 if(row.copy == '1'){
 return '<p><input type="text" id="copyQty'+row.dataCode+'" value="" placeholder="请输入打印数量" class="isAuto" onfocus="copyQtyCheck(this,\''+row.dataCode+'\')"/></p>';
 }else{
 return '<p><input type="text" id="copyQty'+row.dataCode+'" value="" disabled="true" placeholder="请输入打印数量" class="isAuto" onfocus="copyQtyCheck(this,\''+row.dataCode+'\')"/></p>';

 //是否附件触发
 function copyCheck(doc,dataCode){
  var confirmId="confirm"+dataCode;
  var copyQtyId="copyQty"+dataCode;
  var copyId="copy"+dataCode;
  if($(doc).attr("checked") == "checked"){
   $("#" + copyQtyId + "").val("");
   $("#" + copyQtyId + "").attr("disabled", true);
   $("#" + copyId + "").attr("checked", false);
  }else{
   //点亮附件数输入框
   $("#" + copyQtyId + "").attr("disabled", false);
   $("#" + copyId + "").attr("checked", "checked");
