Layui表格选中指定行的radio单选框并滚动到该行的实现代码

    layui table有多行数据,通过外部输入内容,需要定位到指定行,选中改行,对改行进行操作。

    实现效果:

    HTML代码:

    
    <body>
          <div class="layui-fluid">
             <input type="text" id="txt_id" />
              <table class="layui-hide" id="test" lay-filter="test"></table>
              <script type="text/html" id="toolbarDemo">
                  <div class="layui-btn-container">
                      <button class="layui-btn layui-btn-sm" lay-event="getCheckData">获取选中行数据</button>
                     <button class="layui-btn layui-btn-sm" lay-event="SetChecked">设置选中行</button>
                 </div>
             </script>
      
         </div>
         <script src="lib/jquery-1.9.1.min.js"></script>
         <script src="layui/layui.all.js"></script>
         <script src="lib/AjaxCommon.js"></script>
         <script>
             layui.use('table', function () {
                 var table = layui.table; 19 20 ajaxSend(false, 'http://data.app.local/api/test/hello', '', function (res) { 21 if (res != '') { 22  console.log(res) 23  table.render({ 24 elem: '#test' 25 , height: 'full-50' 26  , limit: Number.MAX_VALUE 27  , data: res.data 28 , toolbar: '#toolbarDemo' 29  , cols: [[ 30 { type: 'radio' } 31 , { field: 'Id', width: '50%', title: 'ID', sort: true } 32 , { field: 'Name', width: '50%', title: 'Name', sort: true } 33  ]] 34 , page: false 35  }); 36  } 37 },'get'); 38 39 //头工具栏事件 40 table.on('toolbar(test)', function (obj) { 41 var checkStatus = table.checkStatus(obj.config.id); //获取选中行状态 42 switch (obj.event) { 43 case 'getCheckData'://获取选中行数据 44 var data = checkStatus.data; 45  layer.alert(JSON.stringify(data)); 46 break; 47 case 'SetChecked'://设置指定行 48 var id = $("#txt_id").val(); 49 var tabledata = table.cache["test"]; //获取现有数据 50  console.log(tabledata) 51 var index = 0; 52 for (var i = 0; i < tabledata.length; i++) { 53 if (tabledata[i].Id == id) { 54 tabledata[i].LAY_CHECKED = true; 55 index = i; 56  } 57 else { 58 tabledata[i].LAY_CHECKED = false; 59  } 60  } 61 table.reload("test", { 62  data: tabledata, 63  }) 64 //滚动到指定行 65 var cellHtml = $(".layui-table-main").find("tr[data-index=" + index + "]"); 66 var cellTop = cellHtml.offset().top; 67 $(".layui-table-main").scrollTop(cellTop - 160); 68 break; 69  }; 70  }); 71  }); 72 </script> 73 </body>

    后台代码:

    
     public class LayUITableEntity
      { 
       public string code
      { 
      get; 
      set; 
      }
      public string msg
      { 
      get; 
      set; 
      } 
       public string count 
       {
       get; 
       set;
       } 
        public object data 
        { 
        get;
        set;
        } 
        }
        public class TestEntity 
        {
       /// <summary>
      /// 这个字段用来标识radio是否选中
      /// </summary>
       public bool LAY_CHECKED 
        { 
        get; set;
        } 
        = false; 
        public string Id
        {
        get;
        set; 
        } 
        public string Name
        { 
        get; set;
        } 
        }
        [Route("/api/test")]
        public class TestController : ServiceController
        { 
        [RouteHttpGet("hello")] 
        public FormiumResponse HelloNanUI(FormiumRequest request) 
        { 
         List<TestEntity> teList = new List<TestEntity>(); 
         for (int i = 1; i <= 30; i++) 
        {
       TestEntity te = new TestEntity() 
        { 
         //初次载入,id为3的选中
         LAY_CHECKED = i == 3 ? true : false,
         Id = i.ToString(),
         Name = "name" + i.ToString() 32 
        }; 
        teList.Add(te);
        } 
     LayUITableEntity layUITableEntity = new LayUITableEntity() 
        {
        code = "0",
        count = teList.Count().ToString(),
        msg = "", 
        data = teList
        }; 
        return Json(layUITableEntity); 
        } 
        }
