How to get form data using JavaScript/jQuery?

The serializeArray() method creates an array of objects (name and value) by serializing form values. This method can be used to get the form data.

Syntax:

$(selector).serializeArray()

Parameter: It does not accept any parameter.

Return Value: It returns all the value that is inside the inputs fields.

Example:

<!DOCTYPE html> 
<html> 
   
<head> 
    <script src= 
"https://ajax.googleapis.com/ajax/libs/jquery/3.4.0/jquery.min.js"> 
    </script> 
      
    <script> 
        $(document).ready(function() { 
            $("button").click(function() { 
                var x = $("form").serializeArray(); 
                $.each(x, function(i, field) { 
                    $("#output").append(field.name + ":" 
                            + field.value + " "); 
                }); 
            }); 
        }); 
    </script> 
      
    <style> 
        #GFG { 
            width: 300px; 
            padding: 50px; 
            height: 150px; 
            border: 2px solid green;

    </style> 
</head>
