Html图像因缩小而未显示

时间:2015-01-11 18:28:10

标签: html image gruntjs minify

我正在使用AngularJS构建Web应用程序,该应用程序是使用Yeoman生成的,我使用Grunt进行缩小,测试等一些任务。 我面临的问题与图像的缩小有关,实际上我想在html中显示一个简单的图像,所以我使用:

<img alt="" src="app/images/Next-SS12.jpg">

问题是,在Grunt执行图像缩小后,图像的名称已更改为:6e5c3c3f.Next-SS12.jpg,但html中的图像名称尚未更新并保留相同。所以这是冲突,因为当我部署应用程序时,图像不会显示。我不反对缩小图像,但如果没有更新引用图像的链接,图像将永远不会显示。

有人知道解决问题的方法吗?

非常感谢你。

grunt任务“Rev”重命名您的图像文件(以避免浏览器缓存,...):

只需删除以下行即可停用图片修订:

'<%= config.dist %>/images/{,/}.*',
