AS3对数组进行Push, Pop, Unshift 和 Shift 等操作的代码

var myArray:Array = new Array();
 
 
// PUSH
// Adds one or more elements to the end of an array and returns the new length of the array.
myArray = ["a","b","c","d"];
trace(myArray);
myArray.push("e");
trace(myArray);
// OUTPUT
// a,b,c,d
// a,b,c,d,e
 
 
// POP
// Removes the last element from an array and returns the value of that element.
myArray = ["a","b","c","d"];
trace(myArray);
myArray.pop();
trace(myArray);
// OUTPUT
// a,b,c,d
// a,b,c
 
 
// UNSHIFT
// Adds one or more elements to the beginning of an array and returns the new
// length of the array. The other elements in the array are moved from their 
// original position, i, to i+1.
myArray = ["a","b","c","d"];
trace(myArray);
myArray.unshift("_");
trace(myArray);
// OUTPUT
// a,b,c,d
// _,a,b,c,d
 
 
 
// SHIFT
// Removes the first element from an array and returns that element.
// The remaining array elements are moved from their original position, i, to i-1.
myArray = ["a","b","c","d"];
trace(myArray);
myArray.shift();
trace(myArray);
// OUTPUT
// a,b,c,d
// b,c,d
