Question

我在尝试在获取集合后调用success回调时遇到问题。以下是该集合中的代码，问题是激发executeLongPolling

(function() {
window.StatusCollection = Backbone.Collection.extend({
    longPolling : false,
    intervalSeconds : 20,
    model: Status,
    url: function(){
        return this.project.id + 'statuses/';
    },
    initialize : function(){
        _.bindAll(this);
    },
    startLongPolling : function(invervalSeconds){
        this.longPolling = true;
        if( invervalSeconds ){
            this.invervalSeconds = invervalSeconds;
        }
        this.executeLongPolling();
    },
    stopLongPolling : function(){
        this.longPolling = false;
    },
    executeLongPolling : function(){
        var that = this;
        this.fetch({
            success : function(collection, response, options) {
                that.onFetch();
            }
        });
    },
    onFetch : function () {
        if( this.longPolling ){
            setTimeout(this.executeLongPolling, 1000 * this.intervalSeconds);
        }
    }
}); })();

令人惊讶的是，当我添加更新选项时，它会起作用并调用行that.onFetch()：

executeLongPolling : function(){
        var that = this;
        this.fetch({ update: true,
            success : function(collection, response, options) {
                that.onFetch();
            }
        });
    },

我正在使用backbone-0.9.10。和骨干关系-0.7.0

任何想法有什么不对？谢谢！

在寻找我的问题的解决方案时遇到了你的问题，只是添加到我的收藏（我不使用fetch）似乎在从0.9.2升级到0.9.10后被打破 Anywho，只是看了你的问题，可能与0.9.10中的fetch更改有关看看这些：

Backbone throwing collection[method] function error https://github.com/addyosmani/backbone.paginator/issues/134

或许Backbone-relational还没有完全适用于0.9.10这一事实 https://github.com/PaulUithol/backbone-tastypie/pull/25

Backbone成功回调未调用
