Question

点击索引提交按钮的颜色＆＃34; New Value＆＃34;变化与变化保持灰色，这是访问过的链接的颜色，而 _form提交按钮保持相同的颜色白色。

我希望按钮保持白色，而所有其他链接应根据是否被访问来改变颜色。

你能帮帮我吗？

index.html.erb

＆＃13;

  <div class="form-group">
    <%= link_to 'New Value', new_value_path, class: "btn btn-primary" %>
  </div>

＆＃13;

_form.html.erb

＆＃13;

  <div class="form-group">
    <%= f.submit class: "btn btn-primary" %>
  </div>

Answer 1

在索引页面中，您使用的是link_to项，这将为您提供<a>的行为。你给a的CSS作为

a {
  color: #000;
  &:visited {
    color: #666;
  }
  &:hover {
    color: #fff;
    background-color: #000;
  }
}

所以颜色会根据你给出的css而改变。

在_form页面中，您已将input type与submit按钮一起使用，并与类btn css链接。所以提交按钮正在消耗css。

如何使按钮保持相同的链接颜色？
