layui之数据表格--与后台交互获取数据

jsp或html

<table id="userList" lay-filter="userList"></table>

js

//用户列表
var tableIns = table.render({
    elem: '#userList',
    url : 'userAction_findAll.action',
    cellMinWidth : 95,
    page : true,
    height : "full-125",
    limits : [10,15,20,25],
    limit : 10,
    id : "userListTable",
    cols : [[
        {type: "checkbox", fixed:"left", width:50},
        {field: 'userName', title: '用户名', minWidth:100, align:"center"},
        {field: 'userEmail', title: '用户邮箱', minWidth:200, align:'center',templet:function(d){
            return '<a class="layui-blue" href="mailto:'+d.userEmail+'">'+d.userEmail+'</a>';
        }},
        {field: 'userSex', title: '用户性别', align:'center'},
        {field: 'userStatus', title: '用户状态',  align:'center',templet:function(d){
            return  d.userStatus == '0' ? "正常使用":"<span class='layui-red'>限制使用</span>";
        }},
        {field: 'userGrade', title: '用户等级', align:'center'},
        {field: 'userEndTime', title: '最后登录时间', align:'center',minWidth:150},
        {title: '操作', minWidth:175, templet:'#userListBar',fixed:"right",align:"center"}
    ]]
});

UserAction.java

// 接收前端发送来的分页参数
private int page = 1;
public void setPage(int page) {
    this.page = page;
}
public int getPage() {
    return page;
}
private int limit = 2;
public int getLimit() {
    return limit;
}
public void setLimit(int limit) {
    this.limit = limit;
}

public String findAll(){
    List<User> allUser = this.getUserService().findAllUser(this.getPage(), this.getLimit());
    Map<String, Object> result = new HashMap<String, Object>();
    result.put("code", 0);
    result.put("msg", "");
    result.put("count", this.getUserService().findTotalRecord(key));
    JSONArray array = JSONArray.fromObject(allUser);
    result.put("data", array);
    // 将其转换为JSON数据，并压入值栈返回
    ActionContext.getContext().getValueStack().set("jsonData", JSONObject.fromObject(result));
    return "success";
}

struts.xml配置

<!-- 用户配置 -->
<package name="user" namespace="/" extends="common,json-default">
    <action name="userAction_*" class="userAction" method="{1}">
        <result name="success" type="json">
            <param name="root">jsonData</param>
        </result>
    </action>
</package>

返回JSON数据格式，也是layui数据表格要求的格式

{
  "code": 0,
  "msg": "",
  "count": 15,
  "data": [
    {
      "usersId": "1",
      "userName": "user12",
      "userEmail": "[email protected]",
      "userSex": "女",
      "userStatus": "0",
      "userGrade": "倔强青铜",
      "userEndTime": "2018-11-11 15:22:33"
    },{
      "usersId": "2",
      "userName": "asd",
      "userEmail": "[email protected]",
      "userSex": "男",
      "userStatus": "1",
      "userGrade": "秩序白银",
      "userEndTime": "2018-11-11 15:22:33"
    },
    ......
  ]
}

注意：

1.js中table的field需要与返回的数据key相对应，比如field: ‘userName’与“userName”: “asd”
2.layui的数据表格向url发送请求时，会附上page以及limit这两个参数，所以服务端需要接收并以此为条件查找数据
