推荐答案

HierarchicalDataSource schema.model对象的配置字段称为

There is a configuration field of the HierarchicalDataSource schema.model object called hasChildren you can add a boolean property to your model which indicates if the your model has items.

这样，当TreeView创建其元素时，它将检查该属性(或调用该函数-例如，如果items.leght大于零，则可以返回)，并且如果返回的值为false，则不会创建展开箭头在项目前面.

This way when the TreeView creates its elements it will check that property (or call the function - you could for example return if the items.leght is greater than zero) and if the returned value is false it wont create the expand arrow in front of the item.

检查此演示.
