在我的主干视图中,我有:

noteTemplate: _.template($('#note-template').html()),

这是抛出这个错误。模板是:

<script type="text/template" id="note-template">
    <div class="reminder">
        <div class="reminder-hover">
            <div class="title"><%= title %></div>
            <div class="created">Created 3 days ago <span class="pull-right"> In 3 hours</span></div>
        </div>
        <span class="id" style="display: none;"><%= id %></span>
    </div>
</script>

我很困惑,因为这在我的控制台中有效:

>> _.template($('#note-template').html());
function (n){return e.call(this,n,w)}

这是完整的代码:

App.Views.Index = Backbone.View.extend({

    el: $("div.reminders"),
    todays : $("span.today"),
    tomorrows : $("span.tomorrow"),
    weeks : $("span.week"),
    all_times : $("span.all-time"),

    noteTemplate: _.template($('#note-template').html()),


    events: {
        "click .reminder" : "editNote",
        "click .newNote"  : "newNote"
    },

    initialize : function() { 
        _.bindAll(this, 'render');
        this.notes = this.options.notes;
        this.listenTo(this.model, 'change', this.render);
    },

    render : function() {
        // Hide things related to editing a note 
        this.$("[name=content]").hide().val("");
        this.$("[name=title]").hide().val("");
        this.$("save1").hide();
        this.$("close1").hide();

        // Fill in content
        this.$el.html( this.noteTemplate( this.model.toJSON() ) );
        this.$todays.html( collection.getTodays.length );
        this.$tomorrows.html( collection.getTomorrows.length );
        this.$weeks.html( collection.getWeeks.length );
        this.$all_times.html( collection.getAllTimes.length );
        return this;
    },

    editNote : function() {
        this.goTo("notes/"+this.model.id);
    },

    newNote : function(){
        this.goTo("newNote");
    }

});

与其在定义方法时尝试缓存注释模板 HTML,不如在初始化视图时进行。

initialize : function() { 
    // ...
    this.nodeTemplate = _.template($('#note-template').html());
}

您很可能在加载 DOM(以及模板)之前定义视图。

另一种解决方案是移动调用视图上方的标记脚本,如下所示(我正在使用玉)

script#page-thumb(type='text/template')
    .page-thumb-container.relative
      .page-thumb
        .image
          figure
            img(src='{{ image }}' , width='80px',height='60px' , data-id='{{ id }}')
          span.title {{ title }}
      .page-dragger.absolute

script(src='js/src/views/PageThumbView.js')
