button


<jato:button>

Renders an HTML <input type="submit"> 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:button name="processForm"/>

The above would be rendered into the following HTML:

<input type="submit" name="PageFoo.processForm" value="Process">

Attribute Name

Description

Notes

accessKey

Assigns an access key to the rendered HTML element. In general, the access key should be included in label text or wherever the access key is to apply.

RTExpr

defaultValue

The value to use, if the DisplayField view peer's value is null.

For a button tag, "value" refers to the value that will be rendered in the HTML element's "value" attribute

RTExpr

disabled

Valid values: "true" or "false"

Disables the HTML control for user input.

  • Disabled controls do not receive focus
  • Disabled controls are skipped in tabbing navigation

If not specified, "false" is assumed.

RTExpr

elementId

Assigns a name to an element. This name must be unique in an HTML document. Please note, this corresponds to the HTML "id" attribute. It has no specific meaning to the JATO framework.

The id attribute has several roles in HTML:

  • As a style sheet selector
  • As a target anchor for hypertext links
  • As a means to reference a particular element from a script

RTExpr

extraHtml

Arbitrary HTML that will be rendered just prior to the closing ">" of this HTML element

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 must be of type <JATO package>.view.CommandField

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

src

An image URL if this button is to be rendered as an image button.

RTExpr

style

CSS styles to be applied to this HTML element.

RTExpr

styleClass

CSS stylesheet class to be applied to this HTML element.

RTExpr

tabIndex

Specifies the position of the current element in the tabbing order for the current document. This value must be a number between 0 and 32767.
