waterfall

这是瀑布流布局插件, 类似于 Pinterest、花瓣、发现啦。

使用

html：

<div id="container"></div>

引入jquery，handlebars和waterfall(注：waterfall默认返回json格式数据并使用handlebars模板渲染json数据，你也可以在options中配置使用其它javascript模板如mustache解析json数据或者直接返回html):

<script src="/path/jquery.min.js"></script>
<script src="/path/handlebars.js"></script>
<script src="/path/waterfall.min.js"></script>

template:

<script id="waterfall-tpl" type="text/x-handlebars-template">
    //template content
</script>

script:

$('#container').waterfall({
	itemCls: 'waterfall-item', 
	prefix: 'waterfall',
	fitWidth: true, 
	colWidth: 240, 
	gutterWidth: 10,
	gutterHeight: 10,
	align: 'center',
	minCol: 1, 
	maxCol: undefined, 
	maxPage: undefined, 
	bufferPixel: -50, 
	containerStyle: {
		position: 'relative'
	},
	resizable: true, 
	isFadeIn: false,
	isAnimated: false,
	animationOptions: { 
	},
	isAutoPrefill: true,
	checkImagesLoaded: true,
	path: undefined,
	dataType: 'json', 
	params: {}, 
	
	loadingMsg: '<div><img src="data:image/gif;base64" alt=""><br />Loading...</div>',
	
	state: { 
		isDuringAjax: false, 
		isProcessingData: false, 
		isResizing: false,
		curPage: 1 
	},

	// callbacks
	callbacks: {
		/*
		 * loadingStart
		 * @param {Object} loading $('#waterfall-loading')
		 */
		loadingStart: function($loading) {
			$loading.show();
			//console.log('loading', 'start');
		},
		
		/*
		 * loadingFinished
		 * @param {Object} loading $('#waterfall-loading')
		 * @param {Boolean} isBeyondMaxPage
		 */
		loadingFinished: function($loading, isBeyondMaxPage) {
			if ( !isBeyondMaxPage ) {
				$loading.fadeOut();
				//console.log('loading finished');
			} else {
				//console.log('loading isBeyondMaxPage');
				$loading.remove();
			}
		},
		
		/*
		 * loadingError
		 * @param {String} xhr , "end" "error"
		 */
		loadingError: function($message, xhr) {
			$message.html('Data load faild, please try again later.');
		},
		
		/*
		 * renderData
		 * @param {String} data
		 * @param {String} dataType , "json", "jsonp", "html"
		 */
		renderData: function (data, dataType) {
			var tpl,
				template;
				
			if ( dataType === 'json' ||  dataType === 'jsonp'  ) { // json or jsonp format
				tpl = $('#waterfall-tpl').html();
				template = Handlebars.compile(tpl);
				
				return template(data);
			} else { // html format
				return data;
			}
		}
