javascript - 鼠标按下事件未在纸质 js 中触发

Question

没有触发鼠标按下，但其他事件是。

paper.install(window)
paper.setup('canvas')
paper.view.onMouseDown = this.onMouseDown
paper.view.onMouseDrag = this.onMouseDrag
paper.view.onMouseUp = this.onMouseUp

但是，当mouseDown事件在画布中手动注册时，它每次都会被触发。

this.canvasComponent = this.$refs.canvas

this.canvasComponent.onmousedown = function (e) {
  console.log('Down fired')
}
