arrays - as3数组按索引删除

Question

我有一个数组“cat”、“dog”、“budgie”

并且想要通过索引删除该项目。

目前我已经

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);
}
