我只是努力使用下划线获取主干集合。
var collection=Backbone.Collection.extend({
model:someModel,
getModelEntry : function(id){
return this.get(id);
//returns undefined
}
})
尝试2:
var collection=Backbone.Collection.extend({
model:someModel,
getModelEntry : function(id){
var model = this.where({id:id})[0];
//here I got model
return model.get("attr");
//returns undefined
}
});
使用get in collection有什么不对?
get在实例上工作得很完美!
var coll=new collection;
coll.get(id); //working fine
答案 0 :(得分:0)
到目前为止,我看得很清楚。检查您要查找的模型的ID是否存在于您的集合中。添加如下所示的内容,看看会发生什么
getModelEntry : function(id){
var model = this.get(id);
if(model == undefined) {
console.log("id: ",id);
console.log("collection: ",JSON.stringify(this.models));
} else {
console.log(model.get('name'));
}
}
