Angularjs how to do IF CONTAINS in $scope?

Question

I want to know if it's possible to know if there are a char in a $scope for example something like this but in angularJs

$scope.test = "Hi, How Are You?";
if($scope.test.Contains("?")) {
  return true
} else {
  return false
}

Answer 1

You can just replace Contains with match:

if($scope.test.match("?")) {
    return true
} else {
    return false
}

And you can even further optimize this whole code block to just:

return !!$scope.test.match("?");

Answer 2

Well you can do it like this..

var string = "hello";
alert(string.indexOf("llo") != -1);

so in regards to your code above..

$scope.test= "HI How Are You ?";
alert($scope.test.indexOf("How") != -1); // return true;

Answer 3

Try the codes below:

ng-attr-target="{{(p.link.indexOf('https://')!=-1) ? '_blank' : _self}}"
