我正在尝试动态创建网格。我的目标是创建一种动态前端来显示一些数据库表。所以我需要动态添加/删除列。我需要动态更改列的数据类型。

我使用 a similar question 中提供的脚本作为答案。

我构建了网格，它显示了我的列。但没有数据加载到网格中。 Firebug 显示请求被触发。返回正确的 json 数据。事实上 grid 也会触发 gridComplete 事件。但没有显示任何数据:-(

有人遇到过这个问题吗？我花了一整天的时间调整 jsonReader 和 colModel 但没有效果

我的示例 html 文件:

<!doctype html>
<html>
<link href="../styles/layout.css" rel="stylesheet" type="text/css" />
<script type="text/javascript"
 src="/struts2-jquery-grid-showcase/struts/js/base/jquery-1.4.2.js"></script>
<script type="text/javascript"
 src="/struts2-jquery-grid-showcase/struts/js/base/jquery-ui.js"></script>
<script type="text/javascript"
 src="/struts2-jquery-grid-showcase/struts/js/plugins/jquery.form.js"></script>
<script type="text/javascript"
 src="/struts2-jquery-grid-showcase/struts/js/plugins/jquery.subscribe.js"></script>
<link rel="stylesheet" href="../themes/showcase/jquery-ui.css"
 type="text/css" />
<script type="text/javascript"
 src="/struts2-jquery-grid-showcase/struts/js/plugins/jquery.jqGrid.js"></script>
<script type="text/javascript"
 src="/struts2-jquery-grid-showcase/struts/js/struts2/jquery.struts2.js"></script>
<script type="text/javascript" src="../js/refData.js"></script>
<script type="text/javascript">
jQuery(document).ready(function () {
 jQuery.struts2_jquery.debug = true;
 jQuery.struts2_jquery.loadAtOnce = true;
   jQuery.scriptPath = "/struts2-jquery-grid-showcase/struts/";
 jQuery.struts2_jquery.minSuffix = "";
 jQuery.ajaxSettings.traditional = true;

 jQuery.ajaxSetup ({
  cache: false
 });
 $.ajax(
      {
         type: "POST",
         url: "/struts2-jquery-grid-showcase/refData-table.action",
         data: "",
         dataType: "json",
         success: function(result)
         {
              colD = result.gridModel;
              colN = result.colNames;
              colM = result.colModel;

              jQuery("#refData").jqGrid({
                  jsonReader : {
                      cell: "",
                      id: "0"
                  },
                  url: 'SomeUrl/Getdata',
                  datatype: 'jsonstring',
                  mtype: 'POST',
                  datastr : colD,
                  colNames:colN,
                  colModel :colM,
                  pager: jQuery('#pager'),
                  rowNum: 5,
                  rowList: [5, 10, 20, 50],
                  viewrecords: true,
                  loadComplete: function(data){alert('loaded');},
                  loadError: function(xhr,status,error){alert('error');}
              })
         },
         error: function(x, e)
         {
              alert(x.readyState + " "+ x.status +" "+ e.msg);   
         }
      });
  setTimeout(function() {$("#refData").jqGrid('setGridParam',{datatype:'json'}); },500);
});
</script>
<h2>Maintain Reference Data</h2>
<table id="refData">
 <tr>
  <td />
 </tr>
</table>
<div id="pager"></div>
</html>

我的 json 数据:

{"JSON":"success","colModel":[{"editable":true,"edittype":"integer","index":"userInfoId","jsonmap":"userInfoId","key":false,"name":"userInfoId","resizable":true,"search":false,"sortable":true,"width":300},{"editable":true,"edittype":"text","index":"UserID","jsonmap":"userID","key":true,"name":"userID","resizable":true,"search":false,"sortable":true,"width":300}],"colNames":["UserInfo ID","User ID"],"gridModel":[{"userID":"SMI","userInfoId":5},{"userID":"ABC","userInfoId":7},{"userID":"PQR","userInfoId":8},{"userID":"FUR","userInfoId":10},{"userID":"COO","userInfoId":13}],"page":1,"records":56,"rows":15,"sidx":null,"sord":"asc","total":0}

最佳答案

在我看来，您忘记将 {} 作为 gridModel 的包含。目前数据看起来像 

{
    "JSON": "success",
    "colModel": [
       ...
    ],
"colNames": [ "UserInfo ID", "User ID" ],
"gridModel": [
        {"userID": "SMI","userInfoId": 5},
        {"userID": "ABC","userInfoId": 7},
        {"userID": "PQR","userInfoId": 8},
        {"userID": "FUR","userInfoId": 10},
        {"userID": "COO","userInfoId": 13}
    ],
    "page": 1,
    "records": 56,
    "rows": 15,
    "sidx": null,
    "sord": "asc",
    "total": 0
}

而不是

{
    "JSON": "success",
    "colModel": [
       ...
    ],
"colNames": [ "UserInfo ID", "User ID" ],
"gridModel": { [
        {"userID": "SMI","userInfoId": 5},
        {"userID": "ABC","userInfoId": 7},
        {"userID": "PQR","userInfoId": 8},
        {"userID": "FUR","userInfoId": 10},
        {"userID": "COO","userInfoId": 13}
    ],
    "page": 1,
    "records": 56,
    "rows": 15,
    "total": 0
  }
}

使用“jsonmap”似乎我也不是真正需要的。
