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; }

我发现比较两个javascript对象的值而忽略属性顺序的一个简单方法是使用JSON stringify replacer函数:

const compareReplacer = (key, value) => {
    if(typeof value === 'object' && !(value instanceof Array))
        return Object.entries(value).sort();
    return value;
}
export const compareObjects = (a, b) => JSON.stringify(a, compareReplacer) === JSON.stringify(b, compareReplacer);

这将在每一步对属性进行排序，以便字符串结果对属性顺序不变。以前可能有人这样做过，但我只是想分享一下，以防万一:)。

只是想利用一些es6的特性来贡献我的对象比较版本。它不考虑订单。在将所有if/else转换为三元后，我带来了以下内容:

function areEqual(obj1, obj2) {

    return Object.keys(obj1).every(key => {

            return obj2.hasOwnProperty(key) ?
                typeof obj1[key] === 'object' ?
                    areEqual(obj1[key], obj2[key]) :
                obj1[key] === obj2[key] :
                false;

        }
    )
}

最简单和逻辑的解决方案，比较一切像对象，数组，字符串，Int…

JSON。stringify({a: val1}) == JSON。stringify ({a: val2})

注意:

你需要用你的Object替换val1和val2 对于对象，必须对两侧对象进行递归排序(按键)

EDIT: This method is quite flawed, and is rife with its own issues. I don't recommend it, and would appreciate some down-votes! It is problematic because 1) Some things can not be compared (i.e. functions) because they can not be serialized, 2) It isn't a very fast method of comparing, 3) It has ordering issues, 4) It can have collision issues/false positives if not properly implemented, 5) It can't check for "exactness" (===), and instead is based of value equality, which is oftentimes not what is desired in a comparison method.

这个问题的一个简单解决方案是对JSON字符串进行排序(每个字符)，但很多人没有意识到这一点。这通常也比这里提到的其他解决方案更快:

function areEqual(obj1, obj2) {
    var a = JSON.stringify(obj1), b = JSON.stringify(obj2);
    if (!a) a = '';
    if (!b) b = '';
    return (a.split('').sort().join('') == b.split('').sort().join(''));
}

关于这个方法的另一个有用的事情是，您可以通过向JSON传递一个“replace”函数来筛选比较。stringify函数(https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify#Example_of_using_replacer_parameter)。下面只比较所有命名为“derp”的对象键:

function areEqual(obj1, obj2, filter) {
    var a = JSON.stringify(obj1, filter), b = JSON.stringify(obj2, filter);
    if (!a) a = '';
    if (!b) b = '';
    return (a.split('').sort().join('') == b.split('').sort().join(''));
}
var equal = areEqual(obj1, obj2, function(key, value) {
    return (key === 'derp') ? value : undefined;
});

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"})
