Ng-pattern must not match the given pattern

Question

In ng-patternwe have the opportunity to indicate that the field should match a specific template.

How can we indicate that it should NOT match the specified pattern?

Example

<input type="text" ng-pattern="/[*|\":<>[\]{}`()';@&$]/" />

Here I do NOT want the field to match the pattern. On the contrary, I want to show an error if the pattern matches.

Answer 1

To check if a string contains any substring, you can use string binding with a string:

/^(?!.*[*|\x22:<>[\]{}`()';@&$])/

Watch the demo

AngularJS , RegExp ( ), ( , ).

, ^(?:(?![*|\x22:<>\[\]{}`()';@&$]).)*$ (. demo), , .

, \x22 ng-pattern.

Answer 2

((?!pattern)), :

ng-pattern="/(?![*|\":<>[\]{}`()';@&$])/"
