购物车里的功能无非是商品数量的加减、商品删除、全选反选等操作,其实现过程如下所示:
1.html代码:
<body> <div class="empty"> 购物车空空如也,<a href="javascript:void(0);" >快去选购吧</a> </div> <table border="2px solid #ccc" id="table"> <thead> <th> <input type="checkbox" class="checkOnly" style="vertical-align:middle;margin-right:20px;">全选 </th> <th>序号</th> <th>商品名称</th> <th>数量</th> <th>单价</th> <th>小计</th> <th>操作</th> </thead> <tbody> <tr> <td> <input type="checkbox" class="check"> </td> <td class="num">1</td> <td>烤煎饼</td> <td> <span> <input type="button" value="-" class="reduces"> <span class="span">1</span> <input type="button" value="+" class="adds"> </span> </td> <td>单价: <span class="price">2</span> </td> <td> 小计: <span class="prices">2</span> </td> <td> <a href="#" class="del">删除</a> </td> </tr> <tr> <td> <input type="checkbox" class="check"> </td> <td class="num">2</td> <td>珍珠奶茶</td> <td> <span> <input type="button" value="-" class="reduces"> <span class="span">1</span> <input type="button" value="+" class="adds"> </span> </td> <td>单价: <span class="price">4</span> </td> <td> 小计: <span class="prices">4</span> </td> <td> <a href="#" class="del">删除</a> </td> </tr> <tr> <td> <input type="checkbox" class="check"> </td> <td class="num">3</td> <td>水煮鱼</td> <td> <span> <input type="button" value="-" class="reduces"> <span class="span">1</span> <input type="button" value="+" class="adds"> </span> </td> <td>单价: <span class="price">20</span> </td> <td> 小计: <span class="prices">20</span> </td> <td> <a href="#" class="del">删除</a> </td> </tr> <tr> <td> <input type="checkbox" class="check"> </td> <td class="num">4</td> <td>蛋糕</td> <td> <span> <input type="button" value="-" class="reduces"> <span class="span">1</span> <input type="button" value="+" class="adds"> </span> </td> <td>单价: <span class="price">50</span> </td> <td> 小计: <span class="prices">50</span> </td> <td> <a href="#" class="del">删除</a> </td> </tr> <tr> <td> <input type="checkbox" class="check"> </td> <td class="num">5</td> <td>土豆片</td> <td> <span> <input type="button" value="-" class="reduces"> <span class="span">1</span> <input type="button" value="+" class="adds"> </span> </td> <td>单价: <span class="price">5</span> </td> <td> 小计: <span class="prices">5</span> </td> <td> <a href="#" class="del">删除</a> </td> </tr> <tr> <td> <input type="checkbox" class="check"> </td> <td class="num">6</td> <td>蛋黄派</td> <td> <span> <input type="button" value="-" class="reduces"> <span class="span">1</span> <input type="button" value="+" class="adds"> </span> </td> <td>单价: <span class="price">5.5</span> </td> <td> 小计: <span class="prices">5.5</span> </td> <td> <a href="#" class="del">删除</a> </td> </tr> <tr> <td colspan="7" class="talast"> <span>商品一共 <span class="goods_num" style="color:red;font-size:20px;">0</span> 件; 共计花费 <span class="pricetal" style="color:red;font-size:20px;">0</span> 元; 其中最贵的商品单价是 <span class="pricest" style="color:red;font-size:20px;">0</span> 元</span> </td> </tr> </tbody> </table> </body>
2.css代码:
<style type="text/css"> table { width: 1000px; /* height: 300px; */ border-collapse: collapse; table-layout: fixed; text-align: center; font-size: 18px; margin: 0 auto; } a { text-decoration: none; color: black; } tr { height: 50px; } .check { width: 20px; height: 20px; } .checkOnly { width: 20px; height: 20px; } .empty { font-size: 25px; position: fixed; top: 45%; left: 45%; display: none; } .empty a { color: pink; } .empty a:hover { text-decoration: underline; } </style>
3.js代码:
<script src="/UploadFiles/2021-04-02/jquery-1.8.3.min.js">补充上面js代码中用到的全选反选插件 \color{red}{补充上面js代码中用到的全选反选插件}补充上面js代码中用到的全选反选插件
//1、定义全选的插件 jQuery.fn.extend({ bindCheck:function($subCheckBox,$btnUncheck){ let $allCheckBox = this; //1、给全选复选框绑定click事件 //this:是全选复选框(jQuery对象) this.click(function(){ let isChecked = this.checked; $subCheckBox.each(function(){ this.checked = isChecked; }); }); //2、给反选 if(arguments.length==2){ $btnUncheck.click(function(){ $subCheckBox.each(function(){ this.checked = !this.checked; }); reversCheck(); }); } //3、给每个选择项的复选框绑定事件 $subCheckBox.click(function(){ reversCheck(); }); function reversCheck(){ //1、判断是否全部的复选框被选中 let isAllChecked = true; $subCheckBox.each(function(){ if(!this.checked){ isAllChecked = false; } }); //2、处理全选复选框 $allCheckBox.attr("checked",isAllChecked); } } });效果如下图所示:
