How to prevent double clicks with ember.js? - ember.js

Question

I'm trying to figure out the idiomatic way to prevent a button from being clicked multiple times.
Imagine I have a simple controller action like so ...
var FooController = Ember.ObjectController.extend({
actions: {
go: function() {
console.log("done!");
}
}
});
and in my template I have a button defined like so ...
<button {{action go}}>Click Me Fast</button>
Does the action have an option to disable it immediately / making it so only once true event will be handled by the controller (until it's disabled for example)
Edit
I'm looking for a long term / multi use solution. One idea I'm thinking about is creating a special ember-component called "button-disable" that would allow me to create a custom button type that generally disables after a single click -but will still allow me to bubble up events to a parent controller. This feels a little heavier weight than I'd like so if another option exists, or if someone has created an addon for just this - let me know

Answer 1

As a one-off, if you bind the disabled attribute on your button like so
<button {{action go}} {{bind-attr disabled=actionPerformed}}>
and then set up your controller like
var FooController = Ember.ObjectController.extend({
actionPerformed: false,
actions: {
go: function() {
this.set("actionPerformed", true);
console.log("done!");
}
}
});
then the button will become disabled after you click it once
If you want a reusable component I'd borrow the spinner button from http://emberjs.com/guides/cookbook/helpers_and_components/spin_button_for_asynchronous_actions/ and tweak it as you need.
So your JS would be along the lines of
window.SpinEg = Ember.Application.create({});
SpinEg.ApplicationController = Ember.Controller.extend({
isLoading:false,
buttonText:"Submit",
actions:{
saveData:function(){
var self = this;
var saveTime = Ember.run.later(function(){
self.set('isLoading', false);
}, 1000);
}
}
});
SpinEg.SpinButtonComponent = Ember.Component.extend({
classNames: ['button'],
buttonText:"Save",
isLoading:false,
actions:{
showLoading:function(){
if(!this.get('isLoading')){
this.set('isLoading', true);
this.sendAction('action');
}
}
}
});
The template for your component would be
<script type='text/x-handlebars' id='components/spin-button'>
<button {{bind-attr id=id}} {{action 'showLoading'}}>
{{#if isLoading}}
<img src="http://i639.photobucket.com/albums/uu116/pksjce/spiffygif_18x18.gif"></img>
{{else}}
{{buttonText}}
{{/if}}
</button>
</script>
and you would then just include the following where you need the button to appear
<script type='text/x-handlebars' id='application'>
{{spin-button id="forapplication" isLoading = isLoading buttonText=buttonText action='saveData'}}
</script>
