After reading this guide you should have a thorough knowledge of the potential available from Maxthon plugins. The guide also aims to explain the differences between Maxthon plugins and plugins for Internet Explorer. 1.3 Organization of the guide Information about Maxthon plugins is contained in the following three chapters: Chapter 2: Understanding Maxthon plugins (on page 7) - Addresses the background of Maxthon plugins and the ways that plugin support in Maxthon differs from that of Internet Explorer.

Three appendices provide example plugins with code and screenshots: Appendix A: Example of a script button plugin (on page 20) Guide to Creating Maxthon Plugins Page 5 of 33 Revision 0.21 Appendix B: Example of a script sidebar plugin (on page 24) Appendix C: Example of a COM toolbar plugin (on page 27) The fourth appendix gives details of the Maxthon plugin commands. Appendix D: Maxthon plugin commands (on page 31) 1.4 Acronyms and abbreviations Acronyms and glossary terms that appear in Maxthon documentation include: Table 1: Acronyms and Glossary Terms Abbreviation Description COM Component Object Model - a Microsoft platform for software componentry introduced by Microsoft in 1993. COM is used to enable interprocess communication and dynamic object creation in any programming language that supports the technology. CSS Cascading Style Sheets - style sheets comprise external style rules that tell a browser how to present a document. DHTML Dynamic HTML - a term used for a collection of technologies, used together to create interactive web sites by using a combination of a static markup language (such as HTML), a client-side scripting language (such as JavaScript), a presentation definition language (Cascading Style Sheets), and the Document Object Model. DOM Document Object Model - the tree structure of HTML documents. DOM provides an object oriented interface that allows parsing HTML into a well defined tree structure and operating on its contents. Maxthon plugins can then manipulate contents of HTML pages based on this defined structure. HTML HyperText Markup Language - a language designed for the creation of web pages with hypertext and other information to be displayed in a web browser.

Maxthon plugins add functionality to the Maxthon Internet Browser. A plugin aims to enhance the browsing experience by displaying a new page in the browser, affecting something on an existing page, or launching an external tool. Typically, plugins are used for the following purposes: • To integrate an existing web service (such as a search engine, email service, or blog site) with the browser • To integrate an existing local application with the browser • To manipulate the display, elements, and features of a page already displayed in the browser 2.1.1 Examples of existing plugins An enormous variety of Maxthon plugins have been created. To get an idea of the range of functionality available with Maxthon plugins, see the sample below.
