Validation for email or phone number for same text field in angularjs

问题

I am working on registration form for my project in AngularJs. Users can register with his/her Email/Phone. I need to validate that particular text-box.

I have validations for both, with different text fields, with ng-pattern. But how can I validate for both in one text field?

I have updated my code, here:- enter code here http://plnkr.co/edit/mCVxHxl2DIvqOYtVapRN?p=preview

回答1:

Use /^([_a-z0-9]+(\.[_a-z0-9]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,5}))|(\d+$)$/

回答2:

You can use a pipe '|' to OR two regular expressions together:

/<email-pattern>|<phone-pattern>/

so your final regex would be:

/^([_a-z0-9]+(\.[_a-z0-9]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,5}))|\d+$/

You can use angular form validation and ng-pattern directive for input use ng-pattern="/^(?:\d{10}|\w+@\w+\.\w{2,3})$/"

Working Demo

var app = angular.module("MY_APP", []);
app.controller("MyCtrl", function($scope) {
  $scope.submitted = false;
  $scope.submit = function(userData){
  	console.log(userData)
  }
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="MY_APP">
  <div ng-controller="MyCtrl">
  <form name="userForm" novalidate ng-submit="userForm.$valid && submit(userData)">
              <div class="errorMsg" ng-show="submitted==true && userForm.$invalid">
                    <ul>
                        <li ng-show="submitted==true && userForm.emailphone.$error" class="errorMsg">
                            wrong format, It should be email or 10 digit mobile number
                        </li>
                    </ul>
                </div>
    <input type="text" name="emailphone" ng-model="userData.user" id="emailphone"  required
    ng-pattern="/^(?:\d{10}|\w+@\w+\.\w{2,3})$/" />
    <button type="submit" ng-click="submitted = true">Submit</button>
</form>
</div>
</div>

This code might work for you: Here is the ans of your question 
<script type="text/javascript">
            function validate(){
                var phoneNo = document.getElementById('txtEmailormob');
                var c=document.forms["myForm"]["email"].value;
                var atpos=c.indexOf("@");
                var dotpos=c.lastIndexOf(".");
                var errorMsg = document.getElementById("errorMsg");
                var successMsg = document.getElementById("successMsg");

                if(phoneNo.value==""||phoneNo.value==null){
                errorMsg.style.display="block";
                document.getElementById("errorMsg").innerHTML = "Please enter your Mobile No or Email  ";
                    return false;
                 }
                if ((phoneNo.value.length < 10 || phoneNo.value.length > 10) && (atpos<1 || dotpos<atpos+2 || dotpos+2>=c.length)) {
                errorMsg.style.display = "block";
                successMsg.style.display = "none";
                document.getElementById("errorMsg").innerHTML = "  Mobile No. is not valid, Please Enter 10 Digit Mobile No or Please Enter valid Email. ";
                return false;
            }
                successMsg.style.display = "block";
                document.getElementById("successMsg").innerHTML = " Success ";
                errorMsg.style.display = "none";
                return true;
                }
            </script>
