What does it mean when you have action attribute as javascript void(0)
When creating a form in HTML, the action attribute specifies the URL of the page where the form data should be submitted to. However, in some cases, you may want to use JavaScript to handle the form submission instead of submitting it to a server. In these cases, you can use javascript:void(0) as the value of the action attribute. javascript:void(0) is a special syntax in JavaScript that does nothing when executed.
How to use HTML form action with JavaScript
HTML forms allow users to enter and submit data on a webpage. When a user clicks on the submit button, the form data is sent to the server using an HTTP request. The action attribute of the HTML form specifies the URL where the form data should be sent. However, sometimes you might want to perform additional actions with the form data before sending it to the server, such as validating the input or processing it with JavaScript.
