用于更新使用Gmail草稿作为模板的邮件合并代码的JSON.stringify.replace

// 创建邮件合并所需的JavaScript对象
var mergeData = {
  name: "John Doe",
  email: "johndoe@example.com",
  subject: "Regarding your recent purchase",
  message: "Dear {{name}},\n\nThank you for your recent purchase. We appreciate your business.\n\nSincerely,\nThe Team"
};

// 将JavaScript对象转换为JSON字符串
var jsonData = JSON.stringify(mergeData);

// 使用.replace方法替换模板中的字段
var mergedMessage = jsonData.replace(/{{name}}/g, mergeData.name)
                            .replace(/{{email}}/g, mergeData.email)
                            .replace(/{{subject}}/g, mergeData.subject)
                            .replace(/{{message}}/g, mergeData.message);

// mergedMessage现在包含了更新后的邮件合并内容
console.log(mergedMessage);
