javascript - Backbone.PageableCollection 的 fullCollection 重置后行为怪异

Question

我有一个 Backbone.Pageable 集合，我尝试对其进行过滤，但使用过滤后的值重置该集合，但重置后，collection.fullCollection 的模型比原始模型少一个。

这是我的收藏:

var todoCollection = Backbone.PageableCollection.extend({
  mode:'client',
  search: function(letters){
    var self = this;
    if(letters === "") return this.fullCollection.models;

    var pattern = new RegExp(letters,"i");
    return this.fullCollection.filter(function(data) {
      return pattern.test(data.get("text"));
    });
  }
});

你可以查看这个 fiddle here .

Answer 1

您的搜索函数应返回 todoCollection 的实例。

var todoCollection = Backbone.PageableCollection.extend({

mode:'client',
  search: function(letters){
    var self = this;
    if(letters === "") return this.fullCollection.models;

    var pattern = new RegExp(letters,"i");
    result =  this.fullCollection.filter(function(data) {
      return pattern.test(data.get("text"));
    });
    return new todoCollection(result);
  }
