<%= link_to image_tag("icon_delete.png", :border => 0), user, method: :delete ,data: { confirm: 'Are you sure delete ' + user.email } %>
当用户单击此链接时，我想要一个自定义确认对话框，而不是简单地显示confirm('Are you are').
我读过很多帖子，例如http://lesseverything.com/blog/archives/2012/07/18/customizing-confirmation-dialog-in-rails/。但是，我遇到了问题Sprockets::EncodingError。
有更好的解决方案吗？
更新
在实现自定义确认对话框之前一切正常，编码成功后，这次
<%= link_to image_tag("icon_delete.png", :border => 0), user, method: :delete ,data: { confirm: 'Are you sure delete ' + user.email } %>
实际上，当我单击删除图标时，没有弹出显示，并且此链接没有在 UserController 中调用 destroy()。它在 UserController 上调用了 show()。这是怎么回事？
$.rails.allowAction = (link) ->
return true unless link.attr('data-confirm')
$.rails.showConfirmDialog(link) # look bellow for implementations
false # always stops the action since code runs asynchronously
$.rails.confirmed = (link) ->
link.removeAttr('data-confirm')
link.trigger('click.rails')
$.rails.showConfirmDialog = (link) ->
message = link.attr 'data-confirm'
html = """
<div class="modal" id="confirmationDialog">
<div class="modal-header">
<a class="close" data-dismiss="modal">×</a>
<h3>Are you sure Mr. President?</h3>

$(html).modal()
$('#confirmationDialog .confirm').on 'click', -> $.rails.confirmed(link)
