【前端】vscode javascript 代码片段失效问题解决

文件--首选项--用户代码片段-vue.json : 添加

// {
//     // Place your global snippets here. Each snippet is defined under a snippet name and has a scope, prefix, body and 
//     // description. Add comma separated ids of the languages where the snippet is applicable in the scope field. If scope 
//     // is left empty or omitted, the snippet gets applied to all languages. 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": {
//     //     "scope": "javascript,typescript",
//     //     "prefix": "log",
//     //     "body": [
//     //         "console.log('$1');",
//     //         "$2"
//     //     ],
//     //     "description": "Log output to console"
//     // }
// }
