- 我的ext php后台怎么不显示数据，我用firebug能看到数据,望各位能帮帮忙。
a.php显示
<html><link rel="stylesheet" type="text/css" href="/ad/publisher/js/ext2/resources/css/ext-all.css" /><script type="text/javascript" src="/ad/publisher/js/ext2/adapter/ext/ext-base.js"></script><script type="text/javascript" src="/ad/publisher/js/ext2/ext-all.js"></script><script type="text/javascript" src="/ad/publisher/js/ext2/examples/examples.js"></script><link rel="stylesheet" type="text/css" href="/ad/publisher/js/ext2/examples/grid/grid-examples.css" /><script>Ext.onReady(function(){ var sm = new Ext.grid.CheckboxSelectionModel(); var cm = new Ext.grid.ColumnModel([ new Ext.grid.RowNumberer(), sm, {header:"编号",dataIndex:"id"}, {header:"名称",dataIndex:"name"}, {header:"描述",dataIndex:"descn"} ]); cm.defaultSortable = true; var ds = new Ext.data.Store({ proxy: new Ext.data.HttpProxy({url:"/ad/admin/module/admanage/hotspot/date.php"}),reader: new Ext.data.JsonReader({ totalProperty: "totalProperty", root: "root" }, [ {name: "id"}, {name: "name"}, {name: "descn"} ]) }); var grid = new Ext.grid.GridPanel({ el: "grid3", ds: ds, cm: cm, sm: sm, title: "ASP->JSON", bbar: new Ext.PagingToolbar({ pageSize: 10, store: ds, displayInfo: true, displayMsg: "显示第 {0} 条到 {1} 条记录，一共 {2} 条", emptyMsg: "没有记录" }), tbar: new Ext.PagingToolbar({ pageSize: 10, store: ds, displayInfo: true, displayMsg: "显示第 {0} 条到 {1} 条记录，一共 {2} 条", emptyMsg: "没有记录" }), height:500, width:860 //autoHeight: true//一定要写，否则显示的数据会少一行 }); ds.load({params:{start:0,limit:10}}); grid.render();});</script><div id="grid3"></div></html> data.php
<?$start= $vars["start"];$limit = $vars["limit"]; $db = new ps_DB; $db->connect(); $hot = new Hot(null,$db); $rs = $hot->LoadList($start,$limit); $db->close(); $cu = 200; $cou = count($rs);?>{totalProperty:<?=$cu?>,root:[<? foreach($rs as $num=>$obj) { $name = iconv("gb2312", "UTF-8", $obj->name);?>{'id':'<?=$obj->id?>','name':'<?=$name?>','descn':descn'<?=$obj->id?>'}<? if($num+1 != $cou) { ?>,<? } } ?>]} 页面/data.php?limit=10&start=0
显示结果为：
{totalProperty:200,root:[{'id':'224','name':'224','descn':descn'224'},{'id':'10','name':'10','descn':descn'10'},{'id':'55','name':'55','descn':descn'55'},{'id':'90','name':'90','descn':descn'90'},{'id':'112','name':'112','descn':descn'112'},{'id':'206','name':'206','descn':descn'206'},{'id':'207','name':'207','descn':descn'207'},{'id':'208','name':'208','descn':descn'208'},{'id':'209','name':'209','descn':descn'209'},{'id':'210','name':'210','descn':descn'210'}]} 请问各位为什么在friebug中能显示json的值，而在a.php中数据老是不显示？
