Question

As described in title I need to display qtip tooltip when click on input field and if there is more than 2 chars typed then hide qtip

Answer 1

In order to show/hide the qTip based on the length of the input, use this:

$('#textbox').qtip();

$("#textbox")
    .bind("focus keyup change", function () {
        $(this).qtip('toggle', ($(this).val().length <= 2));
});
