本公开实施方式中的多个装置之间所交互的消息或者信息的名称仅用于说明性的目的，而并不是用于对这些消息或信息的范围进行限制。
参考图1，图1示出了本公开一实施例提供的控制数据块的方法，包括步骤S12和步骤S14。
步骤S12：响应于第一文档中的第一数据块被执行目标操作，确定所述第一数据块是否与第二文档具有引用关系；其中，所述目标操作用于在数据块下插入、删除、移动或替换子数据块。
在一些实施例中，数据块(Block)作为对在线文档进行编辑的基本单元，数据块可以用于显示文字信息、图像信息或多媒体信息等信息。一个数据块可以用于显示一段文字或多段文字，多个数据块可以是另一个数据块的子数据块。
在一些实施例中，第二文档为第一文档以外的其他文档。在一个实施方式中，第二文档可以为第一文档以外的任意一个或多个在线文档。在另一个实施方式中，第二文档可以为第一文档以外特定的一个或多个在线文档。
需要说明的是，除非另有说明，本实施例中数据块与文档之间的引用关系包括该数据块的一个或多个子数据块被该文档引用，或者，该数据块的一个或多个子数据块引用自该文档。
参见图2，图2示出了根据本公开一实施例的在线文档的示意图。在第一在线文档210中，数 据块10、11、12、13和20依次分别显示有“文本内容A1”“文本内容A2”“文本内容B2”“文本内容C2”和“文本内容B1”等文本信息。其中，数据块11、12和13为第一数据块10的子数据块，第一数据块10和第二数据块20为数据块30的子数据块。此外数据块30还可以为其他数据块的子数据块，本实施例在此不做限制。第二在线文档220引用了第一在线文档210的数据块11和12，即，第二在线文档220与第一数据块10之间存在引用关系。
图4示出了根据本公开一实施例提供的数据块的节点关系的示意图。在图4中，每个节点可以对应一个数据块，根节点R下有节点A0、B0和C0，即表示根节点是节点A0、B0和C0的父节点；节点A0下有节点A1和B1，即节点A0是节点A1和B1的父节点；节点A1下有节点A2、B2和C2，即表示节点A1是节点A2、B2和C2的父节点；节点A2下有节点A3和B3，即表示节点A2是节点A3和B3的父节点；节点B2下有节点C3，即表示节点B2是节点C3的父节点。
在一个具体实施方式中，目标操作可以支持在列表中插入、删除、移动或替换项目，并根据需要对相邻的列表项目进行洗牌(Shuffling)。例如，指令“{p:[path,idx],li:obj}”可以用于在列表中索引值为“idx”处的项目之前插入对象“obj”；指令“{p:[path,idx],ld:obj}”可以用于在列表中删除索引值为“idx”的对象“obj”；指令“{p:[path,key],oi:obj}”可以用于将对象“obj”插入到[path]处的对象中；指令“{p:[path,key],od:before,oi:after}”可以用于将对象“after”替换对象“before”。
下面以图4为例进行说明，如果想要从数据块A1下删除数据块B2，则可以采用指令{p:["children",1],ld:"B2"}；如果想要在数据块A2与数据块B2之间插入数据块D2，则可以采用指令{p:["children",1],li:"D2"}；如果想要将数据块A2和B2替换为数据块D2和E2，则可以使用{p:[path,key],od:before,oi:after}指令。
步骤S14：响应于确定所述第一数据块与第二文档具有引用关系，则基于所述目标操作，确定所述第一文档中至少一个数据块与所述第二文档的引用关系。
在一些实施例中，步骤S14包括：基于所述目标操作，更新所述第一数据块与所述第二文档的引用关系。若所述目标操作使所述第一数据块下的全部的或数量最多的被所述第二文档引用的被引用数据块移动至所述第一文档中第二数据块下，则步骤S14还包括：基于所述目标操作，确定所述第二数据块与所述第二文档的引用关系。
在一些实施例中，可以基于所述目标操作所针对的数据块在所述第一数据块下与所述第一数据块的其他子数据块的相对位置关系，更新所述第一数据块与所述第二文档的引用关系。
在一些实施例中，可以基于被所述目标操作移动到所述第二数据块下的所述被引用数据块与所述第二数据块的其他子数据块的相对位置关系，确定所述第二数据块与所述第二文档的引用关系。
下面进行示例性说明。
