ASCII转字符

代码是String.fromCharCode(ASCII码)

console.log(String.fromCharCode(48)); //数字0
console.log(String.fromCharCode(49)); //数字1
console.log(String.fromCharCode(50)); //数字2

console.log(String.fromCharCode(65)); //字母A
console.log(String.fromCharCode(66)); //字母B
console.log(String.fromCharCode(67)); //字母C

console.log(String.fromCharCode(21)); //叹号
console.log(String.fromCharCode(23)); //#号

console.log(String.fromCharCode(10)); //换行符 \n
console.log(String.fromCharCode(13)); //回车符 \r
console.log(String.fromCharCode(9)); //制表符(Tab) \t

字符转ASCII

用字符串对象的charCodeAt方法

console.log('A'.charCodeAt()); //65
console.log('B'.charCodeAt()); //66
console.log('C'.charCodeAt()); //67

console.log('\n'.charCodeAt()); //10
console.log('\r'.charCodeAt()); //13
console.log('\t'.charCodeAt()); //9
