<table id="approveTable"> <tr> <td> <input type="radio" name="action" value="1" checked="checked" onclick=‘$("#selectRow").css("visibility","visible");‘/>成功 </td> <td> <input type="radio" name="action" value="0" onclick=‘$("#selectRow").css("visibility","hidden");‘/>失败 </td> </tr> </table>
这种方式checked是起作用,但如果不把控件包在td中就不起作用了,如下：
<table id="approveTable"> <tr> <input type="radio" name="action" value="1" checked="checked" onclick=‘$("#selectRow").css("visibility","visible");‘/>成功 <input type="radio" name="action" value="0" onclick=‘$("#selectRow").css("visibility","hidden");‘/>失败 </tr> </table>
