我有一个我想要获取的骨干集合和模型数组。当我调用fetch时,ajax请求会命中正确的rest端点。但是,我的集合的解析函数永远不会被调用。我不确定json最终会在哪里,但我确实在chrome的网络选项卡中获得了带有效负载的200。我应该这样做吗?我过去做过这个(主干1.0,现在主干1.1)并且它工作正常,所以我不确定问题是什么?
new MonitorCollection(app);
this.collection.fetch(); // this makes the correct ajax call
收集:
define([
'jquery',
'underscore',
'backbone',
'model/monitormodel',
], function ($, _, Backbone, MonitorModel) {
var collection = Backbone.Collection.extend({
initialize: function (app, options) {
this.app = app;
},
url: "api/monitor?since=10",
model: MonitorModel,
parse: function (response) {
console.log(response);
return response;
}
});
return collection;
});
型号:
define([
'jquery',
'underscore',
'backbone',
'view/monitordeviceview',
], function ($, _, Backbone, MonitorDeviceView) {
var model= Backbone.Model.extend({
initialize: function (app, options) {
this.app = app;
this.view = new MonitorDeviceView(this.app);
this.view.render(this);
},
parse: function (response) {
console.log(response);
return response;
}
});
return model;
});

问题是被回送的json无效json:NaN在json中无效。
{
"deviceId": "ac867418c110",
"totalProbeRequestCount": 0,
"errorRate": NaN,
"errorCount": 0,
"succcesRate": NaN,
要帮助调试此添加错误处理程序并阅读链接:
这些链接应该有助于了解骨干网与服务器的交互方式。
var collection = Backbone.Collection.extend({
initialize: function (options) {
this.on("error", this.error, this)
this.fetch();
},

parse: function (data) {
