EasyUI的DataGrid绑定Json数据源的示例代码

EasyUI给表格绑定数据是最常用的方法,小编分享一下总结出来的两种绑定表格方法,知识在于积累。

第一种:数据存放在数据集中,每一行对应多个值,利用循环把数据绑定到表格

前台代码:

<table id="dg" class="easyui-datagrid" style="width:100%;height:100%;" title="需要设置表格标题" data-options=" 
        rownumbers:true, 
        singleSelect:true, 
        @*autoRowHeight:false,*@ 
        pagination:true 
        @*pageSize:10*@"> 
      <thead> 
        <tr> 
          <th field="colum1">列1</th> 
          <th field="colum2">列2</th> 
          <th field="colum3">列3</th> 
          <th field="colum4">列4</th> 
          <th field="colum5">列5</th> 
          <th field="colum6">列6</th> 
        </tr> 
      </thead> 
    </table>

JS代码:

(function ($) { 
  function pagerFilter(data) { 
    if ($.isArray(data)) { // is array 
      data = { 
        total: data.length, 
        rows: data 
      } 
    } 
    var target = this; 
    var dg = $(target); 
    var state = dg.data('datagrid'); 
    var opts = dg.datagrid('options'); 
    if (!state.allRows) { 
      state.allRows = (data.rows); 
    } 
    if (!opts.remoteSort && opts.sortName) { 
      var names = opts.sortName.split(','); 
      var orders = opts.sortOrder.split(','); 
      state.allRows.sort(function (r1, r2) { 
        var r = 0; 
        for (var i = 0; i < names.length; i++) { 
          var sn = names[i]; 
          var so = orders[i]; 
          var col = $(target).datagrid('getColumnOption', sn); 
          var sortFunc = col.sorter || function (a, b) { 
            return a == b ? 0 : (a > b ? 1 : -1); 
          }; 
          r = sortFunc(r1[sn], r2[sn]) * (so == 'asc' ? 1 : -1); 
          if (r != 0) { 
            return r; 
          } 
        } 
        return r; 
      }); 
    } 
    var start = (opts.pageNumber - 1) * parseInt(opts.pageSize); 
    var end = start + parseInt(opts.pageSize); 
    data.rows = state.allRows.slice(start, end); 
    return data; 
  } 
 
  var loadDataMethod = $.fn.datagrid.methods.loadData; 
  var deleteRowMethod = $.fn.datagrid.methods.deleteRow; 
  $.extend($.fn.datagrid.methods, { 
    clientPaging: function (jq) { 
      return jq.each(function () { 
        var dg = $(this); 
        var state = dg.data('datagrid'); 
        var opts = state.options; 
        opts.loadFilter = pagerFilter; 
        var onBeforeLoad = opts.onBeforeLoad; 
        opts.onBeforeLoad = function (param) { 
          state.allRows = null; 
          return onBeforeLoad.call(this, param); 
        } 
        var pager = dg.datagrid('getPager'); 
        pager.pagination({ 
          onSelectPage: function (pageNum, pageSize) { 
            opts.pageNumber = pageNum; 
            opts.pageSize = pageSize; 
            pager.pagination('refresh', { 
              pageNumber: pageNum, 
              pageSize: pageSize 
            }); 
            dg.datagrid('loadData', state.allRows); 
          } 
        }); 
        $(this).datagrid('loadData', state.data); 
        if (opts.url) { 
          $(this).datagrid('reload'); 
        } 
      }); 
    }, 
    loadData: function (jq, data) { 
      jq.each(function () { 
        $(this).data('datagrid').allRows = null; 
      }); 
      return loadDataMethod.call($.fn.datagrid.methods, jq, data); 
    }, 
    deleteRow: function (jq, index) { 
      return jq.each(function () { 
        var row = $(this).datagrid('getRows')[index]; 
        deleteRowMethod.call($.fn.datagrid.methods, $(this), index); 
        var state = $(this).data('datagrid'); 
        if (state.options.loadFilter == pagerFilter) { 
          for (var i = 0; i < state.allRows.length; i++) { 
            if (state.allRows[i] == row) { 
              state.allRows.splice(i, 1); 
              break; 
            } 
          } 
          $(this).datagrid('loadData', state.allRows); 
        } 
      }); 
    }, 
    getAllRows: function (jq) { 
      return jq.data('datagrid').allRows; 
    } 
  }) 
})(jQuery);
