Javascript 击倒Json获取

我是knockout.js的新手，我有一个问题。我找到了一些密码。我的get函数返回{id:1，name:cardio，image:aslas，header:Kardio，message:message\r\n}，但它不工作。有人能帮我吗？谢谢

         <ul class="folders" data-bind="foreach: folders">
    <li data-bind="text: $data,
               css: { selected: $data == $root.chosenFolderId() },
               click: $root.goToFolder"></li>
</ul>
<div class="mails" data-bind="with: chosenFolderData">
    <p><label>From</label>: <span data-bind="text: name"></span></p>
</div>

<script>
    function WebmailViewModel() {
        // Data
        var self = this;

        self.folders = ['cardio', 'classic', 'mass', 'abs']

        ;
        self.chosenFolderId = ko.observable();
        self.chosenFolderData = ko.observable();
        self.chosenMailData = ko.observable();
        // Behaviours
        self.goToFolder = function(folder) {
            self.chosenFolderId(folder);
            self.chosenMailData(null);
            $.get(ajax_url+'Dieticians/video/'+folder,null, self.chosenFolderData);
        };
        self.goToFolder('Inbox');

    };

    ko.applyBindings(new WebmailViewModel());
</script>

这就是你要找的吗

看起来对我有用。在这里检查。如果你想找一些特别的东西，请告诉我们，上面的小提琴看起来因为拼写错误而断裂了。当您单击文件夹按钮时，它从服务器获取json并将其写入span@超级奥运会你所需要做的只是有一个ajax调用，它可以动态地获取你的数据并将数据推送到self.chosenFolderData中；self.chosenFolderData{'name'：folder}；>$。getajax_url+'Dieticians/video/'+文件夹，null，self.chosenFolderData；它返回{id:1，name:cardio，image:aslmk\u015fga\u015fgkl，header:Kardio，message:messagetext}。但不要在span中写任何东西@超级解析它是有效的，但当我使用：$.getajax_url+'Dieticians/video/'+folder，null，self.chosenFolderData；它不起作用@Kelvin17$.ajax{url:ajax_url+'Dieticians/video/'+文件夹，数据类型：'json'，success:functiondata{self.chosenFolderDatadata；}；如果你想设置它的值，你必须这样说。chosenFolderData[valueyouwant]在一个你在ajax请求成功后创建的函数中，看：希望这有帮助
