前台：<script type="text/javascript">    function func_load_remark(sr_id){    if(sr_id!=0){        $.getJSON("loadSrRemark.do?date="+new Date(), {srid:sr_id}, function(srmain){        $("#bparemark").val(srmain.bpa_remark);        $("#itdremark").val(srmain.itd_remark);        $("#bugremark").val(srmain.bu_remark);        $("#itoremark").val(srmain.ito_remark);        });    }else{        $("#bparemark").val("");        $("#itdremark").val("");        $("#bugremark").val("");        $("#itoremark").val("");        }    }    function check(){    if($("#srid").val()=="0"){    alert("请选择SR_ID!");    $("#srid").focus();    return false;    }    return true;    }        </script>
