ScriptContainer Class

public class ScriptContainer

    extends AbstractBaseTag
    implements ScriptReporter

Acts as a container that will bundle up JavaScript created by other NetUI tags, and output it within a single <script> tag. This is especially needed for Portal web applications, because they often cannot rely on having <html> ... </html> tags to provide a default container. In a portlet, some JSP pages might be included into other JSP pages. Having redundant <html> ... </html> tags in the rendered portlet JSP can result in display problems for some browsers. However, omitting the <html> tag (and the container it provides) can result in cluttered code, especially where Javascript appears in the file. To solve this issue, WebLogic Workshop provides the <netui:scriptContainer> tag.
