var arr3 =new Array("xxxx510","xxxx12","xxxx16","xxxx18","xxxx13","xxxx14","xxxx15","xxxx8","xxxx7","xxxx6","xxxx1","xxxx5",2 );
arr3.sort(Nat123);
console.log(arr3.toString());
function Nat123(a,b) //自然数升序
{
var aa=a.replace( "xxxx" , "" );
var bb=b.replace( "xxxx" , "" );
if(aa==bb)
{
return 0;
}
else if(aa>bb)
{
return 1; //1 就是第2个在前;
}
else
{
return -1; //-1 就是第1个在前;
}
}
JavaScript 做了个实验的,学习sort 函数,有错,我也不会改,求改!
