JQuery请求无法在Chrome和Firefox中使用。适用于IE

标签: javascript jquery ajax

我在本地托管了一个WCF服务,并且还在本地托管了一个网站。我为成功处理的JSON数据做了一个GET ajax请求。我有一个问题,在Chrome和Firefox中,它会进入Ajax请求的错误块。

 <!--jQuery dependencies-->
    <link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.9.1/themes/base/jquery-ui.css" />
    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script> 
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.9.1/jquery-ui.min.js"></script>
<script type="text/javascript" src="../../Library/JS/pqgrid.min.js"></script>
<script type="text/javascript">
    var jqNew = $.noConflict(true);
</script>

由于网站的复杂性,我使用的是两个不同版本的JQuery。较新版本的别名为jqNew。

jqNew(document).ready(function () {
        $($.ajax({
            url: "http://wks52025:82/WcfDataService.svc/GetNotesFromView()?$format=json",
            type: "GET",
            datatype: "json",
            async: false,
            success: function (data, textStatus) {
                alert(textStatus);
                $.each(data.d, function (i, item) {
                    alert(i);
                    DataArray[i] = [];
                    DataArray[i][0] = item.NotesID;
                    DataArray[i][1] = item.NotesTitle;
                    DataArray[i][2] = item.NotesText;
                    DataArray[i][3] = item.ProfileName;
                    DataArray[i][4] = item.IsShared;
                    DataArray[i][5] = item.NameOfUser;
                });
            },
            error: function (data, textStatus) {
                alert(textStatus);
            }
        })).then(buildGrid(DataArray));

这是我的要求。它是同步的,因为我在构建网格之前需要数据。这是一个GET请求,因为我想要的只是检索数据。我没有做跨域请求,因为一切都在本地发生,至少我认为它是本地的,因为网站和服务是localhost。

这是我的WCF服务。配置位于代码块的顶部。

任何人都知道为什么这在firefox和chrome中不起作用?
