There are the pixels of different pixel values in condition one, target area, i.e., there are display elements in target area.Fig. 2 is of the invention real
The one kind first for applying the offer of example one shows the display schematic diagram of content.For example, showing text in target area 11 with reference to Fig. 2
Pixel is different with the pixel value of the pixel of display background, at this point it is possible to by the corresponding display of pixel for showing text
Appearance is determined as the first display content, the corresponding display content of whole pixels can also be determined as the first display content；Situation
Two, the pixel value of each pixel is identical in target area, i.e., display elements are not present in target area.Fig. 3 is implementation of the present invention
The another kind first that example one provides shows the display schematic diagram of content.For example, each pixel is equal in target area 12 with reference to Fig. 3
Display background color, at this point it is possible to which the corresponding display content of whole pixels is determined as the first display content.In general, causing this
The reason of the case where class may be that user deletes element in the target area.
Optionally, it after determining target area, in order to make user's hard objectives region, is set in embodiment, to target area
It is differently shown, for example, the display content in highlighted target area, either, the frame etc. in displaying target region.
S120, reception are directed to the control operation of target area.
Wherein, control operation including destruction operation or reforms operation.
In embodiment, control operation is to the first display content institute operation to be performed.It is logical that user is set in embodiment
The mode executive control operation of touch-control is crossed, the executive control operation by way of keying can also be set in practical application.Specifically
, set in embodiment: the control acts on setting control button, and the setting control button includes: revocation key

It includes revocation key and/or reforms key.Specifically, being confirmed whether to be directed to the mesh in the presence of what is executed after determining target area
Mark the destruction operation in region, and if it exists, then key is reformed in pop-up, otherwise, is not popped up again by key.Meanwhile being confirmed whether exist
Non- destruction operation being revoked, for the target area, and if it exists, then pop up revocation key, otherwise, do not pop up revocation and press
Key.When determining revocation key and reforming key cannot all be ejected, user can be prompted to reselect target area, and continue
Determined whether to pop up control button according to target area.For example, behind user selected target region, control button packet is determined
It includes revocation key and reforms key, at this point, control button 13 is popped up in the top of target area 11, at this point, control with reference to Fig. 2
The key of " return " is shown in key 13 as revocation key, the key for showing " cancellation " is determined as reforming key.
In general, user is when controlling element, intelligent interaction plate will record user operate every time it is corresponding
Command content executes the contents such as timing, instruction attributes and location information, and generates operation note.In general, operation note can be with
It is stored by way of log or record sheet.Each operation for target area can be determined by operation note, into
And determine the content that control button is included.
S130, the second display content is shown in target area.
Wherein, the second display content is that the first display content response is generated in the corresponding instruction of control operation.
Illustratively, it determines that control operates corresponding instruction, and is referred to according to instruction lookup for the target of target area
It enables, and the target instruction target word is executed to the first display content, and then obtain the second display content.Wherein, target instruction target word can be needle
To all instructions of target area, it is also possible to instruct for the part of target area.When target instruction target word is for target area
Part instruction when, determining section split instruction be the newer instruction of execution timing.Target instruction target word is set in embodiment to execute timing
Newest instruction.
For example, control operation is destruction operation, then the instruction generated is cancel an order, further, executing should
Cancel an order to find the non-cancel an order for being directed to target area, and cancels non-cancel an order.At this point, target refers to
Enabling is the non-cancel an order, for example, non-destruction operation is write-in element " A ", then when being cancelled being removed in target area
Pin write-in element " A ", at this point, the display content of target area becomes deleting the second display content of " A ".
Again for example, control operation, which is attached most importance to, operates, then the instruction generated is to reform instruction, further, executes
This reforms instruction, to find the cancel an order for being directed to target area, and reforms to cancel an order.At this point, target instruction target word
For the cancel an order, for example, destruction operation is revocation write-in element " B ", then when being reformed being reformed in target area
It is written element " B ", at this point, the display content of target area becomes being written the second display content of " B ".
It should be noted that after having executed control operation, if determining that target area also meets display control key
Condition can then continue display control key, until user closes the display item that control button is either unsatisfactory for control button
Until part.
The technical solution of the present embodiment, the regional choice operation in selected target region is acted on by receiving, and receives needle
For target area control operation, target area show by first display content response in control operation it is corresponding instruct and
Generate second display content technological means, solve in the prior art user want to except last time operate in addition to its
When its operation is cancelled, it need to be cancelled since operating last time, until cancelling until user it is expected the operation cancelled
Technical problem realizes and is cancelled or reformed operation to the display content under any operation timing, increases modification display content
Flexibility, improve the usage experience of user.
