photoswipe.min.js 使用

一个类似于手机img展示的js插件

photoswipe的官网 http://photoswipe.com/

首先引入插件里的必须文件

<link rel="stylesheet" type="text/css" href="../public/css/default-skin/default-skin.css"/>
<link rel="stylesheet" type="text/css" href="../public/css/photoswipe.css"/>

<script type="text/javascript" src="../public/js/photoswipe.min.js"></script>
<script type="text/javascript" src="../public/js/photoswipe-ui-default.min.js"></script>

页面布局需要固定格式

<!--data-pswp-uid在每个相册中必须是唯一的，data-size指定放大时图片显示的宽和高-->
<div class="my-gallery clearfix" data-pswp-uid="1">
　    <figure ng-repeat="pic in items.imageDetails" >
        <div class="aixin_pic_con">
            <a href="{{pic.url}}" data-size="670x712">
                <img src="img/diary_list01.fw.png" ng-src="{{pic.url}}">
            </a>
        </div>
        <figcaption style="display:none;" ng-bind="items.crowdTitle">在这里可增加图片描述</figcaption>
      </figure>
</div>

为了在多个页面实现插件的调用使用 便把所有的代码写入一条js里面引入 代码

固定的html代码每个想要调用的页面都需要引入

document.writeln("<!-- Root element of PhotoSwipe. Must have class pswp. -->");
document.writeln("<div class=\"pswp\" tabindex=\"-1\" role=\"dialog\" aria-hidden=\"true\">");
document.writeln("    <!-- Background of PhotoSwipe.");

document.writeln("            <\/div>");
document.writeln("        <\/div>");
document.writeln("    <\/div>");
document.writeln("<\/div>");

固定的js调用方法，每个页面也需要引入

(function() {
 var initPhotoSwipeFromDOM = function(gallerySelector) {
//          console.log(gallerySelector)
            // 解析来自DOM元素幻灯片数据（URL，标题，大小...）
            // (children of gallerySelector)

            var parseThumbnailElements = function(el) {
                        var thumbElements = el.childNodes,

                        for(var i = 0; i < numNodes; i++) { figureEl = thumbElements[i]; // <figure> element // 仅包括元素节点 if(figureEl.nodeType !== 1) { continue; } divEl = figureEl.children[0]; linkEl = divEl.children[0]; // <a> element size = linkEl.getAttribute('data-size').split('x'); // 创建幻灯片对象 item = { src: linkEl.getAttribute('href'), w: parseInt(size[0], 10), h: parseInt(size[1], 10) }; if(figureEl.children.length > 1) { // <figcaption> content item.title = figureEl.children[1].innerHTML;  } if(linkEl.children.length > 0) { // <img> 缩略图节点, 检索缩略图网址 item.msrc = linkEl.children[0].getAttribute('src'); } item.el = figureEl; // 保存链接元素 for getThumbBoundsFn items.push(item); } return items; }; // 查找最近的父节点 var closest = function closest(el, fn) { return el && ( fn(el) ? el : closest(el.parentNode, fn) ); }; // 当用户点击缩略图触发 var onThumbnailsClick = function(e) { e = e || window.event; e.preventDefault ? e.preventDefault() : e.returnValue = false; var eTarget = e.target || e.srcElement; // console.log(eTarget) // find root element of slide 查找幻灯片的根元素 var clickedListItem = closest(eTarget, function(el) { return (el.tagName && el.tagName.toUpperCase() === 'FIGURE'); }); if(!clickedListItem) { return; } // find index of clicked item by looping through all child nodes 通过遍历所有子节点，找到单击项的索引 // alternatively, you may define index via data- attribute 或者，您可以通过data - attribute定义索引 var clickedGallery = clickedListItem.parentNode, childNodes = clickedListItem.parentNode.childNodes, numChildNodes = childNodes.length, nodeIndex = 0, index; // console.log(clickedGallery) for (var i = 0; i < numChildNodes; i++) { if(childNodes[i].nodeType !== 1) { continue;  } if(childNodes[i] === clickedListItem) { index = nodeIndex; break; } nodeIndex++; } if(index >= 0) { // open PhotoSwipe if valid index found openPhotoSwipe( index, clickedGallery ); } return false; }; // parse picture index and gallery index from URL (#&pid=1&gid=2) var photoswipeParseHash = function() { var hash = window.location.hash.substring(1), params = {}; if(hash.length < 5) { return params; } var vars = hash.split('&'); for (var i = 0; i < vars.length; i++) { if(!vars[i]) { continue; } var pair = vars[i].split('=');  if(pair.length < 2) { continue; } params[pair[0]] = pair[1]; } if(params.gid) { params.gid = parseInt(params.gid, 10); } return params; }; var openPhotoSwipe = function(index, galleryElement, disableAnimation, fromURL) { var pswpElement = document.querySelectorAll('.pswp')[0], gallery, options, items; items = parseThumbnailElements(galleryElement); // console.log(galleryElement) // 这里可以定义参数 options = { barsSize: { top: 100, bottom: 100 }, fullscreenEl : false, // shareButtons: [ // {id:'wechat', label:'分享微信', url:'#'}, // {id:'weibo', label:'新浪微博', url:'#'}, // {id:'download', label:'保存图片', url:'{{raw_image_url}}', download:true} // ], // define gallery index (for URL) 定义图库索引(用于URL) galleryUID: galleryElement.getAttribute('data-pswp-uid'), getThumbBoundsFn: function(index) { // See Options -> getThumbBoundsFn section of documentation for more info var thumbnail = items[index].el.getElementsByTagName('img')[0], // find thumbnail pageYScroll = window.pageYOffset || document.documentElement.scrollTop, rect = thumbnail.getBoundingClientRect();  return {x:rect.left, y:rect.top + pageYScroll, w:rect.width}; } }; // PhotoSwipe opened from URL PhotoSwipe从URL打开 if(fromURL) { if(options.galleryPIDs) { // parse real index when custom PIDs are used 使用定制pid时解析真实索引 for(var j = 0; j < items.length; j++) { if(items[j].pid == index) { options.index = j; break; } } } else { // in URL indexes start from 1 在URL索引中，从1开始 options.index = parseInt(index, 10) - 1; } } else { options.index = parseInt(index, 10); } // exit if index not found if( isNaN(options.index) ) { return; } if(disableAnimation) { options.showAnimationDuration = 0; } // Pass data to PhotoSwipe and initialize it gallery = new PhotoSwipe( pswpElement, PhotoSwipeUI_Default, items, options); gallery.init(); }; // loop through all gallery elements and bind events var galleryElements = document.querySelectorAll( gallerySelector ); // console.log(galleryElements.length) for(var i = 0, l = galleryElements.length; i < l; i++) { galleryElements[i].setAttribute('data-pswp-uid', i+1);  galleryElements[i].onclick = onThumbnailsClick; } // Parse URL and open gallery if it contains #&pid=3&gid=1 var hashData = photoswipeParseHash(); if(hashData.pid && hashData.gid) { openPhotoSwipe( hashData.pid , galleryElements[ hashData.gid - 1 ], true, true ); } }; //延迟后执行 避免开始获取不到 setTimeout(function(){ // execute above function initPhotoSwipeFromDOM('.my-gallery'); },600) })();

**需要注意的是每个结构必须一致，方法也要在页面加载以后调用不然点击以后可能会遇到页面跳转道图片地址的情况。

**可根据自己情况进行改动
