Final answer:
The statement is false. Server-side validation is still needed. Server-side validation is necessary even if client-side JavaScript checks are present, to ensure security and data integrity.
Step-by-step explanation:
The statement is false.
While JavaScript checks can provide some level of validation on the client side, server-side validation is still needed. Client-side validation using JavaScript can easily be bypassed or disabled by malicious users. Server-side validation ensures that the input data is validated and sanitized on the server before it is processed, providing an additional layer of security and reliability.
For example, if a form is submitted without JavaScript enabled or if the user intentionally sends a crafted request to bypass the client-side checks, server-side validation will prevent any malicious or incorrect data from being stored or processed on the server.
Server-side validation is necessary even if client-side JavaScript checks are present, to ensure security and data integrity.
The statement that server side validation is not needed if JavaScript checks are used to validate user input is false. While client-side validation can improve the user experience by providing immediate feedback, it is not a secure method to ensure data integrity because JavaScript can be disabled or bypassed by an end user. Therefore, server-side validation is crucial as it allows you to verify user input against your rules on the server, where you have full control over the validation logic. This kind of validation is essential for maintaining security and data integrity within an application.
