Input 输入
用于对话的输入框组件

按需引入路径:
import { McInput } from '@matechat/core';基本用法
绑定 value 等基本参数进行使用。
<template>
<McInput :value="inputValue" :maxLength="2000" :loading="loading" showCount @change="onInputChange" @submit="onSubmit" @cancel="onCancel">
</McInput>
</template>
<script setup>
import { defineComponent, ref } from 'vue';
const inputValue = ref('');
const loading = ref(false);
const onInputChange = (e) => {
console.log('input change---', e);
};
const onSubmit = (e) => {
loading.value = true;
console.log('input submit---', e);
};
const onCancel = () => {
loading.value = false;
console.log('input cancel');
};
</script>展示形态
通过displayType参数设置展示形态,支持的值为full和simple,默认为full。
full形态,prefix 插槽和输入框在同一行,extra 插槽和发送按钮在下方。
simple形态,prefix 插槽、输入框和发送按钮在同一行,不支持 extra 插槽。
variant参数设置为borderless,可设置不带边框。
通过sendBtnVariant参数控制发送按钮的形态,支持的值为full和simple,默认为full。
<template>
<McInput :value="inputValue" displayType="simple" :loading="loading" sendBtnVariant="simple" variant="borderless" @submit="onSubmit">
<template #suffix>
<div class="input-prefix-wrap">
<i class="icon-appendix"></i>
</div>
</template>
</McInput>
</template>
<script setup>
import { defineComponent, ref } from 'vue';
const inputValue = ref('');
const loading = ref(false);
const onSubmit = (e) => {
loading.value = true;
setTimeout(() => {
loading.value = false;
}, 1000);
console.log('input submit---', e);
};
</script>
<style scoped lang="scss">
.input-prefix-wrap {
height: 32px;
line-height: 32px;
margin-right: 8px;
cursor: pointer;
}
</style>提交模式
通过submitShortKey设置提交快捷键,支持的值为enter和shiftEnter,默认为enter。
当提交快捷键为enter时,换行快捷键为shift+enter;当提交快捷键为shift+enter时,换行快捷键为enter。
<template>
<McInput :value="inputValue" :loading="loading" submitShortKey="shiftEnter" @submit="onSubmit"> </McInput>
</template>
<script setup>
import { defineComponent, ref } from 'vue';
const inputValue = ref('');
const loading = ref(false);
const onSubmit = (e) => {
loading.value = true;
setTimeout(() => {
loading.value = false;
}, 1000);
console.log('input submit---', e);
};
</script>自定义发送按钮
通过button插槽自定义发送按钮,实现按钮 disable、loading 等状态和按钮图标、按钮文案的自定义。
<template>
<McInput :value="inputValue" :maxLength="2000" :loading="loading" showCount @change="onInputChange" @submit="onSubmit" @cancel="onCancel">
<template #button>
<div
class="my-button"
:class="{ 'disabled': !loading && !inputValue}"
@click="onConfirm"
>
<span class="mc-button-content">
<!-- 此处可自定义图标及其文案 -->
<span>{{ loading ? '停止' : '发送' }}</span>
</span>
</div>
</template>
</McInput>
</template>
<script setup>
import { defineComponent, ref } from 'vue';
const inputValue = ref('');
const loading = ref(false);
const onInputChange = (e) => {
inputValue.value = e;
console.log('input change---', e);
};
const onSubmit = (e) => {
loading.value = true;
inputValue.value = '';
setTimeout(() => {
loading.value = false;
}, 1000);
console.log('input submit---', e);
};
const onCancel = () => {
loading.value = false;
console.log('input cancel');
};
const onConfirm = () => {
if(loading.value) {
onCancel();
} else {
onSubmit();
}
}
</script>
<style scoped lang="scss">
.my-button {
display: flex;
align-items: center;
height: 32px;
background: #5e7ce0;
padding: 0 16px;
border-radius: 20px;
color: #fff;
}
.disabled {
background: #beccfa;
}
</style>自动调整高度
通过 autosize 属性让文本域自动调整高度,支持布尔值和配置对象两种形式。
- 设置为
true:使用默认配置(最小1行,最大5行) - 设置为对象:可自定义最小和最大行数,如
{ minRows: 2, maxRows: 10 }
默认自动调整(最小1行,最大5行)
自定义行数范围(最小2行,最大10行)
禁用自动调整
<template>
<div class="autosize-demo">
<h4>默认自动调整(最小1行,最大5行)</h4>
<McInput
:value="inputValue1"
autosize
placeholder="输入多行文本查看自动调整效果..."
