hidden

<jato:hidden>

Renders an HTML <input type="hidden"> element.

This tag is only valid when enclosed by both an HTML <form> element and a useViewBean, containerView, or tiledView tag. This tag may not contain any body content.

Example:

<jato:hidden name="nameFilter" defaultValue="*"/>

The above would be rendered into the following HTML:

<input type="hidden" name="PageFoo.nameFilter" value="Jo*">

Attribute Name	Description	Notes
defaultValue	The value to use, if the `DisplayField` view peer's value is `null`. For a hidden tag, "value" refers to the value that will be rendered in the HTML Hidden element's "value" attribute	RTExpr
name	The name of the `DisplayField` peer. This peer must be a child of the current parent `ContainerView`, `TiledView`, or `ViewBean`. The `DisplayField` name is resolved relative to the current parent view. The view peer may be any subtype of `<JATO package>.view.DisplayField` This name may be a qualified view path, using forward slashes ("/") as delimiters. All components in the path except the last must refer to a `ContainerView` or a derivative of `ContainerView` (such as `TiledView`). Both relative and absolute paths are possible. If a name path begins with a forward slash, the name is assumed to be relative to the root view (the `ViewBean`). If the path does not begin with a forward slash, the name is assumed to refer to a child relative to the current container. Two dots ("..") may be used to refer to the container that is the parent of the current container. Examples: `/header/orderList/customerName` (absolute from root view) `orderList/customerName` (relative to current container) `../footer/orderList/customerName` (relative to parent)	Req
	This tag does not support any JavaScript events.
