【前端】vscode javascript 代码片段失效问题解决

1. 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"
// 	// }
// }
