i have code in :

node.js // mongodb database

server.js

app.get('/class',function(req, res) {
console.log('show all data in class');
db.collection('ak_classroom', function(err, collection) {
    collection.find().toArray(function(err, items) {
        res.send(items);
    });
}); 
});

main.js

var AppRouter = Backbone.Router.extend({
routes: {
"class" : "show_class",
},
show_class: function(page) {
    var p = page ? parseInt(page, 10) : 1;
    var classList = new ClassCollection();
    classList.fetch({success: function(){
        $("#content").html(new classView({model: classList, page: p}).el);
    }});
    this.headerView.selectMenuItem('home-menu');
 },
});

utils.loadTemplate(['show_class_View'], function() {
app = new AppRouter();
Backbone.history.start(); 
});

in models.js

//=== for get my link database mongodb get /class

window.class = Backbone.Model.extend({
urlRoot: "/class",

idAttribute: "_id",
//my default variable in databsae
defaults: {
    _id: null,
    sch_id : "",
cls_name: "",
    cls_description: "",
    cls_active: "",
}}); 
//get collection database 
window.classCollection = Backbone.Collection.extend({

model: Class,
url: "/class" });

in classlist.js

window.classView = Backbone.View.extend({

initialize: function () {
    this.render();
},

render: function () {
    var class = this.model.models;
    var len = class.length;
    var startPos = (this.options.page - 1) * 100;
    var endPos = Math.min(startPos + 100, len);

    $(this.el).html('<table id="content"><thead><tr><th>ID School</th><th>Name class</th><th>Description</th></tr></thead></table>');

    for (var i = startPos; i < endPos; i++) {
        $('.content', this.el).append(new show_class_View({model: class[i]}).render().el);
    }

    return this;
}
});


window.show_class_View = Backbone.View.extend({
tagName: "tr",

initialize: function () {
    this.model.bind("change", this.render, this);
    this.model.bind("destroy", this.close, this);
},

render: function () {
    $(this.el).html(this.template(this.model.toJSON()));
    return this;
}
});
