QS:Preg validation

値チェック（正規表現を使う）(preg_validation)

説明

This option lets you specify a regular expression with which to validate all parts of a question.

If any question or sub-question value does not meet the validation requirements, the background color of the text entry field will be changed to red ^{(New in 1.92 )} so that users can easily see which parts of the question need to be corrected. Thus, you can do on-page validation and do not need to wait for the user to click submit in order to validate the question.

Valid values

• Any valid regular expression
