新增员工信息
实现图如下：
1 利用Bootstrap搭建大致页面
<!--新增员工Model框--> <div class="modal fade" id="Emp_Add_Modal" tabindex="-1" role="dialog" aria-labelledby="Emp_Add_Modal_label"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> <h4 class="modal-title" id="myModalLabel">新增员工</h4> </div> <div class="modal-body"> <form class="form-horizontal"> <div class="form-group"> <label for="empName" class="col-sm-2 control-label">empName:</label> <div class="col-sm-10"> <input type="text" class="form-control" name="empName" id="empName" placeholder="empName"> </div> </div> <div class="form-group"> <label for="email" class="col-sm-2 control-label">email:</label> <div class="col-sm-10"> <input type="email" class="form-control" name="emamil" id="email" placeholder="email"> </div> </div> <div class="form-group"> <label class="col-sm-2 control-label">gender:</label> <div class="col-sm-offset-2 col-sm-10"> <label class="radio-inline"> <input type="radio" name="gender" id="gender1_input" checked="checked" value="M"> 男 </label> <label class="radio-inline"> <input type="radio" name="gender" id="gender2_input" value="F"> 女 </label> </div> </div> <div class="form-group"> <label class="col-sm-2 control-label">deptName:</label> <div class="col-sm-4"> <select class="form-control" name="dId" id="deptName_select"> </select> </div> </div> </form> </div> <div class="modal-footer"> <button type="button" class="btn btn-default" data-dismiss="modal">关闭</button> <button type="button" class="btn btn-primary">保存</button> </div> </div> </div> </div>
按钮：
<!-- 操作按钮 --> <div class="row"> <div class="col-md-4 col-md-offset-8"> <button class="btn btn-primary" id="emp_add_btn" data-toggle="modal" data-target="#Emp_Add_Modal">新增</button> <button class="btn btn-danger" id="emp_delete_btn">删除</button> </div> </div>
$("#emp_add_btn").click(function () {
$('#Emp_Add_Modal').modal({
backdrop:static,
keyboard:true
});
});
2 查询出部门信息，并显示在Modal框中
后台返回部门信息的JSON串：DepartmentController.java:
package com.wgs.controller; import com.wgs.domain.Department; import com.wgs.domain.Msg; import com.wgs.service.DepartmentService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.ResponseBody; import java.util.List; /** * Created by GenshenWang.nomico on 2017/6/9. */ @Controller public class DepartmentController { @Autowired DepartmentService departmentService; @RequestMapping(value = {"dept/deptList"}, method = {RequestMethod.GET}) @ResponseBody public Msg getAllDepts(){ List<Department> departmentList = departmentService.getAllDepartment(); return Msg.success().add("depts", departmentList); } }
发送AJAX请求获取JSON串，并且将部门信息显示在页面上：
$("#emp_add_btn").click(function () { getDeptName("#deptName_select"); $('#Emp_Add_Modal').modal({ backdrop:static, keyboard:true }); }); function getDeptName(ele) { $(ele).empty(); $.ajax({ url: "${APP_PATH}/dept/deptList", type: "GET", success: function (result) { console.log(result); //将信息显示到下拉列表中 $.each(result.extendInfo.depts,function () { alert(1); var optionEle = $("<option></option>").append(this.deptName).attr("value", this.deptId); optionEle.appendTo(ele); }); } });
