OnLoad'er

Description

This shortcode, onloader, makes it possible to dynamically load extra content onto a page, with a nice spinning
load indicator taking the place of the content until it is loaded.

Usage

Add a shortcode like the following to the content of a post or page.

[onloader href="..." id="..." width="..." height="..." style="..."]

The href attribute is mandatory, the rest are optional.

Attribute descriptions:

  • href: The URL of the the content that should be loaded and displayed (or a string beginning with “demo”).
  • id: Used to differentiate between several otherwise identical shortcodes on a single page. Should be a simple
    text string beginning with a letter.
  • width: The width of the box that will hold the load indicator and the content once it is loaded, expressed as
    CSS, e.g. 200px or 100%. The default value is 100%.
  • height: The height of the box that will hold the load indicator and the content once it is loaded, expressed as
    CSS, e.g. 200px or 100%. The default value is 200px.
  • style: CSS to style the box that holds the content, e.g. text-align: center; color: red.

Example

[onloader href="http://example.com/feed" id="example1" width="80%" height="15em" style="border: 1px solid blue"]

FAQ

I get a JavaScript error, “Access to restricted URI denied”

Because of the browser/JavaScript security model, it is not possible to load content from other sites, only
from the same domain the OnLoad’er script itself is located on.

A proxy service will be added to a later version of the plugin.

How can I test that it works?

Add the shortcode [onloader href="demo"] to a page, and hit preview. You should see the spinning load indicator,
and after a few seconds the message “You are seeing the output of the OnLoad’er demo script. Everything worked!”.

Can I use more than one on a single page

Certainly. If you are loading content from distinct URLs, it should “just work”, otherwise add id attributes
with suitable values to make it possible to tell them apart.
