as3数组按索引删除

Question

我有一个阵列'猫','狗','budgie'

并希望按索引删除该项目.

目前我有

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

Answer 1

你想拼接

Array.splice(起始点,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);
}

Answer 2

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
