示例

此示例设置动画效果的持续时间。

const presentation = Api.GetPresentation();
const slide = presentation.GetSlideByIndex(0);

const shape = Api.CreateShape(
	'rect',
	150 * 36000, 100 * 36000,
	Api.CreateSolidFill(Api.CreateRGBColor(61, 74, 107)),
	Api.CreateStroke(0, Api.CreateNoFill())
);
shape.SetPosition(100 * 36000, 80 * 36000);
slide.AddObject(shape);

const timeLine = slide.GetTimeLine();
const mainSequence = timeLine.GetMainSequence();
const effect = mainSequence.AddEffect(shape, 'entranceFade', 'onclick');

// Set duration to 2 seconds
effect.SetDuration(2000);
const duration = effect.GetDuration();

const infoShape = Api.CreateShape(
	'rect',
	150 * 36000, 40 * 36000,
	Api.CreateSolidFill(Api.CreateRGBColor(200, 200, 200)),
	Api.CreateStroke(0, Api.CreateNoFill())
);
infoShape.SetPosition(20 * 36000, 10 * 36000);
const content = infoShape.GetDocContent();
const paragraph = content.GetElement(0);
paragraph.AddText('New duration: ' + duration + 'ms (2 seconds)');
slide.AddObject(infoShape);
