What is the best way to specify option values for selection in AngularJS?

...while still maintaining the model bindings?

I currently have a select menu set up like this:

<select class="form-control" ng-model="activeTask" ng-options="task.title for task in tasks"> </select>

When an option is selected, it displays some text like this:

<span>{{activeTask.title}}</span>

The Projects resource fetches some JSON data (which is functioning correctly):

function TimerCtrl($scope, Projects) {
    $scope.projects = Projects.get({}, {isArray:true}, function(projects) {
        $scope.tasks = $scope.projects[0].tasks;
        $scope.activeProject = $scope.projects[0];
        $scope.activeTask = $scope.tasks[0];
    });
}

This is the Projects service implementation (also working fine):

angular.module('projectServices', ['ngResource']).
factory('Projects', function($resource) {
    return $resource('data/projects.json', {}, {
        get: {method:'GET', isArray:true}
    });
});

And here is the JSON data structure (all good as well):

[
    {
        "title":"Chores",
        "url_title":"chores",
        "category":"Home",
        "tasks": [
            {"title":"Cleaning", "url_title":"cleaning"},
            {"title":"Yard Work", "url_title":"yard_work"},
            {"title":"Walking the Dogs", "url_title":"url_title"}
        ]
    },
    {
        "title":"Personal Website",
        "url_title":"personal_website",
        "category":"Work",
        "tasks": [
            {"title":"Design", "url_title":"design"},
            {"title":"Front End Dev", "url_title":"front_end_dev"},
            {"title":"Node Dev", "url_title":"node_dev"},
            {"title":"PHP Dev", "url_title":"php_dev"}
        ]
    }
]

Everything is functioning smoothly with the default numeric values generated by Angular. However, my challenge lies in needing the value to be the URL-friendly string task.url_title, while displaying the option text as task.title.

Any assistance on this matter would be highly appreciated. I could really use a beer right now!

So, here's the solution I implemented:

I opted to utilize the entire task object as the value like so:

<select class="form-control" ng-model="activeTask" ng-options="task as task.title for task in tasks">

This approach allowed me to easily bind the span element to display the task title, rather than the url_title:

<span>{{activeTask.title}}</span>

A special thanks goes out to @sza for guiding me in the right direction. His suggestions can be found in the comments section of the correct answer.

Answer №1

To modify the comprehension expression, use:

ng-options="task.url_title as task.title for task in tasks"

See Demo in Action

Answer №2

To successfully implement this feature, make sure to utilize the ng-options="..." directive in your code. Additionally, remember to include the ng-model="..." directive as well for proper functionality.

Consider the following example:

<select ng-options="ITEM.VALUE as ITEM.LABEL for ITEM in ITEMS" ng-model="val">
  <option>placeholder value can be inserted at the beginning of the element</option>
</select>
