public class RewriteURL
extends AbstractBaseTag

Allow a name, typically either an id or name attribute, to participate in URL rewritting. Some containers such as WebLogic Portal rewrite names so they are unique. This tag will cause the name to be made available from getNetuiTagName JavaScript which is output from the <netui:html> tag.

Attribute Descriptions
Attribute	Required	Runtime Expression Evaluation	Data Bindable
URL	No	No	No
	The value of the URL that will be rewritten.

See Also:

RewriteName, Serialized Form

Example:

In this sample, the id attribute of a <span> tag is set to 'foo'. The actual value that will be written to the rendered HTML may change depending on the application container. (Portal containers sometimes rewrite the id attributes to ensure their uniqueness.) But the value 'foo' can be passed to getNetuiTagName to find the value of the id attribute actually rendered in the browser.

    <span id="<netui:rewriteURL URL="foo"/>">

Beadoc.tagdescription:

Allows a tag name, typically either an id or name attribute, to participate in URL rewritting. Some containers such as WebLogic Portal rewrite names so they are unique. This tag will cause the name to be made available from the getNetuiTagName JavaScript function (which is written to the page by the <netui:html> tag).
