这样打开了一个json文件
更改整个文件的内容如下
{
// 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"
// }
// \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 Tab键（横向跳到下一制表符位置）
// \" 的意思是 双引号
// \n 的意思是回车换行
"vue_learn_template": {
"prefix": "!v", //触发标志
"body": [
