一、下载第三方包
使用npm下载第三方包：npm install @antv/g6
二、父组件代码
<template>
<div id="financialMonitoring" v-loading="loading">
<retainedProfitsMap
:securityId="securityId1"
:symbol="symbol1"
id="retainedProfitsMap"
class="mt10"
/>
</div>
</template>
<script setup lang="ts">
import retainedProfitsMap from './retainedProfitsMap.vue'
const props = defineProps({
symbol: {
type: String,
default: ''
},
securityId: {
type: [String, Number],
required: true
}
})
const loading = ref(false) // 加载状态
const securityId1 = ref(props.securityId) // 证券id
const symbol1 = ref(props.symbol) // 证券代码
// 监听参数重新赋值
watch(
() => [props.securityId, props.symbol],
(newValue: any, oldValue: any) => {
if (newValue[0] != oldValue[0]) {
securityId1.value = newValue[0]
}
if (newValue[1] != oldValue[1]) {
symbol1.value = newValue[1]
}
editIndex.value = 1
dateRange.value = []
getFinanciaMonitoringData()
},
{ deep: true }
)
</script>
三、子组件代码
<template>
<ItemCard title="脑图" v-loading="loading">
<template #rightPart>
<el-date-picker
v-model="dateYear"
type="year"
value-format="YYYY"
placeholder="请选择年份"
:editable="false"
:clearable="false"
:disabled-date="disabledDate"
@change="changeDate"
class="year-select"
ref="datePicker"
/>
</template>
<template #otherContent>
<div id="container"></div>
</template>
</ItemCard>
</template>
<script setup lang="ts">

editIndex: {

})
const loading = ref(false) // 加载状态
const dateYear = ref<any>('') // 年份
const symbol1 = ref(props.symbol) // 证券代码
const graphMap = ref() // 脑图dom
const mapData = ref({}) // 脑图数据
const datePicker = ref() // 时间筛选框ref
// 监听参数重新赋值
watch(
() => [props.symbol],
(newValue: any, oldValue: any) => {
if (newValue[0] != oldValue[0]) {
symbol1.value = newValue[0]
}
