news 2025/2/27 20:16:09

现在手机都有天气app,使用echarts展示十五天天气预报的需要你遇到过这样离大谱的需求吗？如果没有或许你能从中找到些许思路。

效果

请添加图片描述
看效果是不是有点那么个意思,开局一张图,代码全靠ctrl + c。不多说上代码。

vue模板引擎代码

<template><div ref="xAxisChartRef" class="chart"></div>
</template>
<script setup lang="ts">import { onMounted, ref } from 'vue';import { useECharts } from '@/utils';import { options } from './options';let chart: EChartsType;const xAxisChartRef = ref();onMounted(() => {chart = useECharts(xAxisChartRef.value, options);});
</script><style lang="less" scoped>.chart {height: 300px;background: linear-gradient(90deg, #dde4ff, #fff, #fff, #dde4ff);}
</style>

图表配置

import mock from 'mockjs';
import clear from './assets/clear.png';
import cloudy from './assets/cloudy.png';
import rainy from './assets/rainy.png';
import thundershower from './assets/thundershower.png';
import type { EChartsType } from 'echarts';
const weather = [clear, cloudy, rainy, thundershower];
export const optons = {
