组合框项目工具提示不显示 [英] Combo box items tool tip not displayed
问题描述
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 declaredata = [
['AL','阿拉巴马'],
['AK','阿拉斯加'],
['AZ'亚利桑那州],
['WV','西维吉尼亚州],
['WI','威斯康星州],
['WY','怀俄明']
]。
var sstore = new Ext.data.SimpleStore({
fields:['abbr','state'],
data:declaredata
});
非常感谢任何指导。
我假设您使用的是这个例子(该页面的第二个)作为起点? tpl
应该参考示例中显示的有效模板(当然,您似乎正在使用abbr而不是nick,如在示例中 - make确保所有数据字段匹配)。您定义的模板未定义任何工具提示标记。例如:
'< tpl for =。>< div ext:qtip ={state} nick}class =x-combo-list-item> {state}< / div>< / tpl>'
如果它仍然不起作用,请确保您在代码之前的某个地方初始化了快速提示单例:
Ext.QuickTips.init();
I have written a combo box populated with items in ExtJs framework. I could not able to get the tooltips when the user hovers over the items.
Below is the code:
$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
});
Any guidance is highly appreciated.
I assume that you are using this example (the second one on that page) as your starting point? tpl
should refer to a valid template like that shown in the sample (of course it looks like you are using "abbr" instead of "nick" as in the sample -- make sure all data fields match). Your template as defined does not define any tooltip markup. E.g.:
'<tpl for="."><div ext:qtip="{state}. {nick}" class="x-combo-list-item">{state}</div></tpl>'
If it's still not working, make sure you initialized the quick tips singleton somewhere before your code:
Ext.QuickTips.init();