假设第一文档的数据块A1下依次有A2、B2、C2这三个子数据块，第二文档引用了数据块A1下的第2-3个子数据块(即B2和C2)，如果用户在C2后插入或删除了1个子数据块，则第二文档引用的数据块仍为数据块A1下的第2-3个子数据块(即B2和C2)；如果用户在B2前插入了1个子数据块，则第二文档引用的数据块变更为数据块A1下的第3-4个子数据块(即仍为B2和C2)；如果用户删除了子数据块A2，则第二文档引用的数据块变更为数据块A1下的第1-2个子数据块(即仍为B2和C2)；如果用户在B2和C2之间插入了1个子数据块X2，则第二文档引用的数据块变更为数据块A1下的第2-4个子数据块(即变更为B2、X2、C2)。
假设第一文档的第一数据块A1的子数据块A2、B2和C2均一同被第二文档引用，若用户将子数据块A2、B2拖拽至第一文档的第二数据块B1下，并将子数据块C2拖拽至第一文档的第三数据块C1下，则可以创建第二文档与第二数据块B1之间的引用关系。进一步地，若第二数据块B1原本无子数据块，则该引用关系可以进一步确定为第二文档引用数据块B1下的第1-2个数据块；若第二数据块B1原本依次具有子数据块D4和E4，而被引用的子数据块A2、B2被拖拽至子数据块D4、 E4之前，则该引用关系可以进一步确定为第二文档引用数据块B1下的第1-2个数据块；若子数据块A2、B2被拖拽至第二数据块B1原本的子数据块D4、E4之后，则该引用关系可以进一步确定为第二文档引用数据块B1下的第3-4个数据块；若子数据块A2、B2被拖拽至子数据块D4与E4之间，则该引用关系可以进一步确定为第二文档引用数据块B1下的第2-3个数据块。
这样，根据本公开的一个或多个实施例，通过响应于第一文档中的第一数据块被执行目标操作，确定所述第一数据块是否与第二文档具有引用关系，并响应于确定所述第一数据块与第二文档具有引用关系，则基于所述目标操作，更新所述第一文档中至少一个数据块与所述第二文档的引用关系，从而可以实现被引用的数据块的同步更新。
根据本公开的一个或多个实施例，提供了一种控制数据块的方法，包括：
步骤S120：响应于第一数据块被执行目标操作，确定所述第一数据块是否为选区的关联数据块。其中，所述选区被组织成通过选区的关联数据块和选区的范围来描述被引用数据块的位置和范围；所述被引用数据块为被至少一个在线文档引用的数据块；
步骤S140：响应于确定所述第一数据块为选区的关联数据块，则基于所述目标操作重新确定所述选区的关联数据块和/或范围。
根据本公开的一个或多个实施例，可以通过设置选区来描述被引用的数据块的位置和范围。以图4为例进行示意性说明，假设数据块A2、B2和C2的索引值依次为0、1、2，且数据块A2、B2为被引用的数据块，则可以设置选区S的关联数据块(或关联节点)为A1以及选区S的范围为[0,1]，其表示节点A1下的索引值为0的节点(即节点A2)和索引值为“1”的子节点(即节点B2)及其二者之间的子节点(如有)所对应的数据块为被引用的数据块。其中，“0”为起始索引值，“1”为结束索引值，选区的范围为闭区间。
需要说明的是，选区的范围还可以采用其他数值、数值范围以及数值间隔，本实施例在此不做限制。本实施例中的第一数据块可以位于原文中，也可以位于引文中，其中，引文为引用原文的一个或多个数据块的在线文档，本实施例在此不做限制。
在一些实施例中，一个选区用于描述一个数据块或者一组连续的数据块。在一些实施例中，若所述目标操作将所述第一数据块下的全部的或数量最多的所述被引用数据块移动到第二数据块下，将所述选区的关联数据块由所述第一数据块变更为所述第二数据块。
需要说明的是，除非另有说明，本公开提及的“数据块A下/内的数据块”是指数据块A的子数据块，本公开提及的“将数据块A移动到数据块B下/内”是指将数据块A移动到数据块B下/内以使数据块A成为数据块B的子数据块。
在一个具体实施方式中，例如参考图2-3，若用户在第一在线文档210中，将被引用数据块11和12由数据块10下拖拽至数据块20下，则可以将选区的关联数据块由原本的数据块10相应地修改为数据块20。参考图4，若用户将节点A2、B2对应的被引用数据块拖拽至节点B1对应的数据块下，则将选区的关联数据块(或关联节点)由原先的“A1”修改为“B1”。
进一步地，在一些实施例中，基于被所述目标操作移动到所述第二数据块下的所述被引用数据块与所述第二数据块的其他子数据块的相对位置关系，重新确定所述选区的范围。
