Vue.js triggerRef()用法及代码示例

function triggerRef(ref: ShallowRef): void

const shallow = shallowRef({
  greet: 'Hello, world'
})

// Logs "Hello, world" once for the first run-through
watchEffect(() => {
  console.log(shallow.value.greet)
})

// This won't trigger the effect because the ref is shallow
shallow.value.greet = 'Hello, universe'

// Logs "Hello, universe"
triggerRef(shallow)
