【easyui】之treegrid的分頁

easyui官網給的treegrid的分頁是相當的復雜，我們來簡化一下！

首先treegrid 分頁和 datagrid一樣需要設置一系列參數！

 

如下:

 

depTreeGrid=$("#dep_tree_grid").treegrid({
            nowrap: true,
            fit : true,
            border : false,
            method:'GET',
            rownumbers: true,//顯示行號
            collapsible:true,//定義面板是否可以折疊
            loadMsg:"正在加載信息請稍候...",
            animate:true,
            url:ctxPath+"/sys/deps",            
            idField:'id',                //數據表格要有主鍵    
            treeField:'depName',            //treegrid 樹形結構主鍵 text
            fitColumns:true ,//表格自動適應
            striped:true,//隔行變色,
            pagination:true,//底部顯示工具欄組件
            pageSize:1,
            pageList:[1,20,30,40,50],//每頁顯示數
            sortName:'depSort',
            sortOrder:'asc',
            columns:[[
                {field:'depName',title:'部門名稱',width:200} ,
                {field:'remark',title:'部門描述路徑',width:120} ,
                {field:'depSort',title:'部門排序',width:120,sortable:true} ,
                {field:'createTime',title:'創建時間',width:120} ,
            ]],
            onLoadSuccess:function(data){ delete $(this).treegrid('options').queryParams['id']; },
            onContextMenu: function(e,row){
                e.preventDefault();                    //屏蔽瀏覽器的菜單
                $(this).treegrid('unselectAll');    //清除所有選中項
                $(this).treegrid('select', row.id);    //選中狀態 
                $('#dep').menu('show', {
                    left: e.pageX,
                    top: e.pageY
                });
            },
            toolbar: "#dep_tb",
        });
    });

 

翻頁返回的格式是

{"total":28,"rows":[
{"productid":"FI-SW-01","productname":"Koi","unitcost":10.00,"status":"P","listprice":36.50,"attr1":"Large","itemid":"EST-1"},
{"productid":"K9-DL-01","productname":"Dalmation","unitcost":12.00,"status":"P","listprice":18.50,"attr1":"Spotted Adult Female","itemid":"EST-10"},
{"productid":"RP-SN-01","productname":"Rattlesnake","unitcost":12.00,"status":"P","listprice":38.50,"attr1":"Venomless","itemid":"EST-11"},
{"productid":"RP-SN-01","productname":"Rattlesnake","unitcost":12.00,"status":"P","listprice":26.50,"attr1":"Rattleless","itemid":"EST-12"},
{"productid":"RP-LI-02","productname":"Iguana","unitcost":12.00,"status":"P","listprice":35.50,"attr1":"Green Adult","itemid":"EST-13"},
{"productid":"FL-DSH-01","productname":"Manx","unitcost":12.00,"status":"P","listprice":158.50,"attr1":"Tailless","itemid":"EST-14"},
{"productid":"FL-DSH-01","productname":"Manx","unitcost":12.00,"status":"P","listprice":83.50,"attr1":"With tail","itemid":"EST-15"},
{"productid":"FL-DLH-02","productname":"Persian","unitcost":12.00,"status":"P","listprice":23.50,"attr1":"Adult Female","itemid":"EST-16"},
{"productid":"FL-DLH-02","productname":"Persian","unitcost":12.00,"status":"P","listprice":89.50,"attr1":"Adult Male","itemid":"EST-17"},
{"productid":"AV-CB-01","productname":"Amazon Parrot","unitcost":92.00,"status":"P","listprice":63.50,"attr1":"Adult Male","itemid":"EST-18"}
]}

 

點擊tree請求返回的數據是

[
{"productid":"FI-SW-01","productname":"Koi","unitcost":10.00,"status":"P","listprice":36.50,"attr1":"Large","itemid":"EST-1"},
{"productid":"K9-DL-01","productname":"Dalmation","unitcost":12.00,"status":"P","listprice":18.50,"attr1":"Spotted Adult Female","itemid":"EST-10"},
{"productid":"RP-SN-01","productname":"Rattlesnake","unitcost":12.00,"status":"P","listprice":38.50,"attr1":"Venomless","itemid":"EST-11"},
{"productid":"RP-SN-01","productname":"Rattlesnake","unitcost":12.00,"status":"P","listprice":26.50,"attr1":"Rattleless","itemid":"EST-12"},
{"productid":"RP-LI-02","productname":"Iguana","unitcost":12.00,"status":"P","listprice":35.50,"attr1":"Green Adult","itemid":"EST-13"},
{"productid":"FL-DSH-01","productname":"Manx","unitcost":12.00,"status":"P","listprice":158.50,"attr1":"Tailless","itemid":"EST-14"},
{"productid":"FL-DSH-01","productname":"Manx","unitcost":12.00,"status":"P","listprice":83.50,"attr1":"With tail","itemid":"EST-15"},
{"productid":"FL-DLH-02","productname":"Persian","unitcost":12.00,"status":"P","listprice":23.50,"attr1":"Adult Female","itemid":"EST-16"},
{"productid":"FL-DLH-02","productname":"Persian","unitcost":12.00,"status":"P","listprice":89.50,"attr1":"Adult Male","itemid":"EST-17"},
{"productid":"AV-CB-01","productname":"Amazon Parrot","unitcost":92.00,"status":"P","listprice":63.50,"attr1":"Adult Male","itemid":"EST-18"}
]

 

 

在點擊 treegrid 會傳一個id，所以在后端處理的時候，根據id來做處理

 

@GetMapping
    @ResponseBody
    public Object list(int page,int rows,String sort,String order,
            @RequestParam Map<String,Object>  params,@RequestParam(defaultValue="0") String id ){
        if("0".equals(id)){
            PageInfo pageInfo = new PageInfo(page,rows, sort, order);
            params.put("id", id);
            pageInfo.setCondition(params);
            return sysDepartmentService.selectList(pageInfo);
        }else{
            return sysDepartmentService.selectList(id);
        }
    }

 

 

 但是點完treegrid之后，再翻頁，easyui會將id再傳過去，所以我們需要在

 onLoadSuccess:function(data){
                delete $(this).treegrid('options').queryParams['id'];  
},

 

 

 

這樣就可以完成treegrid分頁操作！