在一个具体实施方式中，参考图4，选区S的关联数据块为A1，范围为闭区间[0,1]。当用户将被引用数据块A2、B2拖拽数据块B1下时，则先将选区的关联数据块(或关联节点)由原先的“A1”确定为“B1”，然后，可以基于被引用数据块在数据块B1下与数据块B1的其他子数据块的相对位置关系重新确定选区的范围。在本实施方式中，因B1原本无其他子数据块，则选区的范围仍可以为[0,1]。
在另一个具体实施方式中，若数据块B1下原本有其他的子数据块，例如数据块D2，当数据块A2、B2对应的被引用数据块拖拽至数据块D2之后时，则可以将选区的范围的左右区间值相应加1， 更新为[1,2]，其表示节点B1下的索引值(index)为1的节点(即拖拽后的A2)和索引值为“2”的子节点(即拖拽后的A2)及其二者之间的子节点(如有)所对应的数据块为被引用的数据块；当数据块A2、B2对应的被引用数据块拖拽至数据块D2对应的数据块之前，即数据块A2、B2在数据块B1下仍位列前两位时，则选区的范围仍可以为[0,1]。
在一个具体实施方式中，如用户将第一数据块的被引用数据块分别拖拽到其他不同的数据块中，则可以将具有数量最多的被拖拽的被引用数据块作为所述选区的新的关联数据块，并基于所述新的关联数据块下的被引用数据块与其他子数据块的相对位置关系，重新确定所述选区的范围。例如，若第一数据块A1的全部子数据块A2、B2和C2(分别对应索引值0、1、2)均为被引用数据块，则选区S的关联数据块可以为A1、范围可以为[0,2]，当用户将子数据块A2、B2拖拽至第二数据块B1下，并将子数据块C2拖拽至第三数据块C1下，则可以将选区的关联数据块由原先的第一数据块A1修改为第二数据块B1，若第二数据块B1原本无子数据块，则选区的范围为[0,1]，即表示第二数据块B1下的第一个数据块(即拖拽后的子数据块A2)和第二个数据块(即拖拽后的子数据块B2)为被引用的数据块；若第二数据块B1原本具有子数据块D4和E4，而被引用的子数据块A2、B2被拖拽至子数据块D4、E4之前，则选区的范围仍为[0,1]，即表示第二数据块B1下的前两个子数据块为被引用的数据块；若子数据块A2、B2被拖拽至第二数据块B1原本的子数据块D4、E4之后，则选区的范围的左右区间值相应加2，更新为[2,3]，即可以表示第二数据块B1下的第三、四个子数据块为被引用数据块；若子数据块A2、B2被拖拽至子数据块D4与E4之间，则选区的范围的左右区间值相应加1，更新为[1,2]，即可以表示第二数据块B1下的第二、三个子数据块为被引用的数据块。
在一些实施例中，若所述目标操作在所述第一数据块内移动所述被引用数据块，则将所述选区的关联数据块保持不变；基于移动后的所述被引用数据块与所述第一数据块的其他子数据块的相对位置关系，重新确定所述选区的范围。在本实例中，若用户在第一数据块内移动被引用数据块，因没有改变被引用数据块的父数据块，则无需变更选区的关联数据块，并可以基于被引用数据块移动后的位置重新确定选区的范围即可。
根据发明人调查发现，相关在线文档技术提供的实时引用功能并不完善，容易出现被引用部分丢失的问题。例如当用户在线文档中移动或拖拽被其他在线文档引用的内容时，会导致被引用的内容在该其他在线文档中丢失，这是因为一段连续的内容被拖拽往往会被认为其在原文中被删除。
对此，根据本公开的一个或多个实施例，通过选区的关联数据块和选区的范围来描述被引用数据块的位置和范围，并当选区的关联数据块被执行目标操作时，根据所述目标操作重新确定选区的关联数据块和/或范围，从而通过同步更新选区的关联数据块和/或范围，以更新数据块与引用文档之间的引用关系，可以实现被引用的数据块的同步更新。
在一些实施例中，所述目标操作包括第一操作指令，或者第一操作指令和第二操作指令；所述第一操作指令用于编辑第一数据块，所述第二操作指令用于编辑所述第一数据块以外的其他数据块，所述第一操作指令实施于所述第二操作指令之前。
示例性地，所述第一操作指令用于删除所述第一数据块的至少一个子数据块，所述第二操作指令用于往所述第一数据块之外的其他数据块插入至少一个子数据块。
在一个具体实施例中，目标操作包括拖拽操作，该拖拽操作用于将一个或多个子数据块从第一数据块下，拖拽至第一数据块之外的其他数据块下。该拖拽操作可以在第一数据块中删除一个或多个子数据块，并将该一个或多个子数据块插入至其他的数据块下。
在一些实施例中，步骤S140包括：
步骤A10：基于所述第一操作指令确定所述选区的初始更新范围；
