jquery – Ruby on Rails,选择并取消选中所有复选框

我有一个按钮,当我点击它时,我希望选中所有复选框.通过单击第二次,必须取消选中所有复选框.

<script type='text/javascript'>
   $('#check_all').on("click",function(){ $('input[type="checkBox"]').click(); });
   </script>



<%= form_tag save_share_patients_clinicdb_grp_pats_path,method: :post do %>

<%= hidden_field_tag 'to_share_group',@to_shr_group%>
<button type="button" id="check_all" class="btw"><%="check all/Uncheck all"%></button>

    <%@pat_ids.each do |pat_id|
    %>  
        <%= check_Box_tag "to_share_patients[]",pat_id.mk1%> <%=pat_id.mk1%>
        <br/>
    <%end%>

<%= button_tag :class => "btn btn-warning",:name => 'share' do %> <%= t "share" %> <% end %> 
<%end%>

有些东西在这里不起作用.你能帮我吗？

编辑：

$('#check_all').on("click",function(){ alert("aaa"); });
