AS3阵列由索引中删除(as3 array remove by index)

我有一个数组“猫”，“狗”，“鹦鹉”

并想索引中删除该项目。

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（起点，删除计数）;

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

更改功能

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

Answer 2:

当使用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
