这是我的问题。我有一个具有大量搜索条件的 SearchViewModel
,这些值根本不适合 URL。我目前正在使用 Troy Goode 的 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种选择,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的参数,这是一个很好的解决方案。
搜索 View 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; }
}
最佳答案
我对这样的控件不熟悉。我认为最简单的方法是使用 javascript 劫持寻呼机 anchor 上的点击,并通过取消由 anchor 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;
});
});
