Can anyone explain which is better, Handlebar Helpers or Ember Components from a performance side, and use-cases.
For example. I use components for buttons like follow and other elements that might need bubbling up events. Other than this case how can I decide which one to use? Case like characters left, and formatting text to have @mentions and urls
I can speak to the performance but I can comment on when to use Components vs helpers.
Components are helpful in several scenarios:
Multiple elements that work together
When I was writing that code, I got to a point where I needed to write code that would check if certain elements existed on the page. By using the component, I was guaranteed that the elements existed and it was easy to handle their events inside of the component.
When wrapping 3rd party plugins
Here is a good example of this: http://stackoverflow.com/questions/18992613/trying-to-use-foundations-orbit-slider-in-rails-ember-app
Helpers are more like functions inside of your template. They’re great for modifying presentation of values, for example if you wanted to add $ sign to currency fields. This kinds of detail is relevant in presentation but not in the logic, so it makes more sense to create a helper rather than keeping that create another property in the view or a controller.
These are the once that I can think of.
@tarasm Wanna take a guess as to why I need to hit refresh to get my 3rd party plugin to render when navigating by {{linkTo}}?
@jtrinker I was hoping @intuitivepixel was going to take a look at that.
Do you have an example up somewhere where I can take a look at the code?
Interesting. So I added this.$().foundation(); to didInsertElement inside one of the Views and for that view instead of the slider images being stacked, the slider was gone completely. However, when I open inspector the slider renders properly? Here’s the view:
Ew.ConditionsView = Ember.View.extend({
didInsertElement: function() {
$('.hidden-content').hide();
$('.toggle-bar').click(function (ev) {
var t = ev.target
$('#info' + $(this).attr('target')).toggle(500);
return false;
});
this.$().foundation();
}
});
I’d be happy to zip up my files and pass them along if you like. I owe you all one.
