jQuery plugin to call a function when an element appears
Usage
Mimics a custom 'appear' event, which fires when an element scrolls into view or otherwise becomes visible to the user.
$('#foo').appear(function() {
$(this).text('Hello world');
});
This plugin can be used to prevent unnecessary requests for content that's hidden or outside the viewable area.
Usage with additional options
$('#foo').appear(function() {
$(this).text('Hello world');
},{accX: 50, accY: 100});
Will fire 'appear' event with accuracy 50px in X and 100px in Y
