通过上述附图，已示出本公开明确的实施例，后文中将有更详细的描述。这些附图和文字描述并不是为了通过任何方式限制本公开构思的范围，而是通过参考特定实施例为本领域技术人员说明本公开的概念。
具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的设备和方法的例子。
图1是根据一示例性实施例示出的一种网页调整方法的流程图，如图1所示，该网页调整方法可以用于在电子设备中对当前显示的网页进行调整。该电子设备可以是智能手机、平板电脑或者电子书阅读器等。该网页调整方法可以包括以下步骤：
在步骤102中，接收网页调整指令，该网页调整指令为检测到对当前显示的网页的触控操作时生成的指令，该网页调整指令中包含有至少一个触控点坐标；
在步骤104中，根据该至少一个触控点坐标和该网页的DOM(Document Object Model，文件对象模型)树从该网页的各个内容节点中确定目标内容节点；
在步骤106中，将该目标内容节点对应的显示区域的中心调整至屏幕的中心。
综上所述，本示例性实施例示出的网页调整方法，通过接收包含有至少一个触控点坐标的网页调整指令，根据该至少一个触控点坐标和该网页的文件对象模型DOM树从该网页的各个内容节点中确定目标内容节点，并将该目标内容节点对应的显示区域的中心调整至屏幕的中心，只需要用户一次操作就可以将对应的内容节点的显示区域移动至适合用户浏览的屏幕中心位置，解决了相关技术中若要将网页中的某一块内容调整至适合浏览的位置，通常需要用户经过多次调整操作的问题，达到简化用户操作，节约用户时间的效果。
图2是根据另一示例性实施例示出的一种网页调整方法的流程图，如图2所示，该网页调整方法可以用于在电子设备中对当前显示的网页进行调整。该电子设备可以是智能手机、平板电脑或者电子书阅读器等。该网页调整方法可以包括以下步骤：
在步骤202中，接收网页调整指令，该网页调整指令中包含有至少一个触控点坐标；
网页调整指令为检测到对用户当前显示的网页的触控操作时生成的指令。其中，用户对当前显示的网页的触控操作可以是点击操作或者滑动操作。比如，若用户操作为点击操作，该网页调整指令中包含有用户点击位置的触控点坐标；若用户操作为滑动操作，且滑动轨迹为一个闭合曲线，则该网页调整指令中包含有该闭合曲线所经过的各个触控点坐标。
在步骤204中，当该至少一个触控点坐标中包含一个触控点坐标时，根据该网页的DOM树确定第一候选节点集合，该第一候选节点集合中包含有该触控点坐标所在的各个内容节点；
网页显示在屏幕中时，该网页的DOM树中的每个可视化内容节点都可以对应在屏幕中的某一块矩形显示区域。在这些可视化内容节点中，某些大节点可能包含一层或多层小节点，对应在屏幕中即显示为大的矩形显示区域包含一层或多层小的矩形显示区域。
以电子设备为智能手机为例，请参考图3所示的一种用户操作示意图，其中，当前网页中显示有4个一级可视化内容节点，分别对应图3中的四块矩形区域A、B、C和D；B区域对应的一级可视化内容节点中又包含有一个二级可视化内容节点，对应图3中的矩形区域B1；B1区域对应的二级可视化内容节点中又包含有三个三级可视化内容节点，对应图3中的矩形区域B11、B12和B13。
用户在对该网页进行点击操作时，生成的网页调整指令包含有该用户点击位置的触控点坐标，智能手机根据该触控点坐标和网页的DOM树确定该触控点坐标处于B13区域内，则包含触控点坐标的区域有B、B1和B13；智能手机确定第一候选节点集合为区域B、B1和B13对应的内容节点组成的集合。
在步骤206中，将该第一候选节点集合中，显示宽度小于屏幕宽度且显示面积最大的内容节点确定为目标内容节点；
以图3为例，区域B的宽度与屏幕宽度相同，则第一候选节点集合中区域B1和B13对应的内容节点的显示宽度小于屏幕宽度，而区域B1的面积大于区域B13，因此，智能手机选择区域B1对应的内容节点为目标内容节点。
在步骤208中，当该至少一个触控点坐标为一段闭合曲线的坐标时，根据该网页的DOM树确定第二候选节点集合，该第二候选节点集合中包含有与该闭合曲线所围区域的相交面积占该闭合曲线所围面积的比例大于预定比例阈值的内容节点；
