高的PHP十期培训学习笔记

今天根据在PHP中文网所学的前端知识来完成一个商城购物车的页面的编写，这里参照的是京东的购物车。

参照页面

首先分析页面结构

其中购物车中的商品数量在实际使用情况中应该是不固定的，所以这里需要使用flex布局来写，使用列对齐的方式写出来一条，然后复制；

按照分板图写出HTML代码

  1. <!DOCTYPE html>
  2. <html lang="en">
  3. <head>
  4.     <meta charset="UTF-8">
  5.     <title>购物车</title>
  6.     <link rel="stylesheet" href="shop_public_Cart.css">
  7. </head>
  8. <body>
  9. <div class="shop-public-cart">
  10.         <!--    菜单和地址-->
  11.         <div class="nav-top">
  12.             <span>全部商品 3</span>
  13.             <div>
  14.                 <span>配送到：</span>
  15.                 <span>湖南省岳阳市岳阳楼区</span>
  16.             </div>
  17.         </div>
  18.         <!--    抬头-->
  19.         <div class="rise">
  20.         <span>
  21.             <input type="checkbox" id="all-Choice" checked>
  22.             <label for="all-Choice">全选</label>
  23.         </span>
  24.             <span>商品</span>
  25.             <span class="W120">单价</span>
  26.             <span class="W120">数量</span>
  27.             <span class="W120">小计</span>
  28.             <span class="W120">操作</span>
  29.         </div>
  30.         <!--    商品列表-->
  31.         <div class="list">
  32.             <div>

  86.         </div>
  88. </div>
  89. </body>
  90. </html>

增加公共样式后的效果

按顺序先写顶部的样式

  1. /*购物车*/
  2. .shop-public-cart {
  3.     width: 1200px;
  4.     margin: 30px auto;
  5.     background-color: #fff;
  6.     padding: 15px;
  7.     box-sizing: border-box;
  8. }
  9. /*菜单和地址*/
  10. .shop-public-cart > .nav-top {
  11.     display: flex;
  12.     justify-content: space-between;
  13.     height: 30px;
  14. }
  15. .shop-public-cart > .nav-top > span:first-of-type {
  16.     color: #E2231A;
  17.     font-size: 16px;
  18.     border-bottom: 1px solid #E2231A;
  19. }
  20. .shop-public-cart > .nav-top > div {
  21.     color: #666666;
  22. }
  23. .shop-public-cart > .nav-top > div > span:last-of-type {
  24.     border: 1px solid #CECBCE;
  25.     padding: 5px;
  26.     line-height: 23px;
  27. }

再写项目分类的样式

  1. /*公共宽度*/
  2. .W120 {
  3.     width: 120px;
  4. }
  6. /*抬头*/
  7. .shop-public-cart > .rise {
  8.     display: flex;
  9.     text-align: center;
  10.     background: #f3f3f3;
  11.     border: 1px solid #e9e9e9;
  12.     height: 32px;
  13.     align-items: center;
  14.     margin-bottom: 10px;
  15.     padding-left: 10px;
  16. }
  18. .shop-public-cart > .rise > span:nth-of-type(2) {
  19.     flex: 1;
  20. }

这里添加了一个宽度值，用于小项目的宽度定位，这样显示更整齐

商品列表的样式

  1. /*商品列表*/
  2. .shop-public-cart > .list {
  3.     display: flex;
  4.     flex-direction: column;
  5. }
  6. .shop-public-cart > .list > div {
  7.     height: 120px;
  8.     display: flex;
  9.     align-items: center;
  10.     background-color: #fef4e8;
  11.     border-bottom: 1px solid #999;
  12. }
  13. .shop-public-cart > .list > div img {
  14.     width: 80px;
  15.     height: 80px;
  16.     border: 1px solid #eee;
  17. }
  18. .shop-public-cart > .list > div > span {
  19.     padding: 10px;
  20.     box-sizing: border-box;
  21.     text-align: center;
  22. }
  23. .shop-public-cart > .list > div > span input {
  24.     width: 60px;
  25.     border: 1px solid #CECBCE;
  27. }
  28. .shop-public-cart > .list > div > span:nth-of-type(3) {
  29.     flex: 1;
  30. }

一条商品调试好后我们就可以在HTML代码中复制这个商品的代码，查看多条商品信息时的显示状态

没问题后我们继续写提交功能

  1.  /*结算*/
  2. .shop-public-cart > .buy {
  3.     border: 1px solid #e9e9e9;
  4.     height: 50px;
  5.     display: flex;
  6.     justify-content: end;
  7.     align-items: center;
  8.     margin-top: 20px;
  9. }
  10. .shop-public-cart > .buy > button {
  11.     width: 90px;
  12.     height: 50px;
  13.     font-size: 20px;
  14.     text-align: center;
  15.     line-height: 50px;
  16.     border: none;
  17.     color: white;
  18.     font-weight: 700;
  19.     background-color: #E2231A;
  20. }
  21. .shop-public-cart > .buy > span {
  22.     padding: 0 20px;
  23. }
  25. .shop-public-cart > .buy > span > a {
  26.     color: #E2231A;
  27.     font-weight: 700;
  28.     margin: 0 5px;
  29. }
