我有一个本地托管的 WCF 服务和一个本地托管的网站。我对成功处理的 JSON 数据发出 GET ajax 请求。我有一个问题，在 Chrome 和 Firefox 中它进入了 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，我使用了两个不同版本的 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，因为网站和服务是本地主机。

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？
