在点击链接的时候，可以使用history进行页面的返回：

在rails可以这样：

&lt;%= button_tag <span style="color:#abe338">&#39;返回&#39;</span>, <span style="color:#dcc6e0">class</span>: &#39;<span style="color:#00e0e0">btn</span> <span style="color:#00e0e0">btn</span>-<span style="color:#00e0e0">primary</span>&#39;, <span style="color:#00e0e0">style</span>: &#39;<span style="color:#00e0e0">width</span>: 150<span style="color:#00e0e0">px</span>; <span style="color:#abe338">float:</span> left; background-<span style="color:#abe338">color:</span> white; <span style="color:#abe338">color:</span> <span style="color:#d4d0ab">#0d6efd;&#39;, onclick: &#39;goBack()&#39; %&gt;</span>

然后加入js即可：

<span style="color:#dcc6e0">function</span> <span style="color:#00e0e0">goBack</span>() {
history.back();
}
