目前已解锁以下功能:
- [x] 初始化echarts(initChart)
- [x] 获取echarts参数配置(getOption)
- [x] 生成echarts图表(setOption)
- [x] 监听resize事件触发echarts图表更新
- [x] 加载中loading
// charts.js
import echarts from 'echarts'
export default {
computed: {
// 初始化echarts
getChart () {
return this.$echarts.init(this.$refs.echart)
}
},
watch: {
chartData: {
handler (val) {
val && this.initChart()
}
}
},
mounted () {
this.getChart.showLoading()
window.addEventListener('resize', this.chartResize)
// 移除resize事件
this.$once('hook:beforeDestroy', () => {
window.removeEventListener('resize', this.chartResize)
})
},
methods: {
initChart () {
this.getChart.setOption(this.getOption())
this.getChart.hideLoading()
},
chartResize () {
this.getChart.resize()
}
}
}
example:
<template>
<div>
<div ref="echart" style="height: 600px"></div>
</div>
</template>
<script>
import Charts from '@/components/Charts.js'
export default {
// 混入Charts
mixins: [Charts],
data () {
return {
chartData: []
}
},
mounted () {
// 模拟ajax请求
setTimeout(() => {
this.chartData = [0, 1, 2, 3]
}, 2000)
},
methods: {
getOption () {
// 配置options
return {
xAxis: {
type: "category",
data: ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"],
},
// 代码块...
}
}
}
}
</script>
