I’m looking into integrating Ember with an existing Rails application, to take advantage of Ember’s bindings, events (didInsertElement, etc.) …

Now I don’t want to transfer my erb views to handlebars, but instead I want to create Ember View objects and attach them to various elements already in the DOM. For example, I might have

<html>
  <body>
    <div class="header">

    </div>

    <div class="content">

    </div>

    <div class="footer">

    </div>
  </body>
</html>

and (on DOM ready) create a View for each element:

App.HeaderView = Ember.View.create({
   // capture $('.header') to this
   // console.log(this.$().attr('class')) should then output `header`
});

    Ok the following works but I haven’t fully tested it.

    Inspired by @pangratz’s pull request I extend Ember.View with the following method for 

    Ember.View = Ember.Object.extend(
  /** @scope Ember.View.prototype */ {
  // ........

  wrap: function(target) {
    this._insertElementLater(function() { 
       // Set all attributes name/values from target
       var target_attrs = {};
       var $this = this.$();

       for (var attr, i=0, attrs=$(target)[0].attributes, l=attrs.length; i<l; i++){
          attr = attrs.item(i)
          var attrName = attr.nodeName;
          var attrValue = attr.nodeValue;

          if(attrName === 'id') continue;
          $this.attr(attrName, attrValue);
       }

       // Set HTML from target
       $this.html($(target).html()); 
       Ember.$(target).replaceWith($this); 

    });   
    return this;

  },        

  // ........

});

    Basically it copies the html content of the target element as well as its attributes. Then by just doing 

    App.HeaderView = Ember.View.create().wrap('.header');

    the .header element (that is already in the DOM) is now in App.HeaderView.
