Question

Clear the contents of a textarea once user has finished inputting

I am currently working with AngularJS to develop a basic Single Page Application (SPA).

Within this application, there is a <textarea> element that displays initial content from a binding:

<textarea>{{activeField.rawContent}}</textarea>

The goal is for users to be able to modify the text in the textarea and then save it to a database.

However, I have encountered an issue where once any input is entered, the textarea no longer displays the updated content from the binding, even if the activeField.rawContent data has been changed.

How can I prevent this behavior from happening?

Answer №1

The {{}} is actually referring to ng-Bind in the background, which facilitates one-way data binding.

ng-model, on the other hand, enables two-way data binding.

In your code snippet, you are essentially just inserting text content rather than establishing a binding with the data. It is recommended in the Angular documentation to utilize ng-model for this scenario. Consider changing it to:

<textarea ng-model="activeField.rawContent"></textarea>

For further insights, you can refer to this discussion thread, ng-model, and ng-bind.

When connecting editable information to input or textarea elements, it is important to utilize the ng-model directive. This directive links to the element's change events and updates the model with any changes made.

To achieve this, you can use the following code:

<input type="text" ng-model="editableField.value"></input>
