Sadly, most beginning programmers fail to understand the truth about security: there is no such thing as "secure" or "insecure." The wise programmer knows that the real question is a site is.

Once any piece of data is stored in a database, in a text file, or on a Post-it note in your office, its security is compromised.

It's possible to validate any number of controls as well as the whole form.

Normally, in form and HTMLForm, data validation is bound to the submit button with the help of the click event handler: Per Item Validation with Predefined Rules If any record or field fails validation, it is marked with embedded red highlighting (true for both in-library and HTML5 validation).

The validation rules for standard HTML5 attributes are handled entirely by the browser using the HTML5 Constraint Validation API.

As such, this plugin isn't in control of things like what qualifies as a valid email address or URL.If you need to support these browsers, you must add a polyfill like Ryan Seddon's H5F.Scroll to and focus the first field with an error upon validation of the form.If you find you need more restrictive validations for these fields, you can use the attribute to further constrain what's acceptable.Be careful that you aren't too restrictive though, which might lead to false negatives and a poor user experience.The bottom Label property will be helpful for this purpose.
