在我看来,我有可能使用返回部分视图的Ajax.BeginForm
来过滤显示的数据,并仅刷新包含数据的表。使用Ajax.ActionLink
单击列标题时,我也可以按列排序。问题在于,当我使用Ajax.ActionLink
时,我必须刷新整个页面并且松开在过滤器中选择的内容(它们是自定义多选组合控件),因此整个数据被排序和显示。
我尝试使用ViewBag
发送Json数据以阻止过滤器,但我失败了。我宁愿只在排序时刷新表。我是MVC的新手。
如何以一种很好的方式做到这一点?谢谢你的帮助!
查看:
@using (Ajax.BeginForm(new AjaxOptions() {HttpMethod = "get", InsertionMode = InsertionMode.Replace, UpdateTargetId = "exposureRecords"}))
{
<div class="form-group">
<select id="brands-select" name="brands" multiple="multiple">
@{
var brands = Model.Brands;
foreach (var item in brands)
{
<option value="@item">@item</option>
}
}
</select>
</div>
(...similar for 3 other filters...)
<table class="table">
<tr>
<th>
@Html.ActionLink("Marka", "Index", new { sortOrder = ViewBag.BrandSortParam })
</th>
<th>
@Html.ActionLink("Dyscyplina", "Index", new { sortOrder = ViewBag.DisciplineSortParm })
</th>
<th>
@Html.ActionLink("Miesiąc", "Index", new { sortOrder = ViewBag.MonthSortParm })
</th>
<th>
@Html.ActionLink("Liczba ekspozycji", "Index", new { sortOrder = ViewBag.QuantitySortParm })
</th>
<th>
@Html.ActionLink("Ekwiwalent reklamowy", "Index", new { sortOrder = ViewBag.ValueSortParm })
</th>
</tr>
</table>
}
@Html.Partial("_Table",Model)
然后在控制器中我有
public ActionResult Index(IEnumerable<string> brands, IEnumerable<string> disciplines,
IEnumerable<string> months,string sortOrder)
{
ViewBag.BrandSortParam = String.IsNullOrEmpty(sortOrder) ? "brand_desc" : "";
ViewBag.DisciplineSortParm = sortOrder == "discipline" ? "discipline_desc" : "discipline";
ViewBag.MonthSortParm = sortOrder == "month" ? "month_desc" : "month";
ViewBag.QuantitySortParm = sortOrder == "quantity" ? "quantity_desc" : "quantity";
ViewBag.ValueSortParm = sortOrder == "value" ? "value_desc" : "value";
model.ExposureRecords = FilterExposure(brands, disciplines, months);
model.ExposureRecords = Sort(sortOrder, model.ExposureRecords);
if (Request.IsAjaxRequest())
return PartialView("_Table", model);
return View(model);
}

我的建议是使用客户端库。排序可以在控制器中完成,但根据我的经验,它通常很痛苦。我最近在使用sorttable.js的项目中完成了您想要完成的任务,尽管有多种选择可供选择(请参阅Porschiey上面的评论)。
要使用sortable,请添加&#34; sortable&#34;你的桌子上课。另外,一定要运行&#34;可销售&#34; js使用ajax.beginform ajaxoptions中的OnComplete属性,这样表将在ajax调用后排序。像这样:
@using (Ajax.BeginForm(new AjaxOptions() {HttpMethod = "get", InsertionMode = InsertionMode.Replace, UpdateTargetId = "exposureRecords", OnComplete="makesortable"}))
{
...
}
function makesortable() {
sorttable.makeSortable(document.getElementById('exposureRecords'));
};
