fastadmin 框架中图片点击放大

fastadmin的原生图片预览,重新打开一个窗口太麻烦，使用layui做一个弹窗式的图片预览

1、将下面代码放在backend-init.js文件中

 

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

$('body').on('click', '[data-tips-image]', function () {         var img = new Image();         var imgWidth = this.getAttribute('data-width') || '480px';         img.onload = function () {             var $content = $(img).appendTo('body').css({background: '#fff', width: imgWidth, height: 'auto'});             Layer.open({                 type: 1, area: imgWidth, title: false, closeBtn: 1,                 skin: 'layui-layer-nobg', shadeClose: true, content: $content,                 end: function () {                     $(img).remove();                 },                 success: function () {                   }             });         };         img.onerror = function (e) {           };         img.src = this.getAttribute('data-tips-image') || this.src;     });

　　

2、页面的img标签中添加 data-tips-image，点击时自动弹出图片预览

<img src="{$goods.image}" data-tips-image  alt="">
