我有一个数组“猫”、“狗”、“鹦鹉”

并希望按索引删除项目。

目前我有

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

你想要拼接

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

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.

将您的功能更改为

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

使用 Flash Player 19+ 或 AIR 19+ 时,您可以使用

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