Question

关于Kendo的API参考（证明：Kendo UI API Reference - Schema.Model.Children），子节点可以在下一种方法中声明（参见嵌套'schema'作为'第二级的定义选项'）：

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，并以这种方式获取子节点：

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。我可以这样看待孩子们。但默认情况下，'hasChildren'的属性为'true'，我为子节点添加方案，如API参考：

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

，并且非常失去孩子。

任何人都可以帮助正确定义带有方案的子属性吗？

Answer 1

您只需设置树视图的数据，就可以在不定义架构的情况下完成。

data = [{id：＆＃39; 1＆＃39;，text：＆＃39; Music＆＃39;，items：[{id：＆＃39; 1.1＆＃39;，text：＆＃39 ;国家＆＃39;，项目：[]}，{id：＆＃39; 1.2＆＃39;，文字：＆＃39; Jazz＆＃39;，项目：[]}]}];

$（＆＃34;＃树形目录＆＃34）的数据。（＆＃34; kendoTreeView＆＃34）dataSource.data（数据）;

解决方案： 1.忘记＆＃39;架构＆＃39;支撑儿童＆＃39; - 转回＆＃34; PhoneCalls＆＃34;字符串值。 2.添加＆＃39; hasChildren＆＃39; “电话呼叫”中的财产。对象（来自＆＃34; PhoneCalls＆＃34;设置）并将值设置为＆＃39; false＆＃39;。

如果要添加新级别的树视图： 1.设置＆＃39; hasChildren＆＃39; ＆＃34; PhoneCall＆＃34;的财产对象＆＃39; true＆＃39; 2.将从属集添加为＆＃34; PhoneCall＆＃34;的属性。对象 3.添加孩子＆＃39;属于＆＃34; PhoneCall＆＃34;可以是字符串值的对象 - 来自p的set属性的名称。 2
