jquery – 来自USGS geojson数据的jqGrid

我正在尝试阅读并在jqGrid中发布从USGS存储库中提取的一组地震GeoJSON数据.
请求被接受,但在可能满足标头元数据时显示“Uncaught SyntaxError：Unexpected token”.

$(function () {
    'use Strict';
    $.extend($.jgrid.search,{multipleSearch: true,multipleGroup: true,overlay: 0});
    $('#grid').jqGrid({
        url: 'http://earthquake.usgs.gov/earthquakes/Feed/geojson/2.5/week?callBACk=?',datatype: 'json',colmodel: [
            {name: 'mag',label: 'MAGNITUDO',width: 150,jsonmap: 'properties.mag',sorttype: 'number',formatter: 'number',formatoptions: {decimalPlaces: 2}},{name: 'place',label: 'LOCALITA',jsonmap: 'properties.place'},{name: 'url',label: 'URL',jsonmap: 'propertieS.Url'}
        ],toppager: true,gridview: true,rowList: [10,20,50,10000],rowNum: 10,jsonReader: {
            root: 'features',repeatitems: false
        },loadonce: true,ignoreCase: true,height: 'auto'
    }).jqGrid('navGrid','#grid_toppager',{add: false,edit: false,del: falsE})
      .jqGrid('filterToolbar',{StringResult: true,defaultSearch: 'cn',searchOnEnter: falsE});
    $("#grid_toppager option[value=10000]").text('All');
});

你有什么解决方案吗？
提前致谢.
