Also, the ‘@’ must not be the first character of the email address, and the last dot must at least be one character after the ‘@’ sign. When using Textbox questions, often times you'll want to validate the data your respondents enter.Client side validations become very important when submitting data on a web page. We have an input box and it must accept only numbers, and it should not allow other characters as input.Here, in this post I'll show you an example on how to enter only numbers or allow only numbers with a decimal in a textbox using Java Script.

Email addresses, phone numbers, even IP addresses are easy to collect with the proper answer formatting that is built into Survey Gizmo.
Form validation is frequently done using client-side Java Script.
This approach is also possible in Web Logic Workshop.
The following example shows how to validate an entered email address.
An email address must contain at least a ‘@’ sign and a dot (.).