步骤A21：若基于所述第一操作指令确定所述选区的初始更新范围为空，且确定从所述第一数 据块下删除的被引用数据块的父数据块变更为所述第一数据块以外的其他数据块，则将包含数量最多的从所述第一数据块下删除的被引用数据块的父数据块作为所述选区的新的关联数据块，并根据针对所述新的关联数据块的所述第二操作指令，确定所述选区的最终范围。
在本实施例中，若基于所述第一操作指令确定所述选区的初始更新范围为空，则意味着第一操作指令将所述第一数据块下的所有被引用数据块删除；若进一步确定从所述第一数据块下删除的被引用数据块的父数据块变更为所述第一数据块以外的其他数据块，则表明第一数据块下被删除的被引用数据块实际上可能被用户拖拽至其他数据块下，因此，通过进一步将包含数量最多的被删除的被引用数据块的父数据块重新确定为作为所述选区的新的关联数据块，并基于针对该新的关联数据块的第二操作指令，可以确定出选区的最终范围。示例性地，可以根据所述新的关联数据块下的所述被删除的被引用数据块与所述新的关联数据块的其他子数据块的相对位置关系，重新确定所述选区的范围。
在一些实施例中，步骤S140包括：
步骤A22：若基于所述第一操作指令确定所述选区的初始更新范围不为空，或确定从所述第一数据块下删除的被引用数据块的父数据块未变更为所述第一数据块以外的其他数据块，则将所述初始更新范围作为所述选区的最终范围。
在本实施例中，若基于所述第一操作指令确定所述选区的初始更新范围不为空，或确定从所述第一数据块下删除的被引用数据块的父数据块未变更为所述第一数据块以外的其他数据块，则意味着第一数据块下的被引用数据块没有被用户执行拖拽操作，而可能是被用户直接删除，则可以直接将基于第一操作指令确定的选区的初始更新范围作为选区最终范围。
优选地，步骤A21和步骤A22中的“从所述第一数据块下删除的被引用数据块”可以进一步为“从所述第一数据块下最后连续被删除的被引用数据块”。通常，用户的拖拽操作产生的操作指令会接连涉及两个数据块，例如，当用户从数据块A下拖拽一个多个子数据块至数据块B时，该拖拽操作会接连触发在数据块A下连续删除一个或多个子数据块的指令，以及在数据块B下连续插入一个或多个子数据块的指令，因而如果数据块A的子数据块被执行拖拽操作，数据块A最后被实施的操作指令必然是用于连续删除其一个或多个子数据块，因为下一个操作指令系针对数据块B的数据块插入指令。因此，在本实施例中，通过确定从所述第一数据块下最后连续被删除的被引用数据块的父数据块是否变更，可以更准确地确定这些被引用数据块是否被用户进行了拖拽操作。
在一个具体实施方式中，可以根据时间顺序记录对数据块的操作指令，并确定针对第一数据块的最后连续的一个或多个操作指令是否为删除操作指令，并确定所述删除操作指令所删除的被引用数据块的父数据块是否变更为第一数据块之外的其他数据块，从而可以确定从所述第一数据块下最后连续被删除的被引用数据块的父数据块是否变更为所述第一数据块以外的其他数据块。
参考图5，图5示出了本公开一实施例提供的控制数据块的方法500的流程图，方法500包括：
步骤S501：记录被执行目标操作的数据块和发生父数据块变更的子数据块；
步骤S502：确定被执行目标操作的数据块是否为选区的关联数据块；
若被执行目标操作的数据块为选区的关联数据块，则执行步骤S503：根据针对所述选区当前的关联数据块的目标操作，更新选区的范围。
若被执行目标操作的数据块不为选区的关联数据块，则可以无需对选区的关联节点和范围进行更新，并处理下一个数据块。
步骤S504：判断步骤S503对选区范围的更新是否是基于第一操作指令进行的更新，且更新结果是否为空，且最后连续被删除的子数据块是否发生了父数据块变更；
若步骤S504判断结果均为是，则执行步骤S505：选取包含数量最多的被删除的被引用数据块的父数据块，作为选区的新的关联数据块。
步骤S505完成后，可以再次执行步骤S503。本领域技术人员可以理解，在本实施例中，第一次执行步骤S503时，是基于针对选区的初始的关联数据快的第一操作指令更新选区的范围，而再次执行步骤S503时，是基于针对选区的新的关联数据块的目标操作(例如第二操作指令)更新选区的范围。
再次执行步骤S503后，步骤S504的判断结果将为否，则执行步骤S506：基于重新确定的所述选区的关联数据块和/或范围确定选区更新信息；
步骤S507：选区更新完成；
步骤S508：广播选区更新信息。
