js 对象数组根据对象中的属性排序

           function createComparisonFunction(propertyName){
                return function(object1,object2){
                    var value1 = object1[propertyName];
                    var value2 = object2[propertyName];

                    if(value1 < value2){
                        return -1;
                    }else if(value1 > value2){
                        return 1;
                    }else{
                        return 0;
                    }
                };
            };

            var data = [{name:'Zacharty',age: 31},{name:'Nicholas',age: 29},{name:'Nicholas',age: 30}];
            // 这里根据数组对象中的age属性排序
            console.log(data.sort(createComparisonFunction('age')));
            // [{name:'Nicholas',age: 29},{name:'Nicholas',age: 30},{name:'Zacharty',age: 31}]
