Vue3 useVModels useVModel 的使用

简化了 emit 的操作

import { useVModels } from '@vueuse/core'

export default {
  props: {
    foo: String,
    bar: Number,
  },
  setup(props, { emit }) {
    const { foo, bar } = useVModels(props, emit)

    console.log(foo.value) // props.foo
    foo.value = 'foo' // emit('update:foo', 'foo')
  },
}

<script lang="ts" setup>
import { useVModel } from '@vueuse/core'

const props = defineProps<{
  modelValue: string
}>()
const emit = defineEmits(['update:modelValue'])

const data = useVModel(props, 'modelValue', emit)
</script>
