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"})

let std1 = {
  name: "Abhijeet",
  roll: 1
}

let std2 = {
  name: "Siddharth",
  roll: 2
}

console.log(JSON.stringify(std1) === JSON.stringify(std2))

ES6:我能做到的最小代码是这样的。它通过对代表对象的所有键值数组进行字符串化来进行递归的深度比较，唯一的限制是没有方法或符号进行比较。

const compareObjects = (a, b) => { let s = (o) => Object.entries(o).sort()。映射(i => { if(i[1]实例对象)i[1] = s(i[1]); 返回我 }) 返回JSON.stringify(s(a)) === JSON.stringify(s(b)) ｝ console.log (compareObjects ({b: 4,答:{b: 1}}, {} {b: 1, b: 4}));

重要提示:这个函数正在执行JSON。stringfy在数组中，并将键排序，而不是在对象本身中:

["a" ["b"， 1]] [" b ", 4]

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))

是的，另一个答案……

Object.prototype.equals = function (object) { if (this.constructor !== object.constructor) return false; if (Object.keys(this).length !== Object.keys(object).length) return false; var obk; for (obk in object) { if (this[obk] !== object[obk]) return false; } return true; } var aaa = JSON.parse('{"name":"mike","tel":"1324356584"}'); var bbb = JSON.parse('{"tel":"1324356584","name":"mike"}'); var ccc = JSON.parse('{"name":"mike","tel":"584"}'); var ddd = JSON.parse('{"name":"mike","tel":"1324356584", "work":"nope"}'); $("#ab").text(aaa.equals(bbb)); $("#ba").text(bbb.equals(aaa)); $("#bc").text(bbb.equals(ccc)); $("#ad").text(aaa.equals(ddd)); <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> aaa equals bbb? <span id="ab"></span> <br/> bbb equals aaa? <span id="ba"></span> <br/> bbb equals ccc? <span id="bc"></span> <br/> aaa equals ddd? <span id="ad"></span>
