Description

Renders an HTML <input type="text"> tag.

Attributes

accessKeyThe 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
 
RequiredSupports runtime expression evaluationData bindable
NoNoNo

altThe alt attribute of the element.

NoNoRead Only

dataSource

The dataSource attribute determines both (1) the source of populating data for the tag and (2) the object to which the tag submits data.

For example, assume that the Controller file (= JPF file) contains a Form Bean with the property foo. Then the following <netui:textBox> tag will (1) draw populating data from the Form Bean's foo property and (2) submit user defined data to the same property.

    <netui:textBox dataSource="{actionForm.foo}" />

The dataSource attribute takes either a data binding expression or the name of a Form Bean property. In the above example, <netui:textBox dataSource="foo" /> would have the exactly same behavior.

When the tag is used to submit data, the data binding expression must refer to a Form Bean property. In cases where the tag is not used to submit data, but is used for displaying data only, the data binding expression need not refer to a Form Bean property. For example, assume that myIterativeData is a member variable on the Controller file ( = JPF file). The following <netui-data:repeater> tag draws its data from myIterativeData.

    <netui-data:repeater dataSource="{pageFlow.myIterativeData}">

defaultValue

Use in <netui:checkBoxGroup>, <netui:checkBox>, <netui:radioButtonGroup>, and <netui:select> tags

Sets the preselected value or values.

The defaultValue attribute takes either a String literal or a data binding expression.

If the defaultValue attribute has a String value (or if the data binding expression points to a String), then a single value will be preselected.

If the defaultValue attribute points to a String[] object (or any object which can be iterated over), then multiple values will be preselected.

Use in <netui:textArea> and <netui:textBox> tags

Sets the initial display text.

The defaultValue attribute takes either a String literal or a data binding expression that points to a String.

tagId

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.

Sample

In this sample, a <netui:textBox> reads from and writes to the Form Bean's firstname property. If the submitted text is NULL, the default value is specified by the Page Flow's firstName property.
     <netui:textBox dataSource="{actionForm.firstName}"
           defaultValue="{pageFlow.defaultFirstName}"
           size="20" />
