Keypress event on chosen single select
提问by Santosh Ghimire
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?
我想在选定的 jquery 单选上按下 Enter 键时自动添加选定的值。那么，为此有没有像 keypress 这样的事件，当按下返回键时我会用它来做某事？
<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>

Bind the keyupevent on the jquery chosen dropdown, after chosen in initialized.
将keyup事件绑定在jquery 选择的下拉列表上，在选择后初始化。
Depending upon the version either you need to use .chosen-containeror .chzn-container.
根据您需要使用的版本.chosen-container或.chzn-container.
$(".chosen-select").chosen({});
$(".chosen-container").bind('keyup',function(e) {
if(e.which === 13) {
$('#myform').submit();
// or your stuff here...
}
});

I had problema by using the code suggesetd by Mahesh. If so, use keypress instead:
我在使用由Mahesh. 如果是这样，请改用按键：
$(".chosen-container").bind('keypress',function(e) {
if(e.which === 13) {
$('#myform').submit();
// or your stuff here...
}
});
