Options & Events

This configurable demo is to quickly explore Justified Gallery settings. Moreover, it is also a good example that uses Justified Gallery as a stateful entity. In fact, in this example, Justified Gallery is called when the page is loaded using some settings, and then it is called again only to change a specific setting, leaving the old ones unchanged.

Options

option default value description
rowHeight 120 The preferred rows height in pixel.
maxRowHeight false This option could be a false or negative value to keep it disabled. Could be a number (e.g 200) which specifies the maximum row height in pixel. Alternatively, a string which specifies a percentage (e.g. "200%" means that the row height can't exceed 2 * rowHeight). Note that with this option can crop the images if they need to be higher to be justified.
maxRowsCount 0 This parameter limits the number of rows to show. Justified Gallery hides the unwanted rows, and if the page is resized more (or less) images are shown. Note that this this option doesn't limit the number of rows by making images smaller. A value 0 means disabled.
sizeRangeSuffixes { }

Describes the suffix for each size range. By default other thumbnails are not searched.

To agree with the Flickr's suffixes you should change it in the following way:

{'lt100':'_t',
'lt240':'_m',
'lt320':'_n',
'lt500':'',
'lt640':'_z',
'lt1024':'_b'}

The keys could be specified also as numbers (e.g. {512:'_small', 1024:'_big'} to specify the '_small' suffix for images that are less than 512px on the longest side, and '_big' for bigger ones).

thumbnailPath undefined

To configure a custom thumbnail selector rather than using sizeRangeSuffixes, to have more flexibility in some particular situations. The function will be called giving the following arguments: the current path of the image, the width and the height of the image to show (after it has been resized), and the image element which can be used to get further information.

For example, to select the correct thumbnail changing only a suffix of the current filename (similarly to sizeRangeSuffixes) 

$("#myGallery").justifiedGallery({
  thumbnailPath: function (currentPath, width, height, image) {
    if (Math.max(width, height) < 250) {
      return currentPath.replace(/(.*)(_[a-z]+)(\..*)/, "$1_small$2");
    } else { 
      return currentPath.replace(/(.*)(_[a-z]+)(\..*)/, "$1_medium$2");
    }
  }
});

Remember that if this option is defined, sizeRangeSuffixes is not considered.

lastRow 'nojustify' Decide to justify the last row (using 'justify') or not (using 'nojustify'), or to hide the row if it can't be justified (using 'hide'). By default, using 'nojustify', the last row images are aligned to the left, but they can be also aligned to the center (using 'center') or to the right (using 'right').
captions true Decide if you want to show the captions that appears when your mouse is over the image.
margins 1 Decide the margins between the images
border -1 Decide the border size of the gallery. With a negative value the border will be the same as the margins.
waitThumbnailsLoad true In presence of width and height attributes in thumbnails, the layout is immediately built, and the thumbnails will appear randomly while they are loaded.
randomize false Automatically randomize or not the order of photos.
filter false Can be:
  • false: for a disabled filter.
  • a string: an entry is kept if entry.is(filter string) returns true (see jQuery's .is() function for further information).
  • a function: invoked with arguments (entry, index, array). Return true to keep the entry, false otherwise. see Array.prototype.filter for further information.
sort false Can be
  • false to do not sort.
  • a function to sort them using the function as comparator (see Array.prototype.sort()).
rtl false Right to left mode.
selector 'a, div:not(.spinner)' Used to determines which are the entries of the gallery. Note that, for performance reasons, the entries of the gallery are always direct children of the gallery.
imgSelector '> img, > a > img' Used to determines, given a gallery entry, how to retrieve the thumbnail.
extension /.[^.]+$/ Specify the extension for the images with a regex. Is used to reconstruct the filename of the images, change it if you need. For example /.jpg$/ is to detect only the ".jpg" extension and no more.
refreshTime 250 The waited time before checking the page size. If the page width has changed the gallery layout is rebuilt.
refreshSensitivity 0 Change in width allowed (in px) without re-building the gallery.
rel To rewrite all the links rel attribute with the specified value. For example can be 'gallery1', and is usually used to create gallery group for the lightbox (e.g. Colorbox).
target To rewrite all the links target attribute with the specified value. For example, if you don't use a lightbox, specifying '_blank', all the images will be opened to another page.
justifyThreshold 0.75 If 'available space' / 'row width' > 0.75 the last row is justified, even though the lastRow setting is 'nojustify'.
cssAnimation true Use or not css animations. With CSS animations it's easier to change them by overriding the rules defined by Justified Gallery.
imagesAnimationDuration 500 Image fadeIn duration (in milliseconds). This is ignored if CSS animations are used.
captionSettings { animationDuration: 500,
  visibleOpacity: 0.7,
  nonVisibleOpacity: 0.0 } 		Caption settings. To configure the animation duration (in milliseconds), the caption opacity when the mouse is over (i.e. it should be visible), and the caption opacity when the mouse is not over (i.e. it should be not visible). This is ignored if CSS animations are used.

Commands

Command Description
norewind Call again justified gallery, but only the newest images will be justified. This command could be used for example with the infinite scroll. Remember that with norewind only the last images will be analyzed, so this means that any pre-defined filter, sort, or shuffle actions will only be done on the last entries. That is a great advantage in terms of performances, but pay attention in case you want a different behaviour.
destroy Destroy the justified gallery instance. The images justification will be cleared.

Example

$('#commandtest').justifiedGallery('norewind');

Events

Event Description
jg.complete When the algorithm finished to create the gallery layout.
jg.resize When the algorithm finished to resize the gallery.
jg.rowflush When the a new row is ready.

Example

$('#callbacktest').justifiedGallery().on('jg.complete', function (e) {
    alert('on complete');
});
