1. Use parent-child components to pass values
parent component:
<template>
<div>
<a-button style="margin: 20px" type="primary" @click="showModal">上线</a-button>
<OnlineModal :controlVisible="visibleIt" @closeModal="visibleIt=false"/>
</div>
</template>
<script lang="ts">
import { defineComponent, ref } from 'vue'
import { useRoute } from 'vue-router'
import OnlineModal from './onlineModal.vue'
export default defineComponent({
components: {
OnlineModal
},
setup() {
const route = useRoute()
const visibleIt = ref<boolean>(false)
const showModal = () => {
visibleIt.value = true
}
return {
route,
visibleIt,
showModal
}
}
})
</script>
Subassembly:
<template>
<a-modal :visible="controlVisible" title="发布上线" @ok="handleOk" @cancel="handleCancel">
<template #footer>
<a-button key="back" @click="handleCancel">取消</a-button>
<a-button key="submit" type="primary" :loading="loading" @click="handleOk">确认发布</a-button>
</template>
<h1>注意事项</h1>
<ol style=" listStyleType: 'decimal', paddingLeft: 12, marginTop: 10 ">
<li>上线时间：19:00-23:00禁止（流量高峰），紧急上线联系开发。</li>
<li>上线间隔：3分钟内只能上线一次，防止新内容过多时执行慢。</li>
<li>上线成功：出现“上线成功”弹窗，即完成本次上线。</li>
<li>上线频率：少量多次，请勿积攒过多新内容，以免影响用户流量。</li>
</ol>
</a-modal>
</template>
<script lang="ts">
import { ref } from 'vue'
import {postRelease} from '@/services/online'
import { message } from 'ant-design-vue';
export default ({
props:['controlVisible'],
setup(props, {emit}) {
console.log(props.controlVisible);
const loading = ref<boolean>(false)
const handleOk = () => {
loading.value = true
postRelease().then( res => {
console.log(res, '----');
debugger
message.success('上线成功')
loading.value = false
}).catch(err => {
message.error({
title: '错误提示',
content: err?.response?.data?.msg || '上线失败'
})
loading.value = false
})
emit('closeModal')
}
const handleCancel = () => {
emit('closeModal')
}
return {
loading,
handleOk,
handleCancel
}
}
})
</script>
2. Use ref
parent component:
<template>
<div>
<a-button style="margin: 20px" type="primary" @click="showModal">上线</a-button>
<OnlineModal ref="onlineModal" />
</div>
</template>
<script lang="ts">
import { defineComponent, ref } from 'vue'
import { useRoute } from 'vue-router'
import OnlineModal from './onlineModal.vue'
export default defineComponent({
components: {
OnlineModal
},
setup() {
const route = useRoute()
const onlineModal = ref<boolean>(false)
const showModal = () => {
onlineModal.value.openModal()
}
return {
route,
showModal,
onlineModal
}
}
})
</script>
Subassembly:
<template>
<a-modal :visible="controlVisible" title="发布上线" @ok="openModal" @cancel="handleCancel">
<template #footer>
<a-button key="back" @click="handleCancel">取消</a-button>
<a-button key="submit" type="primary" :loading="loading" @click="handleOk">确认发布</a-button>
</template>
<h1>注意事项</h1>
<ol style=" listStyleType: 'decimal', paddingLeft: 12, marginTop: 10 ">

<li>上线间隔：3分钟内只能上线一次，防止新内容过多时执行慢。</li>
<li>上线成功：出现“上线成功”弹窗，即完成本次上线。</li>
<li>上线频率：少量多次，请勿积攒过多新内容，以免影响用户流量。</li>
</ol>
</a-modal>
</template>
<script lang="ts">
import { ref } from 'vue'
import {postRelease} from '@/services/online'
import { message } from 'ant-design-vue';
export default ({
setup(props, {emit}) {
const controlVisible = ref<boolean>(false)
const loading = ref<boolean>(false)
const openModal = () =>{
controlVisible.value = true
}
const handleOk = () => {
openModal()
loading.value = true
postRelease().then( res => {
console.log(res, '----');
debugger
message.success('上线成功')
loading.value = false
handleCancel()
}).catch(err => {
message.error({
title: '错误提示',
content: err?.response?.data?.msg || '上线失败'
})
loading.value = false
handleCancel()
})
}
const handleCancel = () => {
controlVisible.value = false
}
return {
loading,
handleOk,
openModal,
handleCancel,
controlVisible
}
}
})
</script>3. provide and inject
In the parent component, expose the property or method through provide, and the child component accepts it through inject, and as long as it is a descendant of the parent component, it can receive the value exposed by the parent component through inject
parent component:
<template>
<div>
<a-button style="margin: 20px" type="primary" @click="showModal">上线</a-button>
<OnlineModal />
</div>
</template>
<script lang="ts">
import { defineComponent, provide, ref } from 'vue'
import { useRoute } from 'vue-router'
import OnlineModal from './onlineModal.vue'
export default defineComponent({
components: {
OnlineModal
},
setup() {
const route = useRoute()
const controlIfVisible = ref<boolean>(false)
provide('controlIfVisible', controlIfVisible)
const showModal = (sonValue) => {
controlIfVisible.value = sonValue
}
provide('handle', showModal)
return {
route,
showModal,
controlIfVisible
}
}
})
</script>
Subassembly:
<template>
<a-modal :visible="controlVisible" title="发布上线" @ok="handleOk" @cancel="handleCancel">
<template #footer>
<a-button key="back" @click="handleCancel">取消</a-button>
<a-button key="submit" type="primary" :loading="loading" @click="handleOk">确认发布</a-button>
