我将此添加到我的主干扩展.js 文件中，该文件与主干-min.js 位于同一文件夹中......

_.extend(Backbone.View.prototype, {
    getFormData: function(form) { 
        var unindexed_array = form.serializeArray();
        var indexed_array = {};

        $.map(unindexed_array, function(n, i){
            indexed_array[n['name']] = n['value'];
        });

        return indexed_array;
    }
});

但是，当我在视图代码中调用 this.getFormData 时，我得到一个方法未定义的错误。我错过了什么？谢谢你的帮助！

编辑：这是我的看法。我必须取消注释 getFormData 方法才能使其工作。否则它看不到 getFormData ......

define([
        'jquery',
        'underscore',
        'backbone',
        'models/Member',
        'text!templates/memberEditTemplate.html'
    ], function($, _, Backbone, Member, memberEditTemplate) {

    var MemberEditView = Backbone.View.extend({

        el: $("#page"),

        model: 'member',

        initialize: function(args) {
            this.member = new Member({ id: args.id });
            this.member.on('error', this.eventSyncError, this);
            this.member.on('sync', this.eventSyncModelLoaded, this);
            this.member.fetch();
        },

        events: {
          "click #bttnMemberSave": "bttnClickMemberSave"
        },

        eventSyncError: function(model,response,options) {
            console.log('Sync error='+response.statusText);
            $('#server-message').css({'color':'red', 'font-weight':'bold'}).text(response.statusText);
            //$('#server-message').text(response.statusText);
        },

        eventSyncModelLoaded: function(model,response,options) {
            this.render();
        },

        eventSyncModelSaved: function(model,response,options) {
            console.log("Member saved!");
            $('#server-message').css({'color':'green', 'font-weight':'bold'}).text("Member saved!");
            //$('#server-message').text('Member saved!');
            var to = setTimeout(function() { Backbone.history.navigate('members', true); }, 2000);
        },

        bttnClickMemberSave: function() {
            var data = this.getFormData($('#member-form').find('form'));
            this.member.save(data, { success: this.eventSyncModelSaved });
        },

        // getFormData: function(form) { 
        //     var unindexed_array = form.serializeArray();
        //     var indexed_array = {};

        //     $.map(unindexed_array, function(n, i){
        //         indexed_array[n['name']] = n['value'];
        //     });

        //     return indexed_array;
        // },

        render: function() {
            this.member.toJSON();
            var compiledTemplate = _.template( memberEditTemplate, { member: this.member } );
            this.$el.html( compiledTemplate ); 
            return this;
        }

    });

    return MemberEditView;

});

好的，我在 app.js 中的 RequireJS 所需文件数组中添加了主干扩展.js，现在它可以工作了。
