Background
Currently, every time the input of the user is recorded in the local history of the editor, the editor is generally adopted to redo and undo the previous input record through the operations of ctrl + z/ctrl + shift + z. Since the rich text editor Draft-js opens the local history by default, the specific operation flow is as shown in fig. 1, each time through local or remote input, the current data must be updated through the application program editing interface, and each time a stack pushing operation is performed, the representation content of the latest editor is recorded, and when the representation content needs to be undone, the representation content can be fetched and restored back through the last stack.
In addition, fig. 2a, fig. 2b, and fig. 2c respectively show flowcharts of steps of a process of generating a stack undo, a process of executing a undo, and a process of executing a redo for a local input record and a remote input record in the prior art, and as can be seen from fig. 2a to fig. 2c, because the processing of OT, built-in stack entering, and built-in undo stack implemented by using the Json structure is adopted, after a remote user submits input data, the remote input data also enters the local undo stack, and it is impossible to distinguish whether the local input data or the remote input data, so that the content input by the remote user may be undone by a local undo operation.
In view of the above problems, no effective solution has been proposed.

step S104, executing a second editing operation on the target text through the text editor on the second client, and obtaining a second operation result from the first stack, where the second editing operation includes one of: undo operation and redo operation, where the second operation result is used to indicate the latest changed data content of the target text corresponding to the second client;
step S106, on the second client, removing the second operation result from the first stack and adding the second operation result to a second stack, where the first stack and the second stack respectively correspond to an undo operation and a redo operation based on the operation type of the second editing operation;
step S108, on the second client, performing a conversion operation on the first operation result by using the association relationship between the second operation result added in the second stack and the first operation result obtained by the first editing operation, so as to obtain a third operation result.
In the embodiment of the present disclosure, a first operation result of performing a first editing operation on a target text by a remote client (i.e., a first client) is distributed to a local client (i.e., a second client), and a second editing operation is performed on the target text at the local client, a second operation result is obtained from a first stack, and the second operation result is added to a second stack by removing the second operation result from the first stack at the local client, because the first stack and the second stack correspond to a undo operation and a redo operation, respectively, based on an operation type of the second editing operation; therefore, a conversion operation may be performed on the first operation result by using the association relationship between the second operation result added in the second stack and the first operation result obtained by the first editing operation on the local client, so as to obtain a third operation result.
Therefore, the purposes that the remote client and the local client cannot simultaneously realize online editing and cancel mutual noninterference are achieved, the technical effect that the target text can be subjected to noninterference cancel operation or redo operation through the text editor under the condition of cooperation of multiple clients is achieved, and the technical problems that the remote client and the local client cannot simultaneously realize online editing and one party does not influence the other party when the other party performs redo cancel in the conventional text processing method are solved.
Optionally, the first client is a remote client, the second client is a local client, the text editor is a rich text editor Draft-js, and for the same target text, different user clients may perform editing operations, such as undo operation and redo operation, on the target text by connecting the text editors.
As an alternative embodiment, the rich text editor is a text editor that can be embedded in a browser, so-called what-you-get, and unlike a general text editor, by embedding the rich text editor in a local website or program downloaded over a network, a user can edit text, such as article text or information text, conveniently.
Optionally, the first editing operation includes one of: and canceling operation and redoing operation, wherein the first operation result is used for indicating the latest changed data content of the target text corresponding to the remote client.
In an optional embodiment, taking the first client as a remote client and the second client as a local client as an example, a first editing operation is performed on a target text on the remote client through a text editor to obtain a first operation result, and the first operation result is distributed to the local client; and executing a second editing operation on the target text through the text editor on the local client, and acquiring a second operation result from the first stack, where the second operation result is used to indicate the latest changed data content of the target text corresponding to the second client.
As an alternative embodiment, the first stack and the second stack respectively correspond to an undo operation and a redo operation based on the operation type of the second editing operation; for example, when the second editing operation is a undo operation, the first stack corresponds to an undo operation, and the second stack corresponds to a redo operation; when the second editing operation is a redo operation, the first stack corresponds to a redo operation and the second stack corresponds to an undo operation.
As an alternative embodiment, the first stack is a redo stack, and is used for storing the first operation result and the second operation result, and when the redo operation is performed, the conversion operation can be properly executed to restore to a correct local operation; the second stack is an undo stack, and the contents of the undo stack and the redo stack are the same, but the operation type based on the second editing operation is transferred between the two stacks.
As an alternative embodiment, the association relationship between the second operation result and the first operation result is determined by using the remote operation identifier of the first operation result and the conversion operation identifier of the first stack.
Optionally, by marking the first operation result with the remote operation identifier and marking the first stack with the conversion operation identifier, and the second operation result is obtained from the first stack, the association relationship between the first operation result and the second operation result may be determined.
As an optional embodiment, it is determined whether the current operation on the target text is the operation of the remote client or the operation of the local client by monitoring a first operation result of the local client on the target text through the text editor or monitoring whether a second operation result pushed by the remote client to the local client is received, for example, when the second operation result of the local client is removed from the undo stack, the second operation result is added to the redo stack, and then the local client performs a conversion operation on the first operation result by using an association relationship between the second operation result added to the redo stack and the first operation result of the remote client to obtain a third operation result, which can ensure that the local undo operation does not undo the current editing operation of the remote client And stacking, and performing conversion operation on the first operation result by the local client by using the association relationship between the second operation result added in the revocation stack and the first operation result of the remote client to obtain a third operation result, so that the local redo operation can be prevented from being affected by the current editing operation of the remote client.
