public class InputImageTag
extends InputTagSupport

Tag class that generates an image button for use in HTML forms, e.g:

<input name="foo" type="image" src="/app/foo.gif" alt="foo"/>

Provides a couple of facilities above and beyond using plain HTML tags. The main advantage is a localization capability. The tag looks in the Stripes Field Name message bundle for resources to be used as the src URL for the image and the alt text of the image. In order it will look for and use:

• resource: actionPath.inputName.[src|alt]
• resource: inputName.[src|alt]
• tag attributes: src and alt

If localized values exist these are preferred over the values specified directly on the tag.

Additionally if the 'src' URL (whether acquired from the tag attribute or the resource bundle) starts with a slash, the tag will prepend the context path of the web application.

Stripes 1.3
