jqGrid子网格与“本地”数据

Question

我想让我的子网格与本地数据一起工作。然而，当我点击展开时，我只是得到一个装载框，就像网格试图从某处拉取数据。由于主网格的数据类型为datatype:'local'，因此我假设我不需要subGridUrl。还有什么我应该做的？

没有直接的方法可以用本地数据定义子网格，但使用subGridRowExpanded（Subgrid as Grid）可以相对容易地实现相同的行为。人们需要做的只是从网格的rowid中获取一些内部结构的子网格数据。例如，如果你将有局部栅格地图作为

var myGridData = [ 
     // main grid data 
     {id: "m1", col1: "11", col2: "12"}, 
     {id: "m2", col1: "21", col2: "22"} 
    ], 
    mySubgrids = { 
     m1: [ 
      // data for subgrid for the id=m1 
      {id: "s1a", c1: "aa", c2: "ab", c3: "ac"}, 
      {id: "s1b", c1: "ba", c2: "bb", c3: "bc"}, 
      {id: "s1c", c1: "ca", c2: "cb", c3: "cc"} 
     ], 
     m2: [ 
      // data for subgrid for the id=m2 
      {id: "s2a", c1: "xx", c2: "xy", c3: "xz"} 
     ] 
    }; 

里面的subGridRowExpanded你可以用下面的代码创建子网格：

$("#grid").jqGrid({ 
    datatype: 'local', 
    data: myGridData, 
    colNames: ['Column 1', 'Column 2'], 
    colModel: [ 
     { name: 'col1', width: 200 }, 
     { name: 'col2', width: 200 } 
    ], 
    ... 
    subGrid: true, 
    subGridRowExpanded: function (subgridDivId, rowId) { 
     var subgridTableId = subgridDivId + "_t"; 
     $("#" + subgridDivId).html("<table id='" + subgridTableId + "'></table>"); 
     $("#" + subgridTableId).jqGrid({ 
      datatype: 'local', 
      data: mySubgrids[rowId], 
      colNames: ['Col 1', 'Col 2', 'Col 3'], 
      colModel: [ 
       { name: 'c1', width: 100 }, 
       { name: 'c2', width: 100 }, 
       { name: 'c3', width: 100 } 
      ], 
      ... 
     }); 
    } 
});
