Extjs combobox 修改显示问题

Question

我数据库存储的是id，显示的是value. 修改的时候用loadrecord加载显示的就是id了
又没有什么好的办法啊？

Answer 1

将对应的value也设为一个表字段
下面是一个例子：
    var nvccusStore = new Ext.data.Store(
                             {
                                 proxy: new Ext.data.HttpProxy
                               (
                                 { url: "json/teachmana/answerinfo_put.aspx?msg=nvccusNo" }
                               ),
                                 waitMsgTarget: true,
                                 reader: new Ext.data.JsonReader(
                                                                   {
                                                                       root: 'data',
                                                                       fields:
                                                                            [
                                                                             { name: 'nvccusNo', type: 'string' },
                                                                             { name: 'nvccusName', type: 'string' }
                                                                            ]
                                                                   }
                                                             )
                         }
                            );
    nvccusStore.load();    var nvccusNameCmb = new Ext.form.ComboBox
       (
           {
               store: nvccusStore,
               editable: false,
               name: "nvccusNo",
               displayField: "nvccusName",
               valueField: "nvccusName",
               hiddenName: "nvccusNo", //其作用就是让提交时获得的值是valueField所对应的值，否则:将截断字符串或二进制数据
               mode: "local",
               typeAhead: true,
               triggerAction: "all",
               anchor: "95%",
               fieldLabel: "归属课程<span style='color: #FF0000'>*</span>",
               allowBlank: false, //不允许为空
               blankText: '请填写所属课程范围', //错误提示信息
               selectOnFocus: true
           }
       );注意下：
               displayField: "nvccusName",
               valueField: "nvccusName",
可能会解决你的问题！！！
