jsFiddle - 我有2个阵列。我想将第二个变量设置为第一个变量的排序版本。
var _myArray = ["N","T","A","W","Z","X"];
var _array02 = _myArray.sort();
document.write(_myArray+'<br>'+_array02);
应该发生什么:N,T,A,W,N,X<br>A,N,T,W,X,Z
反而会发生什么:A,N,T,W,X,Z<br>A,N,T,W,X,Z
这是JS的设计,如果是这样,我如何实现我的目标?

sort()
对数组进行排序。如果您希望原始数组保持不变,请对副本进行排序:
var _myArray = ["N","T","A","W","Z","X"];
var _array02 = _myArray.slice().sort();
_myArray +'\n'+_array02
/* returned value: (String)
N,T,A,W,Z,X
A,N,T,W,X,Z
*/
