I added a combobox in a list-table template

<script type="text/x-handlebars-template" id="listItemTmpl">
    <tr>                             
        <td>{{partNo}}</td>
        <td>
             <select name="selectCombo" id="selectCombo">
                    {{#each chks}}
                    <option value='{{this.id}}' {{#if(this.id==status)}}selected{{/if}}>{{this.name}}</option>
                    {{/each}}
                </select>
        </td>
    </tr>

</script>

so my chk model is; 

chkModel = Backbone.Model.extend({
   urlRoot:url,
   defaults:{
        name:""
   }

});

But now I get a error like this;

Uncaught Error: Parse error on line 13:
...ue='{{this.id}}' {{#if(this.id==status)}
-----------------------^
Expecting 'ID', got 'undefined'

so what can I do?

So it seems you want to populate the select box with a bunch of depending on the model attributes. Handlebar.js seems to support looping so try the following. Note that I think you have an incorrect structure with Models and Collections. From what I understand you have a model and one of its attributes is a collection. Check the backbone documentation to see how to get and set attributes. Use the proper method, otherwise events will not get triggered.

I was going to try and post some code but I fear I will get it wrong since I don't understand the context and everything you are doing.

Take a bit of time and go through this tutorial to better understand how you should be doing things.

Comment if you need help after reading the blog

To add to this. The below code is a handlebar.js sample that can loop through JSON items (in your case they will be model attributes)

{{#if items}}
 <ul>
    {{#each items}}
      <li>
        {{this.name}}
      </li>
    {{/each}}
  </ul>
{{/if}}

  • I think you can remove the 'this.' in the templates and use 'id' and 'name'. Try that – Xerri Dec 07 '12 at 13:45
