gistfile1.js

const element = temp1;

// Create a 'mouseenter' event
const event = new MouseEvent('mouseover', {
    bubbles: true, // Ensures the event bubbles up (if needed)
    cancelable: true, // Allows the event to be canceled
    view: window // Links the event to the window object
});

// Dispatch the event on the element
element.dispatchEvent(event);
