A jQuery plugin that fades html elements based on their proximity to a source
by Derek Anderson - http://mediaupstream.com
`$('#gallery img').galleryFocus();`
// 'radius' - default: 400 - set the source radius size
// 'fadeTo' - default: 0.2 - the min/max value to fade elements to depending on the value of 'invert'
// 'source' - default: 'cursor' - if set to a class or ID the source will be the center of that DOM element
// 'invert' - default: false - Inverts the direction in which elements fade from the 'source'
// 'overlay' - default: false - displays an overlay to visualize the 'source' influence
$('#gallery img').galleryFocus({
'radius': 800,
'fadeTo': 0.0,
'source': '#source-div',
'invert': true,
'overlay': true
});
- overlay (value)
- update ()
- source (value)
- set (key, value)
- get (key)
Usage is as follows:
toggle overlay on/off
$('#gallery img').galleryFocus('overlay', true);
updates cached positions of all elements, may be required in some cases
$('#gallery img').galleryFocus('update');
set to 'cursor' to bind source to the cursor, or set to a single DOM element eg: '#some-div' or '.a-single-element'
$('#gallery img').galleryFocus('source', 'cursor');
changes the options value
$('#gallery img').galleryFocus('set', 'radius','200');
returns the options value
$('#gallery img').galleryFocus('get','radius');
