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>

如果你真的想比较并返回两个对象的差值。 您可以使用这个包:https://www.npmjs.com/package/deep-diff

或者只使用这个包使用的代码

https://github.com/flitbit/diff/blob/master/index.js

只是不要把它转换成字符串进行比较。

我对这个函数做如下假设:

你控制你比较的对象，你只有基本的值(例如。而不是嵌套的对象、函数等)。 您的浏览器支持Object.keys。

这应该被视为一个简单策略的示范。

/**
 * Checks the equality of two objects that contain primitive values. (ie. no nested objects, functions, etc.)
 * @param {Object} object1
 * @param {Object} object2
 * @param {Boolean} [order_matters] Affects the return value of unordered objects. (ex. {a:1, b:2} and {b:2, a:1}).
 * @returns {Boolean}
 */
function isEqual( object1, object2, order_matters ) {
    var keys1 = Object.keys(object1),
        keys2 = Object.keys(object2),
        i, key;

    // Test 1: Same number of elements
    if( keys1.length != keys2.length ) {
        return false;
    }

    // If order doesn't matter isEqual({a:2, b:1}, {b:1, a:2}) should return true.
    // keys1 = Object.keys({a:2, b:1}) = ["a","b"];
    // keys2 = Object.keys({b:1, a:2}) = ["b","a"];
    // This is why we are sorting keys1 and keys2.
    if( !order_matters ) {
        keys1.sort();
        keys2.sort();
    }

    // Test 2: Same keys
    for( i = 0; i < keys1.length; i++ ) {
        if( keys1[i] != keys2[i] ) {
            return false;
        }
    }

    // Test 3: Values
    for( i = 0; i < keys1.length; i++ ) {
        key = keys1[i];
        if( object1[key] != object2[key] ) {
            return false;
        }
    }

    return true;
}

var object1 = {name: "humza" , gender : "male", age: 23}
var object2 = {name: "humza" , gender : "male", age: 23}
var result = Object.keys(object1).every((key) =>  object1[key] === object2[key])

如果object1在object2上具有相同的值，Result将为true。

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;

        }
    )
}

如果你的问题是检查两个对象是否相等，那么这个函数可能会有用

function equals(a, b) {
const aKeys = Object.keys(a)
const bKeys = Object.keys(b)
if(aKeys.length != bKeys.length) {
    return false
}
for(let i = 0;i < aKeys.length;i++) {
    if(aKeys[i] != bKeys[i]) {
        return false
    } 
}
for(let i = 0;i < aKeys.length;i++) {
    if(a[aKeys[i]] != b[bKeys[i]]) {
        return false
    }
}
return true
}

first we check if the length of the list of keys of these objects is the same, if not we return false to check if two objects are equal they must have the same keys(=names) and the same values of the keys, so we get all the keys of objA, and objB and then we check if they are equal once we find that tow keys are not equal then we return false and then when all the keys are equal then we loop through one of the keys of one of the objects and then we check if they are equal once they are not we return false and after the two loops finished this means they are equal and we return true NOTE: this function works with only objects with no functions
