在kendo中使用列自己的值填充列的筛选器值

{
    field: "columnName",
    title: "Column Name",
    template: '<input type="text" class="k-textbox" data-bind="value: columnNameFilter" />'
}

{
    field: "columnName",
    title: "Column Name",
    template: '<input type="text" class="k-textbox" data-bind="value: columnNameFilter" />',
    filterable: {
        cell: {
            operator: "eq",
            template: function (args) {
                args.element.kendoAutoComplete({
                    dataSource: dataSource,
                    filter: "contains",
                    dataTextField: "columnName",
                    dataValueField: "columnName",
                    valuePrimitive: true
                });
            }
        }
    }
}

var viewModel = kendo.observable({
    columnNameFilter: "",
    dataSource: new kendo.data.DataSource({
        transport: {
            read: {
                url: "data.json",
                dataType: "json"
            }
        },
        filter: {
            logic: "and",
            filters: [
                { field: "columnName", operator: "eq", value: function () { return viewModel.columnNameFilter; } }
            ]
        }
    })
});
