我创建了一个Web服务。我想使用Ajax jQuery访问此Web服务。我可以访问同一个域。但我想从另一个域访问此Web服务。

Does anyone have an idea how to create a cross domain web service in asp.net? Any setting in web.config file so that I access it from another domain?

有谁知道如何在asp.net中创建跨域Web服务? web.config文件中的任何设置,以便我从另一个域访问它?

[WebService(Namespace = "http://tempuri.org/")]

    [WebMethod]
    public string SetName(string name) {
        return "hello my dear friend " + name;

    cache: false,
    dataType: "jsonp",
    success: onSuccess
});

the use of jQuery's jsonp datatype is indeed a good choice as it will make cross-domain scripting possible... but since this is json-with-padding you must make sure your webservice returns json..

使用jQuery的jsonp数据类型确实是一个不错的选择,因为它可以使跨域脚本编写成为可能......但由于这是json-with-padding,你必须确保你的webservice返回json ..
