Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The present invention is according to MVC (Model-View-Controller, model-view-controller) modular concept, the tree of demonstrating data is divided into data, demonstration and controls the independent respectively realization of three parts, thereby increase to realize the reusability of tree code, improved the dirigibility of code revision, maintenance.
Fig. 1 shows MVC structure of models principle, and wherein, view (View) is that the user sees and mutual with it interface.Concerning web application, view is exactly by HTML, Macromedia Flash and the interface formed as elements such as some identifiable languages such as XHTML, XML/XSL or WML and Web services.Model (Model) provides data for a plurality of views.Because the code that is applied to model only need be write once and just can be reused by a plurality of views, so reduced the repeatability of code.Controller (Controller) is accepted user's input and is called model and view goes to finish user's demand.When data are handled, at first controller receives user's request, and determine that call which model handles, model comes the request and the return data of process user with service logic then, last controller formats the data that model returns with corresponding view, and presents to the user by presentation layer.
The MVC model is as a kind of INTERFACE DESIGN pattern of maturation, in the industry cycle be extensive use of, use the reusability that this Design Mode can improve code, reduce the degree of coupling of data representation, data description and referencing operation, improve maintainability, extensibility, dirigibility and the encapsulation property of software simultaneously.The present invention uses the tree demonstrating data according to the MVC modular concept in the WEB page.
Fig. 2 shows the realization of tree in the B/S structure provided by the invention and the corresponding relation of MVC model, and server end is realized the Model part in the MVC pattern, and browser end is realized View and the Controller part in the MVC pattern.
Fig. 3 shows the realization principle that data is represented by tree provided by the invention:
At server end, at first the raw data that needs are represented is preserved, and can leave in database, the memory object, also can directly obtain from other position.Generally all be level or tabulation relation between the data item of the raw data that these are saved, can use the mode of tree to present., can be information such as device id, title, IP and state for example for equipment.
Secondly, raw data is converted to the expression data that suitable tree represents, conveniently to show and to handle.As one embodiment of the present of invention, adopt XML (eXtensible Markup Language, extend markup language) to describe the raw data among the Model, the required information that represents can be described effectively, make things convenient for processing, conversion and the expansion of program.The XML data that generate also comprise associated description, the control information of the node of tree except that comprising primary data information (pdi), for example specify each node of tree all to comprise a check box etc.At last, the list of server end by user's operating result resolved user's request, revises raw data and makes the data sync of server end and browser end.
At browser end, when user's open any browser, browser is downloaded the JavaScript file from server end, and this JavaScript file represents request according to the user and generates the data exhibiting steering order.When the tree initialization shows, browser end obtains with the user from server end according to the data exhibiting steering order and asks corresponding XML data, select to download relevant XSLT (the eXtensible Stylesheet LanguageTransformations that represents form, extendible style sheet language conversion) file, by XSLT the XML data-switching is become HTML/XHTML, HTML/XHTML is shown to the user with the form of tree view by browser end.Once more, the state that shows by JavaScript document change tree is with response user's operation, and for example the user launches the node of tree, then shows the child node of this node and changes the state of father node.At last, if the user changes the raw data of server end to the action need of tree, then the operating result of user's operation is submitted to server-side processes by Form or XMLHTTP mode, server end is resolved user's request, change raw data, make the data sync of server end and browser end.
Fig. 4 shows the realization flow by the tree demonstrating data provided by the invention, and details are as follows:
In step S401, browser end comprises the page of tree according to user's operation initialization, prepares to carry out next step data presentation, downloads the JavaScript file from server end, to data represent and user's request is controlled.
In step S402, browser end, is downloaded from server end by browser end to the corresponding XML data of server end request and select corresponding XSLT file according to the tree type of appointment in the page and parameter;
Server end can generate the XML data with all raw data in advance in the present invention, when browser end request XML data, directly returns XML data to browser through end.Also can generate the XML data, return to browser end again according to the request of browser end;
In step S403, browser end uses XSLT that the XML data are converted to HTML/XHTML, presents to the user with the tree view;
Can not use XSLT to change in one embodiment of this invention and generate HTML/XHTML, but in the JavaScript of browser end, directly use DOM (DOM Document Object Model) analyzing XML to generate HTML/XHTML.But can lose dirigibility and the ease for maintenance of using XSLT like this, because DOM resolves this mode and the rule of conversion need be write in the source code of browser end, if the representing then need to revise source code of change tree to change transformation rule, and the conversion of using XSLT to carry out the XML data only need select the corresponding XSLT file of download to get final product from server end according to the form that will represent, and prerequisite is that the XSLT file has been designed and be kept at server end by the developer certainly.
In step S404, the JavaScript of browser end response user operation changes the tree internal data, for example launch tree node, change node state etc.;
In step S405, if the user then submits to server-side processes by Form or XMLHTTP mode with user's operating result to the raw data on the action need change server end of tree.
In one embodiment of this invention, the JavaScript, XSLT file that download to browser end can viewed device end buffer memorys, server only needs to send the XML data at every turn, and do not need to send all data that produce HTML/XHTML, thereby significantly reduced data transmission, save bandwidth, improved the speed of customer access network.
Fig. 5 shows the structure of passing through the system 100 of tree demonstrating data provided by the invention, and 101 pairs of raw data that represent by tree of data processing unit are stored and conversion process, generates to be suitable for the expression data that tree represents.Original data storage administration module 1012 is used to preserve or obtain raw data to be represented from exterior storage medium.Data representation module 1011 is converted to raw data and is fit to the expression data that tree represents, conveniently to represent and to handle.As one embodiment of the present of invention, adopt XML to describe raw data.
Data presentation converting unit 102 becomes the HTML/XHTML code with the XML data-switching, is represented to the user by the mode of browser end with the tree view.Mutual representing of 103 pairs of data of control module controlled, represent request according to user's data and generate the data exhibiting steering order, and the response user is to the operation of tree view, when the user changes the raw data of server end to the action need of tree view, mutual control module 103 is submitted to user's request processing module 1013 with user's operation requests with Form or XML HTTP mode, user's request processing module 1013 is revised corresponding raw data according to this operation requests, makes the data sync of server end and browser end.
Need to prove that the present invention is not limited to HTML/XHTML by the form of tree demonstrating data, can also be Flash (the mutual cartoon making instrument of a kind of webpage) or Applet (a kind of Java Applet that is embedded in the html file), promptly by XSLT with the XML data-switching or directly offer tree control among Flash or the Applet.
The above only is preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of being done within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
