Form validation technique

Featured Replies

Good evening.

 

What is the most common technique to display an alert symbol next to an input field if the function recognises an incorrect entry on blur in javascript?

 

Do you insert an image or use CSS to display a div with a background image for e.g?

 

Thanks.

Lee.

Thanks very much for the reply but I was hoping for an example using native Javascript rather than jquery. The validation part isn't an issue it's just that I am trying to find the most efficient solution to display an image / symbol at the end of a field if that particular field entry is invalid.

 

The reason why I say not jQuery as I know this makes life easier is that this is an exercise I need to finish coding in javascript and CSS.

 

Thanks again.

Lee.