在一些实施例中，所述选区的范围由左端点和右端点描述；步骤S140包括：若所述目标操作用于在所述选区当前的关联数据块下、在所述左端点的左侧增加或删除N个数据块，则所述选区的左端点和右端点对应的数值均增加或减少N；或者，若所述目标操作用于在所述选区当前的关联数据块下、在所述右端点的右侧增加或删除N个数据块，则所述左端点和右端点对应的数值均保持不变；或者，若所述目标操作用于在所述选区当前的关联数据块下、在所述左端点与右端点之间增加或删除N个数据块，则所述选区的右端点对应的数值增加或减少N，且所述左端点对应的数值均保持不变；其中，N为正整数。
下面进行示例性说明。假设数据块A1有子数据块A2、B2、C2和D2，分别对应索引值数组{0,1,2,3}，若数据块B2和C2为被引用数据块，则选区S的关联数据块为A1，选区S的范围为[1,2]，若用户在选区的左端点的左侧，即在数据块B2之前，插入或删除N个数据块，则选区整体后移或前移N位，即选区的左右端点值加N或减N；若用户在选区的右端点的右侧，即在数据块C2之后，插入或删除N个数据块，则选区的左右端点值不变；若用户在左、右端点之间增加或删除N个数据块，则选区的范围为[1,2±N]。
在一些实施例中，步骤S140还包括：若所述目标操作用于在原文内、在所述选区的任意端点处增加N个数据块，则所述选区的范围不变；或者，若目标操作用于在引文内、在所述选区的右端点处增加N个数据块，则所述选区的右端点对应的数值均增加N；所述左端点对应的数值保持不变；或者，若所述目标操作用于在引文内、在所述选区的左端点处侧增加N个数据块，则所述选区的左端点和右端点对应的数值均增加N；其中，所述引文为引用所述原文的一个或多个数据块的在线文档。
参考图2，当某一用户在作为引文的第二在线文档220中在选区的左右端点处增加新的数据块时，该用户的意图往往是在临界点增加被引用数据块的范围，尤其是编辑引文的用户往往也是对数据块进行引用的用户。然而，当某一用户在作为原文的第一在线文档210中在选区的左右端点处(即数据块11、12)增加新的数据块时，因原文中被引用数据块的前后通常还邻接他数据块，因而该用户此时的意图可能并非增加被引用数据块，而是对其他数据块进行处理，尤其是编辑原文的用户可能并非引用数据块的用户。因此，根据本公开的一个或多个实施例，当用户在引文中在选区的端点处插入数据块时，相应扩大选区的范围，而当用户在原文中在选区的端点处增加数据块时，该数据块不作为新增的被引用数据块，从而可以实现更符合用户意图的同步引用更新。
在一些实施例中，如果用户在引文内拖动被引用数据块，则不改变选区的关联节点和范围，即原文内的被引用数据块保持不变；如果用户在引文内、在选区中插入数据块，则可以改变选区的范围，即原文内的被引用数据块也相应反生改变。如图2所示，若用户在第二在线文档220内拖动数据块A2和B2，则第一在线文档210中的数据块A2和B2不发生变化；若用户在第二在线文档220内、在数据块A2和B2之间插入新的数据块X2，则在第一在线文档210中，数据块A2和B2之间亦相应插入新的数据块。
参考图6，图6示出了本公开一实施例提供基于目标操作确定选区的范围的方法的流程图，方 法600包括步骤S601-步骤S610。
步骤S601：确定对选区的关联数据块的目标操作是否包括数据块删除指令，所述数据块删除指令用于在索引值(index)处删除数据块。示例性地，数据块插入指令可以为指令{p:[path,idx],ld:obj}，索引值可以为该指令中“idx”对应的数值。
步骤S602：确定所述索引值是否小于等于选区的结束索引值。
若所述索引值小于等于选区的结束索引值(即index≤end，其中end表示选区的结束索引值)，则执行步骤S603：将所述选区的结束索引值减1(即end＝end-1)
若所述索引值大于选区的结束索引值(即index＞end)，则执行步骤S606：选区范围更新完成。在本步骤中，因删除指令对应的索引值大于选区的结束索引值，意味着数据块的删除指令用于在选区的右边界的右侧删除数据块，不影响选区的范围，无需更新选区。
步骤S604：确定所述索引值是否小于选区的起始索引值。
若所述索引值小于选区的起始索引值(即index＜start，其中start表示选区的起始索引值)，则执行步骤S605：选区的起始索引值减1(即start＝start-1)。在本步骤中，因删除指令对应的索引值小于选区的起始索引值，意味着数据块的删除指令用于在选区的左边界的左侧删除数据块，相当于选区左侧的数据块减少一位，因而选区整体需向左侧挪一位，即选区的起始索引值和结束索引值最终均减一。
