	this.art.proxy(container, 'click', (event) => {
	updateLeft(event);
	});
	this.art.proxy(container, 'mousedown', (event) => {
	isDroging = event.button === 0;
	});
	this.art.on('document:mousemove', (event) => {
	if (isDroging) {
	updateLeft(event);
	}
	});
	this.art.on('document:mouseup', (event) => {
	if (isDroging) {
	isDroging = false;
	updateLeft(event);
	}
	});

发现只支持了mouse事件，希望能支持下touch事件，方便在移动端拖动
