Smtp validating form
Sure there have been all kinds of whacky plug-ins over the years aimed at achieving this, but never a single standard that we could work towards.For a more detailed introduction to HTML5 form validation you can find some great articles linked under References below.Different browsers may mark the input box in some way (Firefox 4 Beta adds a red box-shadow by default), display a warning (Opera) or even prevent the form from being submitted if this field has no value.Hopefully these behaviours will converge in future releases.Would you also like to customize the appearance of your validation messages, or to style other parts of your forms?To get started, check out our Beginner’s Guide to CSS.The value, clicking 'down' with the input blank will result in a very large number.

If anyone wants to contribute a more thorough expression to test for valid email or url format, feel free to post it using the Feedback option above.. Since it is not possible to recurse when using a regular expression it is also not possible to create a truly accurate regex for doing email address validation.
