使用link_to之后添加了额外的末端锚标记

Question

For some reason rails is generating additional anchor tags after I use link_to inside an HTML anchor tag. Is this HTML design or rails constrain.?

<li>
                <a id="user-menu" href="#">
                    <%=current_user.first_name%>
                    <div id="bubblemenu" class="lotusBubble-content" style="display:none"> 
                      <ul>
                          <li><%= link_to "My Profile", current_user %></li>
                          <li>My Bookmarks</li>
                          <li>My Active</li>
                          <li>My Expired</li>
                      </ul>
                    </div>
                </a>
            </li>

This generates a HTML like this

            <li>
                <a id="user-menu" href="#">Srikanth</a>
                  <div id="bubblemenu" class="lotusBubble-content" style="display:none">
                              <a id="user-menu" href="#"> </a>
                              <ul>
                                    <a id="user-menu" href="#">
                                    </a>
                                    <li><a id="user-menu" href="#"></a><a href="/user.1">My Profile</a></li>
                                    <li>My Bookmarks</li>
                                    <li>My Active</li>
                                    <li>My Expired</li>
                              </ul>

why is there so anchor tags added automatically ?

Answer 1

这是由于您使用的是link_to指令，该函数在执行时会自动创建一个锚点ta

Answer 2

Just saw this restriction. Anchor inside an anchor is not permitted as per HTML standards. If at all something like that occurs, then the browsers atomically ends the outer anchor
