Method Detail

setValueAttribute

public void setValueAttribute(String newValue)

Sets the content of the "value" attribute.

Parameters:

newValue - the new content

doClickAction

protected void doClickAction()
                      throws IOException

This method will be called if there either wasn't an onclick handler, or if there was one, but the result of that handler wasn't false. This is the default behavior of clicking the element.

The default implementation returns the current page. Subclasses requiring different behavior (like HtmlSubmitInput) will override this method.

Overrides:

doClickAction in class HtmlElement

Throws:

IOException - if an IO error occurs

isDisabled

public final boolean isDisabled()

Returns true if the disabled attribute is set for this element.

Specified by:

isDisabled in interface DisabledElement

Returns:

true if the disabled attribute is set for this element

getSubmitKeyValuePairs

public NameValuePair[] getSubmitKeyValuePairs()

Returns an array of NameValuePairs that are the values that will be sent back to the server whenever this element's containing form is submitted.

THIS METHOD IS INTENDED FOR THE USE OF THE FRAMEWORK ONLY AND SHOULD NOT BE USED BY CONSUMERS OF HTMLUNIT. USE AT YOUR OWN RISK.

Specified by:

getSubmitKeyValuePairs in interface SubmittableElement

Returns:

the values that will be sent back to the server whenever this element's containing form is submitted

reset

public void reset()

Returns the value of this element to the default value or checked state (usually what it was at the time the page was loaded, unless it has been modified via JavaScript).

Specified by:

reset in interface SubmittableElement

See Also:

SubmittableElement.reset()

setDefaultValue

public void setDefaultValue(String defaultValue)

Sets the default value to use when this element gets reset, if applicable.

Specified by:

setDefaultValue in interface SubmittableElement

Parameters:

defaultValue - the default value to use when this element gets reset, if applicable

See Also:

SubmittableElement.setDefaultValue(String)

getDefaultValue

public String getDefaultValue()

Returns the default value to use when this element gets reset, if applicable.

Specified by:

getDefaultValue in interface SubmittableElement

Returns:

the default value to use when this element gets reset, if applicable

See Also:

SubmittableElement.getDefaultValue()

setDefaultChecked

public void setDefaultChecked(boolean defaultChecked)

Sets the default checked state to use when this element gets reset, if applicable. This implementation is empty; only checkboxes and radio buttons really care what the default checked value is.

Specified by:

setDefaultChecked in interface SubmittableElement

Parameters:

defaultChecked - the default checked state to use when this element gets reset, if applicable

See Also:

SubmittableElement.setDefaultChecked(boolean), HtmlRadioButtonInput.setDefaultChecked(boolean), HtmlCheckBoxInput.setDefaultChecked(boolean)

isDefaultChecked

public boolean isDefaultChecked()

Returns the default checked state to use when this element gets reset, if applicable. This implementation returns false; only checkboxes and radio buttons really care what the default checked value is.

Specified by:

isDefaultChecked in interface SubmittableElement

Returns:

the default checked state to use when this element gets reset, if applicable

See Also:

SubmittableElement.isDefaultChecked(), HtmlRadioButtonInput.isDefaultChecked(), HtmlCheckBoxInput.isDefaultChecked()

getNameAttribute

public final String getNameAttribute()

Sets the value of the specified attribute. This method may be overridden by subclasses which are interested in specific attribute value changes, but such methods must invoke super.setAttributeValue(), and should consider the value of the cloning parameter when deciding whether or not to execute custom logic.
