Unobtrusive JavaScript in MVC 3

Unobtrusive JavaScript is a general term that conveys a general set of guidelines or margins to the term REST.

REST is nothing but the Representational State Transfer.

We can explain Unobtrusive JavaScript as- it is not your particular JavaScript code that you generally use in your markup page.

Example

In spite of using event attributes like

• 'onbuttonclick'

• 'onpageload'

• 'onsubmit'

• 'onclick'

• 'mouseover'

Etc.

Unobtrusive JavaScript, attaches element directly by their ID or class, in the presence of the other attributes.
