根据ID填充文本框

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>
