I really struggling with this. I need to force the user to write the first and last name, in only one textbox. I using AngularJS, and I want to validate text field using ng-pattern. The field should accept all characters, and require 2 words. This is input:
<input name="fistname_lastname" ng-model="fistname_lastname" ng-pattern='my_pattern' type="text">
I have the my pattern in the controller, like this:
$scope.my_pattern = /^\s*\w*\s*$/;
Is there another better way do it.
Yes, you can do it by directive too, but just for validating just text contains two characters or not ng-pattern would be better way to do.
Here your html would be using (.*?[a-zA-Z]){2,} this pattern.
HTML
<input type="text" ng-model="fistname_lastname" max-length="30"
ng-pattern="/^(.*?[a-zA-Z]){2,}$/" placeholder="add new todo here"/>
Update
If you want to stop your form from submitting,, then you need to no worry about it. Angular internally manages this for you. Whenever you mention ng-pattern against any form field, angular creates object for that field (field should have name and ng-model attribute), that object is responsible for the validity of particular field. As as ng-pattern regx doesn't gets satisfied, angular make that field as invalid, means it append ng-invalid-pattern & ng-invalid class. Resultant the form also gets invalid. and now if you can look at form object you will find that form gets invalid by using syntax form.$valid on html.
HTML
<form name="form" ng-submit="submit()">
<input type="text" ng-model="firstname_lastname" size="30" ng-pattern="/^(.*?[a-zA-Z]){2,}$/" placeholder="add new todo here"/>
<button type="submit">Submit</button>
</form>
Controller
$scope.submit = function(){
if($scope.form.$invalid) //here you can stop use from submitting for by checking validity
alert('Form is invalid'); //form is invalid
else
alert('Form is valid');//here you can do actual submit to server
}
Hopefully this could help you, Thanks.
ng-submit="submit()" method which will call when you submit the form then inside that method use if($scope.form.$valid) //submit the form usning ajax else alert("please fill required fields.");Thanks, for all your help. But what really worked was this regular expression.
\b([A-Z]{1}[a-z]{1,30}[- ]{0,1}|[A-Z]{1}[- \']{1}[A-Z]{0,1}
[a-z]{1,30}[- ]{0,1}|[a-z]{1,2}[ -\']{1}[A-Z]{1}[a-z]{1,30}){2,5}
/^(.*?[a-zA-Z]){2,}$/
