jqgrid:无法显示json数据 [英] jqgrid: can't display json data

问题描述

我正在尝试在jqgrid中显示json数据，但没有任何行.

I'm trying to display json data in a jqgrid and I don't get any row.

这是我的网格:

$('#jqList').jqGrid({
        url: '/my/url',
    datatype: 'json',
    colNames:['field1', 'field2'],
    colModel:[
        {name:'field1',index:'field1', width:200},
        {name:'field2',index:'field2', width:300}
    ],
    pager: '#jqPager',
        rowNum: 20,
        rowList: [10, 20, 30, 50],
        height: '100%',
        viewrecords: true,
        jsonReader: {
            repeatitems: false,
            root: function (obj) { return obj; },
            page: function (obj) { return 1; },
            total: function (obj) { return 1; },
            records: function (obj) { return obj.length; },
            id: 'id'
        }
});

我可以在浏览器中访问我的网址，它显示如下内容:

I can access my url in my browser and it displays something like this :

    {"rows": [
        {"id": "3", "field1": "blabla", "field2": "blabla"},
        {"id": "10", "field1": "blabla", "field2": "blabla"},
        {"id": "4", "field1": "blabla", "field2": "blabla"},
        {"id": "8", "field1": "blabla", "field2": "blabla"}
    ]
}

但是当我显示网格时，我没有任何数据. 如果我检查控制台，则我的网址上出现500错误(在网址中添加了一些参数)

But when I display my grid, I don't have any data as I said. If I check the console, I have a 500 error on my url (with some params added to the url)

希望我能提供足够的信息.

I hope I gave enough informations.

修改 Firebug控制台说:

edit firebug console says :

"NetworkError: 500 Internal Server Error - http://localhost/path/to/my/url?_search=false&nd=1373439192511&rows=20&page=1&sidx=&sord=asc"

我在apache服务器上使用PHP

I'm using PHP on apache server

php代码:

header('Content-type: application/json');
foreach ($cars as $k => $v) {
    $tab['rows'][$k] = $v['Car'];
}
echo json_encode($tab);

谢谢

推荐答案

尽管我给了url : path/to/my/url，但jqGrid似乎在等待这样的URL:path/to/my/json/url 在开发服务器上...并且url : path/to/my/url在beta服务器上工作正常...

It seems that jqGrid was waiting a url like that : path/to/my/json/url despite I gave url : path/to/my/url on the development server... and url : path/to/my/url works fine on the beta server...

我真的不明白为什么，如果网址错误"，为什么错误不是404?

I don't really understand why, if the url was "wrong" why the error wasn't 404 ?

无论如何现在都可以正常工作...

Anyway it's working fine now...
