Method Detail

getTagName

public String getTagName() Return the name of the Tag.

Specified by:getTagName in class AbstractBaseTag

setAttribute

public void setAttribute(String name, String value) throws javax.servlet.jsp.JspException Set an attribute value. The 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.

Specified by:setAttribute in interface IAttributeConsumer Parameters: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. Throws: javax.servlet.jsp.JspException - A JspException may be thrown if there is an error setting the attribute.

public String getMaxlength() Gets the maximum length (in characters) of the TextBox.

Returns:the max length

setMaxlength

public void setMaxlength(String maxlength) Set the maximum length (in characters) of the TextBox.

public boolean getPassword() Gets the password state (true means this is a password field).

Returns:the password state

setPassword

public void setPassword(boolean password) Set the password state (true means this is a password field).

Parameters:password - - the password stateBeadoc.attributedescription: Boolean. Determines whether the password characters that the user enters into the <input> element will be disguised in the browser. Beadoc.attributesyntaxvalue: boolean_password Beadoc.databindable: false

getDisabled

public String getDisabled() Gets if this TextBox is disabled or not.

Returns:the disabled state (true or false)

setDisabled

public void setDisabled(String disabled) Set if this TexBox is disabled or not.

Parameters:disabled - - true or falseBeadoc.attributedescription: Boolean. Determines if the rendered <input> element is disabled. Beadoc.attributesyntaxvalue: boolean_disabled Beadoc.databindable: Read Only

getReadonly

public boolean getReadonly() Gets if this TextBox is read-only.

Returns:the read-only state

setReadonly

public void setReadonly(boolean readonly) Set if this TextBox is read-only.

Parameters:readonly - - the read-only stateBeadoc.attributedescription: Boolean. Determines if the rendered <input> element is read-only. Beadoc.attributesyntaxvalue: boolean_readOnly Beadoc.databindable: false

getSize

getTagId

public String getTagId() Return the ID of the textbox.

Returns:the ID.

setTagId

public void setTagId(String tagId) Set the ID of the textbox.

Parameters:tagId - - the ID.Beadoc.attributedescription:

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.
