Question

Which of the following JavaScript event handlers is triggered when the mouse pointer leaves an HTML element?

• A. onmouseover
• B. onmouseout
• C. onchange
• D. onload

Hint:

To create dynamic hover effects without CSS transitions, pair onmouseover (to add styles/images) with onmouseout (to restore original styles/images).

Answer 1

The Correct Option is B

Step 1: Understanding JavaScript Event Handlers:
Event handlers are properties of HTML elements that execute a designated block of JavaScript code when a specific asynchronous event (like a click, hover, or focus change) occurs.

Step 2: Analyzing Mouse-Specific Events:

• onmouseover: Triggers immediately when the user's mouse pointer enters the bounding box of the HTML element.
• onmouseout: Triggers immediately when the user's mouse pointer leaves or moves outside the boundaries of the HTML element.
• onchange: Triggered when the value of an input element changes (commonly used on select drop-downs, text inputs, or radio buttons).
• onload: Fires when the browser has completed loading the document object model, styles, and image assets. Therefore, onmouseout is the handler designed specifically to listen for the cursor departing from an element.
