项目中有些代码模块是固定的，如下面的代码所示，为了不重复写这些相同的代码，我们可以使用快键键一键生成模板。
流程：
中文：首选项-> 用户代码片段 -> 输入框中输入vue,找到vue.json文件（没有vue.json,选vue也可）-> 定义所需的代码段
英文：Preferences->Configure Snippets-> 输入框中输入vue,找到vue.json文件（没有vue.json,选vue也可）-> 定义所需的代码段
定义代码段：
定义了两段代码模版，vue3,vue32
其中$1,$2,$3是鼠标焦点位置，点击tab可以切换到$2,$3的位置。
{"vue3 template": {"prefix": "vue3", //键入该值，按tab快捷产生"body": ["<script setup lang=\"ts\">","$3","</script>","","<template>"," $1","</template>","","<style scoped lang=\"scss\">","$2","</style>",],"description": "Log output to vue3 template"},"vue3 template2": {"prefix": "vue32", //键入该值，按tab快捷产生"body": ["<script setup lang=\"ts\">","$3","console.log('');","</script>","","<template>"," $1","</template>","","<style scoped lang=\"scss\">","$2","</style>",],"description": "Log output to vue3 template2"},
}
在vue文件中输入vue3,vue32,回车即可
生成vue3模版
生成vue32模版
