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
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);
})
}
}
});
