Question

我的jqrid有这个代码。但是数据没有显示在网格中。生成网格，但网格中没有显示数据。我也应用了错误控制，但这没有给我任何错误。代码如下：

$(document).ready(function () {
'use strict';
var expHeadVal = "12345:Party;12346:Miscellaneous;12347:Conveyance;12348:Staff Welfare";
var webForm = document.forms[0];
var i = 0;
var mydata = "";
var jsonData = { 
    "records": "4",
    "userData":{

    },
    "rows":[
    {"id":"1", "sdate":"2013-03-22","expHead":"Party","expAmt":"1000","expReason":"Yes","expRemark":"FedEx"},
    {"id":"2", "sdate":"2013-03-21","expHead":"Conveyance","expAmt":"200","expReason":"Yes","expRemark":"FedEx"},
    {"id":"3", "sdate":"2013-03-20","expHead":"Conveyance","expAmt":"165","expReason":"Yes","expRemark":"FedEx"},
    {"id":"4", "sdate":"2013-03-11","expHead":"Staff Welfare","expAmt":"1653","expReason":"Yes","expRemark":"FeEx"}
    ]
}
//  alert (jsonData.rows[3].id);
var $grid = $("#View1"),
    initDateWithButton = function (elem) {
        if (/^\d+%$/.test(elem.style.width)) {
                    // remove % from the searching toolbar
            elem.style.width = '';
        }
                // to be able to use 'showOn' option of datepicker in advance searching dialog
                // or in the editing we have to use setTimeout
        setTimeout(function () {
            $(elem).datepicker({
                dateFormat: 'dd-M-yy',
                showOn: 'button',

        }, 100);
    },
    numberTemplate = {

            attr: {size: 11}   // for the searching toolbar
        }
    },
    lastSel;

$grid.jqGrid({

            $(this).jqGrid('restoreRow', lastSel);

        var p = this.p, $this = $(this);
           // if the row are still non-selected

$grid.jqGrid('gridResize', { minWidth: 450, minHeight: 150 });
$grid.jqGrid('navGrid', '#pView1', {refreshstate: 'current', edit: false, add: false, del: false});
$grid.jqGrid('inlineNav',"#pView1");
});

有谁可以告诉我这里缺少什么？

提前感谢您的帮助。

您应该将data: jsonData更改为data: jsonData.rows，因为您使用datatype: "local"。

顺便提一句jsonReader选项不会用于datatype: "local"。 jsonData.rows中的数据格式已经与datatype: "local"的输入数据的默认格式相对应。如果您需要使用datatype: "local"填充其他数据格式的jqGrid，则应使用localReader选项而不是jsonReader（请参阅the documentation）。
