使用 jQuery 删除脚本

I have a problem with my jQuery. So, I want to remove a script who is inside a <div>. My html is :

<div id="right-bloc">
        <div class="right-bloc-pub-1">
            <script type="text/javascript" src="http://firstScript.com"></script>
        </div>
        <div class="right-bloc-pub-2">
            <script type="text/javascript" src="http://secondScript.com"></script>
        </div>
</div>

我的 jQuery :

 var stringOfHtml = '<script type="text/javascript" src="http://firstScript.com"></script>';
 var html = $(stringOfHtml);
 html.find('script').remove();

html.find('script[src="http://firstScript.com"]').remove();
