Kendo UI 层次结构 children 模式

Question

关于 API 对 Kendo 的引用（证明：Kendo UI API Reference - Schema.Model.Children），children 节点可以在下一个方法中声明（参见嵌套 'schema'作为 'define options for second level'):

var datasource = new kendo.data.HierarchicalDataSource({
  data: [
    {
      categoryName: "SciFi",
      movies: [
        { title: "Star Wars: A New Hope", year: 1977, cast: [
            { actor: "Mark Hamill", character: "Luke Skywalker" },
            { actor: "Harrison Ford", character: "Han Solo" },
            { actor: "Carrie Fisher", character: "Princess Leia Organa" }
        ] },
        { title: "Star Wars: The Empire Strikes Back", year: 1980, cast: [
            { actor: "Mark Hamill", character: "Luke Skywalker" },
            { actor: "Harrison Ford", character: "Han Solo" },
            { actor: "Carrie Fisher", character: "Princess Leia Organa" },
            { actor: "Billy Dee Williams", character: "Lando Calrissian" }
        ] }
      ]
    }
  ],
  schema: {
    model: {
      children: { // define options for second level
        schema: {
          data: "movies",
          model: {
            children: "cast" // third level is defined by the field "cast"
          }
        }
      }
    }
  }
});

我对 HierarchicalDataSource 使用类似的定义并以这种方式获得 children 个节点：

schema: {
  model: {
    id: "urb_fltr",
    hasChildren: true,
    children: "PhoneCalls" // <- here is definition for children that are - data from field of output (next in parse)
  },
  parse: function (data) {
    var outRes = [];
    var dataRes = [];
    var tmpLoop = 0;
    var bordNum = 251170009;

    if (data.d.results != null && data.d.results.length > 0)
      for (var step = 0; step < data.d.results.length; step++) {

        if (data.d.results[step] == null) continue;

        var stepData = data.d.results[step];

        var stepValue = (stepData.urb_subject != null) ? stepData.urb_subject.Value : 0;

        var arrValue = (stepValue > bordNum) ? stepValue - bordNum : 0;

        if (outRes[arrValue] == null || typeof (outRes[arrValue]) == 'undefined') {
          outRes[arrValue] = {};
          outRes[arrValue].urb_total = 1;
          outRes[arrValue].urb_clnts = 0;

          outRes[arrValue].OwnerId = stepData.OwnerId;
          outRes[arrValue].urb_subjectValue = stepValue;

          outRes[arrValue].PhoneCalls = []; // <- children
        }
        else
          outRes[arrValue].urb_total += 1;
        // fill children field
        outRes[arrValue].PhoneCalls[outRes[arrValue].urb_total - 1] = {};
        outRes[arrValue].PhoneCalls[outRes[arrValue].urb_total - 1].CallId = stepData.ActivityId;
        outRes[arrValue].PhoneCalls[outRes[arrValue].urb_total - 1].urb_name = stepData.urb_name;
        outRes[arrValue].PhoneCalls[outRes[arrValue].urb_total - 1].CreatedOn = stepData.CreatedOn;
        outRes[arrValue].PhoneCalls[outRes[arrValue].urb_total - 1].PhoneNumber = stepData.PhoneNumber;
        outRes[arrValue].PhoneCalls[outRes[arrValue].urb_total - 1].ScheduledEnd = stepData.ScheduledEnd;

        if (stepData.RegardingObjectId != null && stepData.RegardingObjectId.Id != null && stepData.RegardingObjectId.LogicalName == "lead") {
           outRes[arrValue].PhoneCalls[outRes[arrValue].urb_total - 1].RegardingObjectId = stepData.RegardingObjectId;
        outRes[arrValue].urb_clnts += 1;
        }
      }

      for (var loop = 0; loop < outRes.length; loop++)
         if (typeof (outRes[loop]) != 'undefined') {
             outRes[loop].urb_subjectName = outRes[loop].urb_subjectName + " ( " + outRes[loop].urb_total + " - " + outRes[loop].urb_clnts + " )";
             dataRes[tmpLoop] = outRes[loop];
             tmpLoop++;
         }

       return dataRes; //data.d.results;
    },
    type: "json"
}

没关系。我可以这样看children。但默认情况下，'hasChildren' 的属性是 'true' 并且我为 children 节点添加方案，如 API 参考：

children: { // <- instead of "PhoneCalls" - next 'schema'
  schema: {
    data: "PhoneCalls",
    model: { hasChildren: false }
  }
}

，相当输children.

谁能帮助正确定义 children 属性方案？

Answer 1

只设置treeview的数据即可，无需定义schema即可。

data = [{id: '1', text: 'Music', items: [{id: '1.1', text: 'Country', items: []}, {id: '1.2'，文本：'Jazz'，项目：[]}]}]；

$("#treeView").data("kendoTreeView").dataSource.data(数据);

Answer 2

解决方法： 1. 忘记 'children' 中的 'schema' 大括号 - 返回 "PhoneCalls" 字符串值。 2、在'PhoneCall'对象中添加'hasChildren'属性（来自"PhoneCalls"集合），并在'false'.

中设置值

如果要添加新级别的树视图： 1.在'true'中设置'hasChildren'属性个"PhoneCall"个对象 2. 添加从属集作为"PhoneCall"个对象的属性 3. 在 "PhoneCall" 对象中添加 'children' 属性这将是一个字符串值 - 来自 p 的集合属性的名称。 2
