JavaScript 做了个实验的,学习sort 函数,有错,我也不会改,求改!
<code>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; } } </code>
