所选单选上的按键事件
问题描述：
我想在选择的jquery单选上按下回车键时自动添加选择的值.那么，是否存在像按键之类的事件，当按下回车键时，我会用它来做某事?
I would like to automatically add the selected value when enter key is pressed on chosen jquery single select. So, for that is there any event like keypress which I would use to do something when return key was pressed?
<select id="myselect" data-placeholder="Add foods you can buy here."
style="height:30px; width: 100%" class="chosen-select" onkeypress="handle(event)" >
<option value=""></option>
<optgroup label="blah">
<option>blah blah</option>
</optgroup>
</select>
答
在初始化后将keyup事件绑定到选定的jquery下拉列表上.
Bind the keyup event on the jquery chosen dropdown, after chosen in initialized.
根据版本，您需要使用.chosen-container或.chzn-container.
Depending upon the version either you need to use .chosen-container or .chzn-container.
$(".chosen-select").chosen({});
$(".chosen-container").bind('keyup',function(e) {
if(e.which === 13) {
$('#myform').submit();
// or your stuff here...
}
});
