jqGrid不显示单行

【中文标题】jqGrid不显示单行

【英文标题】：jqGrid not displaying a single row

【问题描述】：

我们的 jqGrid 运行良好 - 如果我们返回 > 1 行，一切正常。

但是.. 如果我们只返回一行，网格不会显示任何数据，并且导航栏会显示 NaN 的 1。很奇怪 - 有什么想法吗？？

这是为单行返回的 JSON：

"records":"1","page":"1","total":"1","rows":"cell":["ECS","D","201009","","0","ABCD","0","0","","201009"],"id":"692334"

两行：

"records":"2","page":"1","total":"1","rows":["cell":["BJL","F","201008","","0","ABCD","0","0","","201008"],"id":"724588","cell":["BJL","F","201008","","0","ABCD","15","10","","201008"],"id":"728676"]

要加载/重新加载我们拥有的网格：

function reloadGrid(u, grid) 
  if (u!= null) 
      grid.setGridParam(url:u);
  

  grid.setGridParam(page:'1', datatype:'json', loadonce:'true'); 
  grid.trigger("reloadGrid");

还有网格本身：

$("#list").jqGrid(
url:'NoData.json',
datatype: 'json',
mtype: 'GET',
colNames:['Product', 'Type','Expiry', 'Put Call', 'Strike', 'Account','Long','Short', 'Open Qty', 'LTD', 'Operations'],
colModel :[
  name:'product', index:'product', width:75,
  name:'type', index:'type', width:50, align:'right',
  name:'expiry', index:'expiry', width:60, align:'right',
  name:'putCall', index:'putCall', width:65,
  name:'strike', index:'strike', sorttype: 'float', width:70,
  name:'account', index:'account', width:70,
  name:'long', index:'long', sorttype: 'int', width:55, align:'right',
  name:'short', index:'short', sorttype: 'int', width:55, align:'right',
  name: 'openQty', index:'openQty', width:80, align:'center', sortable:false, search:false, formatter:closeoutFormatter,
  name:'LTD', index:'LTD', width:65, align:'right',
  index:'operations', width:105, title:false, search:false, align: 'center', formatter:opsFormatter, sortable:false
],
pager: '#pager',
scrollOffset:0, //No scrollbar
rowNum:15,
width:'100%',
viewrecords: true ,
caption: 'Positions',
height: '360',
hidegrid: false //Don't show the expand/collapse button on the top right
).navGrid("#pager",edit:false,add:false,del:false,
beforeRefresh: function()
    reloadPositionGrid();  //Required so that we go to the server and not reload local data

);

【问题讨论】：

JSON 看起来不错，您能否包含 2 行的 JSON 对象、用于设置 jqGrid 的 JS 或输出的 html。我用单行的 jqGrid 就好了

我也遇到了同样的问题***.com/questions/12702106/…

【参考方案1】：

好的，1 的 JSON 没有将行放在 ARRAY 中，它只是放在 OBJECT 中

1 行

"":"", "rows":"cell":["",""], "id": "111"

2 行

"":"", "rows":["cell":["",""], "id": "111", "cell":["",""], "id": "222"]

第二个 JSON 块包含 [,] 中的行

检查输出 JSON 的服务器端代码。

没问题，jqGrid 已经把我打死了好几次，而且总是很简单;)
