When the input field is of type = 'file' then it allows you to select any document file (.pdf, .doc, .jpg, .png, etc.). Therefore, there should be a way to clear the selected file just in case the user selects the wrong file. For this, we can set the input 'value' attribute as none, i.e., val(' '). Hence, this will allow the input field to reset back to the initial.

Syntax:

 $('selector').val('');

We can also use the jQuery reset() method for the same. Let's use this method for resetting the complete form back to default.

jQuery reset() Method

This is a jQuery built-in method, which helps clear up all the input values within a form in one go.

Syntax:

$(selector)[0].reset();

The form is selected using the appropriate selector and then it is reset using the reset() method. This reset method can be set as a function for a click event of a button.

Let's understand this better with the help of an example:
