铁路局向Ruby提供星体作为彩色黑轴值
原标题:Rendering a string as a color hex value in Ruby on Rails

我从XML档案中获得了超重价值,我正试图利用这种超值作为数据表的背景图。 然而,在IE8中,它一直作为扼杀手段。

当我使用时

<%= h(@dhex1[k]) %>

原文照发。

<%hex>A8960A<%/hex> with hex tags (note % sign are so browser do not consider they are tags)

browser。 我曾尝试过

<td style="background-color:#<%=h(@dhex1[k].to_s)%>">    
<td style="background-color:#<%=h(@dhex1[k])%>">    
<td style="background-color:#<%=@dhex1[k]%>">
<td style="background-color:<%=@dhex1[k]%>">

然而,它不会成为一种背景。 如何储存XML本身的价值的标签,我正在使用

@hex1 = XPath.match( xmldoc, "///hex" )

to get the hex value, but 原文照发。A8960A. What do I need to change?

最佳回答

您的描述显示,@dhex1[k]含有不想要的xml元素。 要么在贵方提取价值的地方,如在哪里,就删除了这些价值。

@hex1 = XPath.match(xmldoc,  //hex/text() )

或之后,

<td style="background-color:#<%= @dhex1[k].gsub(/<.+?>/,   ) %>">
