I am new to backbone and I am looking for a way for my button to be triggered when I press Enter as well as clicking. Currently showPrompt
only executes on a click. What is the cleanest DRYest way to have it execute on pressing Enter as well, preferably only for that input field.
(function () {
var Friend = Backbone.Model.extend({
name: null
});
var Friends = Backbone.Collection.extend({
initialize: function (models, options) {
this.bind("add", options.view.addFriendLi);
}
});
var AppView = Backbone.View.extend({
el: $("body"),
initialize: function() {
this.friends = new Friends(null, {view: this});
},
events: {
"click #add-friend": "showPrompt",
},
showPrompt: function () {
var friend_name = $("#friend-name").val()
var friend_model = new Friend({ name:friend_name });
this.friends.add( friend_model );
},
addFriendLi: function (model) {
$("#friends-list").append("<li>" + model.get('name') + "</li>");
}
});
var appView = new AppView;
}());
Also where can I read more about this kind of event binding? Do backbone events differ from JS or jQuery events in how they're defined?
Assuming that you are using
jQuery
forDOM manipulation
, you can create your own "tiny" plugin that fires the Enter event in the inputs. Put it in yourplugins.js
or whatever setup scripts file you have:Now that you have created this "enter" plugin, you can listen to enter events this way:
