示例1: it
it('should get an array of the MIME types contained within the dataset', () => {
let data = new MimeData();
data.setData('foo', 1);
data.setData('bar', '1');
data.setData('baz', { foo: 1, bar: 2 });
expect(data.types()).to.deep.equal(['foo', 'bar', 'baz']);
});示例2: findTextData
export function findTextData(mime: MimeData): string | undefined {
const types = mime.types();
const textType = types.find(t => t.indexOf('text') === 0);
if (textType === undefined) {
return undefined;
}
return mime.getData(textType) as string;
}示例3: copyOrCut
/**
* Copy or cut the selected cell data to a clipboard.
*
* @param widget - The target notebook widget.
