我正在尝试编辑一个不是我编写的 Backbone.js 应用程序。我的目标是在触发“search：success”时从应用程序视图重置面视图的集合。
第一个文件是app.js文件：

var vent = require('./vent');
var maxListSize = $('.bnr-search-selected-container').data('resultsnumber');
var SearchResults = require('./collections/results');
var Facets = require('./collections/facets');
var Keymatch = require('./models/keymatch');
var Partmatch = require('./models/partmatch');
var Facet = require('./models/facet');
var FacetView = require('./views/facets');
var KeymatchView = require('./views/keymatch');
var PartmatchView = require('./views/partmatch');
var ListView = require('./views/list');
var SearchView = require('./views/search');
var SelectedFacetsView = require('./views/selectedFacets');
var HeaderView = require('./views/header');
var PaginationView = require('./views/pagination');
var EmptyView = require('./views/empty');
var TotalView = require('./views/pageResults');
var fileTypes,
    fileTypesView,
    keymatch,
    partmatch,
    listView,
    languageTypes,
    languageView,
    pagination;
/*
 *   event : event-type (arguments passed) - listeners
 *
 *   Events:

 *       filter:select(type) - list, facets, selected filters
 *       filter:deselect(type) - list, facets, selected filters
 *       search:error(query) - list, search box, keymatch, facets
 *       search:success(facets) - list, search box, keymatch, facets
 *       search:empty(query) - list, search box, keymatch, facets
 *       search:keymatch(keymatch) - keymatch

实际上，在app.js文件中，对于下面的部分：

if (data.facetsDocType.length > 0 && !$('.bnr-facet-file-type-block').data('rendered')) {
            $('.bnr-facet-file-type-block').data('rendered','true');
            $('.bnr-facet-file-type-block, .bnr-facet-file-type-line').show();
            fileTypes = new Facets(data.facetsDocType);
            fileTypesView = new FacetView({
                collection: fileTypes,
                el: $('#bn-search-facets-file-type'),
                facets: window.Banner.Search ? window.Banner.Search.facetsAndItems : undefined,
                initialized: positionControls
            });
        } else if (data.facetsDocType.length <= 0) {
            $('.bnr-facet-file-type-block, .bnr-facet-file-type-line').hide();
        }

如果fileTypesView已经被渲染了，我希望能够更新它的当前集合。我一直在努力解决这个问题，因为有3个不同的facet视图都使用facets.js视图。所以我主要想知道，如果视图已经被渲染了，我如何调用它，并用新数据触发集合重置。
