instance method Element#setOpacity
Element#setOpacity(opacity) → [Element…]
Sets the visual opacity of an element while working around inconsistencies
in various browsers. The opacity
argument should be a floating point
number, where the value of 0
is fully transparent and 1
is fully opaque.
Element.setStyle
method uses Element.setOpacity
internally when needed.
Examples
var element = $('myelement');
// set to 50% transparency
element.setOpacity(0.5);
// these are equivalent, but allow for setting more than
// one CSS property at once:
element.setStyle({ opacity: 0.5 });
element.setStyle("opacity: 0.5");
This method can be called either as an instance method or as a generic method. If calling as a generic, pass the instance in as the first argument.
