vue 全家桶需要nodejs支持
在用cdn引入vue的情况下[1],给HTML文件使用.VUE组件的方式。
结合
[1] 如下,在html中引入使用vue
1 | <script src="//i2.wp.com/cdn.bootcdn.net/ajax/libs/vue/2.6.11/vue.js"></script> |
[2] 引入
1 | <script src="./src/js/httpVueLoader.js"></script> |
[3] 使用方式
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | <!-- index.html --> <script> Vue.use(httpVueLoader); new Vue({ el:'#app', data:{}, // 相对路径引用参考 components: { 'my-swiper': httpVueLoader('./src/components/swiper.vue'), 'my-imgitme': httpVueLoader('./src/components/ImgItem.vue'), 'my-cc': httpVueLoader('./src/components/cc.vue') } }) </script> |
1 2 3 4 5 6 7 8 9 | // cc.vue <script> module.exports = { // data 返回function // 部分报错按照报错信息修改即可 data: function() { return {}; } </script> |
[4] 下载方式
