其实这是我犯的最低级的错误,我在火狐上运行,firebug没有报错,而后台的数据能正常获取,但是extjs就是不能显示.

<script type="text/javascript"> Ext.onReady(function(){ //创建一个store var store=new Ext.data.Store({ //从服务器端加载 url:"ext/xml/Employee.xml" , reader:new Ext.data.XmlReader({ //是以那个标签为一记录的 record:"employee", id:"empno", totalRecords:"@total" },[ {name:"empno"}, {name:"name"}, {name:"job"}, {name:"birthday",type:"date",dateFormat:"Y-m-d"}, {name:"salary"}, {name:"comm"}, {name:"dname" ,mapping:"dept > dname"}, {name:"loc" ,mapping:"dept > loc"}, {name:"deptno" ,mapping:"dept > deptno"} ]) }); //创建一个grid var grid=new Ext.grid.GridPanel({ store:store, columns:[ {id:"empno",header:"编号",width:120,dataIndex:"empno",sortable:true}, {header:"姓名",width:120,dataIndex:"name",sortable:true}, {header:"工作",width:120,dataIndex:"job",sortable:true}, {header:"生日",width:140,dataIndex:"birthday",sortable:true,renderer:Ext.util.Format.dateRenderer("Y/m/d")}, {header:"工资",width:120,dataIndex:"salary",sortable:true,renderer:Ext.util.Format.usMoney}, {header:"奖金",width:120,dataIndex:"comm",sortable:true,renderer:Ext.util.Format.usMoney}, {header:"部门名称",width:110,dataIndex:"dname",sortable:true}, {header:"位置",width:120,dataIndex:"loc",sortable:true}, {header:"部门编号",width:120,dataIndex:"deptno",sortable:true} ], sm:new Ext.grid.RowSelectionModel({singleSelect:true}), viewConfig:{ forceFit:true }, height:210, split:true, region:"north" }); //定义显示详细信息模版 var bookTplMarkup=[ '部门编号:{deptno}<br/>', '部门名称:{dname}<br/>', '位置:{loc}<br/>' ]; //创建模版 var bookTpl=new Ext.Template(bookTplMarkup); //创建panel var ct=new Ext.Panel({ render:"binding-example", frame:true, title:"Book List", width:540, height:400, layout:"border", items:[ grid, { id:"detailPanel", region:"center", bodyStyle:{ background:"#ffffff", padding:"7px" }, html:"测试的显示的信息" } ] }); grid.getSelectionModel().on("rowselect",function(sm,rowIndex,r){ //得到panel对象 var detailPanel=Ext.getCmp("detailPanel"); bookTpl.overwrite(detailPanel.body,r.data); }); //手动调用加载 store.load({callback:function(){ // alert(Ext.util.JSON.encode(store.getAt(0).data)); }}); }); </script>
注意看代码的这里,我也没想到会犯这么低级错误,所以检查错误的时候需要仔细.

仔细看这里:

之中的renderTo写成了render,火狐是不会报错的.也不显示,
