位置：在Vscode中找到 设置 -> 用户代码片段，在输入框内输入html，并点击第一个html.json。

复制以下代码：

{
    // Place your snippets for html 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",  // 对应的是使用这个模板的快捷键
        "body": [
    "<div id=\"app\">",
    "\t{{message}}",
    "</div>\n",

    "<script src=\"../js/vue.js\"></script>",
    "<script>",
    " //创建Vue实例,得到 ViewModel",
    " const app = new Vue({",
    "\tel: '#app',",
    "\tdata: {",
    "\t\tmessage: '${1:hello}',",
    "\t},",
    "\tmethods: {",
    "\t\t",
    "\t}",
    " });",
    "</script>",
        ],
        "description": "a vue template"  // 模板的描述
    }
}

转义字符解释：

\t \" \n都是转义字符，而空格就是单纯的空格，输入时可以输入空格
\t 的意思是 横向跳到下一制表符位置 等于 Tab键
\" 的意思是 双引号
\n 的意思是回车换行

$1代表着光标，它的位置即光标的默认位置，可以有多个光标：$2,$3,$4等
