Generates a single HTML checkbox.
Generates a single HTML checkbox. The <netui:checkBox> tag should be used on its own, not within a
<netui:checkBoxGroup>
.
The <netui:checkBox> tag can be data bound to a boolean or Boolean type. For instance,
the following <netui:checkBox> tag...
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 |
alt |
Required: No | Supports
runtime evaluation: Yes | Data bindable: |
|
The alt attribute of the element. |
dataSource |
Required: Yes | Supports
runtime evaluation: No | Data bindable: |
|
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 |
Required: No | Supports
runtime evaluation: Yes | Data bindable: |
|
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. |

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. |
title |
Required: No | Supports
runtime evaluation: Yes | Data bindable: No |
|
The title. |
In this sample, the <netui:checkBox reads it initial value from the
Form Bean field wantSpecialOffers
. Upon submission, the user specified value is
loaded into the same Form Bean field. The data is submitted to the
action method processData
.
