I have a select list component in Oracle apex and one button
Select list drop down as below values I can choose any one
-
On button click I have written a java script
if $('#P1_DROPDOWN').val() == 'A'
{
alert.message('A value is selected')
}
else
{
apex.item.setvalue(index[0]) -- blank
or
reset the list to none selected
}
How do I reset the List item to none o original state
Here is an example for a select list that has "Display Null Value" set to "Yes" and no value for "Null Return Value".
if (apex.item( "P1_DROPDOWN" ).getValue() == 'A') {
alert('a was clicked');
} else {
apex.item( "P1_DROPDOWN" ).setValue( "" );
}
If there is a return value for the Null value, then change the setValue accordingly.
Side Note: Instead of clearing the selected value a validation indicating why the selected value is not the correct one might give a better user experience.
