Vue-Echarts-Resize

几种echarts图表自适应方法比较,万能解决方案第3种,在div上绑定对应onresize方法

Build Setup

# install dependencies
npm install

# serve with hot reload at localhost:8080
npm run dev

# build for production with minification
npm run build

几种方法比较【万能方法为第3种】

1.使用window.onresize

let myChart = echarts.init(document.getElementById(dom))
window.onresize = function () {
  	myChat.resize()
}

优点:可以根据窗口大小实现自适应

缺点

1.多个图表自适应写法比较麻烦(当一个页面的图表太多时,这样写法不是很灵活);
let myChart1 = echarts.init(document.getElementById(dom1))
let myChart2 = echarts.init(document.getElementById(dom2))
window.onresize = function () {
  	myChat1.resize()
  	myChat2.resize()
}
2.多个vue页面有onresize方法时,会被覆盖;

3.当vue页面路由跳转到下一个页面时,上一个页面的onresize方法会继续执行,
(这个时候下一个页面已经不需要onresize方法执行了,当图表过多时会造成页面卡顿)

2.使用window.addEventListener添加resize方法

let myChart = echarts.init(document.getElementById(dom))
let sizeFun = function () {
  	myChat.resize()
}
window.addEventListener('resize', sizeFun )

优点:

1.可以根据窗口大小实现自适应;

2.将图表方法封装以后,只需要执行一遍就可以实现多个图表的自适应;

3.不会被覆盖

缺点:

当vue页面路由跳转到下一个页面时,上一个页面的onresize方法会继续执行
【造成这个问题的原因是因为vue是单页面应用,echarts中的操作都是基于window,
当然也可以使用window.removeEventListener在下一个页面删除绑定的方法】

点击查看window.removeEventListener使用注意点


3.实现在div使用onresize方法

实现原理:在div上实现类似window的onresize 监听,这样既能实现图表的自适应,也不会因为页面跳转之后继续执行三个页面的onresize 方法

实现方法:

  1. 引入esresize.js(项目存放有)

2. 在div上绑定对应onresize 方法

优点:

1.可以根据窗口大小实现自适应
2.页面跳转不会执行上次操作
3.多个方法不会覆盖

缺点:
