要将文本发送到大屏,您可以使用Vue.js 3中的Props和emit来实现。以下是一个简单的示例:
在大屏组件中,定义一个props接收文本数据:
```
<template>
<div>
<h1>{{ text }}</h1>
</div>
</template>
<script>
export default {
props: {
text: {
type: String,
required: true
}
}
}
</script>
```
在发送文本的组件中,使用emit将文本发送到大屏组件:
```
<template>
<div>
<input v-model="inputText" />
<button @click="sendText">Send Text</button>
</div>
</template>
<script>
export default {
data() {
return {
inputText: ''
}
},
methods: {
sendText() {
this.$emit('text-updated', this.inputText)
}
}
}
</script>
```
在父组件中,将大屏组件和发送文本的组件组合在一起,并监听text-updated事件来更新大屏组件的文本:
```
<template>
<div>
<big-screen :text="displayText" />
<send-text @text-updated="updateDisplayText" />
</div>
</template>
<script>
import BigScreen from './BigScreen.vue'
import SendText from './SendText.vue'
export default {
components: {
BigScreen,
SendText
},
data() {
return {
displayText: ''
}
},
methods: {
updateDisplayText(text) {
this.displayText = text
}
}
}
</script>
```
这样就可以将文本发送到大屏并即时更新了。
