as3 array按索引刪除

Question

我有一個數組'貓'，'狗'，'budgie'

並希望通過索引刪除項目。

目前，我有

function removeit(myindex) { 
    animals[myindex] = animals.pop() 
} 

Answer 1

你想拼接

http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/Array.html#splice%28%29

方法Array.splice（起點，取出計數）;

var newArray:Array = myArray.splice(2, 1); //this removes whatever is at index 2 and returns it in a new array. 

更改您要

function removeit(myindex) { 
    animals.splice(myindex, 1); 
} 

Answer 2

功能當使用Flash Player 19+或19+ AIR，您可以使用

myArray.removeAt(myIndex); // removes the element at the specified index, modifying the array without making a copy
