ext中store读值的问题

[Mathilna]

store声明：
var jtbcs=new Ext.data.JsonStore({
autoLoad:true,
proxy:new Ext.data.HttpProxy({
method:'GET',
url:'Action/JKDA/grjkda_jktjb.aspx?type=listJtbcs'
}),
reader:new Ext.data.JsonReader({
root:'rows',
totalProperty:'totalCount',
fields: [
{name: 'JCRQ1',mapping:'JCRQ1',type:'date'},//建床日期
{name: 'CCRQ1',mapping:'CCRQ1',type:'date'},//撤床日期
{name: 'YY',mapping:'YY'},//原因
{name: 'YLJGMC',mapping:'YLJGMC'},//医疗机构名称
{name: 'BAH',mapping:'BAH'}//病案号
]
})
});
grid的声明：
var jtbcsgrid = new Ext.grid.EditorGridPanel({
autoEncode:true,
store:jtbcs,
frame:true,
width:600,
height:200,
anchor:'93%',
clicksToEdit:1,
columns: [
{header: "建床日期", width: 100, sortable: true, dataIndex:"JCRQ1",renderer:dateRender, editor:new Ext.grid.GridEditor(new Ext.form.DateField({format:'Y-m-d',allowBlank:true}))},
{header: "撤床日期", width: 100, sortable: true,dataIndex:"CCRQ1",renderer:dateRender,editor:new Ext.grid.GridEditor(new Ext.form.DateField({format:'Y-m-d',allowBlank:true}))},
{header: "原因", width: 150, sortable: true,dataIndex:"YY",editor:new Ext.grid.GridEditor(new Ext.form.TextField({allowBlank:true}))},
{header: "医疗机构", width: 150, sortable: true,dataIndex:"YLJGMC",editor:new Ext.grid.GridEditor(new Ext.form.TextField({allowBlank:true}))},
{header: "病案号", width: 100, sortable: true,dataIndex:"BAH",editor:new Ext.grid.GridEditor(new Ext.form.TextField({allowBlank:true}))}
],
store:jtbcs,
stripeRows: true
});
重载store：
jtbcs.reload({callback:function(){alert(this.getTotalCount())}}); 返回值为0
而事实上，后台已经把值打印出来了，打印的内容为：
{totalCount:2,rows:[{"JCRQ1":"2010-06-16","YLJGMC":"5","JCRQ":"2010-6-16 0:00:00","CCRQ1":"2010-06-12","JTBCS_ID":"52","GRJKDABH":"奥斯丁发生点","CCRQ":"2010-6-12 0:00:00","YY":"4","BAH":"6"},{"JCRQ1":"2010-06-08","YLJGMC":"2","JCRQ":"2010-6-8 0:00:00","CCRQ1":"2010-06-07","JTBCS_ID":"51","GRJKDABH":"奥斯丁发生点","CCRQ":"2010-6-7 0:00:00","YY":"1","BAH":"3"}]}
屏幕上没有显示，请各位高手帮忙看下，有哪一点代码不明确的请提出来。

加上jtbcs.load();
楼主，代码中多了一个store:jtbcs,

[power0227]

你写了2个 store:jtbcs,

[Mathilna]

删除了一个store：jtbcs，没有变化
1楼的，请问jtbcs.load();加在哪。

[mzoy]

在var jtbcs最后加个jtbcs.load();
没有这个数据肯家不显示的

[Mathilna]

回四楼：
没有用，数据读不到jtbcs里面。而且这个store是在点击某个按钮后才能加载的。

[zoujp_xyz]

这种情况通常是返回的格式不对引起的。楼主仔细看看

[zoujp_xyz]

rows:[]
应该是{}吧

[Mathilna]

问题和解决方法由9楼仁兄给出，非常感谢！
也谢谢各位的捧场，谢谢！

var jtbcs=new Ext.data.JsonStore({  
  autoLoad:true,//这里有自动加载，下面就不需要reload了
  proxy:new Ext.data.HttpProxy({
  method:'GET',
  url:'Action/JKDA/grjkda_jktjb.aspx?type=listJtbcs'
  }),
  reader:new Ext.data.JsonReader({
  root:'rows',
  totalProperty:'totalCount',
  fields: [
  {name: 'JCRQ1',mapping:'JCRQ1',type:'date'},//建床日期
  {name: 'CCRQ1',mapping:'CCRQ1',type:'date'},//撤床日期
  {name: 'YY',mapping:'YY'},//原因
  {name: 'YLJGMC',mapping:'YLJGMC'},//医疗机构名称
  {name: 'BAH',mapping:'BAH'}//病案号
  ]
  })
  });  
grid的声明：
var jtbcsgrid = new Ext.grid.EditorGridPanel({
  autoEncode:true,  
  store:jtbcs,
  frame:true,  
  width:600,  
  height:200,  
  anchor:'93%',
  clicksToEdit:1,
  columns: [
  {header: "建床日期", width: 100, sortable: true, dataIndex:"JCRQ1",renderer:dateRender, editor:new Ext.grid.GridEditor(new Ext.form.DateField({format:'Y-m-d',allowBlank:true}))},
  {header: "撤床日期", width: 100, sortable: true,dataIndex:"CCRQ1",renderer:dateRender,editor:new Ext.grid.GridEditor(new Ext.form.DateField({format:'Y-m-d',allowBlank:true}))},
  {header: "原因", width: 150, sortable: true,dataIndex:"YY",editor:new Ext.grid.GridEditor(new Ext.form.TextField({allowBlank:true}))},
  {header: "医疗机构", width: 150, sortable: true,dataIndex:"YLJGMC",editor:new Ext.grid.GridEditor(new Ext.form.TextField({allowBlank:true}))},
  {header: "病案号", width: 100, sortable: true,dataIndex:"BAH",editor:new Ext.grid.GridEditor(new Ext.form.TextField({allowBlank:true}))}
  ],   
  //store:jtbcs,上面有了store，这里不要
  stripeRows: true   
  });
重载store：
jtbcs.reload({callback:function(){alert(this.getTotalCount())}}); 返回值为0

把你的json字符串拿到firebug下运行了，发现有换行符号。这个要去掉，在输出json字符串的时候
不要带ln这种输出。如:println/writeln 应该用print/write

store这样定义！

 var jtbcs=new Ext.data.JsonStore({  
  autoLoad:true,
  proxy:new Ext.data.HttpProxy({
  method:'GET',
  url:'Action/JKDA/grjkda_jktjb.aspx?type=listJtbcs'
  }),
    root:'rows',
  totalProperty:'totalCount',
  fields: [
  {name: 'JCRQ1',mapping:'JCRQ1',type:'date'},//建床日期
  {name: 'CCRQ1',mapping:'CCRQ1',type:'date'},//撤床日期
  {name: 'YY',mapping:'YY'},//原因
  {name: 'YLJGMC',mapping:'YLJGMC'},//医疗机构名称
  {name: 'BAH',mapping:'BAH'}//病案号
  ]
 
  });  

既然用的是JsonStore就不能用jsonReader，jsonStore默认的就是jsonReader！你先试试看，记得我以前也遇到过这问题！
