在GridMVC中创建自定义时间小部件

Question

我正在尝试创建时间小部件，以便在网格MVC中按时间过滤记录。我可以看到控件，但它不过滤任何记录。这是剧本。我添加了mvc网格的脚本、视图代码和索引页。

脚本

function TimeWidget() {
this.getAssociatedTypes = function () {
    return ["TimeFilterWidget"];
};
this.onShow = function () {
};
this.showClearFilterButton = function () {
    return true;
};
this.onRender = function (container, lang, typeName, values, cb, data) {
    //store parameters:
    this.cb = cb;
    this.container = container;
    this.lang = lang;
    //this filterwidget demo supports only 1 filter value for column column
    this.value = values.length > 0 ? values[0] : { filterType: 1, filterValue: "" };
    this.renderWidget(); //onRender filter widget
    //this.loadCustomers(); //load customer's list from the server
    this.registerEvents(); //handle events
};
this.renderWidget = function () {
    var html = '<p>Select Time to filter:</p>
                <p><input class="time" type="time" id="tminput"/></p>
                ';
    this.container.append(html);
};
this.registerEvents = function () {                
    var x = document.getElementById("tminput");
    x.addEventListener("blur", myBlurFunction, true);        
};
function myBlurFunction() {
    var $context = this;
    var values = [{ filterValue: $(this).val(), filterType: 1 /* Equals */ }];        
    $context.cb(values);
}
}

网格视图

@using GridMvc.Html
@using GridMvc.Sorting
@model IEnumerable<GridMvc.Site.Logging>
@Html.Grid(Model).Named("ordersGrid").Columns(columns =>
{
    /* Adding "OrderID" column: */
    columns.Add(o => o.ID)
           .Titled("Number")
           .SetWidth(100);
    columns.Add(o => o.DateTime, "Date")
            .Titled("Date")
            .SortInitialDirection(GridSortDirection.Descending)
            .Format("{0:dd/MM/yyyy}")
            .SetWidth(110);
    columns.Add(o => o.DateTime, "Time")
            .Titled("Time")
            .SortInitialDirection(GridSortDirection.Descending)
            .Format("{0:hh:mm tt}")                
            .SetWidth(110)
            .SetFilterWidgetType("TimeFilterWidget");
    columns.Add(o => o.Type)
           .Titled("Type")
           .SetWidth(150)
           .ThenSortByDescending(o => o.ID)
           .SetFilterWidgetType("TypeFilterWidget");
    columns.Add(o => o.Description)
           .Titled("Description")
           .SetWidth(250);
    columns.Add(o => o.Reference)
            .Titled("Reference")
            .SetWidth(150)
            .Css("hidden-xs"); //hide on phones
    columns.Add(o => o.Response)
            .Titled("Response")
            .SetWidth(150)
            .Css("hidden-xs"); //hide on phones        

}).WithPaging(15).Sortable().Filterable().WithMultipleFilters()

索引视图

<script>
$(function () {
    pageGrids.ordersGrid.addFilterWidget(new TypeWidget());
    pageGrids.ordersGrid.addFilterWidget(new TimeWidget());
});
</script>

如果这样可能会有所帮助。把你在网格上的代码添加到页面上。.Named（"ordersGrid"）示例代码：

@Html.Grid(Model).Named("ordersGrid").Columns(columns =>
{
    columns.Add(o => o.Customer.CompanyName)
           .Titled("Company")
           .SetWidth(250)
           .ThenSortByDescending(o => o.OrderID)
           .Filterable(true)
           .SetFilterWidgetType("CustomCompanyNameFilterWidget"); })

此nead for work JavaScrip方法在文件gridmvc.customwidgets.js 中添加FilterWidget

我希望它能帮助到别人。
