layui dtree ajax,layui中使用dtree插件数据无法正常显示-优快云博客

在使用layui的dtree插件时遇到数据无法正常显示的问题。检查发现数据格式需与示例匹配，包括'id'、'title'、'parentId'等字段。示例数据中包含'checkArr'字段，而提供的数据格式中缺少该字段。为解决此问题，需确保返回的JSON数据中包含所有必需字段，以保证dtree正确渲染。

layui中使用dtree插件数据无法正常显示

检查自己返回的josn数据格式和dtree需要的数据是否相同

示例格式：

{

"code":0,

"msg":"操作成功",

"data":[

{"id":"001","title": "湖南省", "spread":true, "parentId": "0","checkArr": "{\"type\": \"0\", \"checked\": \"0\"}"},

{"id":"002","title": "湖北省","spread":false, "parentId": "0","checkArr": "{\"type\": \"0\", \"checked\": \"0\"}"},

{"id":"001001", "title": "长沙市", "parentId": "001","checkArr": "{\"type\": \"0\", \"checked\": \"0\"}"},

{"id":"001002", "title": "株洲市", "parentId": "001" ,"checkArr": "{\"type\": \"0\", \"checked\": \"0\"}"},

{"id":"001003", "title": "湘潭市", "parentId": "001" ,"checkArr": "{\"type\": \"0\", \"checked\": \"0\"}"},

{"id":"001004","title": "衡阳市", "parentId": "001","checkArr": "{\"type\": \"0\", \"checked\": \"0\"}"},

{"id":"001005","title": "郴州市","parentId": "001","checkArr": "{\"type\": \"0\", \"checked\": \"0\"}"},

{"id":"002001","title": "武汉市","parentId": "002","checkArr": "{\"type\": \"0\", \"checked\": \"0\"}"},

{"id":"002002","title": "黄冈市","parentId": "002","checkArr": "{\"type\": \"0\", \"checked\": \"0\"}"},

{"id":"002003","title": "荆州市","parentId": "002","checkArr": "{\"type\": \"0\", \"checked\": \"0\"}"},

{"id":"002004","title": "天门市","parentId": "002","checkArr": "{\"type\": \"0\", \"checked\": \"0\"}"},

{"id":"002005","title": "孝感市","parentId": "002","checkArr": "{\"type\": \"0\", \"checked\": \"0\"}"}

]

}

我的数据格式

@JsonProperty(value = "parentId")

private Integer pid;

private String title;

private String icon;

private String href;

private String target;

private Boolean spread;

public String getCheckArr() {

return checkArr;
