pass a parameter from the URL using Javascript

Hi,

Does anyone know how to pass a parameter from the URL?

I declare my parameter at the top of the xsl stylesheet, like that:
<xsl:param name="page_number" select=" 1 "/>
iI change the select value and i get the h2 that i want.

My xml file looks like that:

        <div class="section">
                        <h2>Chris</h2>
                        <p>text</p>
                        <p>text</p>
                </div>
                <div class="section">
                        <h2>
                                <a href="http://www.mypage.com";>Leo</a>
                        </h2>
                </div>
                <div class="section">
                        <h2>George</h2>
                        <p>text</p>
                </div>
                <div class="section">
                        <h2>Alex</h2>
                        <p>text</p>
                        <p>text</p>
                </div>


In my xsl i have this template witch i pick-up the desired h2 each time:

<xsl:template 
match="//xhtml:div[(_at_)class='section'][position()=$page_number]/xhtml:h2/*">
<xsl:when test="//xhtml:div[(_at_)class='section'][position()=$page_number]">
</xsl:template>

I found something like:

<script>

var page_number = location.search.substr(1).split("?");

</script>


but no luck...

Cheers

Leo
