That means if your input requires a blue border, you give your container a blue border; Hosted Fields doesn't need to get involved.

Bear in mind that, in these articles, I’m not going to propose a new technique to replace existing server-side techniques, but rather just a proof of concept of session storage.

by Christopher Heng, Many websites, like, have a feedback form of some sort so that visitors can make comments to the webmasters.

If you have such a form on your site, I'm sure that from time to time, you would have received the results of your form with some essential field (like the email address or the visitor's name, or even the feedback itself) omitted. One way around it is to validate the essential fields with a simple Java Script.

It’s up to us to write data into the current session.

Session data comes in the form of key-value pairs, and the value of each key may contain only strings. This is a simple technique to convert a numerical string into a true number, ensuring that our calculation will be consistent. Objects may be stored in session storage by first turning them into JSON strings (with var cart = ; var json Str = JSON.stringify( cart ); session Item( "cart", json Str ); // now the cart is var cart Value = session Item( "cart" ); var cart Obj = JSON.parse( cart Value ); // original object of the W3C’s specification, then we’d be aware of the security risks of even a client-side technology such as Web storage.

Most often, the purpose of data validation is to ensure correct user input.

Remember that all values in session storage are strings, and our calculations must be between only numbers. The US Computer Emergency Readiness Team’s technical paper on website security“Every community organization, corporation, business, or government agency relies on an outward-facing website to provide information about themselves, announce an event, or sell a product or service.
