先看看弹窗效果，如下：
//放大图片 $(page).on('click','.popupImage img',function () { var that = $(this); that.popupImage({ this:that, width:"200px" }) }); //相册弹窗 $.fn.popupImage = function (obj) { var $this = obj.this; var sj_w = $this[0].naturalHeight; var src = $this.attr('src'); var h = $('body').height(); var w = $('body').width(); var padding = 10; var shadeW = w - padding*2; var img = '',shade = ''; img = '<div >' + '<img src="'https://www.jb51.net/article/+src+'"/></div>'; shade = '<div></div>'; $('body').append(shade); $('body').append(img); $('.popup-image').on('click',function () { $('.popup-image').remove(); $('.shade').remove(); }) };
