uni-app：引入echarts（使用renderjs）

效果

代码

<template><view @click="echarts.onClick" :prop="option" :change:prop="echarts.updateEcharts" id="echarts" class="echarts"></view>
</template><script>export default {data() {return {option: '',x: ["衬衫", "羊毛衫", "雪纺衫", "裤子", "高跟鞋", "袜子"],y: [5, 20, 36, 10, 10, 20]}},onLoad() {this.option = {tooltip: {},xAxis: {data: this.x},yAxis: {},series: [{name: '销量',type: 'bar',data: this.y}]}},methods: {}}
</script><script module="echarts" lang="renderjs">let myChartexport default {mounted() {if (typeof window.echarts === 'function') {this.initEcharts()} else {// 动态引入较大类库避免影响页面展示const script = document.createElement('script')// view 层的页面运行在 www 根目录，其相对路径相对于 www 计算script.src = 'static/js/echarts.js'script.onload = this.initEcharts.bind(this)document.head.appendChild(script)}},methods: {initEcharts() {myChart = echarts.init(document.getElementById('echarts'))// 观测更新的数据在 view 层可以直接访问到myChart.setOption(this.option)},updateEcharts(newValue, oldValue, ownerInstance, instance) {// 监听 service 层数据变更if (myChart != undefined) {myChart.setOption(newValue)}},}}
</script><style>.echarts {width: 100%;height: 300px;}
</style>
