  • 修改 text 官方提供了attr方法：
rect.attr('label/text', 'hello')
 
// 等同于
rect.attr('label', {
  text: 'hello',
})
 
// 等同于
rect.attr({
  label: {
    text: 'hello',
  },
})

只要将上面的rect换成node1，我们就可以轻松的修改成功。

  1. 比如说要修改x,y的值？
node.setProp('position', { x: 600, y: 30 });

以上是修改位置的，发现很好用吧。

  1. 当然尺寸也是一样：
node.setProp('size', { width: 600, height: 30 });

我们也可以resize来修改：

node.resize(100,100)
