<p class="desc"><strong>Description: </strong>Merge the contents of two arrays together into the first array. </p>
<ul class="signatures"><li class="signature" id="jQuery-merge-first-second">
<h4 class="name">
<span class="versionAdded">version added: <a href="/category/version/1.0/">1.0</a></span>jQuery.merge( first, second )</h4>
<p class="arguement"><strong>first</strong>The first array to merge, the elements of second added.</p>
<p class="arguement"><strong>second</strong>The second array to merge into the first, unaltered.</p>
</li></ul>
<div class="longdesc">
<p>The <code>$.merge()</code> operation forms an array that contains all elements from the two arrays. The orders of items in the arrays are preserved, with items from the second array appended. The <code>$.merge()</code> function is destructive. It alters the first parameter to add the items from the second. </p>
<p>If you need the original first array, make a copy of it before calling <code>$.merge()</code>. Fortunately, <code>$.merge()</code> itself can be used for this duplication:</p>
<pre>var newArray = $.merge([], oldArray);</pre>
<p>This shortcut creates a new, empty array and merges the contents of oldArray into it, effectively cloning the array.</p>
<p>Prior to jQuery 1.4, the arguments should be true Javascript Array objects; use <code>$.makeArray</code> if they are not.</p>

<div id="example-0">
<h4>Example: <span class="desc">Merges two arrays, altering the first argument.</span>
</h4>
<pre class="prettyprint"><code class="example">$.merge( [0,1,2], [2,3,4] )</code></pre>
<h4>Result:</h4>

<div id="example-1">
<h4>Example: <span class="desc">Merges two arrays, altering the first argument.</span>

<h4>Result:</h4>
<pre><code class="results">[3,2,1,4,3,2] </code></pre>
</div>
<div id="example-2">
<h4>Example: <span class="desc">Merges two arrays, but uses a copy, so the original isn't altered.</span>
</h4>
<pre class="prettyprint"><code class="example">var first = ['a','b','c'];
var second = ['d','e','f'];
$.merge( $.merge([],first), second);
</code></pre>
