Netsuite用户事件脚本为JavaScript全局变量获取空值

Question

我有一个名为itemId的JavaScript全局变量(此itemId是一个具有键值对的对象),此对象将存储标准项记录详细信息.

我能够在"用户事件脚本加载前事件"中存储此值,并尝试在"提交前事件"中访问全局变量"itemId",但此itemId(Object)变为空值.

当试图使用Key获取此对象的值时,它显示错误:":无法读取属性"ItemQuantityTolerance"from undefined"

码:

SuiteScript版本:2.0

 var itemId = new Object();

 function beforeLoad(scriptContext) {

      try {

          var IR_Record = scriptContext.newRecord;
          var form = scriptContext.form;
          form.clientScriptFileId = 50137;

          if (IR_Record != null && IR_Record != '' && IR_Record != undefined) {


              var ItemsId = new Array();
              var IR_LineItemCount = null;
              var lineNumber = null;

              IR_LineItemCount = IR_Record.getLineCount('item');
              log.debug('Value', 'IR_LineItemCount : ' + IR_LineItemCount);

              if (IR_LineItemCount != null && IR_LineItemCount != '' && IR_LineItemCount != undefined) {

                  for (var i = 0; i < IR_LineItemCount; i++) {

                      lineNumber = i;
                      log.debug('Value', 'LineNumber : ' + lineNumber);

                      var IR_ItemId = IR_Record.getSublistValue({
                          sublistId: 'item',
                          fieldId: 'item',
                          line: i
                      });

                      ItemsId[lineNumber] = IR_ItemId;
                      log.debug('Value', 'IR_ItemId : ' + IR_ItemId);

                  }

                  if (ItemsId != null && ItemsId != '' && ItemsId != undefined) {

                      log.debug('Value:', 'ItemsId:' + ItemsId);

                      getItemToleranceValues(ItemsId);

                  }

              }


          }

      } catch (exception) {
          log.debug("Value :", "Before-Load Error :", exception.message);
          throw exception.message;
      }


  }

  function getItemToleranceValues(ItemsId) {

      try {

          var ItemDetialsSearch = "";
          var ItemSearchResults = "";

          var Item_Id = null;
          var Item_Name = "";




          ItemDetialsSearch = search.create({
              type: 'item',
              filters: ['internalid', 'anyof', ItemsId],
              columns: ['internalid', 'itemid']
          });

          if (ItemDetialsSearch != null && ItemDetialsSearch != '' && ItemDetialsSearch != undefined) {

              ItemSearchResults = ItemDetialsSearch.run().getRange(0, 200);

              if (ItemSearchResults != null && ItemSearchResults != '' && ItemSearchResults != undefined) {


                  for (var i = 0; i < ItemSearchResults.length; i++) {

                      var itemDetails = new Object();

                      Item_Id = ItemSearchResults[i].getValue('internalid');

                      Item_Name = ItemSearchResults[i].getValue('itemid');

                      if (Item_Name != null && Item_Name != '' && Item_Name != undefined) {



                          itemDetails['ItemName'] = Item_Name;

                      }


                      itemId[Item_Id] = itemDetails;

                  }

                  log.debug("itemId:", itemId);

              }

          }


      } catch (exception) {

          log.debug("Value:", "Item-Tolerance-Value Error:" + exception.message);
          throw exception.message;
      }

  }


  function beforeSubmit(scriptContext) {

      try {


          var IR_Record = scriptContext.newRecord;
          var itemName = "";
          if (IR_Record != null && IR_Record != '' && IR_Record != undefined) {

              if (itemId != null && itemId != '' && itemId != undefined) {

                  log.debug("itemId:", itemId);


                  itemName = itemId[IR_ItemId]['ItemName']; // Getting Empty Values at this point, eventhough it is global variable with values

                  log.debug('Value', 'itemName : ' + itemName);



              }

          }

      }catch(exception){

          throw exception.message;

      }

itemId对象的示例值:

{
   337: {
      ItemName: "Apple",

   },
   359: {
      ItemName: "Orange"

   }
}

如何访问全局变量itemId使用它属性"ItemName"获取值.

提前致谢.

您错误地理解了脚本执行生命周期.在服务器端,在加载之前,在提交之前和提交之后执行都是完全独立的.它看起来像您正在加载的itemId的唯一的地方是通过调用getItemToleranceValues你的beforeLoad脚本,但你访问你的空值beforeSubmit的脚本.

如果有理由在beforeLoad脚本中加载该值,则可以将该值缓存在会话变量中,然后在beforeSubmit脚本中检索它.请参阅N /运行时模块中的Session.get/set
