我在使用 foreach 显示数据的 Web 应用程序上使用敲除(包括所有需要的库)

我收到以下错误:

Error: Unable to parse bindings. Message: ReferenceError: d is not defined; Bindings value: foreach: d
[Break On This Error]   

...+c+" } ";return new Function("sc",c)},kb:function(a,b){if(b.compareDocumentPosit...

我的 JSON:

{"d":[{"__type":"listingItem:#applicationModel","award_text":"","channel_id":5,"constructed_short_descriptionen":"","constructed_short_descriptiongr":"","constructed_titleen":"","constructed_titlegr":"","country_id"...

我的代码:

var Listing_ViewModel = {};

    var data = $.getJSON("listings.svc/Listing_Get_Items?",
                {
                    startdate: "2012-09-21 00:00:00",
                    stopdate: "2012-09-22 00:00:00",
                    channel_id: "5"
                }, function (data) {
                    // Now use this data to update your view models, 
                    // and Knockout will update your UI automatically 
                    //var parsed = JSON.parse(data);
                    alert(data.d[0].duration);
                    Listing_ViewModel = ko.mapping.fromJSON(data);
                    //alert(ko.mapping.toJS(Listing_ViewModel));
                    ko.applyBindings(Listing_ViewModel);
                    //        ko.applyBindings({
                    //          
                    //        });
                })

HTML 代码:

<!-- ko foreach: d -->
    <li class="item item-even" id="id_1" title="1">
    </li>
<!-- /ko -->

任何想法我做错了什么?对不起,我完全是绿色的!

问题很可能是fromJSON您真正的意思是在使用fromJS. 在读取 JSON 字符串$.getJSON时已经为您创建了一个对象。读取 Javascript 对象。ko.mapping.fromJSONko.mapping.fromJS

有关更多信息,请参见此 JSFiddle:http: //jsfiddle.net/hB3Rm/

本质上,改变这一行:

Listing_ViewModel = ko.mapping.fromJSON(data);

到这一行:

Listing_ViewModel = ko.mapping.fromJS(data);
