Vue.js effectScope()用法及代码示例

function effectScope(detached?: boolean): EffectScope

interface EffectScope {
  run<T>(fn: () => T): T | undefined // undefined if scope is inactive
  stop(): void
}

const scope = effectScope()

scope.run(() => {
  const doubled = computed(() => counter.value * 2)

  watch(doubled, () => console.log(doubled.value))

  watchEffect(() => console.log('Count: ', doubled.value))
})

// to dispose all effects in the scope
scope.stop()
