Issue with Triggering Events in Backbone.js View

I'm encountering issues with my backbone.js view events not triggering. The #login-button doesn't respond when clicked.

Additionally, I'm utilizing iCanHaz (http://icanhazjs.com/) to load the templates.

Below is my JavaScript code:

$(function() {
 var router = new App.Router;
 Backbone.history.start();
});

App.Router = Backbone.Router.extend({
 routes: {
    "login": "login"
 },

login: function() {
    var view = new App.Views.LoginView;
 }
});

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

 el: '#login',

 initialize: function() {

    _.bindAll(this, 'render', 'validateLogin');
    this.render();

 },

 render: function() {
    App.Stage.html(ich.loginView());
 },

 events: {
    'click button#login-button' : 'validateLogin'
 },

 validateLogin: function(event) {
     console.log("validateLogin fired.");
 }

});

Here is my markup using ICanHaz.js:

<script id="loginView" type="text/html">
        <div data-role="page" id="login" class="container">
            <div class="hero-unit">
                <div class="row-fluid">
                    <div class="span12">
                        <div class="form-horizontal">
                        <fieldset>
                            <legend>Please login to continue</legend>
                            <div class="control-group">
                            <label class="control-label" for="username">Username</label>
                            <div class="controls">
                                <input type="text" class="input-xlarge" id="username">
                            </div>
                            </div>

                                <div class="control-group">
                            <label class="control-label" for="password">Password</label>
                            <div class="controls">
                                <input type="password" class="input-xlarge" id="password">
                            </div>
                            </div>

                                <div class="form-actions">
                        <button id="login-button" class="btn btn-primary btn-large">Login</button>
                    </div>
                        </fieldset>
                        </div>
                    </div>
                </div>
            </div>
        </div>
    </script>

Answer №1

After some troubleshooting, I finally resolved the issue. It turned out that Backbone was attaching the events to the element before it was even created. By calling this.setElement('#login') within the callback function for the asynchronous iCanHaz call, everything started working seamlessly. Referencing the backbone.js documentation, here is an excerpt:

setElement [view.setElement(element)]

The documentation states, "If you need to apply a Backbone view to a different DOM element, utilize setElement, which not only establishes the cached $el reference but also moves the view's delegated events from the old element to the new one."

Answer №2

In my opinion, it seems like you might need to adjust how the 'el' property of the View is being utilized. Consider updating the property to directly reference the jQuery DOM object rather than solely relying on the ID, as shown below:

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

 el: $('#login')

...
