html通过CDN引入Vue组件抽出复用

html通过CDN引入Vue组件抽出复用

近期遇到个需求，就是需要在.net MVC的项目中，对已有的项目的首页进行优化，也就是写原生html和js。但是咱是一个写前端的，写html还可以，.net的话，开发也不方便，还得安装Visual Studio启动项目。所以就计划在html文件中开发，然后移植到.net的项目中。
功能说明：需要开发一个dashboard，也就是大屏可视化，多个模块，然后由图表作为主要内容。那么就需要组件封装了，html如何封装组件呢？父组件又如何使用子组件呢？

效果图

代码实现

子组件js

bash 复制代码

var link = document.createElement('link');
link.rel = 'stylesheet';
link.href = './son.css';
document.head.appendChild(link);

let htmlstr = `
  <div>
    <div class="son-box">{{ title }} - {{ content }} - {{str}}</div>
    <div class="echart2">2</div>
  </div>
`

// my-component.js
Vue.component('my-component', {
  props: ['title', 'content'],
  template: htmlstr,
  data(){
    return{
      str:1
    }
  },
  mounted(){
    
      this.initEchart()
  },
  methods:{
    initEchart(){
      


      var option = {
          xAxis: {
              type: 'category',
              data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat', 'Sun']
          },
          yAxis: {
              type: 'value'
          },
          series: [
              {
                  data: [150, 230, 224, 218, 135, 147, 260],
                  type: 'line'
              }
          ]
      };


      setTimeout(()=>{
          let chartDom2 = document.getElementsByClassName('echart2')[0]
	      var myChart2 = echarts.init(chartDom2);
	      myChart2.setOption(option);
      })
      
    }
  }
});
