vue封装基础input组件（添加防抖功能）

先看一下效果：

// 调用页面
<template><div><!-- v-model：伪双向绑定   --><my-input v-model="inputVal" label="姓名" type="textarea" /></div>
</template><script>
import MyInput from './MyInput.vue'
export default {name: 'index',data () {return {inputVal: '111'}},components: {MyInput},watch: {inputVal (newVal, oldVal) {// console.log('新旧值', { newVal, oldVal })this.getDataByInputVal()}},created () {this.getDataByInputVal = this.debounce(this.getDataByInputVal, 1000)},methods: {debounce (fn, wait = 500) {let timer = nullreturn function () {timer && clearTimeout(timer)timer = setTimeout(() => {console.log('防抖执行了')fn()}, wait)}},getDataByInputVal () {setTimeout(() => {console.log(this.inputVal)}, 1000)}}
}
</script><style scoped></style>

// my-input组件
<template><div class="my-input"><label>{{ label }}</label><inputv-bind="$attrs"@input="$emit('input', $event.target.value)"/></div>
</template><script>
export default {name: 'MyInput',props: {label: {type: String,required: false}}
}
</script><style scoped></style>
