Attributes
defaultValue
Required: No  |   Type: Object  |   Supports runtime evaluation / JSP Expression Language: Yes

The String literal or expression to be used as the default output. If the default value is an expression all formatters will be applied, otherwise the default value will be output without being formatted.
dir
Required: No  |   Type: String  |   Supports runtime evaluation / JSP Expression Language: Yes

Specifies the direction of text. (LTR | RTL)
escapeWhiteSpaceForHtml
Required: No  |   Type: boolean  |   Supports runtime evaluation / JSP Expression Language: Yes

Sets a boolean flag indicating if we will escape white space for HTML.
for
Required: No  |   Type: String  |   Supports runtime evaluation / JSP Expression Language: Yes

The value of this attribute matches a tagId on an form input and links the value to that control.
formatDefaultValue
Required: No  |   Type: String  |   Supports runtime evaluation / JSP Expression Language: Yes

Boolean indicating whether the formatter should be applied to the defaultValue. The default is "false" meaning formatters will not be applied.
lang
Required: No  |   Type: String  |   Supports runtime evaluation / JSP Expression Language: Yes

Sets the language code for the base language of an element's attribute values and text content.
onClick
Required: No  |   Type: String  |   Supports runtime evaluation / JSP Expression Language: Yes

The onClick JavaScript event.
onDblClick
Required: No  |   Type: String  |   Supports runtime evaluation / JSP Expression Language: Yes

The onDblClick JavaScript event.
onKeyDown
Required: No  |   Type: String  |   Supports runtime evaluation / JSP Expression Language: Yes

The onKeyDown JavaScript event.
onKeyPress
Required: No  |   Type: String  |   Supports runtime evaluation / JSP Expression Language: Yes

The onKeyPress JavaScript event.
onKeyUp
Required: No  |   Type: String  |   Supports runtime evaluation / JSP Expression Language: Yes

The onKeyUp JavaScript event.
onMouseDown
Required: No  |   Type: String  |   Supports runtime evaluation / JSP Expression Language: Yes

The onMouseDown JavaScript event.
onMouseMove
Required: No  |   Type: String  |   Supports runtime evaluation / JSP Expression Language: Yes

The onMouseMove JavaScript event.
onMouseOut
Required: No  |   Type: String  |   Supports runtime evaluation / JSP Expression Language: Yes

The onMouseOut JavaScript event.
onMouseOver
Required: No  |   Type: String  |   Supports runtime evaluation / JSP Expression Language: Yes

The onMouseOver JavaScript event.
onMouseUp
Required: No  |   Type: String  |   Supports runtime evaluation / JSP Expression Language: Yes

The onMouseUp JavaScript event.
style
Required: No  |   Type: String  |   Supports runtime evaluation / JSP Expression Language: Yes

Specifies style information for the current element.
styleClass
Required: No  |   Type: String  |   Supports runtime evaluation / JSP Expression Language: Yes

The style class (a style sheet selector).
tagId
Required: No  |   Type: String  |   Supports runtime evaluation / JSP Expression Language: Yes

String value. Sets the id (or name) attribute of the rendered HTML tag. Note that the real id attribute rendered in the browser may be changed by the application container (for example, Portal containers may change the rendered id value to ensure the uniqueness of id's on the page). In this case, the real id rendered in the browser may be looked up through the JavaScript function lookupIdByTagId( tagId, tag ).

For example, assume that some tag's tagId attribute is set to foo.

    <netui:textBox tagId="foo" />

Then the following JavaScript function will return the real id attribute rendered in the browser:

    lookupIdByTagId( "foo", this )

To get a <netui:form> element and all of its children elements in JavaScript, use the same JavaScript function lookupIdByTagId( tagId, tag ). For example, assume that there is a <netui:form> whose tagId attribute is set to bar.

    <netui:form tagId="bar" >

Then the following JavaScript function will return the <netui:form> element and its children (packaged as an array).

    document[lookupIdByTagId( "bar", this )]

To retreive the value entered into a <netui:textBox> within the <netui:form> tag, use the following JavaScript expression.

    document[lookupIdByTagId("bar", this)][lookupIdByTagId("foo", this)].value

The second parameter ensures that the JavaScript function begins its search within the correct Portlet scope. Pass the JavaScript keyword this as the second parameter.

title
Required: No  |   Type: String  |   Supports runtime evaluation / JSP Expression Language: Yes

The title.
value
Required: Yes  |   Type: Object  |   Supports runtime evaluation / JSP Expression Language: Yes

The String literal or expression used as the text of the Label.
