第一步
打开VS code,菜单栏选择 文件-首选项-用户代码片段，选择vue.json
第二步
在代码片段内输入如下内容：
{// Place your snippets for vue here. Each snippet is defined under a snippet name and has a prefix, body and // description. The prefix is what is used to trigger the snippet and the body will be expanded and inserted. Possible variables are:// $1, $2 for tab stops, $0 for the final cursor position, and ${1:label}, ${2:another} for placeholders. Placeholders with the // same ids are connected.// Example:// "Print to console": {// "prefix": "log",// "body": [// "console.log('$1');",// "$2"// ],// "description": "Log output to console"// }"Print to console": {"prefix": "vue","body": ["<!--"," 功能：${1:功能描述}"," 时间：$CURRENT_YEAR年$CURRENT_MONTH月$CURRENT_DATE日 $CURRENT_HOUR:$CURRENT_MINUTE:$CURRENT_SECOND"," 版本：v1.0","-->","<template>","</template>","","<script>","//这里可以导入其他文件（比如：组件，工具js，第三方插件js，json文件，图片文件等等）","//例如：import 《组件名称》 from '《组件路径》';","export default {"," // 组件名称"," name: 'demo',"," // 组件参数 接收来自父组件的数据"," props: {},"," // 局部注册的组件,import引入的组件需要注入到对象中才能使用"," components: {},"," // 组件状态值"," data () {"," return {}"," },"," // 计算属性"," computed: {},"," // 侦听器"," watch: {},"," // 组件方法"," methods: {},"," // 以下是生命周期钩子 注：没用到的钩子请自行删除"," /**"," * 在实例初始化之后，组件属性计算之前，如data属性等"," */"," beforeCreate () {"," },"," /**"," * 组件实例创建完成，属性已绑定，但DOM还未生成，$ el属性还不存在"," */"," created () {"," },"," /**"," * 在挂载开始之前被调用：相关的 render 函数首次被调用。"," */"," beforeMount () {"," },"," /**"," * el 被新创建的 vm.$ el 替换，并挂载到实例上去之后调用该钩子。"," * 如果 root 实例挂载了一个文档内元素，当 mounted 被调用时 vm.$ el 也在文档内。"," */"," mounted () {"," },"," /**"," * 数据更新时调用，发生在虚拟 DOM 重新渲染和打补丁之前。"," * 你可以在这个钩子中进一步地更改状态，这不会触发附加的重渲染过程。"," */"," beforeUpdate () {"," },"," /**"," * 由于数据更改导致的虚拟 DOM 重新渲染和打补丁，在这之后会调用该钩子。"," * 当这个钩子被调用时，组件 DOM 已经更新，所以你现在可以执行依赖于 DOM 的操作。"," */"," updated () {"," },"," /**"," * keep-alive 组件激活时调用。 仅针对keep-alive 组件有效"," */"," activated () {"," },"," /**"," * keep-alive 组件停用时调用。 仅针对keep-alive 组件有效"," */"," deactivated () {"," },"," /**"," * 实例销毁之前调用。在这一步，实例仍然完全可用。"," */"," beforeDestroy () {"," },"," /**"," * Vue 实例销毁后调用。调用后，Vue 实例指示的所有东西都会解绑定，"," * 所有的事件监听器会被移除，所有的子实例也会被销毁。"," */"," destroyed () {"," }","}","</script> ","","<!-- Add \"scoped\" attribute to limit CSS to this component only -->","<!--使用了scoped属性之后，父组件的style样式将不会渗透到子组件中，-->","<!--然而子组件的根节点元素会同时被设置了scoped的父css样式和设置了scoped的子css样式影响，-->","<!--这么设计的目的是父组件可以对子组件根元素进行布局。-->","<style scoped>","","</style>","$2"],"description": "Log output to console"}
}
第三步
在VS code里新建一个vue文件，在文件空白处输入vue ，按 Tab 键，即可按照模板生成信息。
