詳解vscode中console.log的兩種快速寫法

Posted on by

（一）方法一：直接在script標簽中提前定義，僅適用於該html文件！

 let add = function(a,b){
 	return a + b;
 };
 console.log(add(20,300));
 
 const { ['log']:C } = console;
 C(add(20,300));

（二）方法二：按tab鍵快速生成console.log，且光標在()內部,再次按tab鍵光標自動跳轉到下一行！
1、打開vscode編輯器，選擇文件->首選項->用戶片段，輸入javascript.json並按下enter進入。
初次使用我們會發現一段被註釋的代碼如下：

{
	// Place your snippets for javascript 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"
	// }
}

2、解除Example以下的區間代碼如下，其中部分參數意義如下：
①prefix:代碼快捷鍵的入口,在這裡我們根據個人習慣進行設置即可，如我設置的cl,那麼配合tab健就可以直接生成console.log；
②body表示代碼主體：
$1表示生成代碼快速生成後後光標首次出現的位置
$2寫在”console.log(‘$1’);”下面,表示在快速生成console.log()後,代碼後會空出一行,並且再次按tab鍵時,光標會跳轉到$2（空出的一行）的位置

{
	// Place your snippets for javascript 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": "cl",
		"body": [
			"console.log('$1');",
			"$2"
		],
		"description": "Log output to console"
	}
}
