如何删除集合中的最后一个模型?
if (this.Collection.models.length < newValue) {
console.log('adding');
this.Collection.models.add();
} else {
console.log('removing');
// this isnt working, by selecting it by the current collection array index
// basically this.Collection.remove([this.Collection.models.length-1])
//this.measuresCollection.models.get('beats').remove(this.measuresCollection.models[i].get('beats')[this.measuresCollection.models[i].get('beats').length]);
}
我不知道id,所以我只想删除最后一个。
