是否有使用 POST 而不是 GET 的 MVC 寻呼机？

Question

这是我的问题。我有一个 SearchViewModel 有大量搜索条件，这些值根本不适合 URL。我目前正在使用Troy Goode's Html.PagedListPager，但它被设计为使用Url.Action() 来发送URL 中的参数。这是一个例子。我不认为客户端过滤是一个选项，因为我会有很多记录。

 @Html.PagedListPager(
        (IPagedList)@Model.SearchResults,
        page => Url.Action("Results", 
            new {
                YearBuiltFrom = Model.YearBuiltFrom,
            }
                ))
}

如果您只有一两个简单参数，这是一个很好的解决方案。

搜索视图模型

  public class SearchViewModel
    {

        public int? page { get; set; }
        public int? size { get; set; }

        [IgnoreDataMember]
        public IPagedList<Property> SearchResults { get; set; }

        public string[] Locations { get; set; }

        [IgnoreDataMember]
        public MultiSelectList LocationOptions { get; set; }
        
        
        public string[] ZipCodes { get; set; }

        [IgnoreDataMember]
        public MultiSelectList ZipCodeOptions { get; set; }


        [Display(Name="Year Built")]
        public int? YearBuiltFrom  { get; set; }
     
        [Display(Name = "Year Built")]
        public int? YearBuiltTo { get; set; }
        public int? SqftFrom { get; set; }
        public int? SqftTo { get; set; }
        public string Bedrooms { get; set; }
        public string Bathrooms { get; set; }
        [DataType(DataType.Date)]
        public DateTime? SalesFrom { get; set; }
        [DataType(DataType.Date)]
        public DateTime? SalesTo { get; set; }
        public int? SaleAmountFrom { get; set; }
        public int? SaleAmountTo { get; set; }
        public int? LandAreaFrom { get; set; }
        public int? LandAreaTo { get; set; }
        
        public string[] Waterfront { get; set; }

        [IgnoreDataMember]
        public MultiSelectList WaterfrontOptions { get; set; }

     
        
        //TODO: Implement LandAreaType as a search parameter
        //public string LandAreaType { get; set; }
        public Boolean? IsVacant { get; set; }
        
        public string[] PropertyFeatures { get; set; }

        [IgnoreDataMember]
        public MultiSelectList PropertyFeatureOptions { get; set; }

    }

我不熟悉这样的控件。我认为最简单的方法是使用 javascript 来劫持对寻呼机锚点的点击，并通过取消将由锚点引起的默认重定向来动态构建 POST 请求。要构建此 POST 请求，您可以将当前页面值动态设置到搜索表单的隐藏字段中并触发此表单的提交，以便它再次执行搜索，但页面参数已更改。

举个例子：

<!-- Search form containing all the search criteria fields including the current page number
@using (Html.BeginForm(null, null, FormMethod.Post, new { id = "searchForm" }))
{
    @Html.EditorFor(x => x.SearchCriteria)
    <button type="submit">Search</button>
}

<!-- Here will be displayed the results
<div id="results">
    @Html.DisplayFor(x => x.SearchResults)
</div>

现在我们可以订阅寻呼机上的点击事件了：

$(function() {
    $('#results a').click(function() {
        // get the url of the page link
        var url = this.href;

        var page = ... extract the page parameter from the page link

        // update a hidden field inside the search form with this value
        $('#page').val(page);

        // trigger the search
        $('#searchForm').submit();

        // stop the link from navigating to the url it is pointing to
        return false;
    });
});
