how to include qutoes + double quotes in ng-regex?

Question

I have phonegap application developed in android studio.

I have an input field that has to allow abc characters, quotes and double quotes.
wanted html code:

 <input placeholder="last name" type="text" ng-model="currentUser.LastName"
                       ng-pattern='/^([A-Za-z\"\' ]){1,45}$/'
                       required
                       class="form-control"/>

but I have a problem - the quotes in the regex close the whole regex.
what I can do:

ng-pattern='/^([A-Za-z\" ]){1,45}$/'

or

ng-pattern="/^([A-Za-z\' ]){1,45}$/"

but I cant find way to include quotes marks and double quotes, too.

I tried it:

in scope:

$scope.regex=/^([A-Za-z\"\' ]){1,45}$/;

in html page:

<input placeholder="last name" type="text" ng-model="currentUser.LastName" name="userLastName1"
                       ng-pattern='{{regex}}'
                       required
                       class="form-control"/>

it did not work, too (my editor is android studio, maybe other editors are better?).

is there any way to include both quotes and double quotes in one regex?

Answer 1

You can use hex values for those entities, \\x22 for " and \\x27 for ' :

$scope.regex= "/^[A-Za-z\x22\x27 ]{1,45}$/";

And you need no outer parentheses.

You can test it here .

Or here is a snippet showing it works in an ng-pattern attribute:

 function formCtrl($scope){ $scope.onSubmit = function(){ alert("form submitted"); } } 

 <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script> <div ng-app ng-controller="formCtrl"> <form name="myForm" ng-submit="onSubmit()"> <input type="text" name="field" ng-model="formCtrl" ng-pattern="/^[A-Za-z\\x22\\x27 ]{1,45}$/" required placeholder="last name"> <span ng-show="myForm.field.$error.pattern">Not valid!</span> <span ng-show="myForm.field.$error.required">This field is required!</span> <input type="submit" value="submit"/> </form> </div>
