View helper in EJS / JMVC / canJs

Question

Planning to use view helpers in my JMVC application. Tried to implement select_tag helper function in my ejs file but failed to obtain required results. Below is the code

In Controller :

this.choice= [{value: 1,    text: 'First Choice'}, 
              {value: 2,    text: 'Second Choice'} ];                
this.element.html(initView({choice:this.choice}));

In Ejs file :

<%= select_tag('elementId', 1,  this.choice) %>

Reference https://code.google.com/p/embeddedjavascript/wiki/ViewHelpers

Do we need to steal any packages ? is there any sample code ?

Answer 1

To get access to the helpers I did three things...

1. I updated the first line of file jquerypp/view/helpers/helpers.js from:

   steal('jquerypp/view/ejs').then(function($){
   

   to

   steal('jquerypp/view/ejs').then(function(){
   

2. I stole 'jquerypp/view/helpers' in the controller.

3. Finally, in the ejs instead of

   <%= select_tag('elementId', 1,  this.choice) %>
   

   I used

   <%== select_tag('elementId', 1,  this.choice) %>
   

to force ejs to render the select block as part of the page instead of rendering an escaped quoted version.

I guess, you have to include this file: https://code.google.com/p/embeddedjavascript/source/browse/trunk/src/view.js

There are all helpers. So steal it :)
