现状是textarea内输入文本，只能输满一行了自动换行，回车就触发accordion,没法换行。求解应该怎么处理，谢谢！

下面是html:

       <p id="accordion"> 
           <textarea class="textBox emotion" id="shareText" placeholder="发表一条分享......"></textarea>
            <p>
                <p class="area_commenter" >
                    <ul>
                        <li class="area area_commenter_current" id="area"><a>发送范围</a></li>
                        <li class="feedBack" id="feedShow"><input type="checkbox" id="feedBack" name="checkbox">回执</li>
                        <li class="commenter hide" id="commenterShow"><a>点评人</a></li>
                    </ul>

                </p>
            </p>
        </p>
        

以下是jquery：

$("#accordion").accordion({
    active:3,
    collapsible: true,
    event:"mouseover"
});
