我按照 如何将空项目添加到 ExtJS 组合框?我可以根据需要看到一个空白行/项目,但我无法从组合框中选择任何项目!
有什么猜测吗?
我的代码如下
var rModel = Ext.regModel('State', {
fields: [
{type: 'string', name: 'fips_state_code'},
{type: 'string', name: 'state_name'}
]
});
// The data store holding the states
var store = Ext.create('Ext.data.Store', {
model: 'State',
data: [{fips_state_code: '0', state_name: ' '}]
});
store.add(obj.results);
{
xtype:'combo',
id:'filterstate',
width: 250,
fieldLabel: 'Filter By State',
store: store,
queryMode: 'local',
displayField: 'state_name',
valueField: 'fips_state_code',
editable: false,
forceSelection : true,
triggerAction : 'all',
typeAhead: true,
selectOnFocus:true,
allowBlank:true,
tpl : '<tpl for=\".\"><div class=\"x-combo-list-item\">{state_name} <\/div><\/tpl>'
}
