// The data store containing the list of states
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
Ext.create('Ext.form.ComboBox', {
fieldLabel: 'Choose State',
store: states,
queryMode: 'local',
displayField: 'name',
valueField: 'abbr',
renderTo: Ext.getBody()
});
//上面是EXTJS的API上面的例子。你如果想要从数据库里面取数据的话,就把store改一下就OK:
var states = Ext.create('Ext.data.Store', {
model: 'User',
proxy: {
type: 'ajax',
url: '/users.json',
reader: {
type: 'json',
root: 'users'
}
},
autoLoad: true
});
