Design and Realization of Directory Tree Navigation

There are many Web-based curriculums in which the chapter navigation is designed as directory tree. In most cases, developing the directory tree requires a large quantity of code and the chapter navigation lacks flexibility as well as extensibility. In our method, we rationally integrated EXTJS with WEBWORK in the JAVA platform. The EXTJS code was directly introduced on the JSP page. The data required by EXTJS is generated by the programs and is transmitted into pages of JSP with the WEBWORK label of WW: PROPERTY. Afterwards, Jobs transforms JSP into SERVLET and sends HTML with static code and script file to client. Practical results show that the proposed method is more valid and feasible.
