jqgrid won't load json data

问题

I am new to jqgrid and am trying to use json to load the data. I have tried to use the jqgrid demos as a base and then build from there. The json data looks good, but I can't get anything loaded into the grid. Any ideas? I was hoping the use of loaderror or loadcomplete would at least give me insight, but I am not able to retrieve any message why the grid won't load.

json data:

{
    "page": "1",
    "total": 1,
    "records": "12",
    "rows": [
        [
            "67",
            "3 - Sandbox: Appointment Set"
        ],
        [
            "68",
            "1 - Sandbox: Email requested"
        ],
        [
            "69",
            "2 - Sandbox: Questions not answered"
        ],
        [
            "74",
            "1 - TenPointSix: Email requested for more information"
        ],
        [
            "75",
            "2 - TenPointSix: Registered for webinar2"
        ],
        [
            "76",
            "3 - TenPointSix: Webinar registration confirmed"
        ],
        [
            "93",
            "5-Test Entry"
        ],
        [
            "94",
            "test3"
        ],
        [
            "95",
            "test2"
        ],
        [
            "97",
            "Jeff"
        ],
        [
            "103",
            "sortorder"
        ],
        [
            "106",
            "reload"
        ]
    ]
}

My grid code:

<table id="jsonmap"></table>
<div id="pjmap"></div>       

    <script language="JavaScript" type="text/javascript">


 jQuery("#jsonmap").jqGrid({        
    url:'sampleLoad.php?client=<?=$clientId5?>',
    datatype: "json",
        ajaxGridOptions: { contentType: 'application/json; charset=utf-8' },
    colNames:['Inv No','Name'],
    colModel:[
        {name:'id',index:'id', width:55},
        {name:'name',index:'name', width:100}

    ],
    rowNum:15,
    rowList:[15,30,45],
    pager: '#pjmap',
    sortname: 'id',

    viewrecords: true,
    sortorder: "asc",
    jsonReader: {
        root: "Rows",
        cell: "",
        page: "Page",
        total: "Total",
        records: "Records",
        repeatitems: false,
        id: "0"
    },
    loadComplete: function() {

        alert("Load Complete");
    },
    loadError: function(xhr,st,err) { $("#jsonmapMessage").html("Type: "+st+"; Response: "+ xhr.status + " "+xhr.statusText); },



    caption: "JSON Mapping",
        width: '900',
                height: '300'

});


jQuery("#jsonmap").jqGrid('navGrid','#pjmap',{edit:true,add:false,del:false});

Any help would be appreciated.

Thanks,

Jeff

回答1:

The problem is the wrong jsonReader which you use. For example you use rows in the JSON data, but use root: "Rows". The format of the data corresponds default repeatitems: true property, but you used repeatitems: false and so on.

The correct jsonReader is

jsonReader: {
    cell: "",
    id: "0"
}

Additionally I would recommend you to add gridview: true and use height: 'auto' instead of height: '300' which simplify the setting of height.

The demo shows the modifications.
