_.渲染主干视图时bindAll不工作

bindAll 除了处理其上下文外,还具有其他功能。在这种情况下,以下实现不起作用。

2. _.bindAll (this, 'render'); 你能看到函数do中的上下文吗? $(this.el) 是 undefined _bindAll ?

3. ol 列表

   $(this.el).append('idCurso->', cursoModelo.get('idCurso'),' titulo-> ', cursoModelo.get('titulo'));
   $(this.el).append('hola caracola');`. 
   

HTML

<ol id="ListaLibros"/>

JS公司

// create a view to print the model data in the html
var ListaLibrosView = Backbone.View.extend({
  el: '#ListaLibros',
  initialize: function() {
    this.collection = cursoCollection;

    _.bindAll(this, 'render');

    this.render();
  },
  render: function() {
    console.log("funcion render");
    var listaLibrosLi = '';

    this.collection.each(function(cursoModelo) {
      $(this.el).append('idCurso->', cursoModelo.get('idCurso'), ' titulo-> ', cursoModelo.get('titulo'));
      $(this.el).append('hola caracola');
    });
  }
});
