                    // ... canvas be created
                    // this.suckerCanvas = canvas
                    // this.suckerArea = [x1, y1, x2, y2]
                } else {
                    // this.suckerCanvas && this.suckerCanvas.remove
                }
            }
        }
    }
</script>

Options

color is one-way data flow, so you can't use v-model. why? because you'll listen changeColor event do more things, so i think it's not necessary here.

Events

if you want use sucker, then openSucker, sucker-hide, sucker-canvas, sucker-area is necessary. when you click sucker button, you can click it again or press key of esc to exit.
