1、简单数组简单排序
<script type="text/javascript"> var arrSimple=new Array(1,8,7,6); arrSimple.sort(); document.writeln(arrSimple.join()); </script>
2、简单数组自定义排序
<script type="text/javascript"> var arrSimple2=new Array(1,8,7,6); arrSimple2.sort(function(a,b){ return b-a}); document.writeln(arrSimple2.join()); </script>
解释:a,b表示数组中的任意两个元素,若return > 0 b前a后;reutrn < 0 a前b后;a=b时存在浏览器兼容
简化一下:a-b输出从小到大排序,b-a输出从大到小排序。
3、简单对象List自定义属性排序
<script type="text/javascript"> var objectList = new Array(); function Persion(name,age){ this.name=name; this.age=age; } objectList.push(new Persion('jack',20)); objectList.push(new Persion('tony',25)); objectList.push(new Persion('stone',26)); objectList.push(new Persion('mandy',23)); //按年龄从小到大排序 objectList.sort(function(a,b){ return a.age-b.age}); for(var i=0;i<objectList.length;i++){ document.writeln('<br />age:'+objectList[i].age+' name:'+objectList[i].name); } </script>
4、简单对象List对可编辑属性的排序
<script type="text/javascript"> var objectList2 = new Array(); function WorkMate(name,age){ this.name=name; var _age=age; this.age=function(){ if(!arguments) { _age=arguments[0];} else { return _age;} } } objectList2.push(new WorkMate('jack',20)); objectList2.push(new WorkMate('tony',25)); objectList2.push(new WorkMate('stone',26)); objectList2.push(new WorkMate('mandy',23)); //按年龄从小到大排序 objectList2.sort(function(a,b){ return a.age()-b.age(); }); for(var i=0;i<objectList2.length;i++){ document.writeln('<br />age:'+objectList2[i].age()+' name:'+objectList2[i].name); } </script>
