JavaScript

If the <netui:imageButton> specifies a rolloverImage attribute, the following JavaScript will be written to the page:

    function swapImage(control, image)
    {
        control.src = image;
    }

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.

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

The tabIndex of the rendered HTML tag. This attribute determines the position of the rendered HTML tag in the sequence of tags 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.

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

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

The value of the image button.

 
Example

In this sample, an <netui:imageButton> tag displays the image "house.jpg". On mouseover, the image "house_highlight.jpg" is displayed. When clicked, the <netui:imageButton> will invoke the action specified by its parent <netui:form> tag.

    <netui:form action="formSubmit">
         <netui:imageButton rolloverImage="house_highlight.jpg" src="house.jpg" />
     </netui:form>
