Hello,
I am using Bassistance tooltip but I need to simplify the markup. So
instead of using:
helper.parent = $('<div id="' + settings.id + '"><h3></h3><div
class="body"></div><div class="url"></div></div>')
I would like to use:
helper.parent = $('<div id="' + settings.id + '"><span></span></div>')
However, when I did this change everything stopped working.
I think I need to clean some extra code but all my tries didn't solve
the problem ...
Could someone help me out with this?
Here is the plugin original code:
;(function($) {
// the tooltip element
var helper = {},
// the current tooltipped element
current,
// the title of the current element, used for restoring
title,
// timeout id for delayed tooltips
tID,
// IE 5.5 or 6
IE = $.browser.msie &&
/MSIE\s(5\.5|6\.)/.test(navigator.userAgent),
// flag for mouse tracking
track = false;
$.tooltip = {
blocked: false,
defaults: {
delay: 200,
fade: false,
showURL: true,
extraClass: "",
top: 15,
left: 15,
id: "tooltip"
},
block: function() {
$.tooltip.blocked = !$.tooltip.blocked;
}
};
$.fn.extend({
tooltip: function(settings) {
settings = $.extend({}, $.tooltip.defaults, settings);
createHelper(settings);
return this.each(function() {
$.data(this, "tooltip", settings);
this.tOpacity =
helper.parent.css("opacity");
// copy tooltip into its own expando
and remove the title
this.tooltipText = this.title;
$(this).removeAttr("title");
// also remove alt attribute to prevent
default tooltip in IE
this.alt = "";
})
.mouseover(save)
.mouseout(hide)
.click(hide);
},
