感谢您的提问!以下是 Taro Ui Vue3 中 AtFloatLayout 组件的一个例子,可以在弹出输入框时禁止页面滚动:
```
<template>
<div>
<AtButton type="primary" @click="toggleFloatLayout">弹出浮动层</AtButton>
<AtFloatLayout :isOpened="isOpened" @close="handleClose">
<div class="input-wrapper">
<input type="text" placeholder="请输入内容" @focus="handleFocus" @blur="handleBlur">
</div>
</AtFloatLayout>
</div>
</template>
<script>
import { defineComponent, onMounted, ref } from 'vue'
import { AtButton, AtFloatLayout } from 'taro-ui-vue3'
export default defineComponent({
name: 'FloatLayoutExample',
components: {
AtButton,
AtFloatLayout,
},
setup() {
const isOpened = ref(false)
const toggleFloatLayout = () => {
isOpened.value = !isOpened.value
}
const handleClose = () => {
isOpened.value = false
}
const handleFocus = () => {
document.body.style.overflow = 'hidden'
}
const handleBlur = () => {
document.body.style.overflow = 'auto'
}
onMounted(() => {
document.body.style.height = '100%'
})
return {
isOpened,
toggleFloatLayout,
handleClose,
handleFocus,
handleBlur,
}
},
})
</script>
<style scoped>
.input-wrapper {
padding: 20px;
}
input {
width: 100%;
height: 50px;
font-size: 18px;
border: none;
border-bottom: 1px solid #ccc;
outline: none;
}
</style>
```
这个例子中,我们通过监听输入框的 focus 和 blur 事件,在输入框获得焦点时禁止页面滚动,在失去焦点时恢复页面滚动。同时,在组件挂载时,我们将 body 的高度设置为 100%,以防止页面出现滚动条。希望这个例子能够帮到您!
