sort()

sort()是按照字符编码的顺序进行排序;
<!doctype html>
<htm>
 <head>
  <meta http-equiv="Content-type" content="text/html charset=utf-8">
  <title></title>
  </head>
<body>
    sort()是按照字符编码的顺序进行排序;
 </body>
</html>
<script type="text/javascript"> 
//例1：按字母顺序进行排序
var arr1 = new Array(6)
arr1[0] = "George"
arr1[1] = "Cohn"
arr1[2] = "Thomas"
arr1[3] = "James"
arr1[4] = "Adrew"
arr1[5] = "Bartin"
console.log(arr1.sort());
//["Adrew", "Bartin", "Cohn", "George", "James", "Thomas"]

//例2：按照数值的大小对数字进行排序，要实现这一点，就必须使用一个排序函数：
function sortNumber(a,b){
    return a - b;
}
var arr2 = new Array(6)
arr2[0] = "10"
arr2[1] = "5"
arr2[2] = "40"
arr2[3] = "25"
arr2[4] = "1000"
arr2[5] = "1"
console.log(arr2.sort(sortNumber));
//["1", "5", "10", "25", "40", "1000"]

//例3：根据数组对象中的某个属性值进行排序；
var arr = [
    {name:'zopp',age:0},
    {name:'gpp',age:18},
    {name:'yjj',age:8}
];
function compare(property){
    return function(a,b){
        var value1 = a[property];
        var value2 = b[property];
        return value1 - value2;
    }
}
console.log(arr.sort(compare('age')));



</script>
