Pressing the key N will select the next Vue component. However, if you are typing in an input field and press the key N, it still "selects" the next component. This behavior should be disabled when focused on an input.
In my Vue application with a complex hierarchy of hundreds of components, I'm wondering if there is a standard pattern or library available for handling keyboard input separately among components?
If you want to access the currently focused element in your document, you can use document.activeElement. To specifically target text input elements such as input, textarea, or elements with the attribute contenteditable, you can handle key events like this:
const handleKeyPress = (event) => {
const textInputs = ['INPUT', 'TEXTAREA'];
const isTextInput = document.activeElement === event.target &&
(textInputs.includes(event.target.tagName) ||
event.target.hasAttribute('contenteditable'));
if (!isTextInput && event.code === 'KeyN') {
// Your logic here
}
};
To ensure proper validation in your onKey method, consider checking for the presence of a type attribute on the target element. Remember, only input tags come with a type attribute by default.
const onKey = (e) => {
if (e.target.type !== undefined && e.code === 'KeyN') {
active.value = (active.value + 1) % 3;
}
};
