跟蹤數組符合以下標準的方法有哪些？

Question

數組：

var numberArray:Array= new Array(34,53,2,3,34,26,26,85,3,4,98,2,12); 

1. 如何跟蹤它，以便輸出面板將顯示所有其他項目："34,2,34,26,3,98,12"

2. 如何跟蹤具有比10的較低值的數字

3. 如何追蹤數組中的偶數？

Answer 1

對於基準和總體教育：http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/Vector.html#map()

// You can init Arrays with [] operator. 
var numberArray:Array = [34,53,2,3,34,26,26,85,3,4,98,2,12]; 

trace(filter(numberArray, evenIndices)); 
trace(filter(numberArray, belowTen)); 
trace(filter(numberArray, evenValues)); 

// In AS3 you can pass method references as function arguments. 
// That allows to compose a filtering method, just like Vector.map(...) 

// This method will filter the original array 
// by the given criteria and return the filtered result. 
// Criteria method must accept 2 arguments: element index and value. 
function filter(source:Array, criteria:Function):Array 
{ 
    var result:Array = new Array; 

    for (var i:int = 0; i < source.length; i++) 
     if (criteria(i, source[i])) 
      result.push(source[i]); 

    return result; 
} 

// Returns true if index is an even number. 
function evenIndices(index:int, value:int):Boolean 
{ 
    return index % 2 == 0; 
} 

// Returns true if value is less than 10. 
function belowTen(index:int, value:int):Boolean 
{ 
    return value < 10; 
} 

// Returns true if value is an even number. 
function evenValues(index:int, value:int):Boolean 
{ 
    return value % 2 == 0; 
} 

Answer 2

VAR numberArray：數組= [34，53，2，3，34，26，26，85];

1.How我跟蹤它使輸出面板將顯示每隔一個項目：「34,2,34,26,3,98,12」

getEventIndexiesOfArray(numberArray); 

2.How做我跟蹤具有比10更低的值的數字

lenghtLessthanTen(numberArray); 

3.如何跟蹤數組中的偶數？

checkArrayHasEventLenght(numberArray); 

1. getEventIndexiesOfArray（），用於從陣列獲取事件indexies元件方法。

private function getEventIndexiesOfArray(source:Array):void 
     { 
      var resultArr:Array = []; 
      for (var i:int = 0; i < source.length; i++) 
      { 
       if (i % 2 == 0) 
        resultArr.push(source[i]); 
      } 
      trace("Even Indexies Array : " + resultArr.toString()); 
     } 

2. lenghtLessthanTen（）方法用於檢查該陣列lenght是每種不超過10與否。

private function lenghtLessthanTen(source:Array):void 
      { 
       if (source.length < 10) 
        trace("Array containt lessthan Ten elements"); 
      } 

3. checkArrayHasEventLenght（）方法檢查陣列containt甚至lenght與否。

private function checkArrayHasEventLenght(source:Array):void 
     { 
      if (source.length % 2 == 0) 
       trace("Array has even number of elenter code hereements"); 
     }
