public String getTagName()
getTagName
in class AbstractBaseTag
public void setAttribute(String name, String value) throws javax.servlet.jsp.JspException
name
represents
the name of the attribute.
The value
represents the value and may contain
a netui expression. This method may result in errors being generated.
This requires that the tag buffer its body and
write attributes in the end tag. For the textarea tag it is not legal to set
the id
or name
attributes with this method.
setAttribute
in interface IAttributeConsumer
name
- The name of the attribute. This value may not be null or the empty string.value
- The value of the attribute. This may contain a netui expression.
javax.servlet.jsp.JspException
- A JspException may be thrown if there is an error setting the attribute.public String getCols()

- - true or falsepublic boolean getReadonly()
public void setReadonly(boolean readonly)
readonly
- - the read-only statepublic String getRows()
public void setRows(String rows)
rows
- - the number of rowspublic String getTagId()
public void setTagId(String tagId)
tagId
- - the ID.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.
