jqGrid JSON数据无法显示在表上

Question

I want to show a JSON data at my table as like here: example

I used that CSS imports:

<link rel="stylesheet" href="/css/ui.jqgrid.css"/>
<link rel="stylesheet" href="/css/ui.multiselect.css"/>
<link rel="stylesheet" href="/css/jquery-ui-1.8.1.custom.css"/>

That JS imports:

<script type=text/javascript src="/js/jquery.js"></script>
<script type=text/javascript src="/js/jquery_ui_1.8.1.js"></script>
<script type=text/javascript src="/js/jquery.layout.js"></script>
<script type=text/javascript src="/js/grid.locale-en.js"></script>
<script type="text/javascript">
    $.jgrid.no_legacy_api = true;
    $.jgrid.useJSON = true;
</script>
<script type="text/javascript" src="/js/ui.multiselect.js"></script>
<script type=text/javascript src="/js/jgrid_4.1.js"></script>
<script type="text/javascript" src="/js/jquery.tablednd.js"></script>
<script type="text/javascript" src="/js/jquery.contextmenu.js"></script>

(Some files has different name but they are OK)

I am getting a JSON data from an URL and when I check it it comes correctly at Firebug. That's my HTML data:

<table id="confTable"></table>
<div id="pconfTable"></div>

That's my script to populate data:

jQuery("#confTable").jqGrid({ ajaxGridOptions : {type:"GET"}, serializeGridData : function(postdata) {
            postdata.page = 1;
            return postdata;
        }, url:'/ui/webapp/conf', datatype: 'json', colNames:['Value','Type', 'Target Module', 'Configuration Group', 'Name', 'Description', 'Identity', 'Version', 'System Id', 'Active'],
            colModel:[
                {name:'value',index:'value', width:55},
                {name:'type',index:'type', width:55},
                {name:'targetModule',index:'targetModule', width:150},
                {name:'configurationGroup',index:'configurationGroup', width:180},
                {name:'name',index:'name asc', width:90},
                {name:'description',index:'description', width:90},
                {name:'identity',index:'identity', width:90},
                {name:'version',index:'version', width:90},
                {name:'systemId',index:'systemId', width:100},
                {name:'active',index:'active', width:100}
            ], rowNum:10, width:980, rowList:[10,20,30], pager: '#pconfTable', sortname: 'name', viewrecords: true, sortorder: "desc", caption:"Configuration Information" });
        jQuery("#pconfTable").jqGrid('navGrid', '#pconfTable', {edit:false,add:false,del:false});

That's JSON data that I get:

[{
        "value":"10",
        "type":"Tip 1",
        "targetModule":"Target 1",
        "configurationGroup":null,
        "name":"Configuration Deneme 1",
        "description":null,
        "identity":"Configuration Deneme 1",
        "version":0,
        "systemId":0,
        "active":true
    },
    {
        "value":"50",
        "type":"Tip 2",
        "targetModule":"Target 2",
        "configurationGroup":null,
        "name":"Configuration Deneme 2",
        "description":null,
        "identity":"Configuration Deneme 2",
        "version":0,
        "systemId":0,
        "active":true
    },
    {
        "value":"100",
        "type":"Tip 3",
        "targetModule":"Target 3",
        "configurationGroup":null,
        "name":"Configuration Deneme 3",
        "description":null,
        "identity":"Configuration Deneme 3",
        "version":0,
        "systemId":0,
        "active":true
    }
]

I have formatted indentation to be read easiliy.

However I don't get any error from Firebug and don't have any can't imported files I still have an empty table.

Any ideas?

PS: Is there anything wrong with my JSON data, should I send a data starts as like => total: xxx, page: yyy, records: zzz, rows: or not a must?

Answer 1

To see the grid filled you should use the following jsonReader as additional jqGrid parameter

jsonReader: {
    repeatitems: false,
    id: "value",
    root: function (obj) { return obj; },
    page: function (obj) { return 1; },
    total: function (obj) { return 1; },
    records: function (obj) { return obj.length; }
}

I suppose, that the values from the 'value' column are unique, so I used id: "value" in the jsonReader above.

By the way the ajaxGridOptions : {type:"GET"} do nothing. The default mtype: 'GET' do the same. In the call of navGrid method you should use jQuery("#confTable") instead of jQuery("#pconfTable") .

After the described changed you will have the following demo . In the demo I added height: 'auto' to have less empty space in the grid.
