Waterfall
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 style="text-align:center;padding:10px 0; color:#999;"><img src="data:image/gif;base64,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" 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; } } }, debug: false });
