封装分享组件

h-share.gif

1. 引入相关的JS

2. 利用虚拟DOM封装组件

var VueQrcode = window.VueQrcode;
Vue.component('qrcode', VueQrcode);
Vue.component('h-share', {
    render: function (createElement) {
        var self = this;
        return createElement(
            'div',
            {
                style: {
                    display: 'inline-block'
                },
            },
            [
                createElement('i', {
                    attrs: {
                        class: 'el-icon-share'
                    },
                    style: {
                        marginRight: '10px'
                    }
                }, '分享'),
                createElement('span', {
                    attrs: {