若所述索引值大于等于选区的起始索引值(即index≥start)，则执行步骤S606：选区范围更新完成。在本步骤中，因删除指令对应的索引值大于等于选区的起始索引值小于等于选区的结束索引值(即start≤index≤end)，意味着数据块的删除指令是对选区内的数据块进行的删除指令，因而选区的起始索引值不变而仅结束索引值减一，即选区范围最终变小。
下面进行示例性说明。假设数据块A1有子数据块A2、B2、C2和D2，分别对应索引值数组{0,1,2,3}，若数据块B2和C2为被引用数据块，则选区S的关联数据块为A1，选区S的范围为[1,2]，即选区的起始索引值为1(即start＝1，对应数据块B2)，结束索引值为2(即end＝2，对应数据块C2)。若数据块删除指令的索引值为0(即index＝0)，即该删除指令用于删除数据块A2，因index≤end且index＜start，则选区整体前移，范围更新为[0,1]，分别对应前移后的数据块B2和C2；若数据块删除指令的索引值为1(即index＝1)，即该删除指令用于删除被引用数据块B2，因start≤index≤end，则选区范围更新为[1,1]，对应前移后的数据块C2；若数据块删除指令的索引值为2(即index＝2)，即该删除指令用于删除被引用数据块C2，因start≤index≤end，则选区范围更新为[1,1]，对应未移动的数据块B2；若数据块删除指令的索引值为3(即index＝3)，即该删除指令用于删除数据块D2，因index＞end，则选区的范围无需更新，范围仍为[0,1]。
需要说明是，前述一个或多个实施例中的数据块删除指令是就删除一个数据块而言的，本领域技术人员可以理解，可以通过多个删除指令依次删除多个数据块(例如循环上述步骤S601-S606)、或者通过一个删除指令删除多个数据块等方式实现删除多个数据块，本公开在此不做限制。
参考图7，图7示出了本公开一实施例提供基于目标操作确定选区的范围的方法的流程图，方法700包括步骤S701-步骤S710。
步骤S701：确定对选区的关联数据块的目标操作是否包括数据块插入指令，所述数据块插入指令用于在索引值(index)处插入数据块。示例性地，数据块插入指令可以为指令{p:[path,idx],li:obj}，索引值可以为该指令中“idx”对应的数值。
步骤S702：确定选区的范围是否为空。示例性地，当选区的结束索引值小于起始索引值时，表示选区的范围为空。
若步骤S702确定所述选区为空，则执行步骤S7021：确定所述插入指令所插入的数据块是否为从所述选区的前一个关联数据块中被拖拽的被引用数据块；其中，所述选区的前一个关联数据块为 所述选区的关联数据块更新前的关联数据块。即，在本步骤用于判断所插入的数据块是从之前的选区内拖拽过来的数据块。
若步骤S7021判断为是，则执行步骤S7022：选区的起始索引值为所述索引值(即start＝index)，选区的结束索引值为所述索引值(end＝index)。
若步骤S7021判断为否，则步骤S710：选区范围更新完成。在本例中，若判断为否，则表明当前插入指令所插入的数据块并非被用户从选区的前一个关联数据块中拖拽的被引用的数据块，则无需对选区的范围进行更新。
若步骤S702确定选区的范围不为空，则执行步骤S703：确定所述插入指令所插入的数据块是否为从所述选区的前一个关联数据块中被拖拽的被引用数据块，或者，确定所述数据块插入指令是否为针对引文中的关联数据块。
其中，所述引文为引用所述被引用数据块的在线文档。在一些实施例中，以图2为例进行说明，第一在线文档210的第一数据块10下的子数据块11和12被第二在线文档220引用，第二在线文档即为步骤S703中所述的“引文”，而步骤S703用于确定所述数据块插入指令是否为作用于第二在线文档中的所述被引用数据块所在的父数据块的指令。
若步骤S703的判断结果为是，则执行步骤S704：设左阈值left等于所述选区的起始索引值start(即left＝start)，并设右阈值right等于所述选区的结束索引阈值加一(即right＝end+1)。
若步骤S703的判断结果为否，则执行步骤S705：设左阈值left等于所述选区的起始索引阈值start加1(即left＝start+1)，并设右阈值right等于所述选区的结束索引阈值(即right＝end)。
步骤S706：确定索引值(index)是否小于等于右阈值。
若索引值小于等于右阈值(即index≤right)，则执行步骤S707：选区的结束索引值加1(即end＝end+1)；
