easyUI关于使用tree结果不出现文本信息，只出现图片

Question

楼主在练习easyUI学习自己生成一个树，结果发现把js写好之后运行只出现了树形的图标，不出现文本信息如下图：后来我给tree添加了checkbox属性，结果当选中一个节点的时候然后alert这个节点，弹出的也是null，求解这是为何呀！

var node = $('#treeTab').tree('getSelected');
 alert(node);

 

底下贴出我的json文件的截图

这是我的json文件

[{
	"id":1,
	"name":"C",
	"size":"",
	"date":"02/19/2010",
	"children":[{
		"id":2,
		"name":"Program Files",
		"size":"120 MB",
		"date":"03/20/2010",
		"children":[{

Answer 1

问题解决了是楼主的文件有问题，还发现了一点：

1.如果checkbox属性为true选择选中的节点使用getChecked方法，然后根据[]下标取得对应的节点信息
2.如果checkbox属性为false选择选中的节点使用getSelected方法得到选择的节点

Answer 2

name 换成text

Answer 3

哪位知道怎么回事能不能帮这看下呀，这个情况是个啥意思呢

Answer 4

文本的属性为text  

[{
    "id": 1,
    "text": "Node 1",
    "state": "closed",
    "children": [{
        "id": 11,
        "text": "Node 11"
    },{
        "id": 12,
        "text": "Node 12"
    }]
},{
    "id": 2,
    "text": "Node 2",
    "state": "closed"
}]
