Ext.grid.GridPanel loadMask 没效果 失效 解决办法

Ext.onReady(function(){          var proxy=new Ext.data.HttpProxy({url:'JsonServlet?          action=moneyList'});          var record=new Ext.data.Record.create([{name:'id',type:'string',mapping:'id'},{name:'userName',type:'auto',mapping:'userName'},{name:'idCard',type:'auto',mapping:'idCard'},{name:'docId',tpye:'auto',mapping:'docId'},{name:'date',type:'auto',mapping:'date'},{name:'ymoney',type:'auto',mapping:'ymoney'},{name:'smoney',type:'auto',mapping:'smoney'}]);var reader=new Ext.data.JsonReader({totalProperty:'count',root:'root'},record);var store=new Ext.data.Store({proxy:proxy,reader:reader});                store.load({params:{start:0,limit:300}});//表格列var cm=new Ext.grid.ColumnModel([{header:'薪酬发放单号',dataIndex:'id'},{header:'姓名',dataIndex:'userName'},{header:'身份证号',dataIndex:'idCard'},{header:'档案编号',dataIndex:'docId'},{header:'登记时间',dataIndex:'date'},{header:'应发金额',dataIndex:'ymoney'},{header:'实发金额',dataIndex:'smoney'}]);//表格var grid=new Ext.grid.GridPanel({store:store,cm:cm,autoHeight:true,bodyStyle:"width:100%",autoWidth:true,renderTo:'div1',frame:true,/* *默认情况下，grid可以拖放列，也可以改变列的宽度，如果要禁用这两个功能，可以在定义Grid对象时分别设置enableColumnMove和enableColumnResize为false即可 */enableColumnMove:false,enableColumnResize:false,//grid还支持一种读取数据时的遮罩和提示功能，设置属性loadMask:true，在store.load()完成之前会一直显示"Loading。。。。。。。。。"loadMask:true});});

?如上代码：loadMask：true没有任何效果

解决办法：store.load()这句话需要放在var grid=new Ext.grid.GridPanel({})之后

修改后的代码：

Ext.onReady(function(){var proxy=new Ext.data.HttpProxy({url:'JsonServlet?action=moneyList'});var record=new Ext.data.Record.create([{name:'id',type:'string',mapping:'id'},{name:'userName',type:'auto',mapping:'userName'},{name:'idCard',type:'auto',mapping:'idCard'},{name:'docId',tpye:'auto',mapping:'docId'},{name:'date',type:'auto',mapping:'date'},{name:'ymoney',type:'auto',mapping:'ymoney'},{name:'smoney',type:'auto',mapping:'smoney'}]);var reader=new Ext.data.JsonReader({totalProperty:'count',root:'root'},record);var store=new Ext.data.Store({proxy:proxy,reader:reader});//表格列var cm=new Ext.grid.ColumnModel([{header:'薪酬发放单号',dataIndex:'id'},{header:'姓名',dataIndex:'userName'},{header:'身份证号',dataIndex:'idCard'},{header:'档案编号',dataIndex:'docId'},{header:'登记时间',dataIndex:'date'},{header:'应发金额',dataIndex:'ymoney'},{header:'实发金额',dataIndex:'smoney'}]);//表格var grid=new Ext.grid.GridPanel({store:store,cm:cm,autoHeight:true,bodyStyle:"width:100%",autoWidth:true,renderTo:'div1',frame:true,/* *默认情况下，grid可以拖放列，也可以改变列的宽度，如果要禁用这两个功能，可以在定义Grid对象时分别设置enableColumnMove和enableColumnResize为false即可 */enableColumnMove:false,enableColumnResize:false,//grid还支持一种读取数据时的遮罩和提示功能，设置属性loadMask:true，在store.load()完成之前会一直显示"Loading。。。。。。。。。"loadMask:true});store.load({params:{start:0,limit:300}});});