For example, a plurality of user clients edit simultaneously, and both the remote user a and the local user B edit the target text at the same time, but the remote user a can only redo and undo the text content input by itself, and the first operation result is distributed to the local client B through the shared database, and the redo operation or undo operation cannot be performed on the second operation result of the local client B.
As an alternative embodiment, the method further includes: and the second client sends the third operation result to the first client.
As an alternative embodiment, performing a conversion operation on the first operation result by using the association relationship between the second operation result and the first operation result, and obtaining the third operation result includes:
step S202, obtaining a first identifier, a second identifier, a third identifier and data to be edited in the second operation result on the second client, and obtaining text content corresponding to the first operation result;
step S204, determining, on the second client, the first identifier, the third identifier, and the data to be edited in the third operation result by using the first identifier, the third identifier, and the data to be edited in the second operation result, and determining, on the basis of the second identifier in the second operation result and the text content corresponding to the first operation result, the second identifier in the third operation result.
As an alternative embodiment, the data storage structure of the text editor may include, but is not limited to: setting the maximum local storage stack length to prevent excessive memory overflow of the stack; distinguishing the editing operation of a local client side from the editing operation of a remote client side by recording the identity identification number of the current historical record and the identity identification number of the next pushed historical record; moreover, an operation conversion key required by conversion operation can be set, wherein each of the undo stack and the redo stack corresponds to a unique conversion operation key.
As an alternative embodiment, determining the second identifier in the third operation result based on the second identifier in the second operation result and the text content corresponding to the first operation result includes:
step S302, determining the display position of the data to be edited in the text content corresponding to the first operation result;
step S304, performing a shift operation on the second identifier in the second operation result based on the display position to obtain the second identifier in the third operation result.
As an alternative embodiment, for example, the description information of the first operation result remoteOp and the second operation result localOp may be: https:// github. com/ottypes/json0, for describing a set of operations, such as [ { p: [ 'a', 0], ld:100} ], at index 0 on path a, delete 100 this element; the third operation result newOp is obtained by shifting the second identifier of the second operation result through the display position in the text content corresponding to the first operation result remoteOp, for example, the character on the current a is abcd, the second operation result localOp [ { p: [ 'a', 2], li:100} ], the third operation result obtained by conversion is ab100cd, the first operation result remoteOp [ { p: [ 'a', 2], ld: b } ], a100cd, and the second operation result localOp is directly adopted by rolling back the local operation, which may cause a problem, and the third operation result newOp [: [ { p: [ 'a', 1} ] may be obtained after the conversion processing.
As an alternative embodiment, the method further includes:
step S402, obtaining a first text state and a second text state on the second client, wherein the first text state is used for describing the latest input data content through the text editor, and the second text state is used for describing the last input data content through the text editor;
step S404, determining the latest changed data content based on the first text status and the second text status on the second client, and obtaining the second operation result.
In the embodiment of the present disclosure, based on the collaborative text editing logic of the rich text editor Draft-js, the granularity of a single operation on the rich text editor each time may be obtained by calculating a text state difference value according to the latest input data content and the last input data content of the text editor, for example, the latest change data content may be determined by calculating a text state difference value between text states determined by data contents of any two input operations.
As an alternative embodiment, in order to more accurately calculate a text state difference value between the latest input data content and the last input data content of the rich text editor, after waiting for a preset time period, calculation of the latest input data content and the last input data content may be started again, and the latest changed data content may be determined to obtain the second operation result.
As an alternative embodiment, as shown in fig. 4, when receiving input content of a remote client, triggering a remote callback event, and distributing the first operation result to a local client; when receiving the input content of the local client, triggering a local callback event to execute a stack pushing operation, namely executing a second editing operation on the target text on the second client through the text editor, acquiring a second operation result from the first stack, removing the second operation result from the first stack and adding the second operation result to the second stack on the second client.
As an alternative embodiment, the method further includes:
step S502, when the second editing operation is a undo operation, determining whether an anti-shake function is started on the second client, wherein the anti-shake function is used for controlling the processing times of the undo operation within a preset time length;
step S504, when the anti-shake function is not activated on the second client, determining to remove the second operation result from the first stack, add the second operation result to the second stack, and perform a conversion operation on the first operation result by using the association relationship between the second operation result and the first operation result to obtain the third operation result;
step S506, when the anti-shake function is activated on the second client, ignoring the second editing operation and deactivating the anti-shake function.
As shown in fig. 4, by turning on the anti-shake function, the local computation consumption of the rich text editor can be reduced based on the anti-shake logic by controlling the processing times of the undo operation within a preset time period. When the anti-shake function is not started on the second client, determining to remove the second operation result from the first stack, adding the second operation result to the second stack, and performing a conversion operation on the first operation result by using the association relationship between the second operation result and the first operation result to obtain the third operation result.
And when the anti-shake function is started on the second client, ignoring the second editing operation, closing the anti-shake function, detecting whether the time limit for text submission is reached, if so, calculating a text state difference value between the latest input data content and the last input data content of the rich text editor, and submitting the state difference value to the server.
In the disclosed embodiment, since the result of the calculation operation needs to consume a large amount of local calculation power, anti-shake logic is added for, for example, no longer inputting within 1 second after inputting, i.e., turning off and submitting, and ignoring if inputting is still in process.
As an alternative embodiment, the description information of the first operation result and the second operation result includes: a first component for determining a target position to be edited in the target text, and a second component for determining text data to be edited at the target position;
the first component includes: a first identifier and a second identifier, wherein the first identifier is used for determining a starting position of a character string to be edited in the target text, and the second identifier is used for indexing the target position in the character string to be edited according to the starting position;
the second component includes: the third identifier is used for determining an editing operation type to be executed at the target position, and the data to be edited is operation data corresponding to the editing operation type.