其中，该预定比例阈值可以是开发人员预先设置的比例阈值，比如50％、70％或者80％等，本示例性实施例对该预定比例阈值的数值不做限定。
以电子设备为智能手机，该预设比例阈值为50％为例，请参考图4所示的另一种用户操作示意图，其中，在初始时刻，智能手机在屏幕中显示整个网页的所有可视化内容节点，各个节点对应的显示区域如图4所示。用户在对该网页进行滑动操作时，滑动轨迹为一个闭合曲线，则生成的网页调整指令包含有该用户滑动轨迹上的各个触控点坐标，智能手机根据该滑动轨迹上的各个触控点坐标和网页的DOM树确定该各个触控点坐标围成的闭合曲线所覆盖到的显示区域有除区域A之外的所有区域，其中，与该闭合曲线所围区域的相 交面积占该闭合曲线所围面积的比例大于50％的显示区域有区域B和B1，智能手机将区域B和B1对应的内容节点组成的集合确定为第二候选节点集合。
在步骤210中，将该第二候选节点集合中显示面积最小的内容节点确定为该目标内容节点；
以图4为例，由于区域B1的面积小于区域B的面积，因此，智能手机将区域B1对应的内容节点确定为目标内容节点。
在步骤212中，当该至少一个触控点坐标为一段闭合曲线的坐标时，根据该网页的DOM树确定第三候选节点集合，该第三候选节点集合中包含有与该闭合曲线所围区域的相交面积占显示面积的比例最大的内容节点；
以电子设备为智能手机为例，请参考图5所示的另一种用户操作示意图，其中，在初始时刻，智能手机在屏幕中显示整个网页的所有可视化内容节点，各个节点对应的显示区域如图5所示。用户在对该网页进行滑动操作时，滑动轨迹为一个闭合曲线，则生成的网页调整指令包含有该用户滑动轨迹上的各个触控点坐标，智能手机根据该滑动轨迹上的各个触控点坐标和网页的DOM树确定该各个触控点坐标围成的闭合曲线所覆盖到的显示区域有除区域A之外的所有区域，其中，与该闭合曲线所围区域的相交面积占显示面积的比例最大的内容节点有3个，分别区域B11、B12和B13对应的内容节点，其比例均为100％，则智能手机将区域B11、B12和B13对应的内容节点组成的集合确定为第三候选节点集合。
在步骤214中，将该第三候选节点集合中显示面积最大的内容节点确定为该目标内容节点；
以图5为例，其中区域B13的面积大于区域B11和B12的面积，因此，智能手机将区域B13对应的内容节点确定为目标内容节点。
在步骤216中，根据该目标内容节点对应的显示区域的当前尺寸和该屏幕的尺寸计算缩放比例，并根据该缩放比例对该网页进行缩放。
其中，电子设备可以预先设置该目标内容节点缩放后的显示区域占整个屏幕的最佳比例，比如，设置该目标内容节点缩放后的显示区域的宽度占屏幕宽度的最佳比例或者设置该目标内容节点缩放后的显示区域的高度占屏幕高度的最佳比例，该最佳比例可以是80％、100％、120％或者其它数值，对此，本示例性实施例不做限定。
以设置该目标内容节点缩放后的显示区域的宽度占屏幕宽度的最佳比例为100％为例，假设该目标内容节点对应的显示区域的当前宽度为5，而屏幕宽度为10，则缩放比例为+100％(即放大100％)，若显示区域的当前宽度为20，而屏幕宽度为10，则缩放比例为-50％(即缩小50％)。
以图3至图5任一所示的用户操作示意图中所示的网页为例，假设智能手机通过步骤204～206或者步骤208～210或者步骤212～214任一所示的方法确定区域B1对应的可视化内容节点为目标内容节点，则将区域B1的中心调整至屏幕中心，同时按照计算出的缩放比例将区域B1的宽度调整为屏幕的宽度，调整后的网页示意图如图6所示。
综上所述，本示例性实施例示出的网页调整方法，通过接收包含有至少一个触控点坐标的网页调整指令，根据该至少一个触控点和该网页的文件对象模型DOM树从该网页的各个内容节点中确定目标内容节点，并将该目标内容节点对应的显示区域的中心调整至屏幕的中心，只需要用户一次操作就可以将对应的内容节点的显示区域移动至适合用户浏览的屏幕中心位置，解决了相关技术中若要将网页中的某一块内容调整至适合浏览的位置，通常需要用户经过多次调整操作的问题，达到简化用户操作，节约用户时间的效果。
