<script type="text/javascript">      

  

    document.onkeydown=keyDownSearch;  

      

    function keyDownSearch(e) {    

        // 兼容FF和IE和Opera    

        var theEvent = e || window.event;    

        var code = theEvent.keyCode || theEvent.which || theEvent.charCode;    

        if (code == 13) {    

            getTableListData();//具体处理函数    

            return false;    

        }    

        return true;    

    }  

</script>  

  

如果只是针对某个DIV层应用回车查询的话,可以将:  

 document.onkeydown=keyDownSearch;  

改成:  

document.getElementById('层ID').onkeydown=keyDownSearch;
