1.全选很简单，根据全选checkbox的选中状态来控制其它checkbox就行。if语句里是我控制结算按钮的css的。可不用理会。
2.计算价格同理，给所有的checkbox添加一个class，把价格通过自定义标签写在checkbox元素上，当点击任意class名为sumprice的时候就触发点击事件，循环所有checkbox，然后获取价格为真的值，累计相加。
3.全选某个店铺，sel_quan(obj)方法，给店铺的checkbox定义一个唯一class，子checkbox也加上这个唯一class，当选中店铺checkbox的时候，就把带有这个标识的产品checkbox都选中。
<script type="text/javascript">$(function(){$(".chooseall").click(function(){ var isChecked = $(this).prop("checked");if(isChecked==true){$('.cart-btn').removeClass('cartnull');$('.cart-btn').addClass('cartctrue');}else{$('.cart-btn').removeClass('cartctrue');$('.cart-btn').addClass('cartnull');}$("input[type='checkbox']").prop("checked", isChecked);});$('.sumprice').click(function(){var totalprice = 0;$('.sumprice').each(function(){if ($(this).is(":checked")) {var aaa = parseInt($(this).attr('data-price'));if(aaa){totalprice += aaa;}}if(totalprice==0){$('.cart-btn').removeClass('cartctrue');$('.cart-btn').addClass('cartnull');}else{$('.cart-btn').removeClass('cartnull');$('.cart-btn').addClass('cartctrue');}$('.ctotal').text(totalprice.toLocaleString());});});})var btn=document.getElementById('cartEdit'); btn.addEventListener('click',function(){$('#cartDelete').fadeIn(1000);document.getElementById("cartEdit").style.display="none";document.getElementById("cartFinish").style.display="";},false);var btn2=document.getElementById('cartFinish'); btn2.addEventListener('click',function(){$('#cartDelete').fadeOut(1000);$('#cartEdit').fadeIn(1000);document.getElementById("cartFinish").style.display="none";},false);function sel_quan(sellerid){$(".zimulu_"+sellerid).prop("checked",$(".father_"+sellerid).prop("checked"));}</script>以上代码还没有很完善，比如当checkbox没有全部选中的时候，全选按钮状态取消，店铺产品没有全部选中的时候，状态取消等等，我就懒的弄了。
样式我就不贴了，毕竟js是最重要的，只要把需要的class名放在你要的标签上就行了
js购物车全选反选、商品价格统计
