The 3rd constructing elements: literal-": first aid is complained ", font-normal, position-(44,16)
The 4th constructing elements: literal-" 1 summary ", link-" T01.htm ", font-normal, position-(12,24)
The 5th constructing elements: literal-": geography and history ", font-normal, position-(44,24)
……
(3) the composition module is used to store and has above-mentioned all constructing elements that comprise composition information, after all constructing elements are arranged by composition information, can determine whole Webpage physical size (W, H), as W=176, H=560.
(4) display module has write down the size and the position of physics display screen, and it also comprises a sliding window of virtual rectangle, and this cunning window is the mapping position of viewing area at whole Webpage.Under mode standard.The display area size that can use for java applet on the Nokia7610 mobile phone be that (Wp, Hp)=(176,140), the position of cunning window is designated as that (Xp Yp), is initialized as (0,0), as shown in Figure 4.
(5) the keyboard response module can be monitored keyboard, and this mobile phone comprises one common five to key, and as shown in Figure 5, it comprises upper and lower, left and right, 5 sub-buttons of selection (stopping).In case the user has actuation of keys, key information will directly be delivered to the sliding window updating module, and key information comprises key name and state, and state is divided into to be pressed or discharge.
Present embodiment is an example with the static page pattern only.Behind the initialization above-mentioned parameter, can start the keyboard respond module, the monitoring users input, the top area of the whole Webpage of screen display keeps transfixion.
If the user presses five down Arrows in key, after the keyboard response module listened to user's input, meeting also sent to display module with key information.Display module enters the branched program that response " is pressed down Arrow ", will slide the window position line down, promptly upgrades Yp with Yp+ Δ Y, and Δ Y is a predefined amount of moving down, if move down Δ Y＞0, if on move Δ Y＜0.Display module selects to fall into the constructing elements when advancing slip window again from the composition module, draw on physical screen one by one, at this moment demonstration has been moved down the content of pages of delegation on screen, and screen continues to keep transfixion, as shown in Figure 6.
If the user presses five options buttons in key, after the keyboard response module listens to user's input, can enter the branched program that response " is pressed options button ", from the link of current selection, extract web page address, and this address is sent to communication module begin new " being written into-resolve-composition-demonstration " process, the page of finishing by hypertext link switches.
So far, we have obtained the html browser that can browse the standard webpage, can select the hypertext link in the page to carry out page switching.But for being hidden in the more link page afterwards, the user is difficult to locate apace and visit.For the ease of understanding and consulting, the logical relation between each information webpage can form logic relation of inclusion as shown in Figure 7 by its classification grouping.
In the present embodiment, above-mentioned logic relation of inclusion is pressed among the HTML＜UL〉...＜LI〉...＜/UL〉listings format write as the directory tree file, and is as follows:＜html〉＜head〉＜/head〉＜body〉＜P〉＜A href=" Index.htm "〉Hong Kong tourist handbook＜/A〉＜/P〉＜UL 〉

The present invention uses among the HTML＜UL〉...＜LI〉...＜/UL〉listings format record directory tree, advantage is that the html file that obtains can normally show in the html browser of standard, and the hypertext link that comprises all information pages on the page, make the user can fully understand all content of pages, the specific information page of fast access plays the effect of complete index.
But because the screen of mobile phone is little, operation is slow, when browsing and select to comprise the page of a large amount of hypertext links, has to frequently enter a new line up and down complex operation.The present invention adds catalogue and resolves and the directory management module, and above-mentioned standard format is carried out special parsing, realizes the demonstration and the selection of multi-level catalogue at last with dynamic tree structure, makes clear layer to show compactness, and operation is succinct.
Among the use HTML that the present invention proposes＜UL〉...＜LI〉...＜/UL〉technical scheme of listings format record directory tree, play both compatible conventional browser, help the effect of dynamic catalogue browser again.
When browsing, communication module is read in a catalogue file of writing with html format from local resource, 206 pairs of these catalogue files of catalogue parsing module carry out grammatical analysis, according to＜LI〉mark is divided into a plurality of data cells with html source file, a node in each data cell corresponding catalogue tree.Node in the directory tree is divided into two kinds of terminal node and logic nodes.The all corresponding specific information webpage of each terminal node, this node comprise title and with the web page address information of hypertext link form.Logic node plays logic groups, and it shows as＜LI at above-mentioned html file with the plurality of sub node organization of same classification together〉and a pair of＜UL of closelying follow thereafter ...＜/UL 〉.Logic node has and launches and shrink two states, and under deployed condition, the child node it under will show in catalogue and directly show in setting; Under contraction state, the child node under it does not show demonstration in the tree in catalogue, as shown in Figure 8.
Directory management module 207 all nodes (comprising logic node and terminal node) that parsing module 206 generates that are used to save contents, construct the catalogue demonstration tree that is used for the small screen of a compactness simultaneously according to the state of current logic node, constitute all constructing elements that this shows tree for 203 outputs of composition module, on screen, show.The present invention uses recursive mode structure catalogue to show tree, concrete operations are: the position of first initialization constructing elements, with the root node is present node, title, link and its display position of newly-built constructing elements record present node, judge then whether present node is the logic node that launches, if its child node of sequential access then is that present node repeats aforesaid operations with each child node; If not then returning higher level's father node, visit next child node, until the logic node of having visited all expansion and be in terminal node with one-level.Above-mentioned behaviour the result be the traversal of directory tree being carried out depth-first, shield all branches it under with the node with contraction state, show that setting is the compact representation of whole directory tree.

