在对象文字方法之间传递异步值

const obj = {
  asyncMethod: function(callback) {
    // 异步操作
    setTimeout(function() {
      const result = '异步值';
      callback(result);
    }, 1000);
  },
  processAsyncValue: function(value) {
    // 处理异步值
    console.log(value);
  }
};

obj.asyncMethod(obj.processAsyncValue);

const obj = {
  asyncMethod: function() {
    return new Promise(function(resolve, reject) {
      // 异步操作
      setTimeout(function() {
        const result = '异步值';
        resolve(result);
      }, 1000);
    });
  },
  processAsyncValue: function(value) {
    // 处理异步值
    console.log(value);
  }
};

obj.asyncMethod().then(obj.processAsyncValue);

const obj = {
  asyncMethod: async function() {
    // 异步操作
    return new Promise(function(resolve, reject) {
      setTimeout(function() {
        const result = '异步值';
        resolve(result);
      }, 1000);
    });
  },
  processAsyncValue: function(value) {
    // 处理异步值
    console.log(value);
  }
};

(async function() {
  const value = await obj.asyncMethod();
  obj.processAsyncValue(value);
})();
