正则替换字符串内容-replace

'You are signing code ${code}' 替换 ${code}

可以使用正则表达式来替换 ${code}。以下是一个示例代码：

const message = 'You are signing into abcd.exchange for security code ${code}';
const code = '123456';

const regex = /\${code}/g;
const replacedMessage = message.replace(regex, code);

console.log(replacedMessage); // 输出: 'You are signing into abcd.exchange for security code 123456'

在这个示例中，我们首先定义了原始消息和要替换的代码。然后，我们使用正则表达式来匹配所有的 ${code} 字符串，并使用 replace 函数将它们替换为正确的代码值。最后，我们打印出替换后的消息。

str.replace && .replaceAll

'You are signing code ${code}'.replace('${code}',8888)
'You are signing code 8888'
'You are signing code ${code}-${code}'.replaceAll('${code}',8888)
'You are signing code 8888-8888'
'You are signing code ${code}-${code}'.replace('${code}',8888)
'You are signing code 8888-${code}'
