ExtJs jsonreader的问题
Store无法得到后台返回的数据，直接输入后台地址是可以得到数据的。忙了5天都弄不出来，请大家帮帮忙。
网页aa.html的代码如下
- JScript code
<html><head><meta http-equiv="Content-Type" content="text/html; charset=gb2312"/><title>Ajax + CGI Test</title> <link rel="stylesheet" type="text/css" href="ext/resources/css/ext-all.css"/> <script type="text/javascript" src="ext/adapter/ext/ext-base.js"></script> <script type="text/javascript" src="ext/ext-all.js"></script><script type="text/javascript"> Ext.onReady(function(){ var cum = new Ext.grid.ColumnModel([ {header:'ID',dataIndex:'id'}, {header:'adValue',dataIndex:'adValue'}, {header:'adTime',dataIndex:'adTime'} ]); var store = new Ext.data.Store({ autoLoad:true, fields:['id','adValue','adTime'], proxy:new Ext.data.HttpProxy ({url:'showAll.cgi'}), reader:new Ext.data.JsonReader({totalProperty:'totalProperty',root:'root'},[{name:'id'},{name:'adValue'},{name:'adTime'}]) });//问题是这个Store得不到showAll.cgi返回的数据， var cumgrid = new Ext.grid.GridPanel({ renderTo:'cumGrid', store:store, stripeRows:true, viewConfig:{ forceFit:true }, autoHeight:true, autoWidth:true, cm:cum, bbar:new Ext.PagingToolbar({ pageSize:10, autowidth:true, store:store, displayInfo:true, emptyMsg:'no record' }) }); //store.load(); cumgrid.render();});</script></head> <body> <dev id ="cumGrid"></div></body></html>直接访问showAll.cgi返回的数据是这样的
- JScript code
{totalProperty:20,root:[{id:'1',adValue:'408 ',adTime:'2012-07-23 19:24:01'},{id:'2',adValue:'408 ',adTime:'2012-07-23 19:24:01'},{id:'3',adValue:'408 ',adTime:'2012-07-23 19:24:02'},{id:'4',adValue:'408 ',adTime:'2012-07-23 19:24:02'},{id:'5',adValue:'408 ',adTime:'2012-07-23 19:24:03'},{id:'6',adValue:'407 ',adTime:'2012-07-23 19:24:03'},{id:'7',adValue:'407 ',adTime:'2012-07-23 19:24:04'},{id:'8',adValue:'407 ',adTime:'2012-07-23 19:24:04'},{id:'9',adValue:'408 ',adTime:'2012-07-23 19:24:05'},{id:'10',adValue:'407 ',adTime:'2012-07-23 19:24:05'},{id:'11',adValue:'407 ',adTime:'2012-07-23 19:24:06'},{id:'12',adValue:'407 ',adTime:'2012-07-23 19:24:06'},{id:'13',adValue:'406 ',adTime:'2012-07-23 19:24:07'},{id:'14',adValue:'407 ',adTime:'2012-07-23 19:24:07'},{id:'15',adValue:'406 ',adTime:'2012-07-23 19:24:08'},{id:'16',adValue:'408 ',adTime:'2012-07-23 19:24:08'},{id:'17',adValue:'407 ',adTime:'2012-07-23 19:24:09'},{id:'18',adValue:'408 ',adTime:'2012-07-23 19:24:09'},{id:'19',adValue:'406 ',adTime:'2012-07-23 19:24:10'},{id:'20',adValue:'405 ',adTime:'2012-07-23 19:24:10'}]}[解决办法]
感觉好像你的这行代码 reader:new Ext.data.JsonReader({totalProperty:'totalProperty',root:'root'},[{name:'id'},{name:'adValue'},{name:'adTime'}])不太对，试下改成：
reader:new Ext.data.JsonReader({totalProperty:'totalProperty',root:'root',fields:[{name:'id'},{name:'adValue'},{name:'adTime'}])
另外拜托你贴代码时整理下格式，有些行错乱很难读。。。
