通过Ajax方式绑定select选项数据

<select name="deptId" lay-filter="" lay-search id="deptIdSearch">
 <option value="-1">请选择部门</option>
</select>

Ajax部分

<script type="text/javascript">
  $.ajax({
      type : "post",
      url : "${ctx}/erpsalary/deptAll", 
      success : function(res, status) {
       if(res.code==200)
          $.each(res.data, function(index, item) {
              $("#deptIdSearch").append(  //此处向select中循环绑定数据
          "<option value="+item.id+">" + item.deptName+ "</option>");
          });
    
        },
  });
</script>

Resul数据结构

@RequestMapping("/deptAll")
@ResponseBody
public Result getDept() {
 List<PtDept> queryAll = ptDeptService.queryAll();
 return new Result(200,"ok",queryAll);
}
