According to the requirements to achieve by moving up and down the keyboard, the value in the lenovo menu, just like Google baidu query function. Looking for a long time on the Internet did not find the plug-in can achieve this function, but had to change their own code. Find keydown and keyup in js to execute the code As follows:

case KEY.DOWN:
event.preventDefault();
if ( select.visible() ) {
select.next();
}
else {
onChange(0, true);
}
break;

In the select next (); After joining

var selected = select.selected();
var v = selected.result;
$input.val(v);

After such addition, when the up and down keys input box will have the corresponding value, but the lenovo keyboard cursor is missing. Find the select next (); Definition of code

next: function() {
moveSelect(1);
},

Add a similar method

stay: function() {
moveSelect(1);
},

then

case KEY.DOWN:
event.preventDefault();
if ( select.visible() ) {
select.next();
var selected = select.selected();
var v = selected.result;
$input.val(v);
select.stay();
}
else {
onChange(0, true);
}
break;

That’s it.

= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =

Thank you very much,

Add a similar method

stay: function() {
moveSelect(1);
}, After clicking the up and down key, I found that it was interlacing, so I changed it to:

stay: function() {
moveSelect(0);
},
