c# - 在 JQuery 中读取返回对象

Question

4 分钟前在 JQuery 中读取返回对象|LINK

我创建了一个返回 GenericList 对象的 wcf 服务。我需要使用 Jquery 在客户端读取该对象，但可以使其正常工作：

下面是我的代码：

svc 方法：

[OperationContract]
    [WebGet(ResponseFormat = WebMessageFormat.Json)]
    public CommentList GetComments()
    {
        Comments oComment1 = new Comments();
        oComment1.Title = "AMaking hay when the sun shines";
        oComment1.Author = "Plan_A";
        oComment1.CommentText = "AI like hay almost as much as I like sun. Just joking";

        Comments oComment2 = new Comments();
        oComment2.Title = "Making hay when the sun shines";
        oComment2.Author = "Plan_B";
        oComment2.CommentText = "I like hay almost as much as I like sun. Just joking";

        CommentList oCommentList = new CommentList();
        oCommentList.Comment.Add(oComment1);
        oCommentList.Comment.Add(oComment2);

        return oCommentList;
    }

客户端的 Jquery 脚本：

$('#CommentsButton').click(function () {
        $.getJSON('http://localhost:55679/RESTService.svc/GetComments?callback=?', function (data) {
                 alert(data);

        });

我得到的响应（通过 Inspect 元素 - Chrome 工具）

jsonp1363710839478({"Comment":[{"Author":"Plan_A","CommentText":"AI like hay almost as much as I like sun. Just joking","Title":"AMaking hay when the sun shines"},{"Author":"Plan_B","CommentText":"I like hay almost as much as I like sun. Just joking","Title":"Making hay when the sun shines"}]});

Answer 1

试试这个：

$.getJSON('http://localhost:55679/RESTService.svc/GetComments?callback=?', function (data) {
    alert(data.Comments[0].Author);
});

Answer 2

这行得通。

$.ajax({
        type : "GET",
        dataType : "jsonp",
        url : 'http://localhost:55679/RESTService.svc/GetComments',
        success: function(data){
            console.log(data.Comment.length);
            for(var i=0; i<data.Comment.length; i++){
                console.log(data.Comment[i].Title);
            }
        }
    });
