thymeleaf公共页面元素抽取
1、抽取公共片段 <div th:fragment="copy"> © 2011 The Good Thymes Virtual Grocery </div> 2、引入公共片段 <div th:insert="~{footer :: copy}"></div> ~{templatename::selector}：模板名::选择器
~{templatename::fragmentname}:模板名::片段名
3、默认效果：
insert的公共片段在div标签中
如果使用th:insert等属性进行引入，可以不用写~{}：
行内写法可以加上：[[~{}]];[(~{})]；
三种引入公共片段的th属性：
th:insert：将公共片段整个插入到声明引入的元素中
th:replace：将声明引入的元素替换为公共片段
th:include：将被引入的片段的内容包含进这个标签中
<footer th:fragment="copy"> © 2011 The Good Thymes Virtual Grocery </footer> 引入方式 <div th:insert="footer :: copy"></div> <div th:replace="footer :: copy"></div> <div th:include="footer :: copy"></div> 效果 <div> <footer> © 2011 The Good Thymes Virtual Grocery </footer> </div> <footer> © 2011 The Good Thymes Virtual Grocery </footer> <div> © 2011 The Good Thymes Virtual Grocery </div>
引入片段的时候传入参数：
<nav class="col-md-2 d-none d-md-block bg-light sidebar" id="sidebar"> <div class="sidebar-sticky"> <ul class="nav flex-column"> <li class="nav-item"> <a class="nav-link active" th:class="${activeUri=='main.html'?'nav-link active':'nav-link'}" href="#" th:href="@{/main.html}"> <svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" class="feather feather-home"> <path d="M3 9l9-7 9 7v11a2 2 0 0 1-2 2H5a2 2 0 0 1-2-2z"></path> <polyline points="9 22 9 12 15 12 15 22"></polyline> </svg> Dashboard <span class="sr-only">(current)</span> </a> </li> <!--引入侧边栏;传入参数--> <div th:replace="commons/bar::#sidebar(activeUri='emps')"></div>
CRUD-员工添加
添加页面
<form> <div class="form-group"> <label>LastName</label> <input type="text" class="form-control" placeholder="zhangsan"> </div> <div class="form-group"> <label>Email</label> <input type="email" class="form-control" placeholder="zhangsan@atguigu.com"> </div> <div class="form-group"> <label>Gender</label><br/> <div class="form-check form-check-inline"> <input class="form-check-input" type="radio" name="gender" value="1"> <label class="form-check-label">男</label> </div> <div class="form-check form-check-inline"> <input class="form-check-input" type="radio" name="gender" value="0"> <label class="form-check-label">女</label> </div> </div> <div class="form-group"> <label>department</label> <select class="form-control"> <option>1</option> <option>2</option> <option>3</option> <option>4</option> <option>5</option> </select> </div> <div class="form-group"> <label>Birth</label> <input type="text" class="form-control" placeholder="zhangsan"> </div> <button type="submit" class="btn btn-primary">添加</button> </form>
提交的数据格式不对：生日：日期；
2017-12-12；2017/12/12；2017.12.12；
日期的格式化；SpringMVC将页面提交的值需要转换为指定的类型;
2017-12-12---Date； 类型转换，格式化;
默认日期是按照/的方式；
7）、CRUD-员工修改
修改添加二合一表单
<!--需要区分是员工修改还是添加；--> <form th:action="@{/emp}" method="post"> <!--发送put请求修改员工数据--> <!-- 1、SpringMVC中配置HiddenHttpMethodFilter;（SpringBoot自动配置好的）
2、页面创建一个post表单
3、创建一个input项，name="_method";值就是我们指定的请求方式 --> <input type="hidden" name="_method" value="put" th:if="${emp!=null}"/> <input type="hidden" name="id" th:if="${emp!=null}" th:value="${emp.id}"> <div class="form-group"> <label>LastName</label> <input name="lastName" type="text" class="form-control" placeholder="zhangsan" th:value="${emp!=null}?${emp.lastName}"> </div> <div class="form-group"> <label>Email</label> <input name="email" type="email" class="form-control" placeholder="zhangsan@atguigu.com" th:value="${emp!=null}?${emp.email}"> </div> <div class="form-group"> <label>Gender</label><br/> <div class="form-check form-check-inline"> <input class="form-check-input" type="radio" name="gender" value="1" th:checked="${emp!=null}?${emp.gender==1}"> <label class="form-check-label">男</label> </div> <div class="form-check form-check-inline"> <input class="form-check-input" type="radio" name="gender" value="0" th:checked="${emp!=null}?${emp.gender==0}"> <label class="form-check-label">女</label> </div> </div> <div class="form-group"> <label>department</label> <!--提交的是部门的id--> <select class="form-control" name="department.id"> <option th:selected="${emp!=null}?${dept.id == emp.department.id}" th:value="${dept.id}" th:each="dept:${depts}" th:text="${dept.departmentName}">1</option> </select> </div> <div class="form-group"> <label>Birth</label> <input name="birth" type="text" class="form-control" placeholder="zhangsan" th:value="${emp!=null}?${#dates.format(emp.birth, 'yyyy-MM-dd HH:mm')}"> </div> <button type="submit" class="btn btn-primary" th:text="${emp!=null}?'修改':'添加'">添加</button> </form>
CRUD-员工删除
<tr th:each="emp:${emps}"> <td th:text="${emp.id}"></td> <td>[[${emp.lastName}]]</td> <td th:text="${emp.email}"></td> <td th:text="${emp.gender}==0?'女':'男'"></td> <td th:text="${emp.department.departmentName}"></td> <td th:text="${#dates.format(emp.birth, 'yyyy-MM-dd HH:mm')}"></td> <td> <a class="btn btn-sm btn-primary" th:href="@{/emp/}+${emp.id}">编辑</a> <button th:attr="del_uri=@{/emp/}+${emp.id}" class="btn btn-sm btn-danger deleteBtn">删除</button> </td> </tr> <script> $(".deleteBtn").click(function(){ //删除当前员工的 $("#deleteEmpForm").attr("action",$(this).attr("del_uri")).submit(); return false;
}); </script>
