t:headerLink

The t:headerLink tag extends the JSF commandLink tag and adds conditional rendering support based on user roles. It also adds the standard HTML target attribute to the generated hyperlink to instruct the browser on how to open the link.

Example:

<t:headerLink></t:headerLink>

Tag Attributes

accesskey	String

The accesskey attribute is a standard HTML attribute that sets the access key that transfers focus to this element when pressed.

action	String

The action attribute accepts a method-binding expression for a backing bean action method to invoke when this component is activated by the user. An action method must be a public method with no parameters that returns a String. The returned string represents the logical outcome of the action (eg. "success", "failure", etc.) and is used by the JavaServer Faces MVC framework to determine which view to display next.

actionFor	String

The actionFor attribute expects a comma-separated list of component IDs associated with the component generating the action event.

actionListener	String

The actionListener attribute accepts a method-binding expression for a backing bean action listener method that will be notified when this component is activated by the user. An action listener method must be a public method with an javax.faces.event.ActionEvent parameter and a void return type.

binding	String

The value-binding expression linking this component tag to a backing bean property.

charset	String

The charset attribute identifies the character encoding of the resource linked to by this hyperlink.

coords	String

The coords attribute sets the position and shape of the hotspot on the screen when using this link with a client-side image map.

dir	String

The dir attribute is a standard HTML attribute that overrides the default text directionality for this component. The values accepted for this component are "LTR" (left-to-right) and "RTL" (right-to-left).

disabled	String

The disabled attribute is a boolean flag that when set to true indicates that this component should not receive focus or be included in a form submit.

disabledStyle	String

This attribute defines a CSS style to be applied to the tag when the disabled attribute has a boolean value of true.

disabledStyleClass	String

The disabledStyleClass attribute defines a CSS class to be applied to the tag when the disabled attribute has a boolean value of true.

enabledOnUserRole	String

The enabledOnUserRole attribute determines if this component will be rendered normally or not depending on the user's roles.

forceId	String

The forceId attribute expects a boolean value, that when set to true, forces the tag to render its ID exactly as specified in the ID attribute. This allows you to apply CSS styles to the tag and to reference it in JavaScript by ID, which is typically not possible using the default JSF component ID naming system. This attribute is false by default.

forceIdIndex	String

The forceIdIndex attribute effects the component ID name when this component is rendered at runtime. It expects a boolean value that, when true, causes the component to display an index number in its ID value if the component is in a list. It has a default value of true.

hreflang	String

The hreflang attribute identifies the language code of the resource link to by this hyperlink.

id	String

The unique identifier value for this component. The value must be unique within the closest naming container.

immediate	String

The immediate attribute is a boolean flag indicating that component events should be sent to registered event listeners immediately rather than after the validation phase of the JSF request processing lifecycle. The immediate flag allows you bypass JSF validation for a particular component.

lang	String

The lang attribute is a standard HTML attribute that sets the code describing the language to be used in the markup generated by this component.

onblur	String

The onblur attribute sets the JavaScript code to execute when this element loses focus.

onclick	String

onmousemove	String

The onmousemove attribute sets the JavaScript code to execute when the mouse pointer is moved within this element.

onmouseout	String

The onmouseout attribute sets the JavaScript code to execute when the mouse pointer is moved away from this element.

onmouseover	String

The onmouseover attribute sets the JavaScript code to execute when the mouse pointer is moved onto this element.

onmouseup	String

The onmouseup attribute sets the JavaScript code to execute when the mouse button is released over this element.

rel	String

The rel attribute identifies the relationship from the current document to the anchor specified by this hyperlink. The value of this attribute is a space-separated list of link types.

rendered	String

A value-binding expression that evaluates to a Boolean condition indicating if this component should be rendered.

target	String

The target attribute is a standard HTML attribute that instructs the browser on how to open the hyperlink. Valid values are _blank, _self, _parent, and _top. The _blank value indicates that the page should open in a new browser window. The _self value indicates that the link should replace the current page with the linked page. The _parent value will replace the page from which the hyperlink originated. The _top value will replace whatever is loaded in the current browser (eg. frameset).
