EXTJS 3.0 资料 控件之 combo 用法

EXTJS combo 控件：

1.先定义store

//年款
var comboData_ReleasYear = [
     [‘0‘, ‘2010‘],
     [‘1‘, ‘2011‘],
     [‘2‘, ‘2013‘],
     [‘3‘, ‘2014‘]
];

2.定义combo控件

{
            layout: ‘form‘,
            labelWidth: 50,
            width: 260,
            items: [{
                xtype: ‘combo‘, name: ‘ReleasYear‘, allowBlank: false,
                fieldLabel: ‘年款‘, width: 150,
                store: new Ext.data.SimpleStore({
                    fields: [‘Id‘, ‘Name‘],
                    data: comboData_ReleasYear
                }),
                valueField: "Id",
                displayField: "Name",
                mode: ‘local‘,
                editable: false,
                triggerAction: ‘all‘,
                allowBlank: false,
                autoload: true,
                listeners: {
                    ‘select‘: function (combo, record, index) {
                        var ReleasYear = PKUPanelForm.form.findField(‘ReleasYear‘).getRawValue();
                        if (ItemStorePKU.getCount() == 0) {
                            ItemStorePKU.insert(0, new ItemStorePKU.recordType({ ReleasYear: ReleasYear }));//插入到最后一行
                        } else {
                            for (var i = 0; i < ItemStorePKU.getCount() ; i++) {
                                ItemStorePKU.insert(i, new ItemStorePKU.recordType({ ReleasYear: ReleasYear }));//插入到最后一行
                            }
                        }
                    }
                }
            }
            ]
        }
