What is jQuery Unobtrusive Validation? 🤔
Have you ever heard of jQuery Validation plugin? 📜 It's a popular library that helps validate user input on web forms. But have you ever wondered what the "unobtrusive" version of jQuery Validation is all about? 🤔 In this blog post, we'll dive into the world of jQuery Unobtrusive Validation and see what sets it apart from its standard counterpart! 💫🚀
A Quick Refresher on jQuery Validation Plugin ✔
Before we jump into the unobtrusive stuff, let's do a quick recap on the standard jQuery Validation plugin. 📝 This plugin provides a powerful and flexible way to validate user input on forms in a web application. It allows you to define validation rules and messages, and it also provides various options for customization. 💪
Introducing jQuery Unobtrusive Validation 🌟
Now, let's introduce the star of our show - jQuery Unobtrusive Validation! This library was created by Microsoft and is included in the ASP.NET MVC framework. The term "unobtrusive" refers to the library's approach to validation - it aims to keep the validation logic separate from the HTML markup. 🚫🖋
Why go Unobtrusive? 🌈
The idea behind unobtrusive validation is to separate the concerns of validation and presentation. By keeping the validation logic separate from the HTML markup, we ensure a clean separation of concerns and improve the maintainability of our code. 🧹💪
How does it work? 🔧💡
In the standard jQuery Validation plugin, we define validation rules by adding attributes directly to the form elements in our HTML markup. For example, we might add the required attribute to a text input to make it a required field.
With jQuery Unobtrusive Validation, instead of adding attributes to the elements, we add data-* attributes that specify the validation rules. These data-* attributes are then parsed by the library to perform the validation. 🧪👩🔬
Here's an example:
<input type="text" name="email" data-val="true" data-val-required="The email field is required" data-val-email="Please enter a valid email address">In this example, the data-val attribute indicates that validation is enabled for this input, and the data-val-required and data-val-email attributes specify the corresponding validation messages. 💬📝
Benefits of jQuery Unobtrusive Validation 🌟
Separation of concerns: By keeping validation logic separate from markup, we improve code maintainability and make it easier to make changes in the future.
Ease of integration: If you're using ASP.NET MVC, unobtrusive validation is already built-in and ready to use with minimal configuration.
Flexibility: Unobtrusive validation works seamlessly with other jQuery plugins, allowing you to combine the power of multiple libraries in your web applications.
