layui 学习笔记一：layui table 查询、新增、编辑、删除

一、table数据的呈现（对应查询）

页面代码：

@{
    ViewBag.Title = "TableGrid";
}
@section styles{
    <link href="~/Scripts/Plugin/layui/css/layui.css" rel="stylesheet" />
}
<h2>TableGrid</h2>
<table id="tblInfo" lay-filter="tblInfo"></table>
@section scripts{
    <script src="~/Scripts/Plugin/layui/layui.all.js"></script>
    <script src="~/Scripts/Test/TableGrid.js"></script>
}

TableGrid.js的代码：

; (function () {
    initQuery();
}());

function initQuery() {
    layui.use(['table'], function () {
        $.post('/Test/TableGridQuery', {}, function (rsp) {
            var table = layui.table,
            tableId = 'tblInfo';
            table.render({
                id: tableId
                , elem: '#' + tableId
                , data: rsp.data
                , cellMinWidth: 80 //全局定义常规单元格的最小宽度，layui 2.2.1 新增
                , cols: [[
                  { field: 'P_NO',  100, title: '页面编号' }
                  , { field: 'P_NAME',  100, title: '页面名称' }
                  , { field: 'P_ROLE',  100, title: '页面角色' }
                  , { field: 'P_DESC', title: '页面说明' }
                  , { field: 'P_URL',  280, title: '页面URL' }
                  , {
                      fixed: 'right',  120, align: 'center', templet: function () {
                          return ' <a class="layui-btn layui-btn-xs" lay-event="edit">编辑</a>
                                   <a class="layui-btn layui-btn-danger layui-btn-xs" lay-event="del">删除</a>';
                      }
                  }
                ]]
            });

            //监听数据操作(其中tableID就是页面中的lay-filter)
            table.on('tool(' + tableId + ')', function (obj) {
                var data = obj.data;
                if (obj.event === 'del') {
                    layer.confirm('真的删除行么', function (index) {
                        layer.msg('删除成功');
                        obj.del();
                        layer.close(index);
                    });
                } else if (obj.event === 'edit') {
                    showEdit(data);
                }
            });
        }, 'json');
    });
}

后台代码 ，对应的是：'/Test/TableGridQuery'

[HttpPost]
public JsonResult TableGridQuery()
{
      ResultClass rc = new ResultClass();
      List<ResultClass1> rc1 = new List<ResultClass1>();
      for (int i = 1; i < 11; i++)
      {
            rc1.Add(new ResultClass1()
            {
                P_NO = i.ToString(),
                P_NAME = "页面名称" + i.ToString(),
                P_ROLE = "页面角色" + i.ToString(),
                P_DESC = "页面描述" + i.ToString(),
                P_URL = "页面URL" + i.ToString()
            });
       }
       rc.data = rc1;
       rc.code = 0;
       rc.count = rc1.Count;
       return Json(rc);
}

页面呈现效果：

二、新增一条新的记录，并呈现到table中

给新增按钮添加事件：

function initShowAdd() {
    $('#btnShowAdd').click(function () {
        var addHtml = '<form id="form1" class="layui-form" method="post" action="/Test/TableGridInsert" style="460px; margin-top: 20px;">
                           <div class="layui-form-item">
                             <label class="layui-form-label">编号</label>
                             <div class="layui-input-block">
                               <input type="text" name="P_NO" lay-verify="title" autocomplete="off" placeholder="请输入编号" class="layui-input">
                             </div>
                           </div>
                           <div class="layui-form-item">
                             <label class="layui-form-label">名称</label>
                             <div class="layui-input-block">
                               <input type="text" name="P_NAME" lay-verify="title" autocomplete="off" placeholder="请输入名称" class="layui-input">
                             </div>
                           </div>
                           <div class="layui-form-item">
                             <label class="layui-form-label">角色</label>
                             <div class="layui-input-block">
                               <input type="text" name="P_ROLE" lay-verify="title" autocomplete="off" placeholder="请输入角色" class="layui-input">
                             </div>
                           </div>
                           <div class="layui-form-item">
                             <label class="layui-form-label">描述</label>
                             <div class="layui-input-block">
                               <input type="text" name="P_DESC" lay-verify="title" autocomplete="off" placeholder="请输入描述" class="layui-input">
                             </div>
                           </div>
                           <div class="layui-form-item">
                             <label class="layui-form-label">URL</label>
                             <div class="layui-input-block">
                               <input type="text" name="P_URL" lay-verify="title" autocomplete="off" placeholder="请输入URL" class="layui-input">
                             </div>
                           </div>
                       </form>';

        layer.open({
            type: 1,
            title: '新增',
            content: addHtml,
            area:['500px','420px'],
            btn: ['提交', '取消'],
            yes: function (layIndex) {
                $('#form1').ajaxSubmit({
                    success: function (rsp) {
                        if (rsp && rsp.success === true) {
                            layer.close(layIndex);
                            var oldData = layui.table.cache.tblInfo;//获得当前页面的原始数据
                            oldData.unshift(rsp.data);//在原始数据前添加新添加的数据
                            layui.table.reload('tblInfo', { data: oldData });//把新处理的数据重新加载一下
                            layer.msg('提交成功');                            
                        }
                        else {
                            if (rsp && rsp.message) {
                                layer.alert(rsp.message);
                            }
                            else {
                                layer.alert('提交失败');
                            }
                        }
                    }
                });
            }
        });
    });
}

