Regex to validate that first letter of every word is capital in angular js

Question

I am using angularjs. I want to use validation for my name field. I am a beginner in regex expressions. I want that the first letter of every word should be capital. For E.g Naveen Kumar should be valid and Naveen kumar is invalid.

I am using ng-pattern to validate the name field. What regex expression should i use? Appreciate your help.

I tried to use (\s|^[A-Z])([a-z0-9-_]+).....But it is not working the way i want — vjangra, Apr 27 '15 at 11:19
Testing this is not always a good idea, several names with particles may not be valid: "de la Porte", "de la Rue". In my opinion, you should only test your field for allowed characters and if needed, format it before recording it. — Casimir et Hippolyte, Apr 27 '15 at 11:23

You can use this regex with ng-pattern:

ng-pattern="/^\b[A-Z][a-z]*(\s*\b[A-Z][a-z]*\b)*$/"

Demo

This regex will match only entries that have words (that do not contain digits or underscore) in title case only. Thus, Avinash Raj1 or Avinash_Raj Raj will fail the validation.

Example code:

<label>Single word:
    <input type="text" name="input" ng-model="example.text"
           ng-pattern="/^\b[A-Z][a-z]*(\s*\b[A-Z][a-z]*\b)*$/" required ng-trim="false">
</label>

You can use

^\b(?:[A-Z]\w+\b(?:\s*)?)+$

How about ^(\b[A-Z]\w*\s*)+$? See https://regex101.com/r/qP5xG5/1
