jQuery版:

 <link rel="stylesheet" href="css/viewer.min.css" rel="external nofollow"  rel="external nofollow" >
 <script src="js/jquery.min.js"></script> 
 <script src="js/viewer.min.js"></script>

npm,直接install

npm install viewerjs

4.2 简单demo

这里为我用的是js版本,简单做了一个demo

                show: function () {
                    viewer.update();
                }
            });
            $("body").on("click", ".viewer-container", function (e) {
                viewer.hide()
            });
