angular.js - Angular Is there any good solution to repeated judgment expressions like this? ~

Question

Answer 1

It won’t have much impact if you write it like this now. If your judgment expression is too long, you can consider writing it as a function and calling the function directly

For example:

$scope.someFun(){
    return $scope.submitted && $scope.form.$invalid;
}


ng-disabled="someFun()"

Answer 2

getter defines a submitDisabled, and then performs rule determination internally.

get submitDisabled() {
  return submitted && form.$invalid
}
