Exploring AngularJS: A closer look at ngOptions expressions

I have been struggling to populate a Select element with a list of objects for ngOptions. Despite confirming that the data structure is correct and accessible, I cannot get the Select to show the options. Even when rendering the options expression on the page directly, the data appears fine. Here's an example of the data structure:

{{ form_event.providers.search_terms[form_event.type.toLowerCase()] }}

[{"group": "program", "name": "title"},
 {"group": "program", "name": "aspect_ratio"},
 {"group": "episode", "name": "aspect_ratio"},
 {"group": "episode", "name": "house_id"}]

Based on this data structure, I attempted to use ng-options as follows, but it failed to work:

<select ng-options="term.name group by term.group for term in
    form_event.providers.search_terms[form_event.type.toLowerCase()]">
</select

You can view a fiddle demonstrating the issue here: http://jsfiddle.net/9B3zN/1/

If you have any insights or suggestions, they would be greatly appreciated.

Answer №1

Always remember to include the ng-model attribute when using ng-options with a select element, or else it will not function properly

<select ng-model="selected" ng-options="term.name group by term.group for term in form_event.providers[form_event.type.toLowerCase()]">
    <option value="">-- choose --</option>
</select>
