根據ID填充文本框的實例代碼

　　前台

復制代碼 代碼如下:
<script type="text/javascript">
     function func_load_remark(sr_id){
     if(sr_id!=){
        $getJSON("loadSrRemarkdo?date="+new Date() {srid:sr_id} function(srmain){
        $("#bparemark")val(srmainbpa_remark);
        $("#itdremark")val(srmainitd_remark);
        $("#bugremark")val(srmainbu_remark);
        $("#itoremark")val(srmainito_remark);
        });
     }else{
        $("#bparemark")val("");
        $("#itdremark")val("");
        $("#bugremark")val("");
        $("#itoremark")val("");
     }
     }
     function check(){
     if($("#srid")val()==""){
     alert("請選擇SR_ID!");
     $("#srid")focus();
     return false;
     }
     return true;
     }
     </script>
