I have a very simple web page which is using backbone simply to load a view from a template file:
<div id="content"></div>
<script src="js/vendor/json2.js"></script>
<script src="js/vendor/jquery-2.0.2.min.js"></script>
<script src="js/vendor/underscore-min.js"></script>
<script src="js/vendor/backbone-min.js"></script>
<script src="js/flight-match-form.js"></script>
<script type="text/template" id="template-flight-match">
<section id="form-search" class="content-inner clearfix">
<div id="date-container" class="search-row clearfix">
<label class="search-label" for="date">Travel Date</label>
<img src="images/structure/icon-calendar.png" alt="calendar" class="calendar">
<span class="help-text" id="date-unknown">don't know it?</span>
</div>
<div id="flight-container" class="search-row clearfix">
<label class="search-label" for="date">FLIGHT #</label>
<input type="text" class="search-input" id="input-flight" pattern="[a-zA-Z0-9]+">
<span class="help-text" id="date-unknown">don't know it?</span>
</div>
<button id="button-match">
Match
<img src="images/structure/icon-arrow.png" height="15" width="20" alt="Submit Arrow">
</button>
</section>
</script>
and in flight-match-form.js, I simply say:
$(document).ready(function(){
var MatchView = Backbone.View.extend({
initialize: function(){
this.render();
},
render: function(){
// Compile the template using underscore
var template = _.template( $("#template-flight-match").html(), {} );
// Load the compiled HTML into the Backbone "el"
this.$el.html( template );
}
});
var matchView = new MatchView({ el: $("#content") });
});
This works great, and all I really wanted to do next was to get all that html out of a script tag and into a proper HTML file, where I think it belongs. So, does anyone know the simplest way to do this?
I tried to follow this tutorial, and it lead me down this big rabbit hole where I ended up using require.js and the text module, and a router, and two new js files (main and app), along with a view and a template. I'm currently getting an error in the view stating that Backbone cannot read property 'view' of undefined. This is my code:
In index.html, I include require.js, and make it reference main.js as the inital file:
then in main.js, I specify a template directory, and send it off to app.js:
require.config({
paths: {
jquery: 'vendor/jquery/jquery-2.0.2.min',
underscore: 'vendor/underscore/underscore-min',
backbone: 'vendor/backbone/backbone-min',
templates: '../templates'
}
});
require([
'app',
], function(App){
App.initialize();
});
In app.js, I initialize the router:
define([
'jquery',
'underscore',
'backbone',
'router', // Request router.js
], function($, _, Backbone, Router){
var initialize = function(){
// Pass in our Router module and call it's initialize function
Router.initialize();
};
return {
initialize: initialize
};
});
and in router.js, I set up a route for my view:
// Filename: router.js
define([
'jquery',
'underscore',
'backbone',
'views/search/SearchFormView'
], function($, _, Backbone, SearchFormView) {
var AppRouter = Backbone.Router.extend({
routes: {
// Define some URL routes
'search': 'SearchFormView'
}
});
var initialize = function(){
var app_router = new AppRouter;
app_router.on('route:SearchFormView', function(){
// Call render on the module we loaded in via the dependency array
var searchView = new SearchFormView();
searchView.render();
});
Backbone.history.start();
};
return {
initialize: initialize
};
});
Lastly, I just create that view, which will load my template:
define([
'jquery',
'underscore',
'backbone',
'text!templates/search/search-form-template.html'
], function($, _, Backbone, searchFormTemplate){
var SearchFormView = Backbone.View.extend({
initialize: function(){
this.render();
},
render: function(){
// Compile the template using underscore
var template = _.template( $("#template-flight-match").html(), {} );
// Load the compiled HTML into the Backbone "el"
this.$el.html( template );
}
});
return SearchFormView;
});
but it's not working, and I can't figure out why. Any help is much appreciated. Apologize for the excessive amount of code, but all of it seems to be necessary just to load this stuff the proper way.
You can place the <script> tags, containing your JavaScript, anywhere within your web page, but it is normally recommended that you should keep it within the <head> tags. The <script> tag alerts the browser program to start interpreting all the text between these tags as a script.
JavaScript in <head> or <body> You can place any number of scripts in an HTML document. Scripts can be placed in the <body> , or in the <head> section of an HTML page, or in both.
Always declare JavaScript variables with var , let , or const . The var keyword is used in all JavaScript code from 1995 to 2015. The let and const keywords were added to JavaScript in 2015. If you want your code to run in older browsers, you must use var .
At the moment you actually have a problem with your config. Backbone is not an AMD module, so you have to use the shim option of requirejs
. Well, the example speaks for itself as it's about Backbone.
