If you are working with MathLive, you will find that this library is very powerful and capable of adding mathematical capabilities to text editors. However, you might want specific functionalities to only be displayed when the element you are focusing on is active. When using mathematical editors, it is possible that the keyboard or menu may not be readily accessible, and the user might need to focus more on accessing them. In such a case, having specific behaviors to indicate the menu and keyboard only when in focus can enhance the user's UX.
In normal conditions, MathLive allows you to utilize different keyboards and menus using a simple API that can be either active or inactive. In this situation, it is necessary to be aware of how this functionality is implemented to match your requirements and, in turn, provide users with a good experience. Generally, this feature is accessible, but it is better to be familiar with the related codes to ensure you can adjust and appropriate behavior to the system.
Implementing such functionality requires some JavaScript that works on focus and blur events. Below is an example code that demonstrates how you can achieve this in the editor itself. We will use fundamental principles to make your implementations easier to apply to the system:
The implementation of this feature requires a portion of JavaScript that interacts with focus and blur events. Here is a sample code demonstrating how this functionality can be executed in your editor:
<!-- HTML Structure -->
<div id="math-editor"></div>
<script>
const mathfieldElement = document.getElementById('math-editor');
const mf = new MathfieldElement(mathfieldElement);
// Add Event Listeners
mf.addEventListener('focus', () => {
mf.setOptions({virtualKeyboardMode: 'on'});
});
mf.addEventListener('blur', () => {
mf.setOptions({virtualKeyboardMode: 'off'});
});
</script>
<div id="math-editor"></div> This line shows a
div with id "math-editor" that can serve as a container for the math editor.const mathfieldElement = document.getElementById('math-editor'); This line selects the element
div in JavaScript and assigns it to a variable.const mf = new MathfieldElement(mathfieldElement); This line creates a new instance of Mathfield using the selected element.
mf.addEventListener('focus', () => { ... }); This line adds an event listener for when the math field is focused and enables the keyboard.
mf.addEventListener('blur', () => { ... }); This line adds an event listener for when the element loses focus to disable the keyboard.
