use disabled and title attribute, for example:<a href="http://www.csdn.net" title="doesn't support yet" disabled >CSDN</a> <img src="zip.gif" title="doesn't support yet" onclick="location.href='http://www.csdn.net';" disabled> <script language="javascript"> function document.onclick() { if (event.srcElement.disabled) return false; } </script>
<img src="zip.gif" title="doesn't support yet" onclick="location.href='http://www.csdn.net';" disabled>
<script language="javascript">
function document.onclick()
{
if (event.srcElement.disabled)
return false;
}
</script>
<a href=# title="你要提示的内容">一些文字</a>
如果要在文本上加提示,则楼上的title属性没错
