推荐答案

All Rails 的 file_field 帮助器可以更轻松地创建文件输入，而不必直接编写 HTML(即.).不幸的是，文件输入的样式不太好，而且按钮特别容易卡在浏览器定义它应该看起来的方式上.

All Rails' file_field helper does is make it easier to create a file input, rather than having to code HTML directly (ie. <input type="file" ...>). Unfortunately, the file input is not very styleable, and the button especially tends to be stuck to the way the browser defines it should look.

但是，有一些技巧/技巧可以通过使用 CSS 和 Javascript 来欺骗浏览器使浏览按钮看起来像您想要的样子.您可以在 quirksmode 上查看有关它的文章.但是，由于这使用了 CSS opacity 属性，因此输入在不支持它的浏览器中看起来不正确.此外，如本文所述，这种方法还存在一些其他问题.

However, there are some techniques/hacks for tricking the browser into making the browse button look how you want it, by making use of CSS and Javascript. You can take a look at an article about it on quirksmode. However, as this makes use of the CSS opacity property, the input will not look right in browsers that do not support it. As well, there are some other problems with this approach, as outlined in the article.
