Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are some of the embodiments of the present invention, instead of all the embodiments.Based on this hair
Embodiment in bright, every other implementation obtained by those of ordinary skill in the art without making creative efforts
Example, shall fall within the protection scope of the present invention.
Shown in Figure 1, the embodiment of the invention provides a kind of, and method is revised in the tracking based on browser, comprising:
Step 100: status indication being carried out to the initial content data in the rich text input frame of browser, is obtained corresponding first
The first state sequence of beginning content-data；
Optionally, state includes original state, input state and deletion state in the present embodiment.
Status indication is carried out firstly the need of to initial content data in this step, and records obtained first state sequence.
Such as: initial content data are one section of content of text, using each character as a minimum unit, to each character cell into
Row original state label.In data labeling process, each element records current state, and state can be divided into 1,0, -1 three kind, and 1 represents
The element is that user newly inputs, and 0 to represent the element be the element in the initial content of user, and -1 represent will in user's input process
The element is deleted.So each elementary state of initial content data markers is 0, the following are primary data flag states, and will
Flag state storage.Case text initial content are as follows: abcdefg.
| a | b | c | d | e | f | g |
| 0 | 0 | 0 | 0 | 0 | 0 | 0 |
Step 200: original state being carried out to current content data in edited RichTextBox using first state sequence
Label；
In this step, after edit operation occurs for user, the content change event of rich text input frame is triggered, is obtained current
Content-data, and initial markers are executed, present case is that user deletes " c " behind second character and inputs new character " x ",
And the edited current content data of current input frame is obtained and first state sequence is utilized to generate default label state:
| a | b | x | d | e | f | g |
| 0 | 0 | 0 | 0 | 0 | 0 | 0 |
Step 300: comparing initial content data and current content data obtains content change record information；
Compare initial content data in this step and user's input content pre-post difference mutation is calculated in current content data
Change, the modification for calculating user is to belong to a kind of that aforementioned situation, is determined after calculating, and the c in initial one is to be deleted
The character content removed, currently inputting x in newest content is the newly added character content of user.
Step 400: information being recorded according to content change and is revised the content feed of variation into initial content data
Content-data, and the second status switch is obtained to the state after the variation of first state sequence mark；
In this step, 1 character x is increased after the 3rd character on initial text content basis, by x character pair
The status indication new state answered, when marking newly-increased character mode, the character newly increased exists in original text without corresponding
, so being uniformly revised as state 1, indicates newly-increased state, the second status switch can be obtained.
| a | b | c | x | d | e | f | g |
| 0 | 0 | -1 | 1 | 0 | 0 | 0 | 0 |
Step 500: rendering being carried out to the content of variation and is shown.
The content of variation is rendered in this step, binding marker shows different pattern, if the content newly increased,
It will show that green text band underscore is then displayed in red in text band and crosses if it is content is deleted.
The tracking revision method based on browser of the embodiment of the present invention is first in the rich text input frame of browser
Initial content data carry out status indication, obtain the first state sequence of corresponding initial content data, utilize first state later
Sequence carries out original state label to current content data in edited RichTextBox, then compares initial content data and current
Content-data obtains content change record information, to record information for the content feed of variation to initial interior according to content change
Hold and obtain Description of Revision data in data, and the second status switch is obtained to the state after the variation of first state sequence mark, most
Rendering is carried out to the content of variation afterwards to show, completes tracking revision process, and then solve the stage and execute text in Web browser
The problem of this editor task is without revision function.
In some embodiments, as shown in Fig. 2, using first state sequence to current in edited rich text input frame
Content-data carry out original state label step 200 include:
Step 201: receiving the content change event command of rich text input frame；
Step 202: obtaining current content data in edited rich text input frame；
Step 203: original state label being carried out to current content data using first state sequence.
