对于我的剑道树视图,我将按需加载设置为true,但是没有按服务器加载子项,因为为数据源模型设置了'children'属性,即使它是空的。
homogeneous = new kendo.data.HierarchicalDataSource({
transport: {
read: {
type: 'POST',
contentType: "application/json; charset=utf-8",
url: obj.DataSourcesURL,
dataType: "json"
},
parameterMap: function (options) {
if (!options.Id) {
options.Id = null;
}
if (options.filter) {
options.Search = options.filter.filters[0].name;
}
else {
options.Search = '';
}
return JSON.stringify(options);
}
},
schema: {
data: "d",
errors: function (response) {
console.log(response);
console.log("errors");
},
model: {
hasChildren: "hasChild",
children:'items',
id: "Id"
}
}
});
树视图代码是
$treeView.kendoTreeView({
dataTextField: 'Description',
checkboxes: {
checkChildren: true
},
dataSource: homogeneous,
loadOnDemand: loadOnDemand,
check: function () {
var checkedNodes = [];
var treeView = $treeView.data("kendoTreeView");
getCheckedNodes(treeView.dataSource.view(), checkedNodes);
setMessage(checkedNodes.length);
},
dataBound: function (e) {
if (e !== undefined)
resetCheckedNodes(e.sender.dataItems());
},
messages: {
loading: "Laden..."
},
expand: function (e) {
var dataItem = this.dataItem(e.node);
}
});
答案 0 :(得分:0)
尝试在架构中设置hasChildren
:
schema: {
data: "d",
errors: function (response) {
console.log(response);
console.log("errors");
},
model: {
hasChildren: function(e) {
return e.items && e.items.length;
},
children:'items',
id: "Id"
}
}
而且从您的问题来看,我不确定您是否获得任何数据,或者只有Children
数据未被返回。也许您还可以展示您的数据结构的样子。
