怎么触发combobox中onChange事件
我使用了easyUI中的combobox控件,需要在combobox值被改变时触发事件,类似普通&select …. onChange="doSomeThing();"/&,但是我无法触发combobox控件的onChange()事件,请问我该怎么才能获得onChange()事件,还有就是如何获得该combobox当前所选定的值,谢谢!我的代码如下:

Re: 怎么触发combobox中onChange事件
$('#cc').combobox({
onChange:function(newValue,oldValue){
alert(newValue);
To get the field value, you could invoke the 'getValue' method. The code looks like this:
$('#cc').combobox('getValue');

It was quite effective,thank you very much!
easyui form components such as datebox, validationbox, combobox cannot display in correct position when style is absolut
Recently, after few weeks studying in easyui. I found it was a good web ui presentation framework.
But I met a problem during the test period. The below code which is problem I met. The easyui form component cannot present in correct absolution position.
&!DOCTYPE html PUBLIC &-//W3C//DTD HTML 4.01 Transitional//EN& &http://www.w3.org/TR/html4/loose.dtd&&
&meta http-equiv=&Content-Type& content=&text/ charset=UTF-8&&
&title&DateBox - jQuery EasyUI Demo&/title&
&link rel=&stylesheet& type=&text/css& href=&../themes/default/easyui.css&&
&link rel=&stylesheet& type=&text/css& href=&../themes/icon.css&&
&link rel=&stylesheet& type=&text/css& href=&demo.css&&
&script type=&text/javascript& src=&../jquery-1.6.min.js&&&/script&
&script type=&text/javascript& src=&../jquery.easyui.min.js&&&/script&
&script type=&text/javascript& src=&../locale/easyui-lang-zh_TW.js&&&/script&
&h2&DateBox&/h2&
&input id=&dd& class=&easyui-datebox& required=&true& style='position:top:100left:100px'&&/input&
I am looking forward to hear from you soon and help us to solve this issue. This will help us to decide to select easyui as our front-end framework in our business application. and we will are glad to buy the commerical license if we confirmed this framework is suitable for our upgrade requirement.
Best Regards,

Re: easyui form components such as datebox, validationbox, combobox cannot display in correct position when style is absolut
The datebox is an inline component, so the 'position:absolute' style is not valid.
To solve this issue, wrap a block element for it:
&div style=&position:top:100left:100px&&
&input id=&dd& class=&easyui-datebox& required=&true&&&/input&

Thanks! We will try it.

Combobox.SelectedIndex = 0 //是SelectIndex还是SelectedIndex有点忘记了，反正你看下就知道了。
如果是数据是从数据库中取的，那么SQL语句就写成“select distinct 列名 from 表名”
Enabled = False应该可以吧

相关问答：123456789101112131415extjs combobox 如何获取点击事件
- ITeye问答
extjs combobox 我想获取点击输入框旁边那个按钮的事件，expand事件满足不了我的需求。求指教&
你的需求到底是什么？
change---显示的值改变事件
select---选中选项事件
expand---下拉框展开事件
collapse--下拉框折叠事件
基本能满足需要了吧
var combo = new boBox({
store: store,
displayField:'state',
typeAhead: true,
mode: 'local',
forceSelection: true,
triggerAction: 'all',
emptyText:'Select a state...',
selectOnFocus:true,
applyTo: 'local-states',
onTriggerClick:function(){
alert('abc');
ComboBox没的click事件，下拉按钮的点击事件处理是通过重载从Ext.form.TriggerFiled中继承的方法onTriggerClick实现，如上我给的实现，但是这种实现破坏了combobox原有的功能。
要不你描述下有何有需求，怎么可能expand事件满足不了呢
是那个用户在点击下拉箭头，onTriggerClick 这个吧。

博客分类：
因为项目需要，想用Ext的combo控件实现动态级联，发现combo确实不好用，也可能是我对这个组建不熟悉吧，拿动态级联来讲，首先我们能想到的触发事件肯定就是change事件了，可不幸的是，这个change时间并不像我们原生的HTML中的 select的onchange事件，这个change事件需要使当前控件失去焦点、或者在空白处点击下才能达到和select中onchange一样的效果，我有点想不明白，Ext开发小组难道有意这么做吗？还是这是个BUG，在我看来这个change事件有和没有区别不大，所以我这里只能用select时间代替change事件了。
'select' : function(combo, rex, index ){
alert(index);
