【正文】 r ) Brendan Eich has invented this language, started from 1996, already appeared in all Netscape and in the Microsoft browser. The ECMA262 development began in 1996, in 1997 July, the ECMA general meeting has accepted its first edition. Script script uses one specific descriptive language, rests on certain form pilation to be possible the execution document, is also called as great or the batch run document. The script usually may transfer temporarily by the application procedure and carry out. Each kind of script present widely is applied in the homepage design, because the script not only may reduce the home page the scale and raises the homepage browsing speed, moreover may enrich the homepage performance, like animation, sound and so on. Cites a most mon example, w hen we click in the homepage the Email address can transfer Outlook Express or the Foxmail this kind of mail software automatically, is realizes through the script function. Also because of script these characteristics, the human w ho harbors ulterior motives by some are often using. For example joins some destruction puter system39。 Is more convenient to Bean factory expansion ApplicationContext we to realize the J2EE application。s logic is sealed in marks and in the JavaBeans module, and ties up in the script, all scripts in server end movement. Because core logic is sealed in marks and in JavaBeans, therefore the Web administrative personnels and the page designer, can edit and use the JSP page, but does not affect the content the production. In the server end, the JSP engine explained that the JSP marking and the script, produce the content which requested, and (or XML) page39。s dynamic content originally. Production content39。s work. When pared with two documents, this plugin unit first inspects whether to have another plugin unit to be possible to explain these document structure. If found one, it to the plugin unit inquiry related file organization information w hich found, and used this information in the parison process. May see that the modular construction was Eclipse has provided the huge flexibility, and provided one to be possible to support the massive application procedure platform which the original design has not expected. 4 Structs function synopsis Struts is a MVC frame (Framework), uses in developing Java fast the Web application. Struts realizes the key point in C(Controller), Action w hich and we have custommade including ActionServlet/RequestProcessor, was also V(View) provides a series of rows to have custommade the label (Custom Tag). Spring is a light vessel (lightweight container), its core is the Bean factory (Bean Factory), with constructs M(Model) w hich we need. Above this foundation, Spring has provided AOP (AspectOriented Programming, face stratification plane programming) realization, provides under the nonmanagement environment with it to declare services and so on way business, security。s limitation exposes day by day. In order to solve this problem, the people also took many tortuous paths, has used some not good method, for instance increases many attribute results to HTML bees the code very extremely fat, turns the picture the text, excessively ma ny es the typesetting using Table, expresses the w hite space with the blank picture and so on. Appears until CSS. CSS may be a homepage design breakthrough, it has solved the homepage contact surface typesetting difficult problem. May such say that HTM L Tag is mainly defines the homepage content (Content), but CSS decided how these homepage content does demonstrate (Layout). The CSS English is Cascading Style Sheets, Chinese may translate the tandem cascading style sheet. CSS may divide into three kinds according to its position: In inlays the style (Inline Style), internal cascading style sheet (Internal Style Sheet), exterior cascading style sheet (External Style Sheet). 6 Js script language synopsis JS is javascrip, Javascript is one kind the script l anguage w hich es by the Netscape LiveScript development, the main purpose is to solve the server terminal language, for instance Perl, carryover speed question. At that time served the end to need to carry on the confirmation to the data, because the n etwork speed was quite slow, only then , the confirmation step waste39。用 JSP 訪問可重用的組件，如 Servlet、 JavaBean 和基于 Java 的 Web 應用程序。 JSP 與 Java Servlet 一樣，是在 服務器端執(zhí)行的，通常返回該客戶端的就是一個 HTML 文本，因此客戶端只要有瀏覽器就能瀏覽。由于核心邏輯被封裝在標識和 JavaBeans 中，所以 Web 管理人員和頁面設(shè)計者，能夠編輯和使用 JSP 頁面，而不影響內(nèi)容的生成。標準的JSP 標識能夠訪問和實例化 JavaBeans 組件，設(shè)置或者檢索組件屬性，下載 Applet，以及執(zhí)行用其他方法更難于編碼和耗時的功能。 JSP 技術(shù)很容易整合到多種應用體系結(jié)構(gòu)中，以利用現(xiàn)存的工具和技巧，并且能擴展到支持企業(yè)級的分布式應用中。 Eclipse 由一個小程序?qū)訕?gòu)成，其中包含許多功能模塊或 Eclipse 術(shù)語中所謂的“插件”。比較兩個文件時，該插件首先檢查是否有另一個插件可以解釋這些文件的結(jié)構(gòu)。 Structs 是一組相互協(xié)作的類、 servlet 和 JSP 標記，它們組成一個可重用的 MVC框架。就 Struts 而言，這是通過作為實際業(yè)務邏輯“瘦”包裝 的 Action 類完成的。 Struts 的控制器是將事件（事件通常是 HTTP post）映射到類的一個 所料 —— 控制器使用配置文件以使您不必對這些值進行硬編碼。 ActionServlet （ Command） 使用 perform（）方法將參數(shù)化的類傳遞給 ActionForm .仍然沒有太多討厭的 （） 調(diào)用。 5 CSS 簡介 CSS 的編輯方法同 HTML 一樣，也可以是任何文本編輯器或網(wǎng)頁編輯軟件，還有專門用來編輯 CSS 的軟件。 CSS 的英文是 Cascading Style Sheets，中文可以翻譯成串聯(lián)式樣式表。這個標準基于 JavaScript (Netscape) 和 JScript (Microsoft)。例如在腳本中加入一些破壞計算機系統(tǒng)的命令，這樣當用戶瀏覽網(wǎng)頁時，一旦調(diào)用這類腳本，便會使用戶的系統(tǒng)受到攻擊。所有的腳本都是通過這一方法實現(xiàn)的