At the above-mentioned constructing elements that is used for the Display directory tree that constructs, according to its node-classification, add different icons or color or position indentation, just can show the logical relation between them more intuitively, as shown in Figure 9.
For customizing catalogue, the hobby according to the user shows tree, keyboard response module 205 input of monitoring users constantly, and the user can select specific node, launches or the contraction node, in order to the show or hide detailed information.When technology realized, a kind of common technical scheme was two specific keys of definition, as " # " and " * ", and expression " expansion " and " contraction " order respectively.But use too much artificial definition not directly perceived, the user forgets easily or mixes up unrest.In addition, the definition of multikey must bring the extra motion of user's thumb, in portable equipments such as mobile phone, is easy to generate in a rush sensation in the one-handed performance, reduces operating efficiency.The two or more different functions of definition are unlikely at first sight on same button.But the present invention utilizes the status information with this key associated node dexterously, has solved the problem of button multiplexing.As the explanation in above-mentioned system architecture and the workflow, when the user presses options button, if the state of the node of current selection is a contraction state, then launch this node, if the state of the node of current selection is a deployed condition, then should shrink node, effect is intuitively direct, be difficult for getting wrong, need not remember.
In the present embodiment, if the user presses five options buttons in key, keyboard response module 205 can listen to user's input, enter the branched program that response " is pressed options button ", wherein, if current what browse is the catalogue text, then the directory tree node information with the current constructing elements correspondence of choosing sends to directory management module 207, the directory management module is judged this node types and state, if terminal node is then issued the webpage that communication module 201 is directly opened this node correspondence with its chained address; If the logic node that shrinks then is changed to expansion with its state, otherwise then is changed to contraction, re-construct catalogue then and show that tree and update displayed are on screen.So, user's direction of passage key just can be browsed catalogue up and down and show tree, on interested node, press options button, realize the automatic expansion and the contraction of sub-directory under this node, for example on the node that shrinks, press options button and can launch child node under this node automatically, on the node that launches, press options button and can shrink this node automatically, do not show the child node under it.So, the user can effectively utilize the small screen, the node of oneself being concerned about is most shown clearly, and unconcerned node stashes automatically, and whole bibliographic structure is simply clear.In addition, the user needn't open the new page when browsing whole directory tree, and what do not have webpage is written into " returning " expense with the user repeatedly, the browse efficiency height, and operation is few.
Be the workflow of browser in a preferred embodiment of the invention as shown in figure 10, the front has been described most of workflow wherein.As can be seen from Figure, during work,
Be written into web page files or catalogue file earlier;
Sliding window in the initialization display module then;
And then judge the whether catalogue file be written into, resolve generation directory tree (wherein comprising all nodes) if then enter catalogue, and then according to each node types and state, generate corresponding catalogue and show tree (wherein include only the current constructing elements that needs those nodes of demonstration, do not comprise the constructing elements that is hidden node);
If what be written into is web page files, then carry out corresponding webpage and resolve, generate corresponding constructing elements;
The constructing elements that above-mentioned catalogue is shown tree or webpage stores in the composition module;
The constructing elements that display module is selected to fall into the sliding window of current demonstration from the composition module is drawn at screen one by one, and the sliding window localized area in the complete page is mapped on the physical screen;
Start the key command of key-press module monitoring users input then;
If what press is directionkeys up and down, then the position to sliding window adjusts accordingly;
If what press is options button, then judge again when pre-treatment whether be catalogue file, be not then to be written into new web page files by current link; Be to judge again then whether selected be logic node, as be not expression selected be terminal node, the address information that needs to comprise by this node is written into corresponding web page files, if logic node, then change its state, be originally that expansion then becomes contraction, be originally that contraction then becomes expansion, and then, generate corresponding catalogue and show tree again according to each node types and state.
Present embodiment is to write with Java language, and has debugged on the Nokia7610 mobile phone and passed through.Present embodiment can be written into basic html web page and correct the demonstration, and present embodiment can the catalogue file and shown on screen with tree structure simultaneously.By the up and down arrow keys of mobile phone five in key, the user can enter a new line and select the hypertext link in the page, choose the node in the directory tree after, press options button and will launch or shrink sub-directory under it.Whole process links up smooth, the catalogue folding freely, all operations only uses a thumb five to finish nature simple to operation on key at this.
As seen, the present invention is on the basis of the environment for use of fully studying the cellphone subscriber and experience, on the basis of existing browser, catalogue parsing module and directory management module have been added, thereby function with normal static page browsing and dynamic tree-like catalogue browsing, make things convenient for the complex logic relation of handheld redio communication device user between each page of fast browsing on the small screen, clear logic is succinct, and is simple to operate flexible, and response fast directly.
When concrete Interactive function designed, the present invention emphasized to reduce user's operation and memory burden, utilized the state defined function of current selecteed node, if the state of selecteed node is to launch, then shrank this node, otherwise launched this node.Be characterized in mutual flexibly, effect is directly perceived, be difficult for getting wrong, need not remember.
In addition, only introducing limited several catalogues in designed system of the present invention and the flow process resolves and the directory management unit, the communication module of multiplexing standard, composition module, display module and keyboard response module, make both compatibility standard static Web page functions of browse of browser, support the fast browsing of dynamic directory tree again.Simplify logic, multiplexing structure effectively, make the not malfunctioning again activity of clear in structure compactness of system.
In addition, standard scheme is adopted in the definition of catalogue file of the present invention, both can normally show on the conventional HTML browser, can show by dynamic optimization in directory browser of the present invention again.
