Jquery怎样获取标签的值？

<div class="aw-item">
<div class="mod-head">
<h4><a href="http://site.com/site">标题</a></h4>
</div>
<div class="mod-body clearfix">
<!-- 内容 -->
<div class="markitup-box">
内容。。。</div>
<!-- end 内容 -->
</div>
<div class="mod-footer">
<!-- Social -->
<div class="meta clearfix">
<a class="text-color-999 dropdown-toggle" data-toggle="dropdown">
<i class="icon icon-share"></i>分享</a>
<div aria-labelledby="dropdownMenu" role="menu" class="aw-dropdown shareout pull-right">
<ul class="aw-dropdown-list">
<li><a onclick="AWS.User.share_out('facebook', 获取标题.text(), 'http://site.com/site');"><i class="icon icon-facebook"></i> facebook</a></li>
</ul>
</div>
</span>
</div>
<!-- end Social -->
</div>
</div>

请问一下<a onclick="AWS.User.share_out('facebook', 获取标题.text(), 'http://site.com/site');"><i class="icon icon-facebook"></i> facebook</a>从这a标签的位置怎样获取标题的值(h4标签里面a标签的值)
