Answer 1

Try this:

<form class="form-horizontal" role="form" method="post" name="registration" novalidate>
    <div class="form-group" ng-class="{'has-error': registration.phone.$error.number}">
        <label for="inputPhone" class="col-sm-3 control-label">Phone :</label>
        <div class="col-sm-9">
            <input type="number" 
                   class="form-control" 
                   ng-minlength="10" 
                   ng-maxlength="10"  
                   id="inputPhone" 
                   name="phone" 
                   placeholder="Phone" 
                   ng-model="user.phone"
                   ng-required="true">
            <span class="help-block" 
                  ng-show="registration.phone.$error.required || 
                           registration.phone.$error.number">
                           Valid phone number is required
            </span>
            <span class="help-block" 
                  ng-show="((registration.phone.$error.minlength ||
                           registration.phone.$error.maxlength) && 
                           registration.phone.$dirty) ">
                           phone number should be 10 digits
            </span>

You can also use ng-pattern and I feel that will be a best practice. Similarly try to use ng-message. Please look the ng-pattern attribute on the following html. The code snippet is partial but hope you understand it.

angular.module('myApp', ['ngMessages']);
angular.module("myApp.controllers",[]).controller("registerCtrl", function($scope, Client) {
  $scope.ph_numbr = /^(\+?(\d{1}|\d{2}|\d{3})[- ]?)?\d{3}[- ]?\d{3}[- ]?\d{4}$/;
});

<form class="form-horizontal" role="form" method="post" name="registration" novalidate>
  <div class="form-group" ng-class="{ 'has-error' : (registration.phone.$invalid || registration.phone.$pristine)}">
    <label for="inputPhone" class="col-sm-3 control-label">Phone :</label>
    <div class="col-sm-9">
      <input type="number" class="form-control" ng-pattern="ph_numbr"  id="inputPhone" name="phone" placeholder="Phone" ng-model="user.phone" ng-required="true">
      <div class="help-block" ng-messages="registration.phone.$error">
        <p ng-message="required">Phone number is required.</p>
        <p ng-message="pattern">Phone number is invalid.</p>
      </div>
    </div>
  </div>
</form>

An even cleaner and more professional look I have found is to use AngularUI Mask. Very simple to implement and the mask can be customized for other inputs as well. Then a simple required validation is all you need.

You can also use ng-pattern ,[7-9] = > mobile number must start with 7 or 8 or 9 ,[0-9] = mobile number accepts digits ,{9} mobile number should be 10 digits.

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

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.5/angular.min.js"></script>
<div ng-app ng-controller="form">
<form name="myForm" ng-submit="onSubmit()">
    <input type="number" ng-model="mobile_number" name="mobile_number" ng-pattern="/^[7-9][0-9]{9}$/" required>
    <span ng-show="myForm.mobile_number.$error.pattern">Please enter valid number!</span>
    <input type="submit" value="submit"/>
</form>
</div>

Answer 5

<div ng-class="{'has-error': userForm.mobileno.$error.pattern ,'has-success': userForm.mobileno.$valid}">

              <input type="text" name="mobileno" ng-model="mobileno" ng-pattern="/^[7-9][0-9]{9}$/"  required>

Here "userForm" is my form name.

Use ng-pattern, in this example you can validate a simple patern with 10 numbers, when the patern is not matched ,the message is show and the button is disabled.

 <form  name="phoneNumber">

        <label for="numCell" class="text-strong">Phone number</label>

        <input id="numCell" type="text" name="inputCelular"  ng-model="phoneNumber" 
            class="form-control" required  ng-pattern="/^[0-9]{10,10}$/"></input>
        <div class="alert-warning" ng-show="phoneNumber.inputCelular.$error.pattern">
            <p> write a phone number</p>
        </div>

    <button id="button"  class="btn btn-success" click-once ng-disabled="!phoneNumber.$valid" ng-click="callDigitaliza()">Buscar</button>

Also you can use another complex patern like

^+?\d{1,3}?[- .]?(?(?:\d{2,3}))?[- .]?\d\d\d[- .]?\d\d\d\d$

, for more complex phone numbers
