在使用Ant Design Vue时,a-input输入框默认是单向绑定的,即只能通过v-model绑定输入框的值,而无法实现实时更新。如果要实现a-input输入框的双向绑定,可以通过监听input事件来实现。首先,需要给a-input添加一个id属性,例如id="myInput"。然后,在Vue的mounted生命周期钩子函数中,获取到该a-input元素,并通过addEventListener方法监听input事件。当input事件触发时,可以通过event.target.value来获取输入框的值,并将该值赋给Vue实例的data属性中的相应数据。这样就实现了a-input输入框的双向绑定。下面是一个示例代码:
```html
<template>
<div>
<a-input id="myInput" v-model="inputValue"></a-input>
<p>输入的值:{{ inputValue }}</p>
</div>
</template>
<script>
export default {
data() {
return {
inputValue: ''
}
},
mounted() {
const inputEl = document.getElementById('myInput')
inputEl.addEventListener('input', (event) => {
this.inputValue = event.target.value
})
}
}
</script>
```
通过以上代码,你可以实现a-input输入框的双向绑定,输入框中的值会实时更新到Vue实例的data属性中,并可以在模板中显示出来。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
