<h1>JavaScript match() Method</h1>
<hr />
<a href="jsref_obj_string.asp"><img class="navup" src="../images/up.gif" alt="String Object Reference" border="0" /> Complete String Object Reference</a>
<hr />
<h2>Definition and Usage</h2>
<p>The match() method searches for a specified
value in
a string.</p>
<p>This method is similar to indexOf() and lastIndexOf(), but it returns the specified
value, instead of the position of the string.</p>
<h2>Syntax</h2>
<table class="ex" cellspacing="0" border="1" width="100%">
<tr>
<td>
<pre>stringObject.match(searchvalue)</pre>
</td>
</tr>
</table>
<br />
<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3">
<tr>
<th align="left" valign="top" width="20%">Parameter</th>
<th align="left" valign="top" width="80%">Description</th>
</tr>
<tr>
<td valign="top">searchvalue</td>
<td valign="top">Required. Specifies a string value to search for</td>
</tr>
</table>
<br />
<hr />
<h2>Tips and Notes</h2>
<p><b>Note:</b> The match() method is case sensitive!</p>
<p><b>Note:</b> This method returns <i>null</i> if the string value to search for never
occurs.</p>
<hr />
<h2>Example</h2>
<p>In this example we will do different searches within a "Hello world!" string:</p>
<table class="ex" cellspacing="0" border="1" width="100%">
<tr>
<td>
<pre><script type="text/javascript"></pre>
<pre>var str="Hello world!";
document.write(str.match("world") + "<br />");
document.write(str.match("World") + "<br />");
document.write(str.match("worlld") + "<br />");
document.write(str.match("world!"));</pre>
<pre></script></pre>
</td>
</tr>
</table>
<p>
The output of the code above will be:</p>
<table class="ex" cellspacing="0" border="1" width="100%">
<tr>
<td>
<pre>world
null
null
world!</pre>
</td>
</tr>
</table>
