设置Kendo UI Grid的默认过滤器

标签: javascript kendo-ui kendo-grid

我有一个用javaScript渲染的Kendo UI网格。我希望字符串列有一个选项(“包含”)而没有第二个过滤器。到目前为止,我写的很好,

        $("#MyGrid").kendoGrid({
            // other bits of configuration here
            filterable: {
                extra:false, 
                operators: {
                    string:{ contains: "Contains"}
                }
            },
            // more bits of configuration here
        });

作为网格定义的一部分。结果看起来很好(我只有一个选项,所以下拉是多余的)。

Filter as I defined

但是,无论如何,过滤器仍然执行equals操作而不是contains操作(这是唯一可用的操作)。

我花了一段时间试图解决这个问题并且我一直在圈子里,因为我发现的代码要么不起作用,要么没有意义,或两者兼而有之。

有谁能告诉我如何将过滤器默认为“包含”而不是“等于”?

当您只有一个选项或者您对布局不满意时,您可以使用更高版本的Kendo中出现的“ui:func(element){}”重载来完全自定义过滤器控件(例如v2013 .1.319)

columns : [
    { field: "MyCity", width: 80, title : "City", filterable: customTextFilter },
    { field: "CreatedAt", width: 72, title: "Created", filterable: $scope.customDateFilter }
]

然后是自定义外观的函数:

var customTextFilter =
    {
        extra : false,
        operators : { string : { contains : "Contains"}},
        ui : function( element )
        {
            var parent = element.parent();
            while( parent.children().length > 1 )
                $(parent.children()[0]).remove( );

            parent.prepend( "<input data-bind=\"value:filters[0].value\" class=\"k-textbox\" type=\"text\">" );
        }
    }

以下是具有GTE / LTE格式的两个日期框的示例:

var customDateFilter =
    {
        extra : true,
        operators : { },
        ui : function( element )
        {
            var parent = element.parent();
            while( parent.children().length > 1 )
                $(parent.children()[0]).remove( );

            parent.prepend(
                "On or after:<br/><span class=\"k-widget k-datepicker k-header\">" +
                "<span class=\"k-picker-wrap k-state-default\">" +
                "<input data-bind=\"value:filters[0].value\" class=\"k-input\" type=\"text\" data-role=\"datepicker\"" +
                " style=\"width: 100%\" role=\"textbox\" aria-haspopup=\"true\" aria-expanded=\"false\" aria-disabled=\"false\" " +
                " aria-readonly=\"false\" aria-label=\"Choose a date\">" +
                "<span unselectable=\"on\" class=\"k-select\" role=\"button\">" +
                "<span unselectable=\"on\" class=\"k-icon k-i-calendar\">select</span></span></span></span>" +

                "<br/>On or before:<br/>" +
                "<span class=\"k-widget k-datepicker k-header\"><span class=\"k-picker-wrap k-state-default\">" +
                "<input data-bind=\"value: filters[1].value\" class=\"k-input\" type=\"text\" data-role=\"datepicker\"" +
                " style=\"width: 100%\" role=\"textbox\" aria-haspopup=\"true\" aria-expanded=\"false\" " +
                " aria-disabled=\"false\" aria-readonly=\"false\" aria-label=\"Choose a date\">" +
                "<span unselectable=\"on\" class=\"k-select\" role=\"button\">" +
                "<span unselectable=\"on\" class=\"k-icon k-i-calendar\">select</span></span></span></span>"
            );
        }
    };

显然你可以模板化你喜欢并为Date,Boolean等创建不同的自定义过滤器 - 请注意,对于上面的Date版本,如果要正确设置运算符,请说“gte”和“lte”用于过滤器[0] .operator和filter [1] .operator你可以在dataSource.filter属性上设置它,如下所示:

    dataSource: {
        transport :
        {
            read : function( context )
            {
                //note that here context.filter.filters has the array
                //of applied filters -- you can write a custom RESTful call
                //such as angular $http.get( ) or use Kendo native format to
                //send filter options to server.
            }
        },
        //filter settings here initialize filter[0], filter[1], etc.
        filter : [ 
           { field : "CreatedAt", operator : "gte" },
           { field : "CreatedAt", operator : "lte" }]
   }

更改实例的 所有 的默认运算符的最佳方法:

kendo.ui.FilterMenu.prototype.options.operators =           
  $.extend(kendo.ui.FilterMenu.prototype.options.operators, {
  string: {
      contains: "Contains",
      startswith: "Starts with",
      eq: "Is equal to",
      neq: "Is not equal to",
      doesnotcontain: "Does not contain",
      endswith: "Ends with"
  }
});

和完整的脚本:

kendo.ui.FilterMenu.prototype.options.operators =           
  $.extend(kendo.ui.FilterMenu.prototype.options.operators, {

/* FILTER MENU OPERATORS (for each supported data type) 
 ****************************************************************************/   
  string: {
      contains: "Contains",
      startswith: "Starts with",
      eq: "Is equal to",
      neq: "Is not equal to",
      doesnotcontain: "Does not contain",
      endswith: "Ends with"
  },
  number: {
      eq: "Is equal to",
      neq: "Is not equal to",
      gte: "Is greater than or equal to",
      gt: "Is greater than",
      lte: "Is less than or equal to",
      lt: "Is less than"
  },
  date: {
      eq: "Is equal to",
      neq: "Is not equal to",
      gte: "Is after or equal to",
      gt: "Is after",
      lte: "Is before or equal to",
      lt: "Is before"
  },
  enums: {
      eq: "Is equal to",
      neq: "Is not equal to"
  }
 /***************************************************************************/   
});

尝试更新到最新的内部版本。版本高于 2012.3.1304 的版本应包含修复程序。

我遇到了同样的问题而且我得到了它,它需要 .Clear()选项!

我正在使用Razor中的MVC Wrapper构建我的网格:

@(Html.Kendo().Grid<LocationViewModel>()
    .Name("locationGrid")
    // other bits of configuration here
    .ColumnMenu()
    .Filterable(f => f.Operators(o => o.ForString(s => s
        .Clear()
        .Contains("Contains")
        .DoesNotContain("Does not contain")
        .EndsWith("Ends with")
    )))
    // other bits of configuration here
)

<强>要点:

  1. .Clear()是必需的!
  2. 排序是必要的!将.Contains()放在.Clear()之后,然后默认为包含!
  3. 其他信息: 我正在使用Kendo UI 2013.1.514
