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}]
