Answer 2

这个麻烦点的 <script language="javascript">
        Ext.onReady(
        function()
        {
            var store = new Ext.data.ArrayStore({
                fields: ['name', 'id'],
                data: [["张三", 1], ["李四", 2]] // from states.js
            });
            var cb = new Ext.form.ComboBox(
            {
                name: "mycombox",
                store: store,
                displayField: "name",
                valueFiled: "id",
                mode: 'local',
                triggerAction: "all",
                renderTo: Ext.getBody()
                
            });
            //下拉框展开时让其关闭
            function x() { this.collapse(); }            var btn = new Ext.Button(
            {
                text: "禁用combox下拉",
                renderTo: Ext.getBody(),
                listeners: { "click": function()
                {
                    cb.addListener("expand",x , cb);//处理展开事件
                }
                }            }
            );
            var btn1 = new Ext.Button(
            {
                text: "启用combox下拉",
                renderTo: Ext.getBody(),
                listeners: { "click": function()
                {
                    cb.removeListener("expand", x, cb);
                }
                }            });
        }
        );
    </script>

                                                            store:new Ext.data.SimpleStore({
                                                            fields:["value","text"],
                                                            data:[["0","未知性别"],["1","男性"],["2","女性"]]
                                                                                    }),

                                                                                    {
                                                                                        if(e.getKey()==Ext.EventObject.ENTER)
                                                                                            {
                                                                                                Ext.getCmp('NewMark_Id_Age').focus(true,true);
                                                                                            }
                                                                                    }
                                                                        }
                                                         }]
