jQuery插件开发发送短信倒计时功能代码

<input type="button" class="sameBtn btnCur" value="发送验证码"/><div class="sameBtn btnCur2">发送验证码</div>

body{padding:100px;text-align: center;}.sameBtn{display: inline-block;font-size:12px;cursor:pointer;width:76px;height:25px;line-height: 25px;text-align: center;border:0;background: #3186df;color:#fff;}.sameBtn.current{background: #b1b1b1;}
