Description

Renders an HTML button with the specified attributes. To submit data or invoke a method on the Controller file, the <netui:button> tag must a parent <netui:form> tag. The action attribute on the <netui:button> is for the purpose of overriding the action attribute on the enclosing <netui:form> tag. If no action attribute is specified on the <netui:button> tag, the action attribute on the <netui:form> tag will determine which action method is invoked.

Attributes
accessKey
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable: No

The keyboard navigation key for the element. The following values are not recommended because they are often used by browsers: A, C, E, F, G, H, V, left arrow, and right arrow

Required: No  |   Supports runtime evaluation: Yes  |   Data bindable: Yes

Boolean. If disableSecondClick is set to true, the button will disable itself before submitting.
disabled
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable:

lang
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable: No

The lang.
onBlur
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable:

onChange
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable:

onClick
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable: No

The onClick JavaScript event.
onDblClick
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable: No

The onDblClick JavaScript event.
onFocus
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable:

onKeyDown
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable: No

The onKeyDown JavaScript event.
onKeyPress
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable: No

The onKeyPress JavaScript event.
onKeyUp
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable: No

The onKeyUp JavaScript event.
onMouseDown
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable: No

The onMouseDown JavaScript event.
onMouseMove
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable: No

The onMouseMove JavaScript event.
onMouseOut
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable: No

The onMouseOut JavaScript event.
onMouseOver
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable: No

The onMouseOver JavaScript event.
onMouseUp
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable: No

The onMouseUp JavaScript event.
onSelect
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable:

popup
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable: Yes

Boolean. If popup is set to true, the button will open a popup window.
style
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable: No

The style.
styleClass
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable: No

The style class.
tabindex
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable: No

The tabIndex of the rendered HTML tag. This attribute determines the position of the tag in the sequence of page elements that the user may advance through by pressing the TAB key.
tagId
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable: No

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 getNetuiTagName( 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:

    getNetuiTagName( "foo", this )

To get a <netui:form> element and all of its children elements in JavaScript, use the same JavaScript function getNetuiTagName( 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[getNetuiTagName( "bar", this )]

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

    document[getNetuiTagName("bar", this)][getNetuiTagName("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. For detailed information on using the function getNetuiTagName( tagId, tag ) see Using JavaScript in Page Flow and Portal Applications.

targetScope
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable: Yes

The target scope in which the associated action's page flow resides.
title
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable: No

The title.
type
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable: No

The type of the button. Possible values are submit, button, or reset. The default value is submit.
value
Required: No  |   Supports runtime evaluation: Yes  |   Data bindable:

The text displayed by the rendered HTML button.

 
Example

In this sample, the <netui:button> submits data to the Controller file's processData action method (specified on the <netui:form>'s action attribute).

     <netui:form action="processData">
        <!--
        input elements here
        -->
        <netui:button value="Submit" type="submit"/>
     </netui:form>
