The backbone router isn't working properly
- by user2473588
I'm building a simple backbone app that have 4 routes: home, about, privacy and terms. But after setting the routes I have 3 problems:
The "terms" view isn't rendering;
When I refresh the #about or the #privacy page, the home view renders after the #about/#privacy view
When I hit the back button the home view never renders. For example, if I'm in the #about page, and I hit the back button to the homepage, the about view stays in the page
I don't know what I'm doing wrong about the 1st problem. I think that the 2nd and 3rd problem are related with something missing in the home router, but I don't know what is.
Here is my code:
HTML
<section class="feed">
<script id="homeTemplate" type="text/template">
<div class="home">
</div>
</script>
<script id="termsTemplate" type="text/template">
<div class="terms">
Bla bla bla bla
</div>
</script>
<script id="privacyTemplate" type="text/template">
<div class="privacy">
Bla bla bla bla
</div>
</script>
<script id="aboutTemplate" type="text/template">
<div class="about">
Bla bla bla bla
</div>
</script>
</section>
The views
app.HomeListView = Backbone.View.extend({
el: '.feed',
initialize: function ( initialbooks ) {
this.collection = new app.BookList (initialbooks);
this.render();
},
render: function() {
this.collection.each(function( item ){
this.renderHome( item );
}, this);
},
renderHome: function ( item ) {
var bookview = new app.BookView ({
model: item
})
this.$el.append( bookview.render().el );
} });
app.BookView = Backbone.View.extend ({
tagName: 'div',
className: 'home',
template: _.template( $( '#homeTemplate' ).html()),
render: function() {
this.$el.html(this.template(this.model.toJSON()));
return this;
}
});
app.AboutView = Backbone.View.extend({
tagName: 'div',
className: 'about',
initialize:function () {
this.render();
},
template: _.template( $( '#aboutTemplate' ).html()),
render: function () {
this.$el.html(this.template());
return this;
}
});
app.PrivacyView = Backbone.View.extend ({
tagName: 'div',
className: 'privacy',
initialize: function() {
this.render();
},
template: _.template( $('#privacyTemplate').html() ),
render: function () {
this.$el.html(this.template());
return this;
}
});
app.TermsView = Backbone.View.extend ({
tagName: 'div',
className: 'terms',
initialize: function () {
this.render();
},
template: _.template ( $( '#termsTemplate' ).html() ),
render: function () {
this.$el.html(this.template()),
return this;
}
});
And the router:
var AppRouter = Backbone.Router.extend({
routes: {
'' : 'home',
'about' : 'about',
'privacy' : 'privacy',
'terms' : 'terms'
},
home: function () {
if (!this.homeListView) {
this.homeListView = new app.HomeListView();
};
},
about: function () {
if (!this.aboutView) {
this.aboutView = new app.AboutView();
};
$('.feed').html(this.aboutView.el);
},
privacy: function () {
if (!this.privacyView) {
this.privacyView = new app.PrivacyView();
};
$('.feed').html(this.privacyView.el);
},
terms: function () {
if (!this.termsView) {
this.termsView = new app.TermsView();
};
$('.feed').html(this.termsView.el);
}
})
app.Router = new AppRouter();
Backbone.history.start();
I'm missing something but I don't know what.
Thanks
