How to get use ng-pattern
I have a simple text input in which I only want to allow floats and ints (watch out: jade)
input.form-control(type="text", ng-model='usd', ng-pattern="nums",ng-change='convert_to_btc()', placeholder="USD")
However it doesn't work, I can always insert any character in the input (do I need to do more in order to display something? e.g. a red border if it's incorrrect? or should then just those characters not even be able to be entered?) The pattern is a regex and thus not a string, so that should be fine???
Here's the controller:
app.controller("AppCtrl", function AppCtrl($scope, $http, $interval ) {
//lots of other stuff
$scope.nums = /^\-?\d+((\.|\,)\d+)?$/; //note no string, it's a regex
}
This is the generated HTML. Could this be the problem? The generated HTML actually has a string, not a regex!?
<input type="text" ng-model="usd" ng-pattern="/^\-?\d+((\.|\,)\d+)?$/" ng-change="convert_to_btc()" placeholder="USD" class="form-control ng-dirty ng-valid-parse ng-touched ng-invalid ng-invalid-pattern">
