Tag Attributes

accesskey Text
 
The accesskey attribute is a standard HTML attribute that sets the access key that transfers focus to this element when pressed.
action Text
 
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 Text
 
The actionFor attribute expects a comma-separated list of component IDs associated with the component generating the action event.
actionListener Text
 
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.
alt Text
 
The alt attribute is a standard HTML attribute that sets the alternate textual description rendered by this component.
binding Expression
 
The value-binding expression linking this component tag to a backing bean property.
dir Text
 
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 Text
 
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.
enabledOnUserRole Text
 
The enabledOnUserRole attribute determines if this component will be rendered normally or not depending on the user's roles.
forceId Text
 
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 Text
 
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.
id Text
 
The unique identifier value for this component. The value must be unique within the closest naming container.
image Text
 
The image attribute links a image to the button through a URL.
immediate Text
 
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.
label Text
 
A display name for this component.
lang Text
 
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 Text
 
The onblur attribute sets the JavaScript code to execute when this element loses focus.
onchange Text
 
The onchange attribute sets the JavaScript code to execute when this element loses focus and its value changes after gaining focus.
onclick Text
 
The onclick attribute sets the JavaScript code to execute when the mouse pointer is clicked over this element.
ondblclick Text
 
The ondblclick attribute sets the JavaScript code to execute when the mouse pointer is double-clicked over this element.
onfocus Text
 
The onfocus attribute sets the JavaScript code to execute when the element receives focus.
onkeydown Text
 
The onkeydown attribute sets the JavaScript code to execute when a key is pressed down over this element.
onkeypress Text
 
The onkeypress attribute sets the JavaScript code to execute when a key is pressed and released over this element.
onkeyup Text
 
The onkeyup attribute sets the JavaScript code to execute when a key is released over this element.
onmousedown Text
 
The onmousedown attribute sets the JavaScript code to execute when the mouse pointer is pressed down over this element.
onmousemove Text
 
The onmousemove attribute sets the JavaScript code to execute when the mouse pointer is moved within this element.
onmouseout Text
 
The onmouseout attribute sets the JavaScript code to execute when the mouse pointer is moved away from this element.
onmouseover Text
 
The onmouseover attribute sets the JavaScript code to execute when the mouse pointer is moved onto this element.
onmouseup Text
 
The onmouseup attribute sets the JavaScript code to execute when the mouse button is released over this element.
onselect Text
 
The onselect attribute sets the JavaScript code to execute when the user selects the text contained by this element.
readonly Text
 
HTML:When true, indicates that this component cannot be modified by the user. The element may receive focus unless it has also been disabled.
rendered Text
 
A value-binding expression that evaluates to a Boolean condition indicating if this component should be rendered.
style Text
 
The style attribute sets the CSS style definition to be applied to this component when it is rendered.
styleClass Text
 
The styleClass attribute sets the CSS class to apply to this component when it is rendered.
tabindex Text
 
The tabindex attribute is a standard HTML attribute that sets the order in which this element receives focus when the user cycles through the elements using the TAB key. The value for this attribute must be an integer between 0 and 32767.
title Text
 
The title attribute is a standard HTML attribute that sets the tooltip text to display for the rendered component.
type Text
 
The type attribute specifies the HTML content type associated with the resource pointed to by this hyperlink.
value Text
 
The value attribute sets the current value for this component.
visibleOnUserRole Text
 
The visibleOnUserRole attribute determines if this component will be visible or not depending on the user's roles.
