为什么Kinetic.js中没有'positionChange'事件？

Question

I am trying to do some AngularJS directive with KineticJS. I want a draggable joystick which is a circle in a kinetic canvas, i now want to add a event listener, which should work for touch and mouse. I started trying touchmove but that did not work for mouse.

So i took a look at the Object and i realized i can register xChange and i can do the same for yChange , but why is there no Listener for a positionChange ? Of course i can register two handlers, but i fear this creates a ton of function calls.

Answer 1

基本上我可以使用dragmove因为对象是可拖动的，并且此功能适用于触摸和鼠标
