jqGrid在加载时卡住了吗?

jqGrid

我将在下面向网格传递一个JSON对象 format

{
    "total":1,
    "page":1,
    "records":10,
    "rows":
        [{
        "i":1,"cell":["foo","bar"]},
           {"i":2,"cell":["foo1","barr"]},
           {"i":3,"cell":["foo2","barrr"]}]
}

jQuery("#searchResults").jqGrid({
                    url: '/Customer/SearchResults/',
                    datatype: 'json',
                    mtype: 'GET',
                    colNames: ['Surname', 'Forename'],
                    colModel: [
                      { name: 'Surname', index: 'Surname', width: 200, align: 'left' },
                      { name: 'Forename', index: 'Forename', width: 200, align: 'left'}],
                    pager: jQuery('#pager'),
                    rowNum: 10,
                    rowList: [5, 10, 20, 50],
                    sortname: 'Id',
                    sortorder: "desc",
                    viewrecords: true,
                    imgpath: '/scripts/themes/coffee/images',
                    caption: 'My first grid'
                });

它击中了我的动作,但网格在加载时卡住了,你知道我做错了什么吗??
