Element.setOpacity(element, opacity) -> [HTMLElement...]
someElement.setOpacity(opacity) -> [HTMLElement...]

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 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");
