AS3 对复杂对象的排序规则[DEMO]

源代码：

package{import flash.display.Sprite;/** *  测试复杂对象的排序 * @author Jave.Lin(afeng) **/public class TestComplexSort extends Sprite{public function TestComplexSort(){super();var lastNameArr:Vector.<String>=new Vector.<String>();lastNameArr.push("Lin","Smith","Steven","Abros","BB","CCC","D","EE","FF","GG","Gates","HH");var firstNameArr:Vector.<String>=new Vector.<String>();firstNameArr.push("Jave","John","Harry","Waston","Bill","Tom","Jerry");var ageMax:uint=150;var personArr:Vector.<Person>=new Vector.<Person>();for (var i:int = 0; i < 10; i++) {var p:Person=new Person();p.firstName=firstNameArr[Math.floor(Math.random()*firstNameArr.length)];p.lastName=lastNameArr[Math.floor(Math.random()*lastNameArr.length)];p.age=Math.floor(Math.random()*ageMax);personArr[i]=p;}trace(personArr);personArr.sort(comparePerson);trace(personArr);}private function comparePersonAge(a:Person,b:Person):int{if(a.age>b.age)return 1;else if(a.age<b.age)return -1;return 0;}private function comparePersonFirstName(a:Person,b:Person):int{if(a.firstName>b.firstName)return 1;else if(a.firstName<b.firstName)return -1;return 0;}private function comparePersonLastName(a:Person,b:Person):int{if(a.lastName>b.lastName)return 1;else if(a.lastName<b.lastName)return -1;return 0;}private function comparePerson(a:Person,b:Person):int{var result:int=0;//这里的排序权重：即：顺序的先后，现在这里是以：FirstName为最优条件//当然你也可以试着换一下排序函数的顺序，即可看到效果。result=comparePersonFirstName(a,b);if(result!=0)return result;result=comparePersonLastName(a,b);if(result!=0)return result;result=comparePersonAge(a,b);if(result!=0)return result;return 0;}}}class Person{public var lastName:String;public var firstName:String;public var age:uint;public function toString():String{return firstName+"."+lastName+" age:"+age;}}

输出：

Harry.D age:43,Waston.FF age:35,Waston.EE age:136,Jave.FF age:94,John.BB age:135,Waston.CCC age:41,Bill.GG age:139,John.BB age:93,Waston.FF age:44,Jave.HH age:65Bill.GG age:139,Harry.D age:43,Jave.FF age:94,Jave.HH age:65,John.BB age:93,John.BB age:135,Waston.CCC age:41,Waston.EE age:136,Waston.FF age:35,Waston.FF age:44
