                                 <a class="m_icon m_icon_delete_gray right" giftid="1"  id="js-delcar"></a>
                            </label>
                            <div class="img_type">
                                <img class="img180" src="/201409/09/M29753_491_p_thumb_120120.jpg">

                            <p class="numbox">
                                <a class="del lessclick">-</a>

                        <div class="price">
                            <input type="hidden" name="business[self][items][7716355600][sizeid]" value="560"/>
                            <span class="oof"></span>
                            <span class="js-price">100</span><br/>
                            <del><span class="oof">￥</span>199.00</del><br/>
                        </div>
                        <div class="clear"></div>
                    </li>

                        求大神如何在lessclick的click事件中获取class为js-price的值（即100）



    $('.lessclick').click(function () {
                        /**在这里通过this获得**/
                        /**下面为我写的却不对**/
                        alert($(this).parents().next().first().text());
    });

你选的元素不对，$(this).parents().next().first()并不能选中class为js-price的元素，你可以这样选择$(this).parents().parents().next().find(".js-price")
