Extjs Grid 不显示数据
不显示数据（后台已接受请求，并且回发数据），不提示任何错误
确定数据格式以及路径正确
JS如下
var grid;var record;var store;Ext.onReady(function () { //后台返回的数据格式是 {total:总页数值,rows:[{},{}]} store = new Ext.data.JsonStore({ url: 'ExtDataModifyShipAddressList.aspx?p=' + Math.random(), root: 'rows', totalProperty: 'total', fields: [ { name: 'Id' }, { name: 'Sid' }, { name: 'Status' }, { name: 'CustomerID' }, { name: 'Description' }, { name: 'ShipAddress' }, { name: 'StateName' }, { name: 'CityName' }, { name: 'ZipCode' }, { name: 'ContactPerson' }, { name: 'ContactTel' }, { name: 'ShipVia' }, { name: 'Country' }, { name: 'StId' }, { name: 'Default'}], method: 'post' }); //加载数据 store.load({ params: { start: 0, limit: 20 } }); grid = new Ext.grid.GridPanel({ frame: true, title: 'New Customer Application List', stripeRows: true, //斑马线 store: store, applyTo: 'grid', //指定显示数据的div trackMouseOver: true, height: 550, width: window.screen.width - 17, //屏幕分辨率的宽 loadMask: { msg: 'loading……' }, columns: [ new Ext.grid.RowNumberer(), //行号 {header: '<font size=2>Id</font>', dataIndex: 'Id', sortable: true }, { header: '<font size=2>Sid</font>', dataIndex: 'Sid', sortable: true }, { header: '<font size=2>Status</font>', dataIndex: 'Status', sortable: true }, { header: '<font size=2>CustomerID</font>', dataIndex: 'CustomerID', sortable: true }, { header: '<font size=2>Description</font>', dataIndex: 'Description', sortable: true }, { header: '<font size=2>ShipAddress</font>', dataIndex: 'ShipAddress', sortable: true }, { header: '<font size=2>StateName</font>', dataIndex: 'StateName', sortable: true }, { header: '<font size=2>CityName</font>', dataIndex: 'CityName', sortable: true }, { header: '<font size=2>ZipCode</font>', dataIndex: 'ZipCode', sortable: true }, { header: '<font size=2>ContactPerson</font>', dataIndex: 'ContactPerson', sortable: true }, { header: '<font size=2>ContactTel</font>', dataIndex: 'ContactTel', sortable: true }, { header: '<font size=2>ShipVia</font>', dataIndex: 'ShipVia', sortable: true }, { header: '<font size=2>Country</font>', dataIndex: 'Country', sortable: true }, { header: '<font size=2>StId</font>', dataIndex: 'StId', sortable: true}], //分页 bbar: new Ext.PagingToolbar({ pageSize: 20, store: store, displayInfo: true, //显示分页 emptyMsg: "NO DATA" }) }) //底下容器 var bookTplMarkup = [ 'Id: <br/>{Id}<br/><br/>', "<input type='button' value='Del' onclick=Del({Id})><br/>" ]; var bookTpl = new Ext.Template(bookTplMarkup); var ct = new Ext.Panel({ renderTo: 'grid', frame: true, title: 'Customer Detailed Info', loadMask: { msg: 'loading……' }, width: window.screen.width - 17, height: 500, layout: 'border', items: [ grid, { id: 'detailPanel', region: 'center', bodyStyle: { background: '#ffffff', padding: '7px' }, html: 'Please select a row to see additional details.' } ] }) grid.getSelectionModel().on('rowselect', function (sm, rowIdx, r) { var detailPanel = Ext.getCmp('detailPanel'); bookTpl.overwrite(detailPanel.body, r.data); record = r; });})
