Ruby 的助手

我正在为一些剪贴板复制代码制作一个助手。我希望剪贴板复制视图中生成的 url。

例如，以下是在视图中有效的链接：

<%= link_to event_path(event.id) %>

它在视图中工作得很好。我很难弄清楚该把它放在哪里作为助手。我在助手中传递一个变量，那么我应该将其放入视图中并将其传递给变量，还是应该将其放入助手中？现在它在助手中，我得到正常的文本。

这是 helper.rb 文件：

def clipboard_copy(text = nil, bgcolor='#FFFFFF')
  html = <<-EOF
        ...
    <param NAME="FlashVars" value="text=#{text}">
           ...
           FlashVars="text=#{text}"
           ...
EOF
html.html_safe
end

我从视图中调用它：

<%= clipboard_copy %>

谢谢！

原文

I am making a helper for some clipboard copy code. I would like the clipboard to copy a url that is generated in the view.

For example, here is the link that works in the view:

<%= link_to event_path(event.id) %>

It works just fine in the view. I am having a hard time figuring out where to put it for the helper. I am passing a variable in my helper, so should I put it in the view and pass it to the variable or should I put it in the helper? Right now it's in the helper and I get normal text back.

Here is the helper.rb file:

def clipboard_copy(text = nil, bgcolor='#FFFFFF')
  html = <<-EOF
        ...
    <param NAME="FlashVars" value="text=#{text}">
           ...
           FlashVars="text=#{text}"
           ...
EOF
html.html_safe
end

and I am calling it from the view with:
