store 加载异常处理与加载信息提示

Posted 2020-06-15

1.      var msgTip = ‘‘;   // 一定要定义在使用前，且定义为全局变量  
2. /--------------------------------store---------------------------------------------------------------//  
3. window.panelStore5 = Ext.create(‘Ext.data.Store‘, {  
4.  fields:[{name:‘name‘},{name:‘preStatics‘,type:‘int‘},‘mypercent‘],  
5.     proxy: {  
6.        type: ‘ajax‘,  
7.        url: extPath+‘/center!getDetailByType.action?random=‘+new Date().getTime()+‘‘+‘&type=5‘,  
8.        reader: {  
9.            type: ‘json‘,  
10.            root: ‘humresData‘,  
11.            totalProperty: ‘totalCount‘  
12.         }  
13.   },  
14.     autoLoad: false,  
15.     sorters:[{  
16.         property:"name",  
17.         direction:"asc"  
18.     },{  
19.         property:"preStatics",  
20.         direction:"asc"  
21.       }],  
22.   listeners:{  
23.          beforeload:function(store,records,successful,operation,opts){  
24.                  msgTip = Ext.MessageBox.show({  
25.                   title:‘提示‘,  
26.                   width : 250,  
27.                   msg:‘页面统计信息刷新中,请稍后...‘,  
28.                   buttons: Ext.Msg.OK  
29.                   
30.                  });  
31.              },  
32.         load:function(store,records,successful,operation,opts){  
33.                 if(successful){  
34.                     Ext.Msg.alert(‘提示‘,‘数据加载成功!‘);  
35.                     msgTip.hide();  
36.                       
37.                 }else{  
38.                       
39.                     Ext.Msg.alert(‘提示‘,‘数据加载失败!‘);  
40.                     msgTip.hide();  
41.                 }          
42.            }  
43.   }  
44. });    

1. 服务器 返回数值 类似：{ success:true,humerdata:{name:‘andy‘,password:123123} } //humerdata 为root  

2.store 遍历二种方式

 

  stroe.each(function(rec){

alert(rec.get(‘name‘));//name 为fields 字段

or： alert(rec.data.name)//name 为fields 字段

   })
