Input Focusing

The JS Library includes the inputFocus() function, a small utility to programmatically focus an input or interactive element.

⚙️ Function Overview

The inputFocus() function checks if a valid element is passed in, and if so, attempts to call .focus() on it.

JavaScript

function inputFocus(element) {
    if (element && typeof element.focus === 'function') {
        element.focus();
    }
}

🚀 Usage

You can use this function to bring focus to form inputs or buttons when certain events occur, such as onclick.

HTML Example

<input type="text" onclick="inputFocus(this)" placeholder="Click me to focus" />

Manual JS Call

const myInput = document.getElementById("my-input");
inputFocus(myInput);

✅ Tip

• Ideal for form UX improvements and accessibility enhancements.
• Useful for re-focusing inputs after user interaction (e.g., validation or tooltips).
• Safe from errors thanks to the type and method existence check.

🔒 Safety

The function gracefully checks:

• If the passed argument is truthy.
• If the focus method exists and is callable.
