Method Details
-
getForm
HTMLFormElement getForm()Returns theFORM
element containing this control. Returnsnull
if this control is not within the context of a form. -
getDefaultSelected
boolean getDefaultSelected()Represents the value of the HTML selected attribute. The value of this attribute does not change if the state of the corresponding form control, in an interactive user agent, changes. ChangingdefaultSelected
, however, resets the state of the form control. See the selected attribute definition in HTML 4.0. -
setDefaultSelected
void setDefaultSelected(boolean defaultSelected) -
getText
String getText()The text contained within the option element. -
getIndex
int getIndex()The index of thisOPTION
in its parentSELECT
, starting from 0. -
getDisabled
boolean getDisabled()The control is unavailable in this context. See the disabled attribute definition in HTML 4.0. -
setDisabled
void setDisabled(boolean disabled) -
getLabel
String getLabel()Option label for use in hierarchical menus. See the label attribute definition in HTML 4.0. -
setLabel
-
getSelected
boolean getSelected()Represents the current state of the corresponding form control, in an interactive user agent. Changing this attribute changes the state of the form control, but does not change the value of the HTML selected attribute of the element. -
setSelected
void setSelected(boolean selected) -
getValue
String getValue()The current form control value. See the value attribute definition in HTML 4.0. -
setValue
