backbone.js - 具有requirejs的主干-传递到 View 时“未定义模型”

从另一个视图中渲染视图时，出现JS错误“未捕获的ReferenceError：未定义模型”。

我有一个列表视图：

define([
    'jquery',
    'backbone',
    'underscore',
    'views/action',
    'collections/actionlist',
    'text!templates/actionlist.html'],

function($, Backbone, _, actionView, actionList, template){

var someactions = [
    { the_action: "Contact 1", due: "1, a street, a town, a city, AB12 3CD", list: "0123456789" },
    { the_action: "Contact 2", due: "1, a street, a town, a city, AB12 3CD", list: "0123456789" },
    { the_action: "Contact 3", due: "1, a street, a town, a city, AB12 3CD", list: "0123456789" }
];

var actionlistView = Backbone.View.extend({

    el: '#main',
    template: _.template(template),

    initialize: function () {
        this.collection = new actionList(someactions);
        this.collection.on("add", this.renderAction, this);
    },

    events: {
        "click #add": "addAction"
    },

    render: function () {
        var $el = $('#main')

        $el.html(this.template);

        // Get Actions
        _.each(this.collection.models, function (action) {
            this.renderAction(action);
        }, this);

    },

    renderAction: function (action) {
        var theAction = new actionView({ model: action });
        $('#actionlist').append(theAction.render().el);
    },

    addAction: function(e){
        e.preventDefault();
        var formData = {};

        $('#addAction').children("input").each(function(i, el){
            if ($(el).val() !== "") {
                formData[el.id] = $(el).val();
            }
        });

        this.collection.create(formData);
    }
});

return actionlistView;
});

在renderAction函数中调用的actionView为：

define([
    'jquery',
    'backbone',
    'underscore',
    'models/action',
    'text!templates/action.html'],

function($, Backbone, _, actionModel, template){

var actionView = Backbone.View.extend({
    tagname: 'li',
    template: _.template(template),

    render: function () {
        this.$el.html(this.template(this.model)); // ERROR OCCURS ON THIS LINE
        return this;
    }
});

return actionView;
});

我在“ this。$ el.html（this.template（this.model））;”行上收到错误。尝试呈现第一个actionView时。

我很沮丧！我想念什么？

根据要求的ActionView模板：

    <b class="name"><%=model.get("the_action")%></b> - <%=model.get("due")%> -
    <em>from <%=model.get("list")%></em>

最佳答案

最好在模板中调用model.toJSON（）并在模板中引用json。

由此：

this.$el.html(this.template(this.model));

对此：

this.$el.html(this.template(this.model.toJSON()));

然后直接在模板中引用“ due”和“ list”：

<b class="name"><%=the_action%></b> - <%=due%> -
    <em>from <%=list%></em>
