Question

有没有办法在java servlet上了解IE文档模式。显然，我试图使用“User-Agent”字符串获取浏览器信息，但我无法从中获取文档模式。

Answer 1

要获取IE的文档模式，请使用以下Servlet类。

代码：

public class DocumentModeOfIE扩展了HttpServlet {

private String documentMode;

 public void init(ServletConfig config) throws ServletException {

}

public void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {

        PrintWriter out = resp.getWriter();
        resp.setContentType("text/html");
        documentMode = req.getHeader("X-UA-Compatible");

       out.println(documentMode);
}


public void destroy() {
}

}

==============将IE文档模式设置为特定标准模式（即IE 7 0r IE8）==============

代码：

使用过滤器......

过滤类：

public class UserAgentCompatibleFilter实现javax.servlet.Filter {

private Logger log = Logger.getLogger("UserAgentCompatibleFilter");
private String compatibilityMode;

public void destroy() {
}

public void doFilter(ServletRequest req, ServletResponse resp, FilterChain chain) throws ServletException, IOException {
    if (compatibilityMode != null) {
        HttpServletResponse res = (HttpServletResponse) resp;
        res.addHeader("X-UA-Compatible", compatibilityMode);
    }
    chain.doFilter(req, resp);
}

public void init(FilterConfig config) throws ServletException {
    compatibilityMode = config.getInitParameter("compatibilityMode");
    if (compatibilityMode == null) {
        log.warn("No CompatibilityMode set for UserAgentCompatibleFilter, thus disabling it");
    }
}

}

web.xml：

http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 版本=＆＃34; 2.5＆＃34;＆GT;

<!-- filter component start -->

<filter>
    <filter-name>UserAgentCompatibleFilter</filter-name>
    <filter-class>com.standardandpoors.ata.web.UserAgentCompatibleFilter</filter-class>
    <init-param>
        <param-name>compatibilityMode</param-name>
        <param-value>IE=8</param-value>
    </init-param>
</filter>

<filter-mapping>
    <filter-name>UserAgentCompatibleFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

<!-- filter component end -->
