Feature: contentFor block helper about express-handlebars HOT 10 CLOSED

Just thought I'd chime in to say I was able to get the sample code above working in my application with a small modification:

    helpers: {
      block: function(name){
        var blocks = this._blocks;
            content = blocks && blocks[name];
        return content ? content.join('\n') : null;
      },
      contentFor: function(name, options){
        var blocks = this._blocks || (this._blocks = {});
            block = blocks[name] || (blocks[name] = []); //Changed this to [] instead of {}
        block.push(options.fn(this));
      }
    }

I'm now able to define a {{{block "pageScripts"}}} in my layout page and fill it with content from my views inside of:

{{#contentFor "pageScripts"}}
<script>
 // my page specific code here
</script>
{{/contentFor}}

Thanks for the sample code to get me jump started!

Thanks! Glad this project is useful to you :)

This feature is definitely something that's perfect for helpers. Here's one way you could go about doing this:

var express = require('express'),
    exphbs  = require('express3-handlebars'),

    app = express(),
    hbs;

hbs = exphbs.create({
    helpers: {
        block: function (name) {
            var blocks  = this._blocks,
                content = blocks && blocks[name];

            return content ? content.join('\n') : null;
        },

        contentFor: function (name, options) {
            var blocks = this._blocks || (this._blocks = {}),
                block  = blocks[name] || (blocks[name] = []);

            block.push(options.fn(this));
        }
    }
});

app.engine('handlebars', hbs.engine);
app.set('view engine', 'handlebars');

// ...

Let me know if this helps (or even works, I didn't test it.)

That's awesome. I'll play with this some tomorrow. Thanks!

Closing this…

It doesn't work for me. It just returns a string inside the HTML and nothing happens

contact.hbs

{{#contentFor "pageScripts"}}
  <script src="js/pace.min.js"></script>
  <script src="js/wow.min.js"></script>
{{/contentFor}}

main.hbs

{{block "pageScripts"}}

from express-handlebars.

Great!

This is working really well. Cheers!!

To properly run js, instead of displaying it,
I needed to change the notation from
{{block "pageScripts"}} to {{{block "pageScripts"}}}
