Simplest plugin call:

jQuery('#content').ajaxify();
Ajaxifies the whole site, dynamically replacing the div with the ID '#content' across pages

If several divs should be swapped, just specify their IDs like this:
jQuery('#content, #nav').ajaxify();

The plugin can take an arbitrary amount of IDs, however the first one should specify the main content div


Options default values

}

Animation parameters (aniParams):  Default is false (set off)
{
    opacity: 1, //no fade, set to 0 for maximum fade
    width: "100%", //in percent -  "100%" means no change
    height: "100%" //in percent -  "100%" means no change
}

More animation parameters

You can specify any parameters that are understood by .animate() respectively…
