Answer: To select all on focus in input - we can use jQuery .focus() event.

jQuery focus() Event

The focus() is an event in jQuery. As soon as the user focuses on an input box, this event gets triggered. A function can be attached to it and as soon as the event is fired, this function gets executed.

Syntax:

$(selector).focus();
$(selector).focus(function(){});

The function over here is optional, it can be or cannot be attached to it. Using this function, any task can be performed on the focussed field. For example, the CSS of the input field can be changed or highlighted, etc.

Yes, we can also select the complete text present in the input field with one click with the help of this focus() event. For this, the select() method is used inside the function to be executed. This method helps in selecting the text for a particular selector.

Let's implement both, focus() and select() in an example.