其次，本示例性实施例提供的网页调整方法，通过根据该目标内容节点对应的显示区域的当前尺寸和该屏幕的尺寸计算缩放比例，并根据该缩放比例对该网页进行缩放，将目标内容节点对应的显示区域调整至更佳的浏览尺寸，从而进一步提高用户体验，简化用户操作。
图7是根据又一示例性实施例示出的一种网页调整方法的流程图，如图7所示，该网页调整方法可以用于在电子设备中对当前显示的网页进行调整。该电子设备可以是智能手机、平板电脑或者电子书阅读器等。该网页调整方法可以包括以下步骤：
在步骤302中，检测当前显示的网页中的纯文本节点内的字符的平均显示面积是否小于预设的面积阈值；
对网页进行缩放和移动时，需要占用一定的处理资源，并消耗一定的电量，而在实际应用中，并不是所有的网页在便携式电子设备中显示时都需要进行缩放或者移动，为了节约电子设备的处理资源和电量，可以只对需要进行调整的网页进行网页调整指令的响应。即检测当前显示的网页中的纯文本节点内的字符的平均显示面积是否小于预设的面积阈值，若小于，则该网页的字符在默认状态下显示面积较小，需要进行调整，否则，可以不进行调整。
其中，该面积阈值可以是一个固定值，也可以根据电子设备的屏幕的分辨率和尺寸进行确定。比如，开发人员可以通过人工标注的方式确定网络中不需要进行调整的网页的集合，并计算集合中的各个网页中的纯文本节点内的字符的平均显示面积s1，在显示网页时，电子设备首先获取当前网页的纯文本节点内的字符的平均显示面积s2，并判断s2＜k*s1是否成立，其中，k为可以是开发人员预先设置的比例参数，也可以是根据电子设备的屏幕的分辨率和尺寸确定的比例参数，对此，本示例性实施例不做限定。
在步骤304中，若当前显示的网页中的纯文本节点内的字符的平均显示面积小于预设的面积阈值，则接收网页调整指令，该网页调整指令中包含有至少一个触控点坐标；
网页调整指令为检测到对用户当前显示的网页的触控操作时生成的指令。其中，用户对当前显示的网页的触控操作可以是点击操作或者滑动操作。比如，若用户操作为点击操作，该网页调整指令中包含有用户点击位置的触控点坐标；若用户操作为滑动操作，且滑动轨迹为一个闭合曲线，则该网页调整指令中包含有该闭合曲线所经过的各个触控点坐标。
在步骤306中，当该至少一个触控点坐标中包含一个触控点坐标时，根据该网页的DOM树确定第一候选节点集合，该第一候选节点集合中包含有该触控点坐标所在的各个内容节点；
网页显示在屏幕中时，该网页的DOM树中的每个可视化内容节点都可以对应在屏幕中的某一块矩形显示区域。在这些可视化内容节点中，某些大节点可能包含一层或多层小节点，对应在屏幕中即显示为大的矩形显示区域包含一层或多层小的矩形显示区域。
以电子设备为智能手机为例，请参考图3所示的一种用户操作示意图，其中，当前网页中显示有4个一级可视化内容节点，分别对应图3中的四块矩形区域A、B、C和D；B区域对应的一级可视化内容节点中又包含有一个二级可视化内容节点，对应图3中的矩形区域B1；B1区域对应的二级可视化内容节点中又包含有三个三级可视化内容节点，对应图3中的矩形区域B11、B12和B13。用户在对该网页进行点击操作时，生成的网页调整指令包含有该用户点击位置的触控点坐标，智能手机根据该触控点坐标和网页的DOM树确定该触控点坐标处于B13区域内，则包含触控点坐标的区域有B、B1和B13；智能手机确定第一候选节点集合为区域B、B1和B13对应的内容节点组成的集合。
在步骤308中，将该第一候选节点集合中，显示宽度小于屏幕宽度且显示面积最大的内容节点确定为目标内容节点；
以图3为例，区域B的宽度与屏幕宽度相同，则第一候选节点集合中区域B1和B13对应的内容节点的显示宽度小于屏幕宽度，而区域B1的面积大于区域B13，因此，智能手机选择区域B1对应的内容节点为目标内容节点。
在步骤310中，当该至少一个触控点坐标为一段闭合曲线的坐标时，根据该网页的DOM树确定第二候选节点集合，该第二候选节点集合中包含有与该闭合曲线所围区域的相交面积占该闭合曲线所围面积的比例大于预定比例阈值的内容节点；
其中，该预定比例阈值可以是开发人员预先设置的比例阈值，比如50％、70％或者80％等，本示例性实施例对该预定比例阈值的数值不做限定。
