This preview link the application of thumb I've ever met before at a premium template created MKR Site. The function of these effects is quite simple: give the appearance of a web page / blog which is applied through the web page links to provide a certain class.
Here's how its application:
Please apply the script below just above the </ body> or </ head>
<script type = 'text / javascript'>
// <! [CDATA [

$ ('# p1 a'). miniPreview ({prefetch: 'pageload'});
$ ('# p2 a'). miniPreview ({prefetch: 'parenthover'});

});
(function ($) {
var PREFIX = 'link-preview';
$ .fn.miniPreview = function (options) {
return this.each (function () {
var $ this = $ (this);
miniPreview var = $ this.data (PREFIX);
if (miniPreview) {
miniPreview.destroy ();
}
miniPreview = new MiniPreview ($ this, options);
miniPreview.generate ();
$ this.data (PREFIX, miniPreview);
});
};
var MiniPreview = function ($ el, options) {
this. $ el = $ el;
this.options = $ .extend ({}, this.defaultOptions, options);
this.counter = MiniPreview.prototype.sharedCounter ++;
