as3数组按索引删除

Question

我有一个数组'猫'，'狗'，'笨蛋'

并希望按索引删除该项目。

目前我有

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

Answer 1

你想要拼接

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);
}

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
