;
        //...
    }
}
