Select items in a list with keyup JavaScript, JQuery












-1















I'm trying to make a list to select items but the behavior when I use up or down arrow is not so good. When I use up or down arrows it scrolls the <div> and also select and focus on <li> tag but the scrolls moves first so it seems to be kind of rare.



How can I achieve the correct behavior using up and down key?

  • I really apreciate your help Maciej Wojtasik, no, what I mean just look the behavior of the scroll bar when you type up or down, look this site kwfinder.com and try to chose a language, just move the up an down key arrows and see how the scroll bar moves, and se my example and your example, thats the problem and I do not know how to achieve this.

          $("ul > li").eq(elementIndex).css('color', 'red');

          console.log("Last focused element index: " + elementIndex + " has change to: " + Math.floor(elementIndex + 1));

          $("ul > li").eq(elementIndex + 1).focus();

        }