若索引值大于右阈值(即index＞right)，则可以跳过其他步骤直接执行步骤S710：选区范围更新完成。在本例中，因索引值大于右阈值，则该插入指令被认为是在选区右端点的右侧插入数据块，则可以无需对选区范围进行更新。
步骤S708：确定索引值是否小于左阈值。
若索引值小于左阈值(即index＜left)，则执行步骤S709：选区的起始索引值加1(即start＝start+1)。在本例中，如果索引值小于左阈值，该插入指令则被认为是在选区左端点的左侧插入数据块，因而选区最终的左右区间值均加相应加1。
若插入指令的索引值大于等于左阈值(即index≥left)，则执行步骤S709：选区的起始索引值加1(即start＝start+1)。在本步骤中，如果索引值大于等于左阈值，则该插入指令被认为是在选区范围内插入数据块，因而最终选区的左区间值不变，右区间值加1。
步骤S710：选区范围更新完成。
根据本公开的一个或多个实施例，通过对于不同类型的数据块插入指令设置不同的左、右阈值，该左、右阈值可以表示“拟制地”选区范围(左右阈值可以分别对应左右区间)，对于针对引文中的关联数据块的插入指令(或者在选区的端点处插入被拖拽的被引用数据块)与针对原文中的插入指令相比，前者对应的左右阈值形成区间范围(即[start,end+1])与后者形成的左右阈值形成的区间范围(即[start+1,end])相比，左右均扩大了一个单位。这样，当用户在引文中在选区的端点处插入数据块(或者在选区的端点处插入被拖拽的被引用数据块)时，被认为是在选区内进行的插入，从而可以相应扩大选区的范围，而当用户在原文中在选区的端点处增加数据块时，该数据块不作为新增的被引用数据块，从而可以实现更符合用户意图的被引用数据块的同步更新。
在一些实施例中，步骤S140包括：
步骤C1：若所述目标操作用于将所述第一数据块下的所述被引用数据块拖拽至与所述第一数据块并列，则创建新数据块作为所述被拖拽的被引用数据块的父数据块；所述新数据块与所述第一数据块的父数据块具有共同的父数据块；
步骤C2：将所述选区的关联数据块更新为所述新数据块；
步骤C3：基于被所述目标操作拖拽至所述新数据块下的被引用数据块的数量，更新所述选区的范围。
参考图8，用户可以通过分栏操作将数据块A1下方的子数据块A2和B2与所述数据块A1并列，从而实现数据块A2和B2与数据块A1分属于不同的两栏。根据本公开的一个或多个实施例，可以创建数据块41作为分栏后的数据块A2和B2的父数据块，数据块41和A1的父数据块42具有共同的父数据块40。若子数据块A2和B2为被引用的数据块，则可以将选区的关联数据块由数据块A1更新为数据块41，并基于数据块41下被引用数据块的数量更新选区的范围。在本例中，选区的范围原为[0,1]，选区更新后范围仍为[0,1]。在一个具体实施方式中，用户可以通过将数据块A2、B2拖拽至其父数据块的左侧或右侧，实现被拖拽的数据块与其原父数据块左右分栏。
根据本公开的一个或多个实施例，提供了一种控制数据块的方法，包括：
步骤B1：确定第一文档中的被引用数据块，所述被引用数据块与第二文档具有引用关系。
步骤B2：响应于所述被引用数据块被执行目标操作，在所述第一文档中变更所述被引用数据块的位置；
步骤B3：响应于在所述第一文档中变更被引用数据块的位置，保持第二文档与所述被引用块的引用关系。
在本实施例中，被引用数据块与第二文档之间的引用关系为第二文档引用了被引用数据块。
在一些实施例中，所述被引用数据块为一个数据块或者一组连续的数据块。
在一些实施例中，所述目标操作包括拖拽操作，该拖拽操作用于移动数据块。示例性地，拖拽操作可以在数据块内移动其子数据块，或者在数据块间移动子数据块，例如，拖拽操作可以在第一数据块中删除一个或多个子数据块，并将该一个或多个子数据块插入至其他的数据块下。
根据发明人调查发现，相关在线文档技术提供的实时引用功能并不完善，容易出现被引用部分丢失的问题。例如当用户在线文档中移动或拖拽被其他在线文档引用的内容时，往往会导致被引用的内容在该其他在线文档中丢失，这是因为一段连续的内容被拖拽往往会被认为是其在原文中被删除。
对此，根据本公开的一个或多个实施例，通过因目标操作变更被引用数据块位置的同时，保持第二文档与所述被引用块的引用关系，从而可以避免数据块与文档的引用关系因数据块的移动而中断。
在一些实施例中，通过选区的关联数据块和选区的范围来描述所述被引用数据块的位置和范围；所述选区的关联数据块为所述被引用数据块的父数据块。
