Is that what ngTrim is for in Angular?

Question

Angular

Hello.
I don't understand what ng-trim is for?
If it's stripping spaces at the end and beginning, then you can't get it to work.
If this is cleaning everything that does not fit the regular season, then it does not work either.

Answer 1

If set to false Angular will not automatically trim the input. This parameter is ignored for input[type=password] controls, which will never trim the input.
(default: true)
