我正在使用kendo ui树列表组件,并从远程源获取数据。数据源定义为:
$("#location-manage-grid").kendoTreeList({
dataSource: new kendo.data.HierarchicalDataSource({
transport: {
read: {
url: "api/getLocation",
dataType: "json"
}
},
schema: {
model: {
id: "id",
location: "location",
hierarchy: "hierarchy",
hasChildren: "hasChildren",
map: "map"
}
}
}),
height: 600,
pageable: true,
columns: [
{ field: "hierarchy", title: "Hierarchy", width: 250 },
{ field: "location", title: "location", width: 250 },
{ field: "map", title: "map", width: 250 },
{ title: "Edit", command: [ "edit", "destroy" ], width: 250, attributes: { style: "text-align: center;" } }
]
});
数据源url的响应是
[{"hasChildren":true,"hierarchy":"Kendo ui","location":"New York","id":1,"map":true}]
然而,当我运行应用程序时,它出现了一个错误,上面写着:
未捕获的类型错误:无法读取未定义的属性"toLowerCase"
我已经检查了模式定义,真的找不到哪里出了问题。有人知道为什么吗?
我发现我犯了什么错误,我应该使用TreeListDataSource
而不是HierarchicalDataSource
,这是主要原因。
