Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, based on the examples herein, which are within the scope of the invention as defined by the claims, will be within the scope of the invention as defined by the claims.
In the front-end system shown in fig. 1, the front-end system is mainly developed by using Google Web Toolkit, and the user experience is finished by using rich Ajax technology and the concept of Web 2.0. And simultaneously, the problem of search engine retrieval is solved by combining the Closure template technology. Thus, a front-end system which is completely based on the Web2.0 technology and also takes search engine retrieval into account is constructed.
(1)Google Web Toolkit
Google Web Toolkit (GWT) is a Java language-based front-end development system developed by Google, inc. of America, capable of compiling Java into JavaScript files for running on the browser front-end. Thus, various problems of JavaScript, such as compile time type detection, inheritance, polymorphism, and large item management, are solved. While the GWT also provides JSNI interface so that it can freely use existing JavaScript libraries.
Another advantage of GWT is that it makes front-end development faster, of higher quality, suitable for development of large commercial projects.
(2)Ajax
Ajax is the core content of Web2.0, and the user experience can be greatly improved through an asynchronous communication mode. The GWT is provided with a Remote Procedure Call system and an object serialization system. The implementation of Ajax is made simpler. By using the Ajax technology, the full page loading of the website can be greatly reduced, the page reflecting speed is faster, and the throughput of a server side can be reduced.
(3)Closure Template
Closure Template is an open source Template system developed by Google, inc. of America that is neutral to the programming language and can conveniently generate HTML pages. The use of close Template can enable search engine optimization because hundred degree search engines cannot effectively retrieve Ajax content. By generating an HTML page and presenting the HTML page to a user and then operating the HTML page structure by using JavaScript, the page can be retrieved by a search engine without losing the user experience of the front end.
(4) Front end animation
To optimize the user experience, the animation tools provided by the GWT are flexibly used.
(5) Search engine optimization
The search engine directly affects the traffic of the website, and the timely retrieval of the website by the search engine is critical to the traffic. Search engine optimization systems mainly use three methods. First, using a close Template ensures that the content of the web site can be found directly by the search engine. Secondly, the release of cargo information content and the format of an HTML document are optimized, and the sequencing result of a search engine is improved. Third, the platform has certain popularity by combining with a third-party content publisher, and finally the aim of improving the sequencing result of the search engine is achieved.
(6) Server push technology
The present platform requires that the server be able to push information to the client, e.g., push update data for some platforms to the user. The conventional HTTP protocol does not implement this function, and therefore requires some special tools to implement server push. The project uses an Atmosphere framework to realize a server-side push function.
(7) Formula symbol display
The project requires the display of a large number of complex formulas, symbols, expressions, rare words, and the like. Whereas general text encoding does not have these complex symbols. Therefore, a system is needed to realize the input and output functions of complex formula symbols. The project adopts MathJax tool, and the tool can better realize the display and input problems of complex formulas and symbols at the browser end.
App: abstraction of the entire front-end system, encapsulating several important parts of the system, such as: history, conducotr, appContext, and the like. The App also manages the creation of the main objects of the front-end system and manages the dependent injection system.
History: the History manager of the front-end system abstracts, and all History changes and History trigger events are managed through a History object.
Conductor: and managing each page of the front-end system, switching popup windows, switching pages, and managing the front-end state through the operation and management of a connector.
Context: the framework object of the front-end system is contained, and the Context is a single-instance global static object, so that any object can conveniently use the framework object.
Page: pages (complex form of Pages) abstractions represent each Page, created and managed by a Conductor. Page uses MVC design pattern, each Page object contains three objects of Model, view, controller, the Model represents the data source of the Page, the View represents the appearance of the Page, the Controller represents the manager of the Page, and the operation and event of all the pages are managed.
Analytics for packaging and managing user interaction information for analyzing user interactions of the front-end system. This module integrates Google analysis for generating user usage data for the entire front end for future enhancements to the front end system design.
The Model is used for packaging and managing all the services related to the data source, can acquire the data source from the server end, can cache the data source, and is convenient for the front-end system to share.
Error Notifier: the front-end log system is managed and all generated front-end logs will be sent to the back-end log system via this service to discover user-triggered front-end errors.
View factor: all View objects responsible for creating the entire front-end system are used to inject into each Page.
Control factor: all the Controller objects responsible for creating the entire front-end system are used to inject into each Page.
Shell: window objects representing the entire application, each object may manipulate shell objects to add and delete elements in the page.
User Agent: an abstraction of the user side contains all user information, such as: browser category, version, cookie, etc.
CS ConductState represents an abstraction of the State of a system. For example: when the user switches to the user main interface, the connector State changes, and other parts of the trigger system change along with the change of the connector State.
Page Manager: page Manager is used to manage the various pages, each of which will have a respective Page Manager used to manage the various operations and triggered events on the pages.
Validation Util: the method is mainly used for verifying user input and ensuring that the user inputs required information, such as verification passwords, mail addresses and the like.
