Easyui 异步树的实现 - zziy

网上最多的onBeforeExpand 可用，因为后台代码没写对导致树形结构重复加载数据

前端代码：

 1 <%@ page language="java" contentType="text/html; charset=UTF-8"
 2     pageEncoding="UTF-8"%>
 3     <div>
 4         <table cellpadding="5">
 5             <tr>
 6                 <td height="300px"><ul id="diseaseNameTree" class="easyui-tree"></ul>
 7                 </td>
 8             </tr>
 9         </table>
10     </div>
11 <script>
12     $('#diseaseNameTree').tree({
13         url : getServer_context() + '/api/patient/getDiseaseNameTree?Id=',
14         onBeforeExpand : function(node, param) {
15             console.log('ID=' + node.id);
16             console.log('length=' + node.id.length);
17             $('#diseaseNameTree').tree('options').url = getServer_context() + '/api/patient/getDiseaseNameTree?Id=' + node.id;
18         }
19     })
20                     
21     function searchICD10ByPinyin() {
22         var pinyin = $('#ICD10Pinyin').val();
23         console.log(pinyin);
24         if (pinyin == null || pinyin == "") {
25             $('#diseaseNameTree').tree('reload');
26         } else {
27             console.log('000');
28             $('#diseaseNameTree').tree({
29                 url: getServer_context() + '/api/patient/getDiseaseNameByPinyin?Pinyin=' + pinyin
30             });
31         }
32 
33     }
34 </script>

后台代码：

 1     public JSONArray getDiseaseNameTreeData(String Id) throws RecordNotFoundException {
 2         JSONArray jsonArray = new JSONArray();
 3         JSONArray childrenArray = new JSONArray();
 4         JSONArray grandChildrenArray = new JSONArray();
 5         JSONObject parentObject = new JSONObject();
 6         JSONObject childrenObject = new JSONObject();
 7         JSONObject grandChildrenObject = new JSONObject();
 8         
 9         if(Id == null || "".equals(Id)) {
10             Iterable<SsIcd10> parentList = ssICD10Dao.getDiseaseNameParent();
11             for(SsIcd10 parent : parentList) {
12                 parentObject.clear();
13                 parentObject.put("id", parent.getFicd10());
14                 parentObject.put("text", parent.getFdesc());
15                 parentObject.put("state", "closed");
16                 jsonArray.add(parentObject);
17             }
18             return jsonArray;
19         } else if (Id.length() == 3){
20             Iterable<SsIcd10> childrenList = ssICD10Dao.gettDiseaseNameChildren(Id);
21             for(SsIcd10 child : childrenList) {
22                 childrenObject.clear();
23                 childrenObject.put("id", child.getFicd10());
24                 childrenObject.put("text", child.getFdesc());
25                 childrenObject.put("state", ssICD10Dao.hasGrandChildren(child.getFicd10()) > 0 ? "closed" : "open");
26                 childrenArray.add(childrenObject);
27             }
28             return childrenArray;
29         } else {
30             Iterable<SsIcd10> grandChildrenList = ssICD10Dao.gettDiseaseNameGrandChildren(Id);
31             for(SsIcd10 grandChild : grandChildrenList) {
32                 grandChildrenObject.clear();
33                 grandChildrenObject.put("id", grandChild.getFicd10());
34                 grandChildrenObject.put("text", grandChild.getFdesc());
35                 grandChildrenArray.add(grandChildrenObject);
36             }
37             return grandChildrenArray;
38         }

逻辑写的很傻，还没想出来怎么写更好的

 1     public JSONArray getDiseaseNameTreeByPinyin(String Pinyin) throws RecordNotFoundException {
 2         JSONArray jsonArray = new JSONArray();
 3         JSONArray childrenArray = new JSONArray();
 4         JSONArray grandChildrenArray = new JSONArray();
 5         JSONObject parentObject = new JSONObject();
 6         JSONObject childrenObject = new JSONObject();
 7         JSONObject grandChildrenObject = new JSONObject();
 8         Iterable<SsIcd10> list = ssICD10Dao.getDiseaseNameDataByPinyin(Pinyin);
 9         for(SsIcd10 ssIcd10 : list) {
10             if(ssIcd10.getFicd10().length() == 3) {
11                 parentObject.clear();
12                 parentObject.put("id", ssIcd10.getFicd10());
13                 parentObject.put("text", ssIcd10.getFdesc());
14                 Iterable<SsIcd10> children =  ssICD10Dao.getDiseaseNameChildrenByPinyin(ssIcd10.getFicd10(), Pinyin);
15                 if(children != null) {