以电子设备为智能手机，该预设比例阈值为50％为例，请参考图4所示的另一种用户 操作示意图，其中，在初始时刻，智能手机在屏幕中显示整个网页的所有可视化内容节点，各个节点对应的显示区域如图4所示。用户在对该网页进行滑动操作时，滑动轨迹为一个闭合曲线，则生成的网页调整指令包含有该用户滑动轨迹上的各个触控点坐标，智能手机根据该滑动轨迹上的各个触控点坐标和网页的DOM树确定该各个触控点坐标围成的闭合曲线所覆盖到的显示区域有除区域A之外的所有区域，其中，与该闭合曲线所围区域的相交面积占该闭合曲线所围面积的比例大于50％的显示区域有区域B和B1，智能手机将区域B和B1对应的内容节点组成的集合确定为第二候选节点集合。
在步骤312中，将该第二候选节点集合中显示面积最小的内容节点确定为该目标内容节点；
以图4为例，由于区域B1的面积小于区域B的面积，因此，智能手机将区域B1对应的内容节点确定为目标内容节点。
在步骤314中，当该至少一个触控点坐标为一段闭合曲线的坐标时，根据该网页的DOM树确定第三候选节点集合，该第三候选节点集合中包含有与该闭合曲线所围区域的相交面积占显示面积的比例最大的内容节点；
以电子设备为智能手机，请参考图5所示的另一种用户操作示意图，其中，在初始时刻，智能手机在屏幕中显示整个网页的所有可视化内容节点，各个节点对应的显示区域如图5所示。用户在对该网页进行滑动操作时，滑动轨迹为一个闭合曲线，则生成的网页调整指令包含有该用户滑动轨迹上的各个触控点坐标，智能手机根据该滑动轨迹上的各个触控点坐标和网页的DOM树确定该各个触控点坐标围成的闭合曲线所覆盖到的显示区域有除区域A之外的所有区域，其中，与该闭合曲线所围区域的相交面积占显示面积的比例最大的内容节点有3个，分别区域B11、B12和B13对应的内容节点，其比例均为100％，则智能手机将区域B11、B12和B13对应的内容节点组成的集合确定为第三候选节点集合。
在步骤316中，将该第三候选节点集合中显示面积最大的内容节点确定为该目标内容节点；
以图5为例，其中区域B13的面积大于区域B11和B12的面积，因此，智能手机将区域B13对应的内容节点确定为目标内容节点。
在步骤318中，根据该目标内容节点对应的显示区域的当前尺寸和该屏幕的尺寸计算缩放比例，并根据该缩放比例对该网页进行缩放。
其中，电子设备可以预先设置该目标内容节点缩放后的显示区域占整个屏幕的最佳比例，比如，设置该目标内容节点缩放后的显示区域的宽度占屏幕宽度的最佳比例或者设置该目标内容节点缩放后的显示区域的高度占屏幕高度的最佳比例，该最佳比例可以是80％、 100％、120％或者其它数值，对此，本示例性实施例不做限定。
以设置该目标内容节点缩放后的显示区域的宽度占屏幕宽度的最佳比例为100％为例，假设该目标内容节点对应的显示区域的当前宽度为5，而屏幕宽度为10，则缩放比例为+100％(即放大100％)，若显示区域的当前宽度为20，而屏幕宽度为10，则缩放比例为-50％(即缩小50％)。
以图3至图5任一所示的用户操作示意图中所示的网页为例，假设智能手机通过步骤306～308或者步骤310～312或者步骤314～316任一所示的方法确定区域B1对应的可视化内容节点为目标内容节点，则将区域B1的中心调整至屏幕中心，同时按照计算出的缩放比例将区域B1的宽度调整为屏幕的宽度，调整后的网页如图6所示。
综上所述，本示例性实施例示出的网页调整方法，通过接收包含有至少一个触控点坐标的网页调整指令，根据该至少一个触控点和该网页的文件对象模型DOM树从该网页的各个内容节点中确定目标内容节点，并将该目标内容节点对应的显示区域的中心调整至屏幕的中心，只需要用户一次操作就可以将对应的内容节点的显示区域移动至适合用户浏览的屏幕中心位置，解决了相关技术中若要将网页中的某一块内容调整至适合浏览的位置，通常需要用户经过多次调整操作的问题，达到简化用户操作，节约用户时间的效果。
其次，本示例性实施例提供的网页调整方法，通过根据该目标内容节点对应的显示区域的当前尺寸和该屏幕的尺寸计算缩放比例，并根据该缩放比例对该网页进行缩放，将目标内容节点对应的显示区域调整至更佳的浏览尺寸，从而进一步提高用户体验，简化用户操作。
