Hi all,

I need to do the client side validations for my empty asp.net MVC 3 app...

What i know till now is,

"We can write the validations in the form of functions in javascript file and then we can call this function and js file along with CSS in _Layout.cshtml file."

Now my question is while searching in google, i found as "Unobtrusive JavaScrip".

I am not getting clear idea regarding this.

Can any one tell me exactly what it mean and in which way we can use it....

Thanks in advance....

Well, most of the answers to the questions being asked here can be found on Google. It would be hard to get an answer if you are, indeed not getting a clear idea even by googling the said term. :)

Unobtrusive JavaScript is a general approach to the use of JavaScript in web pages.
When you use unobtrusive validation, the validation rules are turned into HTML5 attributes. HTML5 attribute names can consist of only lowercase letters, numbers, and dashes.
