asp.net-core-2.0 – 如何从Core 2 RazorPage ViewModel Handler

查看模型/处理程序

public async Task<IActionResult> OnGetAsyncUpdateSearchResults(DateTime startDate,DateTime endDate,string selectedTypes)
{
    int[] types = selectedTypes.Split(",").Select(x => int.Parse(x)).ToArray();

    var inventory = await _itemService.GetFiltered(types,null,startDate,endDate.ToUniversalTime(),null);

    if (inventory != null)
    {
        SearchResultsGridPartialModel = new SearchResultsGridPartialModel();
        SearchResultsGridPartialModel.TotalCount = inventory.TotalCount;
        SearchResultsGridPartialModel.TotalPages = inventory.TotalPages;
        SearchResultsGridPartialModel.PageNumber = inventory.PageNumber;
        SearchResultsGridPartialModel.Items = inventory.Items;
    }

    var myViewData = new ViewDataDictionary(new Microsoft.AspNetCore.Mvc.ModelBinding.EmptyModelMetadataProvider(),new Microsoft.AspNetCore.Mvc.ModelBinding.ModelStateDictionary()) { { "SearchResultsGridPartialModel",SearchResultsGridPartialModel } };
    myViewData.Model = SearchResultsGridPartialModel;

    PartialViewResult result = new PartialViewResult()
    {
        ViewName = "SearchResultsGridPartial",ViewData = myViewData,};

    return result;
}

我现在可以通过ajax GET调用这个处理程序并让它返回部分的HTML.然后我可以按预期设置部分的div和部分刷新.

这是我正在制作的AJAX调用：

var jsonData = { "startDate": startDate,"endDate": endDate,"selectedTypes": selectedTypesAsString };

$.ajax({
    type: 'GET',url: "searchresults/?handler=AsyncUpdateSearchResults",beforeSend: function (xhr) {
        xhr.setRequestHeader("XSRF-TOKEN",$('input:hidden[name="__RequestVerificationToken"]').val());
    },contentType: 'application/json; charset=utf-8"',data: jsonData,success: function (result) {
        $("#searchResultsGrid").html(result);
    },error: function (error) {
        console.log(error);
    }
});