三、编辑其中一条记录，并同时更新到table中

新增一个编辑字段：

{
    fixed: 'right',  120, align: 'center', templet: function () {
        return ' <a class="layui-btn layui-btn-xs" lay-event="edit">编辑</a>                              ';
    }
}

监听编辑按钮点击事件：

table.on('tool(' + tableId + ')', function (obj) {
    var data = obj.data;
    if (obj.event === 'del') {
        //删除方法 
    } else if (obj.event === 'edit') {//监听删除
        showEdit(data); //显示编辑对话框
    }
});

showEdit方法内容如下：

function showEdit(data) {
    var editHtml = '<form id="form1" class="layui-form" method="post" action="/Test/TableGridUpdate" style="460px; margin-top: 20px;">
                           <div class="layui-form-item">
                             <label class="layui-form-label">编号</label>
                             <div class="layui-input-block">
                               <input type="text" name="P_NO" lay-verify="title" value="' + data.P_NO + '" autocomplete="off" placeholder="请输入编号" class="layui-input">
                             </div>
                           </div>
                           <div class="layui-form-item">
                             <label class="layui-form-label">名称</label>
                             <div class="layui-input-block">
                               <input type="text" name="P_NAME" value="' + data.P_NAME + '" lay-verify="title" autocomplete="off" placeholder="请输入名称" class="layui-input">
                             </div>
                           </div>
                           <div class="layui-form-item">
                             <label class="layui-form-label">角色</label>
                             <div class="layui-input-block">
                               <input type="text" name="P_ROLE" value="' + data.P_ROLE + '" lay-verify="title" autocomplete="off" placeholder="请输入角色" class="layui-input">
                             </div>
                           </div>
                           <div class="layui-form-item">
                             <label class="layui-form-label">描述</label>
                             <div class="layui-input-block">
                               <input type="text" name="P_DESC" value="' + data.P_DESC + '" lay-verify="title" autocomplete="off" placeholder="请输入描述" class="layui-input">
                             </div>
                           </div>
                           <div class="layui-form-item">
                             <label class="layui-form-label">URL</label>
                             <div class="layui-input-block">
                               <input type="text" name="P_URL" value="' + data.P_URL + '" lay-verify="title" autocomplete="off" placeholder="请输入URL" class="layui-input">
                             </div>
                           </div>
                       </form>';

    layer.open({
        type: 1,
        title: '编辑',
        content: editHtml,
        area: ['500px', '420px'],
        btn: ['提交', '取消'],
        yes: function (layIndex) {
            $('#form1').ajaxSubmit({
                success: function (rsp) {
                    if (rsp && rsp.success === true) {
                        layer.close(layIndex);
                        var oldData = layui.table.cache.tblInfo;
                        var len = oldData.length;
                        //循环数据，找到更新的数据行，直接更新
                        for (var i = 0; i < len; i++) {
                            if (oldData[i].P_NO == rsp.data.P_NO) {
                                oldData[i] = rsp.data;
                                break;
                            }
                        }
                        //重新加一下数据
                        layui.table.reload('tblInfo', { data: oldData });
                        layer.msg('提交成功');
                    }
                    else {
                        if (rsp && rsp.message) {
                            layer.alert(rsp.message);
                        }
                        else {
                            layer.alert('提交失败');
                        }
                    }
                }
            });
        }
    });
}

四、删除其中一条记录

新增一个删除字段：

 {
      fixed: 'right',  120, align: 'center', templet: function () {
           return '  <a class="layui-btn layui-btn-danger layui-btn-xs" lay-event="del">删除</a>';
      }
 }

监听删除按钮的点击事件

table.on('tool(' + tableId + ')', function (obj) {
    var data = obj.data;
    if (obj.event === 'del') {//监听删除
        layer.confirm('真的删除行么', function (index) {
            $.post('/Test/TableGridDelete', { id: data.P_NO }, function (rsp) {
                if (rsp && rsp.success === true) {
                    layer.msg('删除成功');
                    obj.del();
                    layer.close(index);
                } else {
                    if (rsp && rsp.message) {
                        layer.alert(rsp.message);
                    }
                    else {
                        layer.alert('删除失败');
                    }
                }
            }, 'json');
        });
    } else if (obj.event === 'edit') {
        showEdit(data);
    }
});
