pdf导出 预览、直接打印、打印加预览

前台：

 var xueurl = "fileFormatController.do?getXbDetail_print&id=&codes=" + rowsData[0].arrivalLabelcode;
 $.messager.defaults = { ok: "确定", cancel: "取消" };
 const html = '<p id="p"><label for="r">请选择打印方式</label></p><p id="p">'
         + '      <label for="r"><input type="radio" id="r" name="impTypess" value="1" checked>'
         + ' 直接打印</label>'
         + '      <label for="r1"><input type="radio" id="r1" name="impTypess" value="2">'
         + ' 预览</label></p>  </p>'
         + '      <label for="r2"><input type="radio" id="r2" name="impTypess" value="3" >'
         + ' 打印并预览</label></p>  </p>'
  $.messager.confirm("请选择打印方式", html, function (data) {
   if (data) {
        var impTypess = $("input[name='impTypess']:checked ").val();
        xueurl+='&impTypess='+impTypess;
        if(impTypess=='2'){//预览
            window.open(xueurl);
        }else if(impTypess=='3'){//预览并打印
            window.open(xueurl);
            window.location.href = 'fileFormatController.do?getXbDetail_print&id=&codes=" + rowsData[0].arrivalLabelcode'+'&impTypess=1';
        }else if(impTypess=='1'){//打印
            window.location.href = 'fileFormatController.do?getXbDetail_print&id=&codes=" + rowsData[0].arrivalLabelcode'+'&impTypess=1';
        }
    }
 });
