I have text input, and when I focusing on it - first '.option' of '#number_list' become '.selected'. I want to create a feature - when Up or Down key on keybord pressed than next or prev element of 'number_list' granding 'selected' class and current element loosing this class.
<input type="text" name="number" id="number" maxlength="30" />
<div id="number_list">
<div class='option selected'>aaa</div>
<div class='option'>bbb</div>
<div class='option'>ccc</div>
</div>
I was trying to create array of '.option' elements and get current element by index, but I don't find any way to do this. So how can it be done? Also I'm using jQuery 1.5.1.
How about this quick-and-dirty implementation: http://jsfiddle.net/zerkms/YNyEr/2/
var $input = $('#some_number'),
current_index = $('.selected').index(),
$number_list = $('#number_list'),
$options = $number_list.find('.option'),
items_total = $options.length;
$input.val(current_index);
$input.bind('keyup', function(e) {
if (e.keyCode == 40) {
if (current_index + 1 < items_total) {
current_index++;
change_selection();
}
} else if (e.keyCode == 38) {
if (current_index > 0) {
current_index--;
change_selection();
}
}
});
function change_selection()
{
$options.removeClass('selected');
$options.eq(current_index).addClass('selected');
$input.val(current_index);
}
I think you should have a look at the javascript events onkeyup and onkeydown. If you play with the selection by id it should be quite easy,
For instance
<div onkeydown='document.getElementById("nextid").className += "selected";this.className -= "selected";' class='option'>bbb</div>
