Question

按钮在FF，Chrome，Safari中显示正常。将无法在IE 7/8中呈现。

这是我给出的代码：

<!DOCTYPE html>
  <html>
    <head>
      <link rel="stylesheet" type="text/css" href="RadMenu.css">
    </head>
  <body>
     <svg xmlns="http://www.w3.org/2000/svg" version="1.1">
     <g id="g" shape-rendering="inherit" pointer-events="all">
     <circle cx="400" cy="210" r="25.6" fill="white" stroke="#505055" strokewidth="2">
     </circle>
       <foreignObject x="383" y="192" width="32" height="32" id="PBtn16400210">
         <html>
         <body>
            <div class="Btn3D" title="" style="width: 101%; height: 100%; background-color:   rgb(218, 184, 82); text-align: center; vertical-align: middle; background-position: initial initial; background-repeat: initial initial;"></div>
         </body>
         </html>
      </foreignObject></g>
     </svg> 
   </body>
</html>

Answer 1

Internet Explorer在v9之前不支持SVG（即使那时它只是基本支持）。

Answer 2

Raphaël为您进行SVG到VML转换，它了解原生SVG。听起来好像学习VML在你的情况下是值得的。

需要注意的一件重要事情是IE 9，也不支持10支持SVG中的异物。虽然SVG规范中是可选的，但在支持某些功能时它可能是一个严重的问题。所有其他主流浏览器都支持它。事实上，您的代码在任何IE版本中都无法正确呈现。

Answer 3

IE在IE9中添加了对SVG的支持。以前的版本不支持它，也不会工作。 IE确实支持自己的称为VML的矢量格式，因此可以编写polyfill。一个这样的项目是SVGWeb，它使用Flash来实现支持。根据您的需要，它应该运作良好。

有关详细信息，请参阅http://code.google.com/p/svgweb/。

Answer 4

您还可以考虑使用Ample SDK作为SVG内容的垫片。例如：SVG Tiger

Answer 5

以下是解决方案：在SVG之后添加此代码。
