If you are a frequent internet user then of course you have filled many forms on websites by providing required information. These forms can be seen on various websites and applications of mobile such as social media or e-commerce. After providing exactly asked information such as product delivery address or your name and mail id for Facebook account, the form validates and enables you to use the services. In previous times,  if you entered any wrong or inappropriate information then the page reloads  and you have to enter the whole correct information again. Say thanks to form validation libraries that check the status of information before sending to the website.

For example, if you have entered an invalid mail id then the form validation libraries will alert you instantly by showing invalid info dialog in front of the mail address tab. It is a small yet very useful and time saving technology. These form validation libraries helps you to recheck the provided information and save your time wastage by entering whole information again. Java script is behind the way of checking the data before sending to web server. The form validation performs 2 types of functions:-

  • Basic validation
  • Data format validation