在一些实施例中，步骤B3包括：基于所述目标操作重新确定所述选区的关联数据块和/或范围。
关于选区的设置方式或基于目标操作重新确定所述选区的关联数据块和/或范围的具体实施方式，可以参见上文的描述，此处不再赘述。
相应地，如图9所示，根据本公开的一实施例提供了一种控制数据块的方法，包括：
步骤S920：接收服务器发送的选区更新信息；所述选区更新信息由所述服务器基于以下步骤确定：响应于第一数据块被执行目标操作，确定所述第一数据块是否为选区的关联数据块；响应于确定所述第一数据块为选区的关联数据块，则基于所述目标操作重新确定所述选区的关联数据块和/或范围；基于重新确定的所述选区的关联数据块和/或范围确定选区更新信息；其中，所述选区被组织 成通过选区的关联数据块和选区的范围来描述被引用数据块的位置和范围；所述被引用数据块为被至少一个在线文档引用的数据块；
步骤S940：基于所述选区更新信息对所述选区进行更新。
参见图10，根据本公开一实施例提供了一种控制数据块的方法，包括步骤S1001-步骤S1003：
步骤S1001：确定选区的关联数据块是否发生变更。
若选区的关联数据块发生变更，则执行步骤S1002：基于服务器发送的选区更新信息对所述选区进行更新。示例性地，可以向服务器拉取所述选区更新信息并基于所述选区更新信息对所述选区进行更新。
若选区的关联数据块未发生变更，则执行步骤S1003：基于针对所述关联数据块的目标操作重新确定所述选区的范围，并基于重新确定的选区的范围对选区进行更新。
在一些实施例中，若步骤S1003判断结果为空，则执行步骤S1002，即，当客户端基于目标操作确定选区范围为空时，则直接拉去服务器的选区更新信息以更新选区。
根据本公开的一个或多个实施例，当目标操作未改变选区的关联数据块，意味着目标操作仅仅只是关联数据块内进行编辑，例如插入、删除子数据块等，此时客户端无需完全依赖服务器推送的选区更新信息即可对选区的范围进行更新，从而可以提高同步引用的及时性和一致性。
需要说明的是，对于客户端的实施例而言，由于其基本对应于服务器的实施例，所以相关之处参见方法实施例的部分说明即可，在此不再赘述。
相应地，如图11所示，根据本公开的一实施例提供了一种控制数据块的装置1100，包括：
确定单元1120，用于响应于第一文档中的第一数据块被执行目标操作，确定所述第一数据块是否与第二文档具有引用关系；其中，所述目标操作用于在数据块下插入、删除、移动或替换子数据块；
更新单元1140，用于响应于确定所述第一数据块与第二文档具有引用关系，则基于所述目标操作，更新所述第一文档中至少一个数据块与所述第二文档的引用关系。
在一些实施例中，装置1100还包括：
信息生成单元，用于基于重新确定的所述选区的关联数据块和/或范围确定选区更新信息；
信息发送单元，用于向客户端发送所述选区更新信息，以使客户端能够基于所述选区更新信息对所述选区进行更新。
在一些实施例中，提供了一种控制数据块的装置，包括：
被引用数据块确定单元，用于确定第一文档中的被引用数据块，所述被引用数据块与第二文档具有引用关系；
位置变更单元，用于响应于所述被引用数据块被执行目标操作，在所述第一文档中变更所述被引用数据块的位置；
引用单元，用于响应于在所述第一文档中变更被引用数据块的位置，保持所述第二文档与所述被引用块的引用关系。
相应地，如图12所示，根据本公开的一实施例提供了一种控制数据块的装置1200，包括：
信息接收单元1220，用于接收服务器发送的选区更新信息；所述选区更新信息由所述服务器基于以下步骤确定：响应于第一数据块被执行目标操作，确定所述第一数据块是否为选区的关联数据块；响应于确定所述第一数据块为选区的关联数据块，则基于所述目标操作重新确定所述选区的关联数据块和/或范围；基于重新确定的所述选区的关联数据块和/或范围确定选区更新信息；其中，所述选区被组织成通过选区的关联数据块和选区的范围来描述被引用数据块的位置和范围；所述被引用数据块为被至少一个在线文档引用的数据块；
选区更新单元1240，用于基于所述选区更新信息对所述选区进行更新。
对于装置的实施例而言，由于其基本对应于方法实施例，所以相关之处参见方法实施例的部分说明即可。以上所描述的装置实施例仅仅是示意性的，其中作为分离模块说明的模块可以是或者也可以不是分开的。可以根据实际的需要选择其中的部分或者全部模块来实现本实施例方案的目的。本领域普通技术人员在不付出创造性劳动的情况下，即可以理解并实施。
