如何在javascript中运行javascript

如何运行此javascript：

<script type='text/javascript'>
//<![CDATA[FANS='****'//]]>
</script>
<style>#fblikepop{background-color:#fff;display:none.....</style>
<script src='/facebookpop/jquery.js' type='text/javascript'></script>
<script src='http://connect.facebook.net/en_US/all.js#xfbml=1' type='text/javascript'></script>
<script src='/facebookpop/mbtlikebox2.js' type='text/javascript'></script>
<script language='javascript'>
//<![CDATA[
    $(document).ready(function(){                       
        $().FANS({
            timeout: 30,
            wait: 0,
            url: 'http://www.facebook.com/****',
            closeable: true     });
    });
//]]></script><div id='fbtpdiv'></div>

在这一方，JavaScript处于++++第二个JavaScript+++位置

<script type="text/javascript">
if(document.cookie.search(/(^|;)facebookpopc=/) > -1) {
    return false;
} else {

    ++++2nd JAVASCRIPT++++

}
</script>

多谢各位

} else {
    $(document).ready(function(){                       
        $().FANS({
            timeout: 30,
