Displaying Descriptions in AngularJS Select Dropdowns

In AngularJS, creating a user-friendly interface often involves utilizing select dropdowns for data selection. However, a common challenge arises when developers want to display descriptive text in the dropdown while still passing a specific code value to the controller. If you've encountered this issue, you're not alone. Let’s dive into an effective solution that allows you to show descriptions in a select dropdown and pass the corresponding codes to your controller.

The Problem

You might have tried using AngularJS’s ng-options directive to handle this in the past, only to face complications. For instance, you may have set up your transactions like so:

In your template, you used ng-options, but it resulted in incorrect values being passed to your controller, such as an object instead of the expected code. This raised the question: How can I select an item by its code and pass this value to the controller?

The Solution

Step 1: Using ng-repeat

Instead of trying to use ng-options, we can utilize ng-repeat in combination with the ng-value directive. This approach allows you to bind the value correctly while showing the description in the dropdown. Here’s how to implement it:

Controller Code

First, ensure your AngularJS controller is set up correctly. Here’s a refined implementation:

Explanation of the Code

ng-repeat: This directive iterates over each item in the transactionTypes array, allowing you to create an option for each entry.

ng-bind: Displays the description of each transaction type in the dropdown.

Conclusion

By implementing the above solution with ng-repeat, you can successfully display descriptive text in an AngularJS select dropdown while passing the respective codes to the controller. This method avoids the pitfalls of ng-options, making it a straightforward and effective choice for managing dropdown selections in AngularJS applications.

Now that you know how to achieve this, go ahead and implement it in your projects to enhance user experience and functionality!
