四、Web开发（7）

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>

8）、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>
