<h2>Complete String Object Reference</h2>
<p>
For a complete reference of all the properties and methods that can be used with
the String object, go to our <a href="../jsref/jsref_obj_string.asp">
complete String object reference</a>.</p>
<p>The reference contains a brief description and examples of use for each
property and method!</p>

<h2>String object</h2>
<p>The String object is used to manipulate a stored piece of text.</p>
<p><b>Examples of use:</b></p>
<p>The following example uses the length property of the String object to find
the length of a string:</p>
<table class="ex" cellspacing="0" border="1" width="100%" id="table8">
<tr>
<td>
<pre>var txt="Hello world!";
document.write(txt.length);</pre>
</td>
</tr>
</table>
<p>The code above will result in the following output:</p>
<table class="ex" cellspacing="0" border="1" width="100%" id="table9">
<tr>
<td>
<pre>12</pre>
</td>
</tr>
</table>
<p>The following example uses the toUpperCase() method of the String object to
convert a string to uppercase letters:</p>
<table class="ex" cellspacing="0" border="1" width="100%" id="table1">
<tr>
<td>
<pre>var txt="Hello world!";
document.write(txt.toUpperCase());</pre>
</td>
</tr>
</table>
<p>The code above will result in the following output:</p>
<table class="ex" cellspacing="0" border="1" width="100%" id="table10">
<tr>
<td>
<pre>HELLO WORLD!</pre>
</td>
</tr>
</table>
