ExtJs中ComboBox使用之技巧

在ExtJs中，想要提交ComboBox的Value，需要设置hiddenName:

 1 xtype: 'combo',
 2                                        fieldLabel: '产品品牌',
 3                                        emptyText: "--产品品牌--",
 4                                        displayField: 'Name',
 5                                        valueField: 'Id',
 6                                        hiddenName:'brand',
 7                                        triggerAction: 'all',
 8                                         120,
 9                                        editable: false,
10                                        forceSelection: true,
11                                        allowBlank: false,
12                                        store: new Ext.data.JsonStore({
13                                            url: '/admin/getproductbrands',
14                                            root: 'ProductBrands',
15                                            fields: ['Id', 'Name']
16                                        })
