尝试加载json时，jqGrid给出异常 [英] jqGrid giving exception when json is attempted to be loaded

问题描述

我的网站中包含以下html:

I have the following html in my site:

<link type="text/css" href="/Styles/ui-lightness/jquery-ui-1.8.2.custom.css" rel="Stylesheet" />
<link type="text/css" href="/Styles/ui.jqgrid.css" rel="Stylesheet" />
<script type="text/javascript" src="/Scripts/jquery-1.4.2.min.js" ></script>
<script type="text/javascript" src="/Scripts/jquery-ui-1.8.2.min.js" ></script>
<script type="text/javascript" src="/Scripts/grid.locale-en.js" ></script>
<script type="text/javascript" src="/Scripts/jquery.jqGrid.min.js" ></script><link type="text/css" rel="Stylesheet" href="Styles/Site.css" />

...

<script type="text/javascript">
    $(document).ready(function () {
        jQuery("#tblScheduledReleases").jqGrid({
            url: '/Release/GetScheduledReleases',
            datatype: "json",
            mtype: 'POST',
            colNames: ['Id', 'Version', 'Name', 'Scheduled Date'],
            colModel: [
                { name: 'id', width: 55 },
                { name: 'version', width: 90 },
                { name: 'name', width: 100 },
                { name: 'date', width: 90 }
                  ],
            autowidth: true,
            sortname: 'date',
            viewrecords: true,
            sortorder: "desc",
            caption: "Scheduled Releases"
        });
    });
</script>

....

<table id="tblScheduledReleases"></table>
<div id="divScheduledPager"></div>

现在，在加载时，网格将显示正确的列，然后显示Loading消息.但是，它永久卡在装载区中.打开chrome控制台会显示以下错误:

Now when this loads the grid shows with the correct columns and then shows the Loading message. However, it is perpetually stuck in the loading section. Opening up the chrome console shows the following error:

Uncaught TypeError: Cannot read property '0' of undefined in jquery.jqGrid.min.js:14

这是jqGrid请求的由我的Web服务器返回的Json:

Here is the Json being returned by my webserver requested by the jqGrid:

{
  "page":"1",
  "total":"1",
  "records":6,
  "rows":[
    {"id":"37","version":"4.14.9.1","name":"4.14 Patch 8","date":"2010-07-08"},
    {"id":"39","version":"4.15.4.1","name":"4.15 Patch 3","date":"2010-07-08"},
    {"id":"36","version":"4.13.11.1","name":"4.13 Patch 11","date":"2010-07-15"},
    {"id":"40","version":"4.15.5.1","name":"4.15 Patch 4","date":"2010-07-22"},
    {"id":"38","version":"4.14.10.1","name":"4.14 Patch 9","date":"2010-07-22"},
    {"id":"30","version":"4.16.1.1","name":"4.16 Release","date":"2010-07-30"}
  ]
}

为什么会出现此异常?

推荐答案

您应包括

 jsonReader : { repeatitems: false }

在jqGrid参数中.

in the jqGrid parameters.
