摘  要
 本文先對(duì)整個(gè)教學(xué)資源平臺(tái)的開(kāi)發(fā)意義作了一個(gè)簡(jiǎn)述，隨后論述了對(duì)該課題研究的現(xiàn)狀和發(fā)展趨勢(shì)，點(diǎn)明了目前常見(jiàn)的不足之處，并簡(jiǎn)單介紹了該系統(tǒng)的一些特色設(shè)計(jì)和創(chuàng)新設(shè)計(jì)，又針對(duì)本課題的研究重點(diǎn)和難點(diǎn)做了說(shuō)明。緊接著本文介紹了Ajax和java script技術(shù)，通過(guò)對(duì)Ajax的組成、基本原則和原理以及java script的優(yōu)點(diǎn)和可使用的對(duì)象這些方面深入了解了Ajax和java script原理。在這個(gè)理論的基礎(chǔ)上，對(duì)系統(tǒng)的功能設(shè)計(jì)的各方面進(jìn)行了闡述，比如設(shè)計(jì)原則，架構(gòu)設(shè)計(jì)，功能設(shè)計(jì)和角色設(shè)計(jì)。其中在功能設(shè)計(jì)中詳細(xì)介紹了我們這個(gè)教學(xué)資源平臺(tái)的一些創(chuàng)新功能，比如角色權(quán)限模塊、分組概念等等。
 在介紹了Ajax和java script技術(shù)以及設(shè)計(jì)的各方面之后，接下來(lái)對(duì)系統(tǒng)的實(shí)現(xiàn)作了詳盡的敘述，還特意針對(duì)系統(tǒng)的特色模塊配以圖表來(lái)分析，使得整個(gè)結(jié)構(gòu)更為清晰。同時(shí)在實(shí)現(xiàn)的過(guò)程中選取了一些典型的代碼，對(duì)Ajax和java script技術(shù)方面的代碼也作了詳細(xì)的講解。最后對(duì)系統(tǒng)整個(gè)的測(cè)試情況作了介紹。
 相信這個(gè)教學(xué)資源平臺(tái)在今后的教學(xué)使用中會(huì)發(fā)揮更大的作用，同時(shí)這個(gè)平臺(tái)也為今后的擴(kuò)展奠定了堅(jiān)實(shí)的基礎(chǔ)。

Based on AJAX technology platform for the teaching resources background System Design

Abstract
 The article focuses on the entire teaching resources development platform made a brief significance , then discussed the domestic research on the status and development trend , point common understanding of the current shortfall Department , and a brief introduction of the system in some of the characteristics and the design of innovative design, To address the issue of focus and done a difficult note. Immediately after this paper the Ajax and java script technology, and the composition of Ajax. basic principles and tenets of the strengths and java script can be used for the object of these in-depth understanding of Ajax and java script principle . In this theory on the basis of the functional design of the areas discussed, such as the design principles, structure design, functional design and design role. With the functional design details of our teaching resources platform some innovative features such as role competence module, a concept, and so on.
 Tell the Ajax and java script technology, and all aspects of the design, Next implementation of the system are described in detail, but also deliberately targeted system features supported by graphics module analysis the whole structure will be more clear. At the same time realizing the selection process of some typical code Ajax and java script on the technical aspects of the code to explain in detail. Finally, the whole testing system was introduced.
 I believe the platform of teaching resources in the future in education will play a greater role, Meanwhile the platform for the future expansion of laying a solid foundation.

Key words：Ajax，java script，Role and privilege，Create group
