代码如下
<script language="JavaScript">
for ( var i=0;i < navigator.mimeTypes.length; i++){
if(navigator.mimeTypes[i].enabledPlugin != null){
document.write ("<br></em><font size='+2'>"+
navigator.mimeTypes[i].type+"<br>");
document.write("<font size='+1'>
Enabled Plugin Name: <em>"+
navigator.mimeTypes[i].enabledPlugin.name+"<br>");
document.write("</em>Description: "+ "<em>"+
navigator.mimeTypes[i].description+
"<br></em>Suffixes: "+ "<em>"+
navigator.mimeTypes[i].suffixes+"<br>");
}
}
</script>
怎么会看不到任何结果类，如果是错的那我返回一个值又应该怎么写？else return false?
没反映的
