如果value包含逗号，则循环并将对象字符串值转换为object

const str = "name:John,age:30,city:New York";

function stringToObject(str) {
  const obj = {};
  const keyValuePairs = str.split(',');
  
  keyValuePairs.forEach(pair => {
    const [key, value] = pair.split(':');
    obj[key] = value;
  });
  
  return obj;
}

const obj = stringToObject(str);
console.log(obj); // 输出: { name: 'John', age: '30', city: 'New York' }

function stringToObject(str) {
  const obj = {};
  const keyValuePairs = str.split(',');
  
  keyValuePairs.forEach(pair => {
    const parts = pair.split(':');
    if (parts.length === 2) {
      const [key, value] = parts;
      obj[key] = value;
    } else {
      console.error(`Invalid key-value pair: ${pair}`);
    }
  });
  
  return obj;
}

function stringToObject(str) {
  const obj = {};
  const keyValuePairs = str.split(',');
  
  keyValuePairs.forEach(pair => {
    const [key, value] = pair.split(':').map(s => s.replace(/^"|"$/g, ''));
    obj[key] = value;
  });
  
  return obj;
}
