javascript - how to change value with Ember.js Array forEach?

Question

 self.resultList.forEach(function(item, index, enumerable){
                         console.log(self.resultList);
                         item.id=11;
                         item.get('id');
                     });

the item like this:

if item.id = 11; the exception like this:

Assertion failed: You must use Ember.set() to access this property (of [object Object])

so item.get('id') or item.set('id',11)

the exception like this

Uncaught TypeError: Object # has no method 'get'

is this item not the Ember's Object?so what the item is?

could someone tell me how to change the 'itme.id's value..

Thanks a million

You can use the Ember.set(yourObject, propertyName, value); and Ember.get(yourObject, propertyName); to safely set and get properties.

In your case:

self.resultList.forEach(function(item, index, enumerable) {
    Ember.set(item, "id", 11); 
    Ember.get(item, "id");
});
