<ao:iframe>

Renders an <iframe> tag.

Any attribute that has no namespace and begins with param. is added to the src as a URL parameter. The parameter name is the part of the attribute name following param..

When a parameter value is null it is not added. When a parameter value is an Enum, the value is obtained via Enum.name(). If the value is an Iterable, Iterator, Enumeration, or array, then each non-null element is coerced to String as a separate parameter in iteration order. Otherwise, the value itself is coerced to String for the parameter value.

Nested <ao:param> or <ao:params> tags will add parameters after any provided as attributes.

Attributes

Name	Required	Evaluation	Type	Description
id	No	Runtime	String	The id of the element. A nested <ao:id> tag will override this value. For maximum HTML/XHTML and HTML 4/5 compatibility, this value is written as both `id` and `name` attributes.
class	No	Runtime	Object	The CSS class for the element. A nested <ao:class> tag will override this value.
dir	No	Runtime	String	The dir of the element. A nested <ao:dir> tag will override this value.
style	No	Runtime	Object	The CSS style for the element. A nested <ao:style> tag will override this value.
src	No	Runtime	String	The src for the frame content. The src is modified in several ways to make things much easier to work with. A nested <ao:src> tag will override this value. In order to make relative paths predictable, relative paths are interpreted from the current JSP page. In order to keep paths app-relative, if starts with a /, the context path will be prepended to the path. In order to simplify things behind URL mapping schemes, the src is always written starting with '/'. This avoids any need to include any <ao:base> tags. URL rewriting is performed as needed via HttpServletResponse.encodeURL. To support paths in different character sets, a Unicode to ASCII URI encoding is performed on every character that is not defined in RFC 3986: Reserved Characters. To avoid ambiguity, any dynamic parameters or anchors in the URL must have been correctly encoded by the caller. Any directly nested <ao:param> or <ao:params> tag will add parameters to the src.
absolute	No	Runtime	boolean	When `true`, generates an absolute URL for the src for the frame. Defaults to `false`.
canonical	No	Runtime	boolean	When `true`, will generate a Canonical URL. Canonical URLs should be used where per-user response URL rewriting (such as information added when cookies are disabled) should be avoided. Defaults to `false`.
addLastModified	No	Runtime	String	If the src represents a local resource, a parameter of "lastModified=#####" may be automatically added with the timestamp of the local resource to the nearest second. May be one of `true`, `false`, or `auto`. Defaults to `auto`. In auto mode, last modified stamping may be disabled by the client with the `X-com-aoapps-servlet-lastmodified-enabled: false` header. In auto mode, last modified stamping is not performed on Canonical URLs.
width	No	Runtime	Integer	The width for the frame. A nested <ao:width> tag will override this value.
height	No	Runtime	Integer	The height for the frame. A nested <ao:height> tag will override this value.
frameborder	No	Runtime	boolean	The frameborder attribute. Accepts values of `true` or `false`. A non-empty nested <ao:frameborder> tag will override this value. Defaults to `true`.
