将控制器属性传递给Emberjs中的把手助手

Question

I have a property in my controller and i want to pass this property to my custom handlebar helper

App.AppController = Ember.Controller.extend({

   json: //this property contain some string
});

and my helper is like this :

 Handlebars.registerHelper('NGRID', function(json) {
   console.log('im calling in ngrid');
 });

and my view is something like this :

<script type="text/x-handlebars" data-template-name="table">
     {{!-- Table here --}}
     {{NGRID json}}
</script>

but {{NGRID json}} pass string json to handlebars helper and i need to pass content of json peroperty .

Answer 1

Ember has its own template mechanism. You need to use registerBoundHelper for passing object

Ember.Handlebars.registerBoundHelper('NGRID', function(json, options){
    console.log('NGRID json:' + json);
});
