    The focus() method is a JavaScript method that gives focus to an HTML element, if it can be focused1. The focused element is the element that will receive keyboard and similar events by default2.

    The focus() method is a method of the HTMLElement interface, which means it can be used on any HTML element that inherits from it, such as input, button, select, etc2.

    The syntax of the focus() method is:

    element.focus(options);

    The element is the HTML element to be focused. The options parameter is an optional object that can contain the following properties:

    • preventScroll: A boolean value indicating whether or not the browser should scroll the document to bring the newly-focused element into view. A value of false (the default) means that the browser will scroll the element into view after focusing it. If preventScroll is set to true, no scrolling will occur2.

    • focusVisible: A boolean value that should be set to true to force visible indication that the element is focused. By default, or if the property is not true, a browser may still provide visible indication if it determines that this would improve accessibility for users2. This property is experimental and not widely supported by browsers.

    The focus() method does not return any value.

    Here are some examples of using the focus() method:

    // Give focus to an element by its id
    document.getElementById("myText").focus();

    // Give focus to an element when the page loads
    window.onload = function() {
    document.getElementById("myText").focus();

    Focusable elements can also be focused with a mouse or pointer, by having the autofocus attribute set, or by script, such as with element.focus(). The global tabindex attribute, introduced in attributes, enables elements that otherwise would not be able to receive focus to get focus, usually with the Tab key, hence the name.
    The element.focus() method can be used to set focus to focusable elements. Note that the browsers scroll focused elements into view. For this reason, avoid the use of element.focus({preventScroll:true}), as focusing on a non-visible element will give a bad user experience.
