Vben Alert 轻量提示框
Alert 提供了一组纯 JavaScript 调用的轻量提示框能力,适合快速创建 alert、confirm、prompt 这类简单交互。
适用场景
Alert 与 Modal 的能力有部分重叠,但更适合临时确认、简单提示和轻量输入场景。复杂弹窗仍然建议使用 Vben Modal。:::
注意
通过 alert、confirm、prompt 动态创建的弹窗,在已经打开的情况下不支持 HMR 热更新。修改相关代码后,需要关闭后重新打开。:::
基础用法
使用 alert 创建只有确认按钮的提示框。
vue
<script lang="ts" setup>
import { h } from 'vue';
import { alert, VbenButton } from '@vben/common-ui';
import { Result } from 'ant-design-vue';
function showAlert() {
alert('This is an alert message');
}
function showIconAlert() {
alert({
content: 'This is an alert message with icon',
icon: 'success',
});
}
function showCustomAlert() {
alert({
buttonAlign: 'center',
content: h(Result, {
status: 'success',
subTitle: '已成功创建订单。订单ID:2017182818828182881',
title: '操作成功',
}),
});
}
</script>
<template>
<div class="flex gap-4">
<VbenButton @click="showAlert">Alert</VbenButton>
<VbenButton @click="showIconAlert">Alert With Icon</VbenButton>
<VbenButton @click="showCustomAlert">Alert With Custom Content</VbenButton>
</div>
</template>使用 confirm 创建带确认和取消按钮的提示框。
vue
<script lang="ts" setup>
import { h, ref } from 'vue';
import { alert, confirm, VbenButton } from '@vben/common-ui';
import { Checkbox, message } from 'ant-design-vue';
function showConfirm() {
confirm('This is an alert message')
.then(() => {
alert('Confirmed');
})
.catch(() => {
alert('Canceled');
});
}
function showIconConfirm() {
confirm({
content: 'This is an alert message with icon',
icon: 'success',
});
}
function showfooterConfirm() {
const checked = ref(false);
confirm({
cancelText: '不要虾扯蛋',
confirmText: '是的,我们都是NPC',
content:
'刚才发生的事情,为什么我似乎早就经历过一般?\n我甚至能在事情发生过程中潜意识里预知到接下来会发生什么。\n\n听起来挺玄乎的,你有过这种感觉吗?',
footer: () =>
h(
Checkbox,
{
checked: checked.value,
class: 'flex-1',
'onUpdate:checked': (v) => (checked.value = v),
},
'不再提示',
),
icon: 'question',
title: '未解之谜',
}).then(() => {
if (checked.value) {
message.success('我不会再拿这个问题烦你了');
} else {
message.info('下次还要继续问你哟');
}
});
}
function showAsyncConfirm() {
confirm({
beforeClose({ isConfirm }) {
if (isConfirm) {
// 这里可以执行一些异步操作。如果最终返回了false,将阻止关闭弹窗
return new Promise((resolve) => setTimeout(resolve, 2000));
}
},
content: 'This is an alert message with async confirm',
icon: 'success',
}).then(() => {
alert('Confirmed');
});
}
</script>
<template>
<div class="flex gap-4">
<VbenButton @click="showConfirm">Confirm</VbenButton>
<VbenButton @click="showIconConfirm">Confirm With Icon</VbenButton>
<VbenButton @click="showfooterConfirm">Confirm With Footer</VbenButton>
<VbenButton @click="showAsyncConfirm">Async Confirm</VbenButton>
</div>
</template>使用 prompt 创建可接收用户输入的提示框。
vue
<script lang="ts" setup>
import { h } from 'vue';
import { alert, prompt, useAlertContext, VbenButton } from '@vben/common-ui';
import { Input, RadioGroup, Select } from 'ant-design-vue';
import { BadgeJapaneseYen } from 'lucide-vue-next';
function showPrompt() {
prompt({
content: '请输入一些东西',
})
.then((val) => {
alert(`已收到你的输入:${val}`);
})
.catch(() => {
alert('Canceled');
});
}
function showSlotsPrompt() {
prompt({
component: () => {
// 获取弹窗上下文。注意:只能在setup或者函数式组件中调用
const { doConfirm } = useAlertContext();
return h(
Input,
{
onKeydown(e: KeyboardEvent) {
if (e.key === 'Enter') {
e.preventDefault();
// 调用弹窗提供的确认方法
doConfirm();
}
},
placeholder: '请输入',
prefix: '充值金额:',
type: 'number',
},
{
addonAfter: () => h(BadgeJapaneseYen),
},
);
},
content:
'此弹窗演示了如何使用自定义插槽,并且可以使用useAlertContext获取到弹窗的上下文。\n在输入框中按下回车键会触发确认操作。',
icon: 'question',
modelPropName: 'value',
}).then((val) => {
if (val) alert(`你输入的是${val}`);
});
}
function showSelectPrompt() {
prompt({
component: Select,
componentProps: {
options: [
{ label: 'Option A', value: 'Option A' },
{ label: 'Option B', value: 'Option B' },
{ label: 'Option C', value: 'Option C' },
],
placeholder: '请选择',
// 弹窗会设置body的pointer-events为none,这回影响下拉框的点击事件
popupClassName: 'pointer-events-auto',
},
content: '此弹窗演示了如何使用component传递自定义组件',
icon: 'question',
modelPropName: 'value',
}).then((val) => {
if (val) {
alert(`你选择了${val}`);
}
});
}
function sleep(ms: number) {
return new Promise((resolve) => setTimeout(resolve, ms));
}
function showAsyncPrompt() {
prompt({
async beforeClose(scope) {
if (scope.isConfirm) {
if (scope.value) {
// 模拟异步操作,如果不成功,可以返回false
await sleep(2000);
} else {
alert('请选择一个选项');
return false;
}
}
},
component: RadioGroup,
componentProps: {
class: 'flex flex-col',
options: [
{ label: 'Option 1', value: 'option1' },
{ label: 'Option 2', value: 'option2' },
{ label: 'Option 3', value: 'option3' },
],
},
content: '选择一个选项后再点击[确认]',
icon: 'question',
modelPropName: 'value',
}).then((val) => {
alert(`${val} 已设置。`);
});
}
</script>
<template>
<div class="flex gap-4">
<VbenButton @click="showPrompt">Prompt</VbenButton>
<VbenButton @click="showSlotsPrompt"> Prompt With slots </VbenButton>
<VbenButton @click="showSelectPrompt">Prompt With Select</VbenButton>
<VbenButton @click="showAsyncPrompt">Prompt With Async</VbenButton>
</div>
</template>useAlertContext
当 content、footer 或 icon 使用的是自定义组件时,可以在这些组件内部通过 useAlertContext() 获取当前弹窗上下文,并主动触发确认或取消。
注意
useAlertContext 只能在 setup 或函数式组件中使用。:::
