Brief description
Fig. 1 is the page access process chart first of one embodiment of the invention；
Fig. 2 is the mouse click event process chart of one embodiment of the invention.
Specific embodiment
The present invention is further described with reference to the accompanying drawings and examples.
When the core concept of the present invention is when browser input network address, the HTML literary composition that domain name is not directly pointed to by server
Part is transmitted to client, but this html file is parsed, be sent to client be parsing after static images and its
The coordinates regional set of mouse click event can occur.
When client passes through browser to server transmission accessing page request, with reference to the flow chart of Fig. 1, concrete grammar
It is：
（1）Page parsing is generated initial static images PIC_INIT by server（Jpg form）, extract and chain be may have access on the page
The coordinates regional set ListArea connecing and its corresponding chained address set href, static images are aobvious in browser window
Show effect with using existing method html document by after client interpretation on browser window the effect of display identical；
（2）Server sends to client and comprises initial static images PIC_INIT's and its coordinates regional set ListArea
Response message ResponseMessage (PIC_ INIT, ListArea)；
（3）After client receives initial static images PIC_INIT and its ListArea, PIC_INIT is shown in browser
On；
（4）Server is by the copy of static images PIC_INIT, coordinates regional set ListArea and its corresponding chained address
Set href is saved in this conversation element（Session）Under store path, set up a storing directory with storage after distinguishing
Different pictures.
When client request accesses the link of click position on initial static images PIC_INIT, with reference to Fig. 2
Flow chart, concrete grammar is：
（1）Client obtains the coordinate Location of click position, judges whether Location is included in this initial static
In the coordinates regional set ListArea of picture PIC_INIT, if not existing, do not respond request；If sending to server
Comprise accessing page request message RequestMessage (Location) of click position；
（2）Server obtains the coordinates regional at its place according to the coordinate Location of click position, then by this coordinate
The page parsing that the corresponding chained address in region is pointed to generates new static images PIC_EXE to be visited, and extracting can on this page
Access the coordinates regional set ListArea ' and its corresponding chained address set href ' of link；
（3）Server will comprise the response message of static images PIC_EXE to be visited and its coordinates regional set ListArea '
ResponseMessage (PIC_EXE, ListArea ') it is sent to client；
（4）After client receives PIC_EXE and its ListArea ', PIC_EXE is shown on a web browser；
（5）Server is by the copy of static images PIC_EXE, coordinates regional set ListArea ' and its corresponding chained address
Set href ' is saved in this conversation element（Session）Under store path, a newly-built storing directory is to preserve before distinguishing
Content.
It should be noted that when having the Dynamic Graphs such as gif, flash on the page that request accesses, server extracts on the page
The resource address of all Dynamic Graphs and its coordinates regional set be sent to client, client when showing static images,
According to the coordinates regional of each Dynamic Graph, all dynamic map combining are carried out Dynamic Announce in static images relevant position.Dynamically
The coordinates regional of figure be the width of the coordinate in its upper left corner and this coordinates regional and height or other can accurately express its position
Coordinates regional set（Coordinate as four angles）.
In addition, when server update parses new static images, coordinates regional set and its corresponding chained address collection
During conjunction, can there is following several storage processing mode：
（1）Static images, coordinates regional set and its set of corresponding chained address that server stores before removing, preserve this
The static images of secondary parsing, coordinates regional set and its set of corresponding chained address, at utmost to save memory space；
（2）Static images, coordinates regional set and its set of corresponding chained address that this is parsed by server are stored in this
Under the store path of secondary conversation element, a newly-built storing directory, to deposit content before distinguishing, treats this conversation end（With
The initial static picture PIC_ INIT and its lower all static images PIC_EXE having accessed of this access is closed at family）When,
Server deletes all storage contents of this conversation element again, and " all static images having accessed under it " here refer to
It is in the page representated by this initial static picture PIC_ INIT, the corresponding static images of link having accessed.So, exist
When user's click " retrogressing " returns to the previously visited page, server can quickly recall parsed page figure according to storage catalogue
Piece, it is not necessary to need to again parse the page because of the content before deleting, while saving memory space, improves this session
Access speed and efficiency；When user closes this session of all end-of-pages of this session, delete this meeting of storage
Words All Files, to save memory space；
（3）When device to be stored stores full, the preferential storage content deleted away from the modern time farther out in chronological order.
In present invention server resolving to html file is discussed in detail below by a specific example.
When browser inputs network address http:During //tomcat.apache.org/tomcat-9.0-doc/index.html,
The html file that this domain name is not directly pointed to by server is transmitted to client, but this html file is parsed, should
Html file is designated as HTML_1, then server to HTML_1 resolving is：
（1）HTML_1 sectional drawing is saved as initial static images PIC_INIT by server, and extracts the institute on PIC_INIT
There are Dynamic Graph and link event
（1a）HTML_1 is carried out sectional drawing and saves as initial static images PIC_INIT by server
This step can be completed by the class with analytical capabilities, as can be by Robot class in JSP
Robot.createScreenCapture () completes, can be by WebBrowser class in ASP.NET
WebBrowser.DrawToBitmap () completes.
（1b）Extract all of Dynamic Graph of HTML_1
Dynamic Graph is by judging that whether the form that src points to file is the form of Dynamic Graph（As gif, mp4, swf etc.）Determine
, judge that sentence can be $ (" img [src $=gif], embed [src $=swf] ").The extraction content of Dynamic Graph includes：Dynamic
The resource address of state figure（src）, coordinate（X, y）And size（Width, height）.The Dynamic Graph filtering out is saved as
animate{(src,x,y,height,width),….}.This step can be completed by embedded jquery selector.
（1c）Extract the link event of HTML_1
Extract the coordinates regional set ListArea of all addressable link places label in HTML_1（I.e. x ', y ',
width,height）And its corresponding chained address gathers (href), save as link event set lnk href1,
ListArea1；href2, ListArea2；href3 ListArea3；...., wherein, { href1, ListArea1 } represents the
One link event, { href2, ListArea2 } represents second link event, and { href3, ListArea3 } represents the 3rd
Individual link event, the like, multiple link event group chainings are taken over a job the set of part.For example, there is one to be linked as<a href
=“http://123.233.123.86/login.jsp”>, preserve chained address href=http://123.233.123.86/
Login.jsp, the coordinates regional ListArea of link place label（I.e. x ', y ', width, height）Can be by jquery's
Offset (), $ (obj) .width (), $ (obj) .width () method obtains.
It is to be appreciated that（1）In（1a）、（1b）、（1c）It is independent of each other and can carry out simultaneously,（1）After the completion of, just can carry out
（2）.

<!DOCTYPE html>
<html>
<head>
</head>
<body>
<div>
<img src”PIC_INIT”/>
</div>
</body>
</html>
（2.2）Server will（1b）The middle animate preserving Dynamic Graph embeds（2.1）HTML_2 in, embedded form can be：
<div>
<embed src =”src.swf ” style=”position:absolute; left=x; top:y;
width:width; height:height”>
<img src =”src.gif ” style=”position:absolute; left=x; top:y; width:
width; height:height”>
</div>
（2.3）Server is（2.1）In HTML_2 add event, add event main contents have：1. any one when being in
