我需要HTML5的代码帮助。我有web服务运行数据库并返回JSON数据。但是，当谈到HTML5客户端部分时，如何使用它以及如何显示对我来说是一个问题。
WebMethod是'GetItemData'，返回类型是JSON数据的String。数据库表包括：ItemID，ItemName，ItemPrice和ItemOnHand列。
我正在成功发布我的Web服务。
请帮我解决这个编码问题。我随附了这封邮件，附上HTML5客户端代码。从here下载脚本和样式。 JqxGrid是DataGrid控件，它显示从JSON到Grid的整个数据。

试试这个
$.ajax({
cache: false,
type: "GET",
async: false,
data: {},
url: "1231212312312312.svc/webBinding/Result?metaTag=" + meta,
contentType: "application/json; charset=utf-8",
crossDomain: true,
success: function(){},
error: function(){}
});
