深入对比两个对象（key相同）value是否相等，如果相等返回true，如果不等，返回不相等的字段的key用.分隔，

function compareObject(obj1, obj2) {

}
const a = {a:1, b: 2, c:{d:1}}
const b = {a: 1, b: 2, c:{d:2}}
compareObject(a, b);
// => ['c.d']

const c = {a:1, b: 2, c:{d:1, f: 2}};
const d = {a:1, b: 3, c:{d:5, f: 1}};
compareObject(c, d);
// => ['b', 'c.d', 'c.f']

      }
    }
    if(list.length===0){
    	return true
    }return list
}

不知道是以 obj1 的 key 为基准还是所有 key

function merge(keys1, keys2){
  var keys = [].concat(keys1);
  keys2.forEach(function (i){
    if (keys.indexOf(i) === -1){
      keys.push(i);
    }
  });
  return keys;
}

function compareObject(obj1, obj2){
  var keys1 = Object.keys(obj1);
  var keys2 = Object.keys(obj2);
  var keys = merge(keys1, keys2);
  var result = [];
  keys.forEach(function (key){
    if (typeof obj1[key] === 'object' && typeof obj2[key] === 'object'){
      var children = compareObject(obj1[key], obj2[key]);
      if (children !== true) {
        children = children.map(function (i){
          return key + '.' + i;
        });
        result = result.concat(children);
      }
    }else if (obj1[key] !== obj2[key]) {
      result.push(key);
    }
  });
  return !result.length ? true : result;
}

JSON.stringify 有键值顺序风险并忽略一些值。

这个代码放在浏览器里面运行报错,代码如下: `var bbbb = {a:1, b: 2, c:{d:1}} var cccc = {a: 1, b: 2, c:{d:2}} compareObject(bbbb,cccc); function compareObject(obj1, obj2) { var list = [] for(var key in obj1) { if(typeof obj1[key] === 'object') { var newlist = compareObject(obj1[key], obj2[key]) if(Object.prototype.toString.call(newlist) === "[object Array]") { //把遍历对象里得到的不同的值放到数组里面去. newlist = newlist.map(function (value) { return key + '.' +value }) list = list.concat(newlist) }

   } else if(obj1[key] != obj2[key]) {
       list.push(key)
   }
   return list.length == 0? true: list

} }` 报错信息: VM74:1 Uncaught SyntaxError: Identifier 'bbbb' has already been declared at :1:1 找不到什么原因,求指导.
