How to get query string from the URL
<p>My Page name is index.php and its contain some links(internal page link) and contents. on the click of link I m applying <code>"selected" class</code> on link <code>li</code> and showing related contents and my page link change from index.php to index.php#c2 (or #c3, #c4, c1 for other ids). </p>

<p>My problem is on the page load. If I give this link in other page eg. in <code>page.php</code> I given like this <code>&lt;li&gt;&lt;a href="index.php?#c2"&gt;link2&lt;/a&gt;&lt;/li&gt;</code> then how could I know that <code>#c2</code> is passed in URL based on this I want to apply the <code>"selected" class</code> to <code>li</code>. I tried it by <code>$_SERVER</code> but not done. I am not able to get the string after "?".</p>

<p>Pls tell me if there is any other way to do this..</p>

<pre><code>&lt;li class="selected"&gt;&lt;a href="#c1"&gt;link1&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;&lt;a href="#c2"&gt;link2&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;&lt;a href="#c3"&gt;link3&lt;/a&gt;&lt;/li&gt;
&lt;li&gt;&lt;a href="#c4"&gt;link4&lt;/a&gt;&lt;/li&gt;

&lt;div id="c1"&gt;&lt;!-- contents of link1 --&gt;&lt;/div&gt;
&lt;div id="c2"&gt;&lt;!-- contents of link2 --&gt;&lt;/div&gt;
&lt;div id="c3"&gt;&lt;!-- contents of link3 --&gt;&lt;/div&gt;
&lt;div id="c4"&gt;&lt;!-- contents of link4 --&gt;&lt;/div&gt;
</code></pre>

<p>Jquery code to add selected class</p>

<pre><code>$('.links a').click(function(){
    $('.links  a').parent().removeClass('selected');
    $(this).parent().addClass('selected');  
});
</code></pre>

<p>Thanks in advance..</p>
