在 rails 中创建一个包含许多链接的下拉列表

问题描述

我有很多链接，例如link1、link2、link3、link4 ...link9.我必须在下拉菜单中添加这些链接.我尝试使用 rails select_tag 和 html 标签

使用 html 选择标签

<option value="link1"><%= link_to "link1", "#",{:remote =>真，'数据切换' =>模态"，数据目标"=>'#modal-window'} %></option><option value="link2"><%= link_to "link2", "#",{:remote =>真，'数据切换' =>模态"，数据目标"=>'#modal-window'} %></option><option value="link3"><%= link_to "link3", "#",{:remote =>真，'数据切换' =>模态"，数据目标"=>'#modal-window'} %></option>......<option value="link9"><%= link_to "link9", "#",{:remote =>真，'数据切换' =>模态"，数据目标"=>'#modal-window'} %></option></选择></span>

如何制作多个链接的下拉列表

解决方案

我是通过以下方式做到的.为此，我参考 bootstrap button dropdowns

<button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">操作 </span><ul class="dropdown-menu" role="menu"><li><%= link_to "link1", "#",{:remote =>真，'数据切换' =>模态"，数据目标"=>'#modal-window'} %></li><li><%= link_to "link1", "#",{:remote =>真，'数据切换' =>模态"，数据目标"=>'#modal-window'} %></li><li><%= link_to "link3", "#",{:remote =>真，'数据切换' =>模态"，数据目标"=>'#modal-window'} %></li><li class="divider"></li><li><%= link_to "link4", "#",{:remote =>真，'数据切换' =>模态"，数据目标"=>'#modal-window'} %></li>

I have many links about for example link1, link2, link3, link4 ...link9.I have to add those links in the drop down. I tried with rails select_tag and also with html tag

Using html select tag

<span class="device_update">
    <select>
      <option value="link1"><%= link_to "link1", "#",{:remote => true, 'data-toggle' =>  "modal", 'data-target' => '#modal-window'} %></option>
      <option value="link2"><%= link_to "link2", "#",{:remote => true, 'data-toggle' =>  "modal", 'data-target' => '#modal-window'} %></option>
      <option value="link3"><%= link_to "link3", "#",{:remote => true, 'data-toggle' =>  "modal", 'data-target' => '#modal-window'} %></option>
           ......

      <option value="link9"><%= link_to "link9", "#",{:remote => true, 'data-toggle' =>  "modal", 'data-target' => '#modal-window'} %></option>
        </select>
    </span>

How can I make drop down lists of many links

解决方案

I did this by following way. For this I refer bootstrap button dropdowns

<div class="btn-group">
      <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
        Action <span class="caret"></span>
      </button>
      <ul class="dropdown-menu" role="menu">
        <li><%= link_to "link1", "#",{:remote => true, 'data-toggle' =>  "modal", 'data-target' => '#modal-window'} %></li>
        <li><%= link_to "link1", "#",{:remote => true, 'data-toggle' =>  "modal", 'data-target' => '#modal-window'} %></li>
        <li><%= link_to "link3", "#",{:remote => true, 'data-toggle' =>  "modal", 'data-target' => '#modal-window'} %></li>
        <li class="divider"></li>
        <li><%= link_to "link4", "#",{:remote => true, 'data-toggle' =>  "modal", 'data-target' => '#modal-window'} %></li>
      </ul>
    </div>
