问题描述
在表面上使用拖放功能后,我想获得此Surface的确切新位置。我怎样才能做到这一点?
After using drag and drop on a surface I want to get the exact new position of this Surface. How can I do that?
推荐答案
您将能够从您的Draggable修饰符得到结束
事件 draggable.on('end',function(e){var pos = e.position;})
You will be able to get the position from your Draggable modifier on end
event draggable.on('end',function(e){var pos = e.position;})
Here is a link for the following code example:
var mainContext = Engine.createContext();
var transTransform = new TransitionableTransform();
transTransform.set(Transform.translate(100, 0, 0));
var surface = new Surface({
size: [300, 100],
properties: {
backgroundColor: 'rgba(255,0,0,0.1)',
cursor: 'pointer'
}
});
var dragSurface = new Surface({
content: 'Drag Me',
size: [100, 100],
properties: {
backgroundColor: 'rgba(0,0,0,0.1)',
cursor: 'pointer'
}
});
var modifier = new Modifier({
origin: [0, 0],
align: [0, 0],
transform: transTransform
});
var draggable = new Draggable();
draggable.subscribe(dragSurface);
var content = 'Not Draggable';
surface.setContent(content);
mainContext.add(modifier).add(surface);
mainContext.add(draggable).add(dragSurface);
draggable.on('update', function (e) {
var pos = e.position;
surface.setContent('Draggable Position is '+pos);
transTransform.set(Transform.translate(pos[0]+100, pos[1], 0));
})
draggable.on('end', function (e) {
var pos = e.position;
surface.setContent('Draggable End Position is '+pos);
transTransform.set(Transform.translate(pos[0]+100, pos[1], 0));
})
: Modifier.setTransform()
已被弃用。
Note: Modifier.setTransform()
has been deprecated.
