For Internet users, form filling on many websites and mobile applications has become a common exercise to provide information, like email ID, name, product delivery address, etc, in order to use the services. After putting the required information, the form validates the information and allows you to use the services. However, form validation often frustrated many Internet users in the past as any wrong or incomplete information resulted in the page reload, forcing them to enter the whole correct information again.
#1. jQuery Validation Plugin
jQuery Validation plugin makes it possible for web developers to address the most important functions and the issues pertinent to form validation. jQuery Validation plugin includes important contents, like errors container, file uploads, dynamics forms, etc. However, as nothing is perfect in this world, jQuery Validation Plugin also has a disadvantage, and that is its jQuery dependency. The plugin has got excellent documentation, which is being used by many developers world over. English is the main language for default error messages, though translation option is available for as many as 37 languages.
Unlike many other validation libraries that are very tightly coupled to a language or framework, Validate.js provides a cross framework and cross language way of validating data. Besides, the library is free of any required external dependencies and offers easy documentation.
Verify.js, another MIT licensed form validation library, is fully customizable, easily extendable, unobtrusive, and includes grouped validations as well as asynchronous validations. However, before choosing it as a form validation tool, give a thought over its documentation which is currently in progress. There is a note on the top of its documentation, saying, “As this library and corresponding documentation is a work in progress, this API is subject to change.”
The goals behind GValidator development are as follows:
- A user-friendly experience
- Code flexibility and extensibility
- A reusable and lightweight library
- Promote adoption via ease of use
- Cross browser compatibility
- Semantically clean code
- Standards compliant code
