初始化插件
最后通过下面的js代码来初始化该图片画廊插件。
var containerRef = document.getElementById('myGallery'); // uses HTMLElement reference as container
var photoswipeRef = document.getElementById('myPhotoswipe'); // photoswipe template if required
// Create your gallery options
var options = {
format: 'natural | square',
// Max row height. Works for both natural and square format. Prefer this option for a "responsive" approach
rowHeight: 350,
// Only for square format. Disables responsive
imagesPerRow: 4,
round: 3, // Rounded corner
margin: 3, // Gap between thumbnails
limit: 0, // Number of rows, activate pagination (disables infinite scroll)
minRowsAtStart: 2, // Initial number of rows. If null, gallery tries to define the number of required rows to fill the viewport.
showLabels: 'hover | always | never', // When to show the labels in thumbnails
lightbox: true, // Open a lightbox with a bigger image -> activate a zoom effect on hover on thumbnails
zoomRotation: true,
// Number of pixels to offset the infinite scroll autoload
// If negative, next rows will load before the bottom of gallery container is visible
// If 0 the next rows will load when the bottom of the gallery will be visible
// If positive, the next rows will load when the bottom of the gallery will be this amount above the end of the viewport.
// If positive be sure to always have this number of pixels as margin, padding or more content after the gallery.
infiniteScrollOffset: 0,
// Header / Search options.
showCount: false,
searchFilter: false,
categoriesFilter: false,
showNone: false,
