getOpacity();
The getOpacity method returns opacity value from 0 to 1.
Executing the example requires the ColorCombo component named colCombo (see Example of Creating the ColorCombo Component). Output the value of the current color's transparency to the JavaScript console:
console.log(colCombo.getColor().getOpacity()
After executing the example the browser console displays the transparency value for the current color of the ColorCombo component.
