我正在为我在 AngularJs 中的项目填写注册表单。用户可以使用他/她的电子邮件/电话进行注册。我需要验证那个特定的文本框。
我对两者都有验证，使用不同的文本字段，使用 ng-pattern。但是如何在一个文本字段中验证两者？
我已经更新了我的代码，在这里：- enter code here

/^[_a-z0-9]+(\.[_a-z0-9]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,5})$|^\d+$/
标签： javascript html angularjs validation angularjs-directive
这里是电子邮件或电话号码的正则表达式，请看一下，希望对您有所帮助。
谢谢
^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})|(^[0-9]{10})+$
这也是一个例子。

function validate(){
var value = $("#email_phone").val();
var regex = new RegExp('^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})|(^[0-9]{10})+$');
if(value){
if(!regex.test(value)){
$("#error").text("Please enter valid email address or phone number.")
}else{
$("#error").text('')
}
}else{
$("#error").text('This field is required.')
}

简单代码
像验证一样完成工作：amazon、Facebook、uber.etc 使用单一输入的电子邮件或电话号码...
试试它的工作原理......
<script>
$(document).ready(function () {
$("#cuntryCode").hide();
$("#useridInput").on('input', function () {
var len = $("#useridInput").val().length;
if (len >= 2) {
var VAL = this.value;
var intRegex = /^[1-9][0-9]*([.][0-9]{2}|)$/;
if (!intRegex.test(VAL)) {
$('#error-caption').html('Invalid email. Please check spelling.');
$('#error-caption').css('color', 'red');
$("#cuntryCode").hide();
} else {
if(len < 10){
$('#error-caption').html('Invalid mobile number. Please try again.');
$('#error-caption').css('color', 'red');
$("#cuntryCode").show();
}else{
$('#error-caption').html('Invalid mobile number. length must be 10 digit.');
$('#error-caption').css('color', 'red');
}
}
}else{
$("#cuntryCode").hide();
$('#error-caption').html('');
}
});
});
</script>
<form class="push--top-small forward" method="POST" data-reactid="15">
<h4 id="input-title" data-reactid="16">Welcome back
</h4>
<label class="label" id="input-label" for="useridInput" data-reactid="17">Sign in with your email address or mobile number.
</label>
<div style="margin-bottom:24px;" data-reactid="18">
<div >
<div id="cuntryCode" class="_style_4kEO6r" style="float: left; height: 44px; line-height: 44px;">
<div tabindex="0" > +241
</div>
</div>
<div style="display:flex;">
<input id="useridInput" autocorrect="off" autocapitalize="off" name="textInputValue" class="text-input" placeholder="Email or mobile number" aria-required="true" aria-invalid="false" aria-describedby="error-caption input-title">
</div>
</div>
<div id="error-caption">
</div>
</div>
<button class="btn btn--arrow btn--full" data-reactid="24">
<span class="push-small--right" data-reactid="25">Next
</span>
</button>
</form>

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>
【讨论】：
您可以使用角度表单验证和 ng-pattern 指令进行输入使用ng-pattern="/^(?:\d{10}|\w+@\w+\.\w{2,3})$/"
var app = angular.module("MY_APP", []);
app.controller("MyCtrl", function($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>

sanat.gupta@gmail.com，但是从您的函数中收到了错误的电子邮件。
使用/^([_a-z0-9]+(\.[_a-z0-9]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,5}))|(\d+$)$/
【讨论】：
您可以使用管道“|”将两个正则表达式组合在一起：
/<email-pattern>|<phone-pattern>/
所以你的最终正则表达式是：
/^([_a-z0-9]+(\.[_a-z0-9]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,5}))|\d+$/
