I've been developing a simple tooltip tool (check out the fiddle link below), but I'm encountering some issues with positioning. My goal is to have the tooltip appear centered and above the clicked link, however right now it appears at the top left corner of the mouse click. I've attempted to adjust this position by offsetting it by half of the tooltip's size, but so far without success.
Be sure to take a look at the updates on http://jsfiddle.net/CBf4C/3/
To determine the position of the clicked element (utilize .position()), retrieve the dimensions of the tooltip using .outerWidth() and .outerHeight(), and then perform calculations based on these values.
The provided code snippet is as follows:
$('a[title]').click(function(e) {
//fade the tooltip and display information
$('body').append('<div class="tooltip"><div class="tipBody"></div></div>');
tip = $(this).attr('title');
var tooltip = $('.tooltip'); // store a reference to the tooltip for later use
tooltip.fadeTo(300, 0.9).children('.tipBody').html(tip);
// calculate the position of the tooltip
var el = $(this),
pos = el.position(), // obtain the position of the clicked element
w = el.outerWidth(), // get the width of the clicked element in order to determine its center
newtop = pos.top - tooltip.outerHeight(), // compute the top position of the tooltip
newleft = pos.left + (w / 2) - (tooltip.outerWidth() / 2); // calculate the left position of the tooltip
// set the position
$('.tooltip').css('left', newleft);
$('.tooltip').css('top', newtop);
hideTip = false;
});
