以下为该购物车的效果图，能够对购物车中的商品进行勾选/全选、商品的自增自减、自动结算功能以及单独删除和批量删除的功能。
下列为代码具体步骤解说（搭建完结构的基础上）：
1.通过for循环输出数组中的对象并填充到html结构中，在循环的时候加入index索引为了方便删除单条数据的时候更快的找到该条数据在数组中对应的位置。将input绑定item.pro_num，然后自增自减只需要判断item.pro_num--或者是item.pro_num++即可；在判断输入框中的数值时顺带计算该条内容的总价，即为item.pro_num*item.pro_price;
js:
2.由于后台在给数据的时候并不会标记该条记录是否被选中，所以我们自己在mounted中给productList加一个select属性来表示是否勾选，每条内容则可添加@click="item.select=!item.select"来进行选中和取消选中的效果，选中的添加一个select_true类名。
3.当select属性有了，就可以判断全选了：
用一个isSelectAll来判断是否全选，如果productList的长度为0的话，则返回false不全选；然后通过every来逐个判断select是否为true，如果为true的话，则全选；
点击全选时，通过for循环来遍历出所有的select，使所有的select = !isSelectAll
4.再来就是勾选的数目以及所有的总价的计算了
5.最后，剩下删除功能，删除单个的话，很简单，只需要找到对应的index索引，然后通过splice（）则可轻松实现；批量删除的话，则需要找到数组中select=false的数据，然后将productList数据替换为select=false的数据即可。
功能的解说已经完成了，最后贴上详细代码~
