To merge (concatenate) arrays, use <code>.concat()</code>.

Below are two examples of how you can concatenate arrays and remove duplicates at the same time.

More convenient way: (you can use <code>ArrayUtil.createUniqueCopy()</code> from <a href="http://code.google.com/p/as3corelib/" rel="noreferrer">as3corelib</a>)

<pre><code>// from as3corelib:
import com.adobe.utils.ArrayUtil;

var a1:Array = ["a", "b", "c"];
var a2:Array = ["c", "b", "x", "y"];

var c:Array = ArrayUtil.createUniqueCopy(a1.concat(a2)); // result: ["a", "b", "c", "x", "y"]
</code></pre>

Slightly faster way: (you can loop through the arrays yourself and use <a href="http://livedocs.adobe.com/flex/3/langref/Array.html#indexOf()" rel="noreferrer"><code>Array.indexOf()</code></a> to check for duplicates)

<pre><code>var a1:Array = ["a", "b", "c"];
var a2:Array = ["c", "b", "x", "y"];
var a3:Array = ["a", "x", "x", "y", "z"];

var c:Array = arrConcatUnique(a1, a2, a3); // result: ["a", "b", "c", "x", "y", "z"]

private function arrConcatUnique(...args):Array
{
 var retArr:Array = new Array();
 for each (var arg:* in args)
 {
 if (arg is Array)
 {
 for each (var value:* in arg)
 {
 if (retArr.indexOf(value) == -1)
 retArr.push(value);
 }
 }
 }
 return retArr;
}
</code></pre>

blocks|key|1461627|text|这是一种易于编写的简单算法。如果在Actionscript中有更直接的方法来实现这一点，我会很惊讶。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1461628|function+merge(a1:Array,+a2:Array):Array+{

This is kind of an simple algorithm to write. I would be surprised if there were a more direct way to do this in Actionscript.

<pre><code>function merge(a1:Array, a2:Array):Array {
 var result:Array = [];
 var i1:int = 0, i2:int = 0;

 while (i1 &lt; a1.length &amp;&amp; i2 &lt; a2.length) {
 if (a1[i1] &lt; a2[i2]) {
 result.push(a1[i1]);
 i1++;
 } else if (a2[i2] &lt; a1[i1]) {
 result.push(a2[i2]);
 i2++;
 } else {
 result.push(a1[i1]);
 i1++;
 i2++;
 }
 }

 while (i1 &lt; a1.length) result.push(a1[i1++]);
 while (i2 &lt; a2.length) result.push(a2[i2++]);

 return result;
}
</code></pre>

++++++++++++_array.splice(i--,+1);

}|type|code-block|depth|inlineStyleRanges|entityRanges|data|syntax|javascript|1676786|然后，对于"merge“，使用concat。例如：|unstyled|1676787|var+testArray:Array+=+[1,+1,+1,+5,+4,+5,+5,+4,+7,+2,+3,+3,+6,+5,+8,+5,+4,+2,+4,+5,+1,+2,+3,+65,+5,+5,+5,+5,+8,+4,+7];

testArray.concat(testArray2);
trace(testArray);
remDuplicates(testArray);
trace(testArray);|1676788|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$B|C]]|$1|D|3|E|5|F|7|L|8|@]|9|@]|A|$]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$B|C]]|$1|I|3|-4|5|F|7|N|8|@]|9|@]|A|$]]]|J|$]]

<pre><code>function remDuplicates(_array:Array):void{
 for (var i:int = 0; i &lt; _array.length;++i) {
 var index:int = _array.indexOf(_array[i]);
 if (index != -1 &amp;&amp; index != i) {
 _array.splice(i--, 1);
 }
 }
}
</code></pre>

Then for the "merge" use concat.
exemple :

<pre><code>var testArray:Array = [1, 1, 1, 5, 4, 5, 5, 4, 7, 2, 3, 3, 6, 5, 8, 5, 4, 2, 4, 5, 1, 2, 3, 65, 5, 5, 5, 5, 8, 4, 7];
var testArray2:Array = [1, 1, 1, 5, 4, 5, 5, 4, 7, 2, 3, 3, 6, 5, 8, 5, 4, 2, 4, 5, 1, 2, 3, 65, 5, 5, 5, 5, 8, 4, 7];

testArray.concat(testArray2);
trace(testArray);
remDuplicates(testArray);
trace(testArray);
</code></pre>

What's a nice way to merge two sorted arrays in ActionScript (specifically ActionScript 3.0)? The resulting array should be sorted and without duplicates.

Cleanly merge two arrays in ActionScript (3.0)?

在ActionScript (特别是ActionScript 3.0)中合并两个有序数组的好方法是什么？生成的数组应该排序，并且没有重复项。
