我在ExtJs框架中编写了一个填充了项目的组合框.当用户将鼠标悬停在项目上时,我无法获得工具提示.

以下是代码:

$formPanel .= " new Ext.form.ComboBox({
                tpl:'<tpl for =\".\"><div ext:qtip=\"{abbr}\" class=\"x-combo-list-item\">{state}</div></tpl>',
id:'type_blackout_weekly',
  store: sstore,
  displayField:'state',
  typeAhead: true,
  mode: 'local',
  triggerAction: 'all',
  emptyText:'Select a state...',
  selectOnFocus:true,
  forceSelection: true,
  width:135
}),";

var statedata = [
  ['AL', 'Alabama'],
  ['AK', 'Alaska'],
  ['AZ', 'Arizona'],
  ['WV', 'West Virginia'],
  ['WI', 'Wisconsin'],
  ['WY', 'Wyoming']
];

var sstore = new Ext.data.SimpleStore({
  fields: ['abbr', 'state'],
  data : statedata 
});

任何指导都非常感谢.
