问题所在:因为之前是将data添加到Proxy中了,所以一直出不来结果。

实现代码:
// The data store containing the list of statesv var states = Ext.create('Ext.data.Store', { fields: ['abbr', 'name'], data : [ {"abbr":"AL", "name":"Alabama"}, {"abbr":"AK", "name":"Alaska"}, {"abbr":"AZ", "name":"Arizona"} //... ] } }); / // Create the combo box, attached to the states data store E Ext.create('Ext.form.ComboBox', { fieldLabel: 'Choose State', store: states, queryMode: 'local', displayField: 'name', valueField: 'abbr', value:'AZ', renderTo: Ext.getBody() } });