Step 200 in the present embodiment specifically: after edit operation occurs for user, receive the content change thing of triggering input frame
Part instruction, obtains current content data in rich text input frame later, by the minimum unit element extraction in input frame and by suitable
Sequence forms a new text sequence.If picture occurs in input frame, a picture is considered as a common language, identification is every
A picture is uniquely numbered and status indication etc..Default conditions are marked to the character nodes obtained after editor, user is to initial interior
Hold data to start to edit, there are three types of the primary operations edited to initial content only of user:
A. segment word is newly increased；
B. segment word is deleted；
C. increase text simultaneously and delete segment word (when user chooses certain section of text and pastes the classes such as other new texts
Like replacement operation) for the third replacement operation, agreement: replacement operation can be analyzed to once delete text operation+primary increase
Text operation.
Later and initial markers are executed, present case is that user deletes " c " behind second character and inputs new character
" x ", and the edited text of current input frame is obtained and generates default label state.
In some embodiments, content change note is obtained with current content data as shown in figure 3, comparing initial content data
Record information step 300 include:
Step 301: utilizing the front and back head and the tail content of way of contrast acquisition content change position and variation one by one；
Step 302: revision type is determined according to the content of variation；
Wherein, content change record information includes the content and revision type of content change position, variation.
Step 300 in the present embodiment specifically: the change of divergence before and after user's input content is calculated, from
And determine that the modification of user is to belong to a kind of that aforementioned situation.
Because edit operation cannot operate two discontinuous segment texts simultaneously, difference calculation takes front and back
Head and the tail way of contrast one by one, the character string of editor front and back below:
| a | b | C | d | e | f | g |
| a | b | x | d | e | f | G |
Subordinate clause head beginning character a first starts, and compares one by one, and a is identical, and b is identical, until c is not identical as x, intercepts at this time
And previous section character string ab (part as before indicates new and old sentence part not to be edited) is stored, and record present bit
Set 2.
Remaining character content:
| C | d | e | f | g |
| x | d | e | f | G |
After intercepting stem identical characters content, backward is carried out to remaining character and is compared one by one
Inverted order compares since character g, and g, f, e, d is identical, until c is different from x, intercepts at this time and stores aft section word
Symbol string defg (aft section is identical to indicate new and old sentence tail portion part not to be edited)
Remaining character content:
| C |
| x |
It is determined after calculating, the c in initial one is deleted character content, is currently inputted in newest content
X be the newly added character content of user, final definitive result:
A. 1 character c is deleted after the 2nd character on initial text content basis；
B. 1 character x is increased after the 2nd character on initial text content basis；
C. since tracking revision is to maintain user's modification record, so increasing the physical location of character, before needing to be calculated as
The length of the length of face identical characters and deleted character, i.e., in the 3rd (length 1 that the length 2 of character ab adds character c) a word
Increase character x after symbol.
Obtain difference calculation result data:
In some embodiments, information is recorded according to content change to obtain the content feed of variation into initial content data
To Description of Revision data, and the step 400 for obtaining the second status switch to the state after the variation of first state sequence mark includes:
If the content of variation is to delete character, more by the state of the position for deleting character bit corresponding in first state sequence
It is newly deletion state；
If the content of variation is newly-increased character, inputted being inserted at the position of newly-increased character corresponding in first state sequence
State.
The step 400 of the present embodiment is specifically as follows: a. is deleted after the 2nd character on initial text content basis
After 1 character c, by the corresponding status indication new state of c character, when label deletes character, it then follows regular once:
If original state is -1, it has been deletion state before indicating, has then still been set as -1；
If original state is 0, it is normal state text before indicating, sets -1 for state；
It is the text of addition if original state is 1, before indicating, setting 2 for state, (special state is indicated more
In step after new state, the character can be really kicked out of, it, then can be straight because increased character is deleted again under tracking revision mode
Connect deletion).
| a | b | c | d | e | f | g |
| 0 | 0 | -1 | 0 | 0 | 0 | 0 |
B. 1 character x is increased after the 3rd character on initial text content basis, by the corresponding state of x character
Mark new state, when marking newly-increased character mode, the character newly increased in original text without existing for corresponding, so system
One is revised as state 1, indicates newly-increased state.
| a | b | c | x | d | e | f | g |
| 0 | 0 | -1 | 1 | 0 | 0 | 0 | 0 |
C. in the character content after the completion of state being applied, if be marked as 2 special state, it executes filtering and kicks
Out.
