This option is set up to add a period to the beginning of this option, to make a jQuery class name selector.

This widget will work with the pager and columnSelector widget, so you shouldn't need to trigger this event, but you may need to use it if new rows are added or a cell with an image is updated.

For more details, see the main plugin page.

If you want images to load earlier use threshold parameter. Setting threshold to 200 causes image to load 200 pixels before it appears on viewport.

For more details, see the main documentation.

If you have a funky layout set this number to something high. Worst case being the actual number of images.

For more details, see the main documentation.

In the original plugin, the default for this option is "scroll". It was changed to "scrollstop" in this widget to only load images after scrolling stops.

Alternative settings include "click" (user clicks on image to load it) or "mouseover".

If this option is not set to "scrollstop", then the scrollstop plugin will not be initialized.

For more details, see the main documentation.

You can use any effect you want, e.g. 'fadeIn' effect.

For more details, see the main documentation.

Just pass the container as jQuery object.

Use this option to set a different attribute.

If you have a higher quality image that you want to load under certain conditions, use the lazyload_appear callback to change this setting. Here is an example that switches to load retina images:

$(function() {
	$( 'table' ).tablesorter({
		theme : 'blue',
		widgets : [ 'lazyload' ],
		widgetOptions : {
			lazyload_appear : function( elements_left, settings ) {
				// elements_left = number of images left to load
				// settings = lazyload plugin settings; not the widgetOptions setting which don't matter at this point
				settings.data_attribute = window.devicePixelRatio > 1 && $( this ).attr( 'retina' ) ?
					// use "data-retina" for higher resolution images
					'retina' :
					// fallback to "data-original" for non-retina displays
					'original';
			}
		}
	});
});

For more details, see the main documentation.

To improve performance you can ignore .not(":visible") images by setting this option to true.

For more details, see the main documentation.

Use this callback function as follows:

$(function() {
	$( 'table' ).tablesorter({
		theme : 'blue',
		widgets : [ 'lazyload' ],
		widgetOptions : {
			lazyload_appear : function( elements_left, settings ) {
				// elements_left = number of images left to load
				// settings = plugin settings; not the widgetOptions
				$( this ).parent().addClass( 'loading' );
			}
		}
	});
});

There doesn't appear to be any documentation for this callback in the main documentation.

			}
		}
	});
