Hello Joaquín,
This is a nice thought, but I can disable it by turning off javascript
or using a browser that doesn't even support javascript. Javascript
is to be used for functional enhancements. It shouldn't be used as a
backstop for error handling or any other function that you need to count on
your application to do in order for things to work properly...unless
you state up-front that in order to use the application, javascript
at some specified version level (generally 1.2) *must* be enabled.
