不知道可否有人試過(guò)復制多維數組變量后，修改原來(lái)的數組變量，而拷貝的變量值也一起更換呢？
如：
var = new Array([1,2]);
var = myArray;
myArray[0][0] = 3;
trace(myArray); //3,2
trace(temp); //沒(méi)更動(dòng)但卻輸出3,2
var = myArray;
myArray[0][0] = 3;
trace(myArray); //3,2
trace(temp); //沒(méi)更動(dòng)但卻輸出3,2
而經(jīng)過(guò)測試之后，在一維數組卻沒(méi)有問(wèn)題。所以從此處寫(xiě)出修正的方法
Array.prototype.duplicate = function(){
var a = [];
for (var i in this) (this[i] instanceof Array) ? a[i] = this[i].slice() : a[i] = this[i];
return a;
}
var = new Array();
myArray[0]=[1,2]
myArray[1]=3
myArray[2]=[5,6]
var = myArray.duplicate();
trace(myArray); //1,2,3,5,6
trace(temp); //1,2,3,5,6
myArray[0][0] = 5;
trace(myArray); //5,2,3,5,6
trace(temp); //1,2,3,5,6
var a = [];
for (var i in this) (this[i] instanceof Array) ? a[i] = this[i].slice() : a[i] = this[i];
return a;
}
var = new Array();
myArray[0]=[1,2]
myArray[1]=3
myArray[2]=[5,6]
var = myArray.duplicate();
trace(myArray); //1,2,3,5,6
trace(temp); //1,2,3,5,6
myArray[0][0] = 5;
trace(myArray); //5,2,3,5,6
trace(temp); //1,2,3,5,6