@change="onChange1"
/>
<h4>自定义行数范围(最小2行,最大10行)</h4>
<McInput
:value="inputValue2"
:autosize="{ minRows: 2, maxRows: 10 }"
placeholder="输入多行文本查看自定义行数效果..."
@change="onChange2"
/>
<h4>禁用自动调整</h4>
<McInput
:value="inputValue3"
:autosize="false"
placeholder="固定高度的文本域"
@change="onChange3"
/>
</div>
</template>
<script setup>
import { ref } from 'vue';
const inputValue1 = ref('');
const inputValue2 = ref('');
const inputValue3 = ref('');
const onChange1 = (e) => {
inputValue1.value = e;
};
const onChange2 = (e) => {
inputValue2.value = e;
};
const onChange3 = (e) => {
inputValue3.value = e;
};
</script>
<style scoped lang="scss">
.autosize-demo {
h4 {
margin: 20px 0 10px;
color: var(--devui-text);
font-size: 14px;
}
}
</style>自动聚焦
通过 autofocus 属性设置输入框在组件挂载后自动获得焦点,默认为 false。当输入框被禁用时,自动聚焦不会生效。
<template>
<McInput :value="inputValue" autofocus :loading="loading" @change="onInputChange" @submit="onSubmit" @cancel="onCancel">
</McInput>
</template>
<script setup>
import { defineComponent, ref } from 'vue';
const inputValue = ref('');
const loading = ref(false);
const onInputChange = (e) => {
inputValue.value = e;
console.log('input change---', e);
};
const onSubmit = (e) => {
loading.value = true;
inputValue.value = '';
setTimeout(() => {
loading.value = false;
}, 1000);
console.log('input submit---', e);
};
const onCancel = () => {
loading.value = false;
console.log('input cancel');
};
</script>提交时不自动清空输入
通过 autoClear 属性设置输入框在提交后是否自动清空内容,默认为 true。 可以通过 clearInput 方法手动清空输入框内容。
<template>
<McInput ref="mcInputRef" :value="inputValue" :autoClear="false" :loading="loading" @submit="onSubmit" @cancel="onCancel">
</McInput>
</template>
<script setup>
import { defineComponent, ref } from 'vue';
const mcInputRef = ref();
const inputValue = ref('');
const loading = ref(false);
const onSubmit = (e) => {
loading.value = true;
setTimeout(() => {
// 发送成功后手动清空输入框内容
mcInputRef.value.clearInput();
loading.value = false;
}, 1000);
console.log('input submit---', e);
};
const onCancel = () => {
loading.value = false;
console.log('input cancel');
};
</script>插入主题标签
通过 ThemeTagItem 类型配置前置主题标签,支持自定义主题标签的文本内容、pop弹出提示内容等。 当前仅支持最多设置一个ThemeTag,且必须放在 formatContent 数组的第一个位置。 可通过 themeTag 插槽自定义主题标签的展示效果。
<template>
<div class="button-wrapper">
<d-button @click="openThemeTag" style="margin-right: 8px;">插入主题标签</d-button> <d-button @click="closeThemeTag">关闭主题标签</d-button>
</div>
<McInput :formatContentOptions="formatContentOptions" @change="onInputChange" @submit="onSubmit">
