JQueryLoader

This plugin allows to delay rendering parts of a page that are loaded later on asynchronously and patched into the page.

Usage

Add the %JQREQUIRE{"loader"}% macro to the page that you want to use this module on. Then add the jqLoader css class to the div (or verbatim) element which will serve as a container for the content to be loaded. Any jqLoader container requires either an url or a section parameter to specify the location from where to load the content.

Parameter are specified using JQueryMetadata, as in

<div class="jqLoader {key:'value', ....}"></div>

Parameter	Description	Default
url	the full url from where the content, e.g. url:'http://www.rockbox.org/wiki/MyWeb/MyTopic?section=mysection;skin=text'
section	the ...
mode	specify whether the content is either loaded automatically or by clicking on the container; possible values: auto, manual	auto
placeholder	the image to be displayed as long as the content hasn't been loaded
effect	the effect used when showing the loaded content; possible values are: show, fade, slide, blind, clip, drop, explode, fold, puff, pulsate, highlight	fade
effectspeed	the effect speed in milliseconds used in animated display modes	500
effectopts	additional options for the selected effect; possible values vary depending on the actual effect being used
delay	additional time in miliseconds to delay fetching the content from the content; specifying 0 means load the content immediately; any other value will wait that time until issuing the request	0
onload	a JavaScript function called when the content has been loaded
beforeload	a JavaScript function called before the content is requested
finished	a JavaScript function called when the content has been loaded and displayed on the page

The jqLoader element is able to receive JavaScript events and process them accordingly. Similarly these events can be used to hook your own callbacks to be processed when they are fired.

Event	Description
beforeload.jqLoader	is triggered before requesting the content from the backend (see beforeload parameter above)
finished.jqLoader	is triggered when content has been loaded and finally been displayed on the page (see finished parameter above)
onload.jqLoader	is triggered when the content has been successfully been loaded (see onload parameter above)
refresh.jqLoader	when triggered will reload the content from the backend

Examples

%JQREQUIRE{"loader"}%
<verbatim class="jqLoader {section:'recentchanges', effect:'fade'}" id="myLoader">
%STARTSECTION{"recentchanges"}%<!-- -->
%SEARCH{
    "'1'" 
    web="%BASEWEB%" 
    type="query" 
    nonoise="on" 
    order="modified" 
    reverse="on"
    limit="10"
    format="<p class='foswikiSearchResult'>[[$web.$topic]] $date - $rev - $wikiusername</p>"
}%
<!-- -->%ENDSECTION{"recentchanges"}%
</verbatim>
