Angular regex test not consistent ng-pattern validation on input

Question

I have a ng-pattern validation on my input

ng-pattern=\"/^(.+)$/g\"

This does not work the same everytime. And shows very weird behaviour.

Answer 1

You must remove the /g from the regex, see updated plunkr.

According to the docs:

Note: Avoid using the g flag on the RegExp, as it will cause each successive search to start at the index of the last search's match, thus not taking the whole input value into account.
