Magento load jquery if before doesn't have loaded

Question

Answer 1

I think you can solve this way. But i think this is dirty way to achieve this

I check in head.phtml and its working for me

<?php
    $jsget= $this->getCssJsHtml();//all magento js/css store in $jsget variable
    $jquertcheck=strpos($jsget, 'jquery');

//and check with jquery word contain or not or you can find more possibility qith jquery word

Where $this is Mage_Page_Block_Html_Head block

if($jquertcheck==false) { ?>

// if it doesn't contain jquery word then you can include jquery

<script src="<?php echo $this->getSkinUrl("js")?>/jquery.js" type="text/javascript"></script>
<?php
}

?>

Let me know if it works or not .

I think someone can post other solution to achieve this
