如何在kendo schedular中绑定数据源

Question

试图在kendo schedular的自定义视图中连接多选，但它不显示数据源数据。来自服务器的数据&存储在资源内部。其他字段显示正常。有人能帮我解决这个问题吗？

数据源

$scope.attendeesDS = new kendo.data.DataSource({
        type: "odata",
        transport: {
            read:
            {
                url: "odata/AttendeesOData",
                dataType: "json"
            }
        },
        schema: {
            data: function(data) {
                return data["value"];
            },
            total: function(data) {
                return data["odata.count"];
            },
            model: {
                fields: {
                    value: { from: "Id", type: "number" },
                    text: { from: "text", type: "string" },
                    color: { from: "color", type: "string" }
                }
            }
        },
        serverPaging: true,
        serverSorting: true,
        serverFiltering: true,
        pageSize: 15
    });

                multiple: true,
                dataTextField: "text",
                dataValueField: "id",

                nullable: true
            }
        ]
    });

自定义模板中的多选

<div class="k-edit-label">
    <label for="Attendees">Tutors</label>
</div>
<div data-container-for="Attendees" class="k-edit-field">
    <select id="Attendees" multiple="multiple" name="Attendees"
            data-role="multiselect"
            data-bind="value: attendees"
            data-source="attendees"
            data-text-field="text"
            data-value-field="id"
            data-value-primitive="true"></select>
</div>

Answer 1

首先，你选择数据源的方式，嗯，我不认为它是正确的，改用这种方式：

您需要添加编辑事件，以便可以将数据源添加到计划程序上的可编辑模板。

edit: function(e) {
            debugger;
            var ownerId = e.container.find("#ownerId").data("kendoDropDownList");
            var attendeesId = e.container.find("#attendeesId").data("kendoMultiSelect");
            //bind the widget to the resouces
            ownerId.dataSource.data(e.sender.resources[0].dataSource.data());
            attendeesId.dataSource.data(e.sender.resources[1].dataSource.data());
          }

我已经修改了调度器的kendo dojo示例，当您编辑调度器的事件时，它将使用自定义的可编辑模板并添加多选

我还修改了kendo示例，并在其自定义模板中添加了multiselect，

<div data-container-for="attendeesId" class="k-edit-field">
            <select id="attendeesId" data-bind="value:attendeesId" data-role="multiselect" data-value-field="id" data-text-field="name"/>
    </div>

并修改资源数据

resources: [
            {
              field: "ownerId",
              title: "Owner",
              dataSource: [
                { text: "Alex", value: 1, color: "#f8a398" },
                { text: "Bob", value: 2, color: "#51a0ed" },
                { text: "Charlie", value: 3, color: "#56ca85" }
              ]
            },{ 
              field: "attendeesId",
              title: "Attendees",
              dataSource:[
                            {name:"Brown",id:"1"},
                            {name:"Daniel",id:"2"},
                            {name:"John",id:"3"},
                            {name:"Hawk",id:"4"},
                            {name:"Borne",id:"6"},
                            {name:"Deryl",id:"7"},
                            {name:"Jack",id:"8"}
                            ]
            }

          ],

编辑:关于你的评论：“我在你的例子中看不到在模型中定义了attendeesId &我如何获得已经选择的与会者。”

假设您想要存储数据类型为对象数组的多选，我已经了解到目前kendo模型不能根据kendo forum处理复杂的数据类型，如对象或数组，因此解决此问题的方法参考此link。您可以将其存储在单独的kendo observable上，并将可观察对象绑定到添加了此kendo.bind(e.container.find("#attendeesId"), viewModel);的multiselect on edit函数。还要看一下参数映射，我在其中检索selectedAttendees，然后将其添加到option.model中，然后继续保存/更新到服务器的过程

if (operation !== "read" && options.models) {
    if(typeof options.models !== "undefined"){
      options.models[0].selectedAttendees = viewModel.selectedAttendees;
      console.log("the models here :",options.models);
    }
    return {models: kendo.stringify(options.models)};
}

我还修改了这个新kendo dojo上的示例，您可以看到options.models的控制台日志现在具有selectedAttendees属性。