In some embodiments, as shown in figure 4, to the content of variation carry out rendering display step 500 after further include:
Step 600: storage Description of Revision data and the second status switch, using Description of Revision data as next edit operation
Initial content data；
Step 700: storage current content data into historical record, and record current state and show be in historical record most
Latter item record.
The tracking revision method based on browser of the embodiment of the present invention also needs storage Description of Revision data and the second state
Sequence, using Description of Revision data as the initial content data of next edit operation.
At this point for the calculating in period next time, original text is are as follows:
| a | b | c | x | d | e | f | g |
| 0 | 0 | -1 | 1 | 0 | 0 | 0 | 0 |
By current content data storage into historical record, and records current state and show it is the last item in historical record
Record checks whether content shown by current data is the last one in historical record,
A. if it is, newest data are added in record；
B. if it is not, then the subsequent record in the position is all deleted, and add it is current it is newest be recorded as it is newest
The last one.
It can be with after realizing tracking revision in addition, tracking revision rollback forward operation can also be carried out in the present embodiment
According to the historical record of each modification storage, allow to retract and advance, the history stored in editing process in the present embodiment
Record:
Under normal state, text status is the last one in historical record, remembers text frame current display data pair
Should be in the position in historical record, such as the current historical record of this example there are 2, the rearmost position of record is 2.
When selection is executed and retracted, whether there is historical record before checking current location, if there is then by previous record
It takes out and shows and be rendered into Text Entry, this example so taking out the 1st article of record, and records current location currently at the 2nd article
It is 1.
When selection executes advance, check after current location there is historical record, if there is then taking out display, this example is being executed
After one step retracts, the position of current record is 1, is rendered into Text Entry so taking out subsequent 2nd article of display, and record
Position is 2.
The tracking revision method based on browser of the embodiment of the present invention can choose reception revision or be refused after revision
Revision absolutely.Receiving revision is the data content that will have currently edited, and according to mark information, calculates new content, is formatted as
Plain text, i.e. newly-increased text do not show that newly-increased label, the text of deletion are not then displayed in text, so by current data
In text status, state is that 1 to re-flag be 0, and state is -1 and re-flags as 2 (special states), the common word that state is 0
It accords with constant.
It is specifically as follows in this example:
| a | b | c | x | d | e | f | g |
| 0 | 0 | -1 | 1 | 0 | 0 | 0 | 0 |
After re-flagging
| a | b | c | x | d | e | f | g |
| 0 | 0 | 2 | 1 | 0 | 0 | 0 | 0 |
In character content after the completion of state is applied, if be marked as 2 special state, it executes filtering and kicks out of,
Obtain result:
| a | b | x | d | e | f | g |
| 0 | 0 | 0 | 0 | 0 | 0 | 0 |
The data render of newest only normal state label is shown in text box.
The effect that editor generates is cancelled in refusal revision, all edit effects is reduced to initial one, note will delete
Text character add back, newly-increased text character is deleted, so by text status, the label that state is 1 is (special
Different label), the modification 0 that state is -1, the general character that state is 0 is constant.
It is specifically as follows in this example:
| a | b | c | x | d | e | f | g |
| 0 | 0 | -1 | 1 | 0 | 0 | 0 | 0 |
After re-flagging
| a | b | c | x | d | e | f | g |
| 0 | 0 | 0 | 2 | 0 | 0 | 0 | 0 |
In character content after the completion of state is applied, if be marked as 2 special state, it executes filtering and kicks out of,
Obtain result:
| a | b | c | d | e | f | g |
| 0 | 0 | 0 | 0 | 0 | 0 | 0 |
