combotree 的简单使用

一、前端

combotree HTML:

<input id="201711281652407353448711985811" class="easyUI-combotree"  params="width:150px"/>

为树控件赋值js:(可多选时需要添加:multiple: true, 属性)

            $('#'+cus).combotree({    
                url:'${ctx}/secondPhase/customCombotreeData.pt?id='+cus,
//multiple: true,  });

获取树节点数据js:

    source_detail = $('#201711281652407353448711985811').combotree('getValue');
    alert(source_detail);

二、后台

根据API,combotree需要的json数据主要有三个关键属性:id、text、children。

我们new一个类作为树的模型:

public class comboTreeModel {
    private String id;
    private String text;
    private List<comboTreeModel> children;
        
    //set and get
}

url请求数据获取与处理:

    @RequestMapping("customCombotreeData")
    @ResponseBody
    public List customCombotreeData(){
        Dmp dmp = this.getParamsAsDmp();
        /*得到第一级菜单的集合,
         * [{id=A, text=A省市重点工作}, {id=B, text=B区主要领导批示和主要领导会议布置的重点工作}, {id=C, text=C一般性工作}, {id=D, text=D各局委办工作}]
         */
        List li = service.customComboboxData(dmp);
        
        //新建一个树形list用来把村树结构:id、text、children
        List<comboTreeModel> fatherList = new ArrayList<comboTreeModel>();
        for (int i = 0; i < li.size(); i++) {
            //树节点是一个一个父子节点添加,因此父节点模型要放在for循环里面,每次添加都是一个新的节点
            comboTreeModel fatherModel = new comboTreeModel();
            Map map = (Map) li.get(i);
            String id = (String) map.get("id");
            String text = (String) map.get("text");
            //向父模型里面添加一级菜单
            fatherModel.setId(id);
            fatherModel.setText(text);
            
            dmp.put("fieldcode", id);
            //用父id获取子集合
            //[{id=A1, text=A1省市重点工作}, {id=A2, text=A2市政府绩效指标}, {id=A3, text=A3市领导批示}]
            List fli = service.se_feileiTree(dmp);
            //新建一个子树形集合
            List<comboTreeModel> sonList = new ArrayList<comboTreeModel>();
            for (int j = 0; j < fli.size(); j++) {
                //新建子树形模型
                comboTreeModel sonModel = new comboTreeModel();
                Map map2 = (Map) fli.get(j);
                String sonid = (String) map2.get("id");
                String sontext = (String) map2.get("text");
                //向子模型添加数据,这里只有两级,有三级的话,该级菜单可以继续添加children
                sonModel.setId(sonid);
                sonModel.setText(sontext);
                //把子模型添加到子二级菜单结合。
                sonList.add(sonModel);
            }
            //再父模型数据循环最后,同时把循环整理的子二级菜单集合添加到父一级菜单模型的children。
            fatherModel.setChildren(sonList);
            //把整理好的父级(已经包含子级菜单)模型添加到要返回的树形集合
            fatherList.add(fatherModel);
        }
        return fatherList;
    }

三、数据库数据以及返回json数据参考

     

返回整理后的json数据:

[{
    "id": "A",
    "text": "A省市重点工作",
    "children": [{
        "id": "A1",
        "text": "A1省市重点工作",
        "children": null
    },
    {
        "id": "A2",
        "text": "A2市政府绩效指标",
        "children": null
    },
    {
        "id": "A3",
        "text": "A3市领导批示",
        "children": null
    }]
},
{
    "id": "B",
    "text": "B区主要领导批示和主要领导会议布置的重点工作",
    "children": [{
        "id": "B1",
        "text": "B1党委政府会议纪要",
        "children": null
    },
    {
        "id": "B2",
        "text": "B2政府会议纪要",
        "children": null
    },
    {
        "id": "B3",
        "text": "B3主要领导批示指示",
        "children": null
    },
    {
        "id": "B4",
        "text": "B4区重大项目",
        "children": null
    },
    {
        "id": "B5",
        "text": "B5其他",
        "children": null
    }]
},
{
    "id": "C",
    "text": "C一般性工作",
    "children": [{
        "id": "C1",
        "text": "C1区各项重点工作",
        "children": null
    },
    {
        "id": "C2",
        "text": "C2区分管领导专项督查",
        "children": null
    },
    {
        "id": "C3",
        "text": "C3区属绩效指标",
        "children": null
    },
    {
        "id": "C4",
        "text": "C4其他",
        "children": null
    }]
},
{
    "id": "D",
    "text": "D各局委办工作",
    "children": [{
        "id": "D1",
        "text": "D1各局委办工作",
        "children": null
    }]
}]
