Rails 'button_tag' 定义变量

Question

<%= 
 button_tag class: "btn btn-primary",
 data: { toggle: "modal", target: "#exampleModal", name: member.name } do
    modal_member = Member.find(member.id)
    content_tag(:b, 'Open Modal')
 end           
 %>

我要创建变量名'modal_member' button_tag

因为 bootstrap 模式但它不起作用

我觉得定义代码做的不好

我的目标是定义变量或将变量传递给按钮或 link 标签

我建议将模态结构直接插入到您的 erb 文件中，然后用您想要的数据填充它。除非你是通过js触发的，那就另当别论了。

<%= 
 button_tag class: "btn btn-primary",
 data: { toggle: "modal", target: "#exampleModal", name: member.name } do
    content_tag(:b, 'Open Modal')
 end           
 %>
 <div class="modal" tabindex="-1" role="dialog">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title">Modal title</h5>
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">
        <p> <%= member.name %> or whatever data you want</p>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-primary">Save changes</button>
        <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
      </div>
    </div>
  </div>
</div>
