这几天在研究JQuery和WebService,被泛型返回类型搞死了。查了很多资料做实验终于搞定了。网上很多垃圾文章的作者都不亲手实验就到处拼凑把东西发上来,太不负责了。下面我发的是100%可用的,经过亲手实验的代码。 首先在WebService上要注意一点,一定记得把[System.Web.Script.Services.ScriptService]这行取消注释,这样脚本才可以调用到WebService。如图: 我用来测试的是我网站的友情链接列表,其WebService方法如下: [WebMethod] public List GetFriendLinks() { return new EdiBlog.Core.FriendLink().GetModelList(); } 经过测试,在浏览器中用GET访问是会爆掉的,所以我们用POST方法去调用。在默认的IIS和ASP. …
