ie8

IE8 is more strict about declaring document types, as shown in the following code.

<script type="text/javascript"> 
                function osdo(str){ 
                document.getElementById("os").value=str; 
                } 
                </script> 
<input name="ostmp" type="radio" value="" onclick="osdo(&#39;&#39;)" />清空
