纯JS方法:我的答案是基于生成一个返回相同值的字符串，无论属性顺序是否相同。设置对象可用于切换大小写和空白是否重要。(为了避免失去焦点，我没有包括那些支持函数，或者我猜应该在任何实用程序集中的isObject。)

这里也没有显示，但为了减少字符串比较时间，如果对象很大，你想加快比较，你也可以散列字符串和比较子字符串;这只适用于非常大的对象(当然也有很小的机会出现错误的相等)。

然后你可以比较genObjStr(obj1) ?= genObjStr(obj2)

function genObjStr(obj, settings) {
// Generate a string that corresponds to an object guarenteed to be the same str even if
// the object have different ordering. The string would largely be used for comparison purposes

var settings = settings||{};
var doStripWhiteSpace = defTrue(settings.doStripWhiteSpace);
var doSetLowerCase = settings.doSetLowerCase||false;

if(isArray(obj)) {
    var vals = [];
    for(var i = 0; i < obj.length; ++i) {
        vals.push(genObjStr(obj[i], settings));
    }
    vals = arraySort(vals);
    return vals.join(`,`);

} else if(isObject(obj)) {

    var keys = Object.keys(obj);
    keys = arraySort(keys);

    var vals = [];
    for(var key of keys) {
        
        var value = obj[key];
        
        value = genObjStr(value, settings);

        if(doStripWhiteSpace) {
            key = removeWhitespace(key);
            var value = removeWhitespace(value);
        };
        if(doSetLowerCase) {
            key = key.toLowerCase();
            value = value.toLowerCase();
        }

        vals.push(value);
    }
    var str = JSON.stringify({keys: keys, vals: vals});
    return str
} else {
    if(doStripWhiteSpace) {
        obj = removeWhitespace(obj);
    };
    if(doSetLowerCase) {
        obj = obj.toLowerCase();
    }
    return obj
}

}

var obj1 = {foo: 123, bar: `Test`};
var obj2 = {bar: `Test`, foo: 123};

console.log(genObjStr(obj1) == genObjStr(obj1))

我不知道是否有人发布过类似的东西，但这是我做的一个检查对象相等的函数。

function objectsAreEqual(a, b) {
  for (var prop in a) {
    if (a.hasOwnProperty(prop)) {
      if (b.hasOwnProperty(prop)) {
        if (typeof a[prop] === 'object') {
          if (!objectsAreEqual(a[prop], b[prop])) return false;
        } else {
          if (a[prop] !== b[prop]) return false;
        }
      } else {
        return false;
      }
    }
  }
  return true;
}

而且，它是递归的，所以它也可以检查深度相等，如果你这么称呼它的话。

经过这么多的搜索，我找到了以下工作解决方案

function isEquivalent(a, b) {
   // Create arrays of property names
   var aProps = Object.getOwnPropertyNames(a);
   var bProps = Object.getOwnPropertyNames(b);

  // If number of properties is different, objects are not equivalent
  if (aProps.length != bProps.length) {
     return false;
  }

  for (var i = 0; i < aProps.length; i++) {
     var propName = aProps[i];

    // If values of same property are not equal, objects are not equivalent
     if (a[propName] !== b[propName]) {
         return false;
     }
  }

// If we made it this far, objects are considered equivalent
return true; }

更多信息:JavaScript中的对象平等

这是一个非常干净的CoffeeScript版本，你可以这样做:

Object::equals = (other) ->
  typeOf = Object::toString

  return false if typeOf.call(this) isnt typeOf.call(other)
  return `this == other` unless typeOf.call(other) is '[object Object]' or
                                typeOf.call(other) is '[object Array]'

  (return false unless this[key].equals other[key]) for key, value of this
  (return false if typeof this[key] is 'undefined') for key of other

  true

下面是测试:

  describe "equals", ->

    it "should consider two numbers to be equal", ->
      assert 5.equals(5)

    it "should consider two empty objects to be equal", ->
      assert {}.equals({})

    it "should consider two objects with one key to be equal", ->
      assert {a: "banana"}.equals {a: "banana"}

    it "should consider two objects with keys in different orders to be equal", ->
      assert {a: "banana", kendall: "garrus"}.equals {kendall: "garrus", a: "banana"}

    it "should consider two objects with nested objects to be equal", ->
      assert {a: {fruit: "banana"}}.equals {a: {fruit: "banana"}}

    it "should consider two objects with nested objects that are jumbled to be equal", ->
      assert {a: {a: "banana", kendall: "garrus"}}.equals {a: {kendall: "garrus", a: "banana"}}

    it "should consider two objects with arrays as values to be equal", ->
      assert {a: ["apple", "banana"]}.equals {a: ["apple", "banana"]}



    it "should not consider an object to be equal to null", ->
      assert !({a: "banana"}.equals null)

    it "should not consider two objects with different keys to be equal", ->
      assert !({a: "banana"}.equals {})

    it "should not consider two objects with different values to be equal", ->
      assert !({a: "banana"}.equals {a: "grapefruit"})

我知道这有点老了，但我想添加一个解决方案，我想出了这个问题。 我有一个对象，我想知道它的数据什么时候改变。类似于Object。我所做的是:

function checkObjects(obj,obj2){
   var values = [];
   var keys = [];
   keys = Object.keys(obj);
   keys.forEach(function(key){
      values.push(key);
   });
   var values2 = [];
   var keys2 = [];
   keys2 = Object.keys(obj2);
   keys2.forEach(function(key){
      values2.push(key);
   });
   return (values == values2 && keys == keys2)
}

这里可以复制并创建另一组数组来比较值和键。 这很简单，因为它们现在是数组，如果对象大小不同将返回false。

我的版本，包括发现差异的地方，以及差异是什么。

function DeepObjectCompare(O1, O2)
{
    try {
        DOC_Val(O1, O2, ['O1->O2', O1, O2]);
        return DOC_Val(O2, O1, ['O2->O1', O1, O2]);
    } catch(e) {
        console.log(e.Chain);
        throw(e);
    }
}
function DOC_Error(Reason, Chain, Val1, Val2)
{
    this.Reason=Reason;
    this.Chain=Chain;
    this.Val1=Val1;
    this.Val2=Val2;
}

function DOC_Val(Val1, Val2, Chain)
{
    function DoThrow(Reason, NewChain) { throw(new DOC_Error(Reason, NewChain!==undefined ? NewChain : Chain, Val1, Val2)); }

    if(typeof(Val1)!==typeof(Val2))
        return DoThrow('Type Mismatch');
    if(Val1===null || Val1===undefined)
        return Val1!==Val2 ? DoThrow('Null/undefined mismatch') : true;
    if(Val1.constructor!==Val2.constructor)
        return DoThrow('Constructor mismatch');
    switch(typeof(Val1))
    {
        case 'object':
            for(var m in Val1)
            {
                if(!Val1.hasOwnProperty(m))
                    continue;
                var CurChain=Chain.concat([m]);
                if(!Val2.hasOwnProperty(m))
                    return DoThrow('Val2 missing property', CurChain);
                DOC_Val(Val1[m], Val2[m], CurChain);
            }
            return true;
        case 'number':
            if(Number.isNaN(Val1))
                return !Number.isNaN(Val2) ? DoThrow('NaN mismatch') : true;
        case 'string':
        case 'boolean':
            return Val1!==Val2 ? DoThrow('Value mismatch') : true;
        case 'function':
            if(Val1.prototype!==Val2.prototype)
                return DoThrow('Prototype mismatch');
            if(Val1!==Val2)
                return DoThrow('Function mismatch');
            return true;
        default:
            return DoThrow('Val1 is unknown type');
    }
}
