Abstract
The invention belongs to the technical field of network, in particular to a method for implementing white board clear screen synchronization on a webpage. The method comprises the following steps that: when a user opens the webpage and loads flash, the flash establishes permanent connection with a Socket server and starts to monitor; when the user operates the webpage to perform clear screen operation on white board contents, a Flash interface is called and a clear screen data marker is imported, and the Flash calls API to transmit the data to the Socket server; a target user opens the webpage and loads a Flash plug-in unit, establishes permanent connection with the Socket server and starts to monitor; and when the Flash receives the clear screen data marker transmitted by the Socket server, a webpage white board clear screen function is called to completely clear traces written on the white board so as to implement the white board clear screen synchronization. The method can implement completely webpage-based instant white board clear screen synchronization and has the advantages of convenience, rapidness and high efficiency.
Description
Technical field
The invention belongs to networking technology area, be specifically related to realize on a kind of webpage the synchronous method of blank cls.
Background technology
The development of Internet technology can be stayed indoors us and has just been realized instant messaging, with good friend's chat, with affiliate's negotiation or the like.At present, the immediate communication tool that downloads and installs based on needs is as MSN, QQ, POPO has been subjected to everybody liking deeply, and it provides new approach for people's communication, information interchange, is another the important information interchange mode except mobile phone, fixed line, Email.By these instruments, the user can realize single or many people video, can hold the network teleconference, can carry out network remote education, and then allows the interchange cost between people and the people reduce greatly, has improved efficient simultaneously.Text communication, voice communication, video communication are instant messaging most important three big functions, and along with the abundance day by day of The development in society and economy and bandwidth resources, the application of instant messaging is more and more universal.Along with the informationization in fields such as commerce, education speeds up, simple text exchanges the demand that can not satisfy people's commercial affairs sexual intercourse stream and writes, discusses enterprise plan book problem as exchanging paper, analyzes various difficult problems etc.People use electronic whiteboard that demo content is carried out lecture, explanation as input characters etc. usually, when lecture explain finish and to the operation of blank cls after, other is still shown content before the cls by demo end, if the cls operation can't be synchronized to other and will be caused information inconsistency by demo end, thereby causes unnecessary misunderstanding.Especially in the occasion of some high seriousness, such as in the paper demonstration to the cls operation of blank, all should be synchronously other by demo end, otherwise, must cause error in data, thus the effect of influence interchange.At present, can't realize the synchronous cls of electronic whiteboard,, also need download control, and hardware, expense etc. is all had certain requirement even if realize based on webpage, can not fine universal masses.
Realize on a kind of webpage that the synchronous method of blank cls is intended to solve the variety of issue that the blank cls exists synchronously in the webpage, complete blank cls synchronization solutions based on webpage is provided, do not need to download any control, can be simply, efficiently, immediately synchronously, be convenient to embed in the web application such as video conference, long-distance education, be a kind of really can popular universal emerging technology.
Summary of the invention
The objective of the invention is: provide and realize the synchronous method of blank cls on a kind of webpage.
In order to achieve the above object, technical scheme of the present invention is: realize on a kind of webpage may further comprise the steps the synchronous method of blank cls:
1) source user is opened webpage, and webpage loads the Flash plug-in unit automatically, and Flash sets up with the Socket server and forever is connected, and begins to monitor the transmission of Socket server data;
2) blank in the source user operation web page when carrying out the cls operation, calls the Flash interface and imports blank cls data into, and Flash calls API data are sent to the Socket server then, and the Socket server is given other targeted customer with the data forwarding that receives;
3) targeted customer opens webpage and loads the Flash plug-in unit, automatically set up to be connected and to begin to monitor the Socket server data and transmit with Socket server permanent, when the blank cls data of Socket server forwards source user, targeted customer's Flash plug-in unit can receive these data, Flash invoking web page blank cls function, the webpage function is removed the vestige in the blank according to instruction, promptly realizes the synchronous of blank cls.
In the technique scheme, step 1) comprises following process:
Source user is opened webpage, and webpage loads the Flash plug-in unit automatically, and the Flash plug-in unit is set up by the XMLSocket class and is connected with the permanent of Socket server, and begins to monitor the transmission of Socket data in server.
In the technique scheme, step 2) comprise following process:
2a) the blank in the source user operation web page, when carrying out the cls operation, webpage calls the Flash interface and imports the instruction of blank cls into;
After 2b) Flash received the instruction of blank cls, the method for call XML Socket class sent to the Socket server with the instruction of blank cls;
After 2c) the Socket server received the blank cls data that source user sends over, data forwarding is connected to all needed synchronous targeted customer immediately on the Socket server.
In the technique scheme, step 3) comprises following process:
3a) targeted customer opens webpage, loads the Flash plug-in unit automatically, and the Flash plug-in unit is set up by the XMLSocket class and forever is connected with the Socket server, and begins to monitor the transmission of Socket data in server;
3b) when the blank cls data of Socket server forwards source user, targeted customer's Flash plug-in unit can receive these data by the monitor method of XMLSocket, and Flash uses the blank cls function of External Interface.call method call webpage JavaScript;
3c) webpage JavaScript function is according to the instruction of blank cls, and the blank cls of targeted customer's blank cls and source user action at this moment is consistent, and promptly realizes the synchronous of blank cls.
Technical scheme steps 1) XMLSocket in the process can be used for the class of communication for XMLSocket, socket or other.
The present invention compared with prior art has the following advantages:
1), need not to download fully based on webpage.
2) employing has high instantaneity, high fluency based on the instant messaging technology of Socket.
3) realize that principle is simple, process is clear, is convenient to embed in the internet, applications such as each big video conference, long-distance education.
Description of drawings
Figure of description is a detail flowchart of the present invention.
Embodiment
Realize the synchronous method of blank cls on a kind of webpage, may further comprise the steps:
1) source user is opened webpage, and webpage loads the Flash plug-in unit automatically, and Flash sets up with the Socket server and forever is connected, and begins to monitor the transmission of Socket server data;
2) blank in the source user operation web page when carrying out the cls operation, calls the Flash interface and imports blank cls data into, and Flash calls API data are sent to the Socket server then, and the Socket server is given other targeted customer with the data forwarding that receives;
3) targeted customer opens webpage and loads the Flash plug-in unit, automatically set up to be connected and to begin to monitor the Socket server data and transmit with Socket server permanent, when the blank cls data of Socket server forwards source user, targeted customer's Flash plug-in unit can receive these data, Flash invoking web page blank cls function, the webpage function is removed the vestige in the blank according to instruction, promptly realizes the synchronous of blank cls.
