Question

Even though its origin stickmanlabs.com seems to be down, lightwindow remains a popular javascript lightbox for various purpose. Particularly the TYPO3 community seems to like it thanks to an extension that neatly embeds it. However, unfortunately this extension uses an a tag attribute params which actually isn’t an attribute. It’s not valid? How can I fix this?

Answer 1

This might be a hack, but it validates lightwindow as HTML Transitional.
Just use the hardly used rev tag to transport the lightwindow parameters to .js.

e.g.:

<a href="somelink.html" rev="lightwindow_type=external,lightwindow_width=870,
lightwindow_height=650,lightwindow_show_images=2">

Then just edit the javascript file (in TYPO3 it’s located @: typo3conf/ext/wt_lightwindow/files/js/lightwindow.js ) like this:

_setupWindowElements : function(link) {
    this.element = link;
    this.element.title = null ? '' : link.getAttribute('title');
    this.element.author = null ? '' : link.getAttribute('author');
    this.element.caption = null ? '' : link.getAttribute('caption');
    this.element.rel = null ? '' : link.getAttribute('rel');
    this.element.params = null ? '' : link.getAttribute('rev');

(should be around line 550 of the current version). Just cmd+f for params.
