【Javascript】js中将文本转为十六进制文本
Posted on 2024-02-01 23:06:13 by 主打一个C++
封装类：HexConverter
class HexConverter {
// 将文本转换为十六进制字符串
textToHex(text) {
let hex = '';
for (let i = 0; i < text.length; i++) {
const hexChar = text.charCodeAt(i).toString(16);
hex += hexChar.length === 1 ? '0' + hexChar : hexChar;
}
return hex;
}
// 将十六进制字符串转换为文本
hexToText(hex) {
let text = '';
for (let i = 0; i < hex.length; i += 2) {
const hexByte = hex.substr(i, 2);
text += String.fromCharCode(parseInt(hexByte, 16));
}
return text;
}
}保证对其：
class HexConverter {
// 将文本转换为十六进制字符串
textToHex(text) {
let hex = '';
for (let i = 0; i < text.length; i++) {
hex += text.charCodeAt(i).toString(16).padStart(2, '0');
}
return hex;
}
// 将十六进制字符串转换为文本
hexToText(hex) {
let text = '';
for (let i = 0; i < hex.length; i += 2) {
text += String.fromCharCode(parseInt(hex.substr(i, 2), 16));
}
return text;
}
}调用实例：
const converter = new HexConverter1();
const originalText = "hello world";
const hexString = converter.textToHex(originalText);
console.log(`文本转换为十六进制：${hexString}`);
const restoredText = converter.hexToText(hexString);
console.log("还原后的文本:", restoredText);html测试实例：
