点击预览放大图片(photoswipe插件)

图片预览插件 https://photoswipe.com/documentation/getting-started.html

简单适用方法

一引入文件

<link rel="stylesheet" href="../res/photoswipe/4.1.1/photoswipe.min.css">
<link rel="stylesheet" href="../res/photoswipe/4.1.1/default-skin/default-skin.min.css">
<script src="../res/photoswipe/4.1.1/photoswipe.min.js"></script>
<script src="../res/photoswipe/4.1.1/photoswipe-ui-default.min.js"></script>

或者（直接使用cdn）

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/photoswipe/4.1.1/photoswipe.min.css">
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/photoswipe/4.1.1/default-skin/default-skin.min.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/photoswipe/4.1.1/photoswipe.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/photoswipe/4.1.1/photoswipe-ui-default.min.js"></script>

二在body内添加div

<!-- Root element of PhotoSwipe. Must have class pswp. -->
<div class="pswp" tabindex="-1" role="dialog" aria-hidden="true">

    <!-- Background of PhotoSwipe. 
         It's a separate element, as animating opacity is faster than rgba(). -->
    <div class="pswp__bg"></div>

    <!-- Slides wrapper with overflow:hidden. -->
    <div class="pswp__scroll-wrap">

        <!-- Container that holds slides. PhotoSwipe keeps only 3 slides in DOM to save memory. -->
        <div class="pswp__container">
            <!-- don't modify these 3 pswp__item elements, data is added later on -->
            <div class="pswp__item"></div>
            <div class="pswp__item"></div>
            <div class="pswp__item"></div>
        </div>

        <!-- Default (PhotoSwipeUI_Default) interface on top of sliding area. Can be changed. -->
        <div class="pswp__ui pswp__ui--hidden">

            <div class="pswp__top-bar">

                <!--  Controls are self-explanatory. Order can be changed. -->

                <div class="pswp__counter"></div>

                <button class="pswp__button pswp__button--close" title="Close (Esc)"></button>

                <button class="pswp__button pswp__button--share" title="Share"></button>

                <button class="pswp__button pswp__button--fs" title="Toggle fullscreen"></button>

                <button class="pswp__button pswp__button--zoom" title="Zoom in/out"></button>

                <!-- Preloader demo https://codepen.io/dimsemenov/pen/yyBWoR -->
                <!-- element will get class pswp__preloader--active when preloader is running -->
                <div class="pswp__preloader">
                    <div class="pswp__preloader__icn">
                      <div class="pswp__preloader__cut">
                        <div class="pswp__preloader__donut"></div>
                      </div>
                    </div>
                </div>
            </div>

            <div class="pswp__share-modal pswp__share-modal--hidden pswp__single-tap">
                <div class="pswp__share-tooltip"></div> 
            </div>

            <button class="pswp__button pswp__button--arrow--left" title="Previous (arrow left)">
            </button>

            <button class="pswp__button pswp__button--arrow--right" title="Next (arrow right)">
            </button>

            <div class="pswp__caption">
                <div class="pswp__caption__center"></div>
            </div>

          </div>

        </div>

</div>

三定义js方法

var openPhotoSwipe = function(idx) {
	    var pswpElement = document.querySelectorAll('.pswp')[0];
	    
	    
	    var arr=myOrderInfo.obj.paymentVoucher.split(",");//arr=['http://xxx/a.jpg','http://xxx/b.jpg']"
	    var items2=[];
	    for(var i=0;i<arr.length;i++){
	    	var ob={
		            src: arr[i],
		            w: 1024,
		            h: 1024
		        };
	    	items2[items2.length]=ob;
	    }
	    

	    // build items array
	    var items = [
	        {
	    html: '<div class="hello-slide"><h1>Hello world <a href="http://example.com">example.com</a></h1></div>'
	  },
	        {
	            src: 'aa.jpg',
	            w: 1024,
	            h: 1024
	        }
	    ];
	    
	    
	    // define options (if needed)
	    var options = {
	    	index:idx,//展示第几个(下标从0开始)
	       // history & focus options are disabled on CodePen        
	        history: false,
	        focus: false,

	        showAnimationDuration: 0,
	        hideAnimationDuration: 0
	        
	    };
	    
	    var gallery = new PhotoSwipe( pswpElement, PhotoSwipeUI_Default, items2, options);
	    gallery.init();
	};
