layui数据表格实现类购物车功能



使用方法

1：单击左边商品列表任一商品，右边购物车数据表格会渲染一条数据，同时计算总数，合计金额。
2：购物车数据表格，数量/单价改变，金额改变，底部合计金额，数量，也会跟随改变
3：购物车数据表格，‘删除'，删除当前所选商品

*{ margin:0; padding:0; } #guide_panel{ width:98%; margin:0auto; } #row_panel{ width:98%; height:720px; margin:0auto; /*border:solid1pxred;*/ } #row_panel.table-panel{ width:50%; height:500px; float:left; text-align:center; } #row_panel.table-panelp{ color:#BBBBBB; } #row_panel.bottom-panel{ width:100%; height:40px; background:#F0F0F0; float:left; margin-top:20px; text-align:right; } #row_panel.bottom-panelspan{ line-height:40px; font-size:18px; }
