1 1.服务器端代码 2 private <T extends IOrderSupported> String service(IOrderService<T> svc, T form, String error) throws Exception{ 3 SalesOrder var=OrderMngr.get(form.getOrdId()); 4 if(isAuthorized(var)){ 5 svc.service(var, form, request); 6 json=JsonEncodeType.OBJECT.encode(var); 7 return SUCCESS; 8 } 9 return error; 10 }
1 2. js代码 2 //如果客户留言，则添加html代码；如果ppet留言，则不添加html代码 3 function renderLastUpdate(val,x,store){ 4 var r=renderers.lastUpdate(val,x,store); 5 if(store.data.userType=="C"){ 6 r+="<br/><img src='/img/new2_4.gif' title='New remark'/>"; 7 } 8 9 return r; 10 } 11 var columns=[ 12 {header: "流水号",dataIndex: "ordId",hidden:true}, 13 {header: "订单号",dataIndex: "orderNo",renderer:renderCode,sortable:true}, 14 {header: "国家",dataIndex: "nation"}, 15 {header: "客户号",dataIndex: "custId",hidden:true}, 16 {header: "客户",dataIndex: "custCode"}, 17 {header: "客户名称",dataIndex: "custName",hidden:true}, 18 {header: "客户类别",dataIndex: "custCate",hidden:true,renderer:renderCate}, 19 {header: "货币",dataIndex: "currency"}, 20 {header: "汇率",dataIndex: "crRate", renderer: Ext.util.Format.numberRenderer('0,0.00'),hidden:true}, 21 {header: "日期格式",dataIndex: "dateFormat",hidden:true}, 22 {header: "联系人",dataIndex: "linkman"}, 23 {header: "状态",dataIndex: "status", renderer:renderState}, 24 {header: "数量",dataIndex: "qty"}, 25 {header: "净金额",dataIndex: "netAmount", renderer: Ext.util.Format.numberRenderer('0,0.00')}, 26 {header: "附加费用",dataIndex: "additionalCost", renderer: Ext.util.Format.numberRenderer('0,0.00'),hidden:true}, 27 {header: "运费",dataIndex: "deliCost", renderer: Ext.util.Format.numberRenderer('0,0.00'),hidden:true}, 28 {header: "退款订单",dataIndex: "retOrderNo",hidden:true}, 29 {header: "退款额",dataIndex: "retCharge", renderer: Ext.util.Format.numberRenderer('0,0.00'),hidden:true}, 30 {header: "折扣",dataIndex: "discountAmount", renderer: Ext.util.Format.numberRenderer('0,0.00'),hidden:true}, 31 {header: "总金额",dataIndex: "amount", renderer: Ext.util.Format.numberRenderer('0,0.00')}, 32 {header: "备注",dataIndex: "remarks"}, 33 {header: "订单日期",dataIndex: "orderDate", renderer: Ext.util.Format.dateRenderer('Y-m-d')}, 34 {header: "下单者",dataIndex: "issuer"}, 35 {header: "编辑者",dataIndex: "editor",hidden:true}, 36 //{header: "最近更新",dataIndex: "lastUpdate", renderer: Ext.util.Format.dateRenderer('Y-m-d H:i:s'), sortable:true}, 37 {header: "最近更新",dataIndex: "lastUpdate", renderer: renderLastUpdate, sortable:true}, //1.表格面板的列：添加渲染器(函数) 38 {header: "删除",dataIndex: "ordId",hidden:true,renderer:renderers.erase} 39 ];
-----------------
【问题】
1.var实体对象和json对象的userType属性都有值；
2.现在就是，属性的值《——》面板表格的值，这2者怎么关联起来呢？(渲染器函数不是自动执行的么)
补充：
1.
function renderLastUpdate(val,x,store){ //【调试时】当java代码执行完毕，js里设置的断点都没有执行？
var r=renderers.lastUpdate(val,x,store);
if(store.data.userType=="C"){
r+="<br/><img src='/img/new2_4.gif' title='New remark'/>";
}
return r;
}
2.如果只是单独设置js代码里的断点：当刷新后台相应的页面时，下面代码里的判断语句始终是假，也就是说服务器端的json对象的数据没有映射到store.data.userType，如何才能映射呢？
function renderLastUpdate(val,x,store){
var r=renderers.lastUpdate(val,x,store);
if(store.data.userType=="C"){ //1.执行到这一行的时候，判断语句始终为假
r+="<br/><img src='/img/new2_4.gif' title='New remark'/>";
}
return r;
}
