开放式闪存图2- ID是相同的，因此倍数不显示

Question

每个视图我可以获得一个成功的开放式闪存图。我现在试图支持每个视图的多个开放式闪存图表，但是源代码显示两个生成的DIV的ID相同：

# javascript at top of view
<%= javascript_include_tag "swfobject.js", :cache => true %>

# view itself
<%= @graph.html_safe %>  # html_safe is necessary for Rails 3
<%= @graph2.html_safe %>

# view's source code
<div id='flashcontent_913000'></div> 
  <script type="text/javascript"> 
    swfobject.embedSWF(
    "/open-flash-chart.swf","flashcontent_913000",
    "440", "310", "9.0.0", "expressInstall.swf",
    {"data-file":"/analytics%2Fpie1"}, {}, {} );
  </script> 
</div> 
<br /> 

<div id='flashcontent_913000'></div> 
  <script type="text/javascript"> 
    swfobject.embedSWF(
    "/open-flash-chart.swf","flashcontent_913000",
    "440", "310", "9.0.0", "expressInstall.swf",
    {"data-file":"/analytics%2Fpie2"}, {}, {} );
  </script> 
</div>

#controller
respond_to do |wants|
  wants.html {
    @graph = ofc2( 440, 310, 'analytics/pie1' )
    @graph2 = ofc2( 440, 310, 'analytics/pie2' )
  }
end
def pie1
... # functioning when put in the view alone
end
def pie2
... # functioning when put in the view alone
end

因为ID是相同的， <%= @graph.html_safe %> 尝试渲染Graph2和失败，并且Graph2根本不显示。我需要获取OFC2来生成不同的ID。我该如何完成？

Answer 1

事实证明，您可以在“ Analytics/Pie1”之后立即指定控制器中的ID。通过专门指定ID，我们消除了生成相同数字的算法的任何机会，因此无法显示图像。

例子： @graph = ofc2( 440, 310, 'analytics/pie1', '/', 'my_unique_div' )
