我有 4 个网格表。他们使用相同的模态。我不能使用同一个存储,因为每个网格都必须发送一个参数值才能从 db 获取数据。所以,发生的事情是我最终创建了 4 个不同的商店,然后当我加载我的应用程序时,它滞后了,因为它等待加载所有 4 个商店。这是我的网格..所以我还有 3 个这样的网格
this.grid1 =Ext.create('Ext.grid.Panel',{
title:'GridView App', store: store, loadMask:true,
columns:[
{ header:'Q1', sortable:true, dataIndex:'Q1', flex:1,},
{ header:'Q2', sortable:true, dataIndex:'Q2', flex:1,},
{ header:'Q3', sortable:true, dataIndex:'Q3', flex:1,},
{ header:'Q4', sortable:true, dataIndex:'Q4', flex:1,}
这是我的 store1 ... 同样,我还有 3 个这样的商店,每个商店的参数分别为 Q2、Q3、Q4
var store1 =Ext.create('Ext.data.JsonStore',{
storeId:'myData', scope:this,
fields:[
{ name:'Q1', type:'int'},
{ name:'Q2', type:'int'},
{ name:'Q3', type:'int'},
{ name:'Q4', type:'int'}
],
sorters:[{ property:'Q1', direct:'ASC'}],
proxy:{
type:'ajax',
url:'GridView/writeRecord',
extraParams: { ID: Q1 },
reader: newExt.data.JsonReader({
root:'myTable',
totalProperty:'count'
})
}
});
有没有比我现有的方式更快/更好的方式来实现它?
更新 -
第二次更新 -
这是整个应用程序的布局...我的 rightcontainer 最初被禁用并包含实际的网格和表单,然后单击选项卡上的项目启用 rightcontainer 并加载所有网格。
