Basically you can create a regex to fulfil your needs and then assign that pattern to your input field.
基本上，您可以创建一个正则表达式来满足您的需求，然后将该模式分配给您的输入字段。
Or for a more direct approach:
或者更直接的方法：
<input type="number" require ng-pattern="<your regex here>">
More info @ angular docs hereand here (built-in validators)

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.
您也可以使用 ng-pattern ，[7-9] = > 手机号码必须以 7 或 8 或 9 开头，[0-9] = 手机号码接受数字，{9} 手机号码应为 10 位数字。
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>

You can also use ng-patternand 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.
你也可以使用ng-pattern，我觉得这将是一个最佳实践。同样尝试使用ng-message. 请查看以下 html 上的 ng-pattern 属性。代码片段是部分的，但希望你能理解。
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>

<input type="number"
placeholder = "Enter your phonenumber"
class = "formcontroll"
name = "numbers"
ng-minlength = "10"

<p ng-show = "numberForm.numbers.$error.required ||
numberForm.numbers.$error.number">
Valid phone number is required</p>

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.
我发现一个更干净、更专业的外观是使用 AngularUI Mask。实施起来非常简单，也可以为其他输入定制掩码。然后，您只需要一个简单的必需验证即可。

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.
使用 ng-pattern，在这个例子中，你可以验证一个包含 10 个数字的简单模式，当模式不匹配时，显示消息并禁用按钮。
<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.$valid" ng-click="callDigitaliza()">Buscar</button>
Also you can use another complex patern like
你也可以使用另一个复杂的模式
^+?\d{1,3}?[- .]?(?(?:\d{2,3}))?[- .]?\d\d\d[- .]?\d\d\d\d$
^+?\d{1,3}?[- .]?(?(?:\d{2,3}))?[- .]?\d\d\d[- .]?\d\ d\d\d$
, for more complex phone numbers
, 对于更复杂的电话号码

<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.
这里“userForm”是我的表单名称。
