注：用的不是form標(biāo)簽下的元素 類似這種的：<div class="div1"><ul class="ul_1"><li><a href="javascript:void(0);"><span class="frind_name">張三</span></a><p>對號</p></li><li><a href="javascript:void(0);"><span class="frind_name">李四</span></a><p>對號</p></li><li><a href="javascript:void(0);"><span class="frind_name">王二</span></a><p>對號</p></li><li><a href="javascript:void(0);"><span class="frind_name">麻子</span></a><p>對號</p></li></ul></div><div class="div2"><span class="num">0</span><ul class="ul_2"></ul></div>
