I'm creating a language quiz where users can write down their answers, like a translation for example. But I've noticed, when the answer requires punctuation, like a quotation mark, that some devices use a different style of punctuation and that will result in a wrong answer, because the punctuation used in the correct answer is just a bit different.
Here's the javascript I'm using to check answers:
<script>
var answers = {
q1: ["Auto's"]
};
function markAnswers(id) {
$(`#q${id}`).each(function () {
if ($.inArray(this.value, answers[this.id]) === -1) {
$(this).parent().append(`<br><span class='incorrect'>✗ Correct answer = ${answers[this.id]}</span>`);
} else {
$(this).parent().append("<br><span class='correct'>✓ Correct!</span>");
}
});
}
$("form").on("submit", function (e) {
e.preventDefault();
const id = e.target.id.replace("formId", "");
markAnswers(id);
$(`#submitId${id}`).each(function () {
this.setAttribute("disabled", true);
this.value = "Check answer";
});
});
</script>
As you can see, here I have an answer that requires a single quote ('), but apparently not all single quotes are equal.
I did find some code to replace specific punctuation and it's this: [^\w\s\']|_
But I'm not sure how to implement it and I would rather just accept the different punctuation. My only concerns are quotation marks and whitespace (as autofill on phones and tablets can create space).
Any suggestion on how to implement this is much appreciated. Thanks!
Edit:
Based on #Don't Panic's earlier versions of his code below (without .clean and .display) I want to make a few tweaks to it, but before I can, the code below always shows ✗ Correct answer = no matter if the answer is typed correctly or not. What could be wrong?
And about the tweaks. I've come to understand that Apple uses Smart Punctuation and this is a feature you can turn off. So I will ask my students to do that. Because I've tested it and without this feature toggled on, it will display a more straight/normal apostrophe and the answer will be accepted as correct. But since apostrophes and perhaps some other punctuation like a comma will be important, I want to add those to the existing line of code ^a-zA-Z\d. And I was thinking to at least ignore periods and extra spaces.
Thank you for all the help!
// Write out your answers without punctuation
var answers = {
q1: ["Autos"]
};
function markAnswers(id) {
$(`#q${id}`).each(function () {
// First, strip out any punctuation the user has entered
let userAnswer = this.value.replace(/[^a-zA-Z\d]/g,'');
// Now check if that "cleaned" value matches your answer
if ($.inArray(userAnswer, answers[this.id]) === -1) {
$(this).parent().append(`<br><span class='incorrect'>✗ Correct answer = ${answers[this.id]}</span>`);
} else {
$(this).parent().append("<br><span class='correct'>✓ Correct!</span>");
}
});
}
Take the user's input, strip out all punctuation, do the same to your answer, and compare the two. This way a user can use any punctuation they like, but it will just be stripped out and not part of the comparison.
This won't work if your questions are eg related to grammar, eg if you are testing when and where an apostrophe is correct, of course - in those cases the apostrophe is the answer!
The exact regular expression will depend on what has to be in your questions. Let's say you need all uppper- and lower-case letters and numbers:
$('button').on('click', function() {
markAnswers(1)
});
// Correct answers
var answers = {
"q1": "Auto's"
};
function markAnswers(id) {
$(`#q${id}`).each(function () {
// First, strip out any punctuation the user has entered
let userAnswer = this.value.replace(/[^a-zA-Z\d]/g,'');
// Strip any punctuation from the right answer
let correct = answers[this.id].replace(/[^a-zA-Z\d]/g,'');
// Now check if they match
if (userAnswer !== correct) {
$(this).parent().append(`<br><span class='incorrect'>✗ Correct answer = ${answers[this.id]}</span>`);
} else {
$(this).parent().append("<br><span class='correct'>✓ Correct!</span>");
}
});
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div>
What is the plural of <b>Auto</b>?
<input id='q1' type='text'>
<button>Check!</button>
</div>
To answer your new question - your code works fine for me.
I've added a button handler to actually run the check, but otherwise this is a copy-paste of your code.
If I type asdf, I get "✗ Correct answer = Autos", which is correct;
If I type autos, I get "✗ Correct answer = Autos", which is correct (lower case "a" instead of "A");
If I type Autos, I get "✓ Correct!", which is correct;
If I type "Auto's" (including those quotes), I get "✓ Correct!", which is correct;
$('button').on('click', function() {
markAnswers(1)
});
// Write out your answers without punctuation
var answers = {
q1: ["Autos"]
};
function markAnswers(id) {
$(`#q${id}`).each(function () {
// First, strip out any punctuation the user has entered
let userAnswer = this.value.replace(/[^a-zA-Z\d]/g,'');
// Now check if that "cleaned" value matches your answer
if ($.inArray(userAnswer, answers[this.id]) === -1) {
$(this).parent().append(`<br><span class='incorrect'>✗ Correct answer = ${answers[this.id]}</span>`);

Here is my regex:
var emailsRegex = /^[\W]*([\w+\-.%]+#[\w\-.]+\.[A-Za-z]{2,4}[\W]*;{1}[\W]*)*([\w+\-.%]+#[\w\-.]+\.[A-Za-z]{2,4})[\W]*$/;
Currently it allows fully qualified single emails and multiple emails separated by semicolon, example:
email1#hi.com
email1#hi.com; email2#hi.com
email1#hi.com; email2#hi.com; email3#hi.com
...are all valid.
I want this to stay the same, but also allow blank/empty inputs. My form is flagging $invalid with a blank input field, even though the required attribute is not specified on the input field.
I suspect this is because it is not passing the regex validation. Thanks!
Please do not use a regex to match an email. First of all your regex is wrong (it won't match emails like foo+bar#example.org which is perfectly valid given RFC822 and newer RFCs). You should better use a library like verifyjs or fogcreek's email checker to check that email.
Then all you have to do is to split your string around each emails using email_string.split(';') and apply the checker on each of them.
HTH
I ended up using string.split(;) and then passing through an improved RegEx which should account for 99% of email addresses in use today. And I'm doing it inside an Angular Directive.
It allows for empty inputs, multiple emails separated by ; which comply with the RFC for majority usage of email addresses.

The script below is suppose to insert a message using .insertAfter() if a user doesn't type in an # symbol within a field . This script also displays an error message if the user types in a value that matches a value from the invalidEmailAddresses array.
For some reason only the second part of this script executes.
If a user types in an # symbol they get a message but if the user types in an address similar to test#yahoo.com a message doesn't display. Not sure if i organized the code correctly.
$(document).ready(function(){
$("input[name='emailAddress']").blur(function(){
// Actual Email Validation function
var hasError = false;
var emailaddressVal = $("input[name='emailAddress']").val();
var invalidEmailAddresses =
['goddady.com', 'aol.com', 'yahoo.com', 'yahoo.fr'];
if ($.inArray(emailaddressVal,invalidEmailAddresses) > 0) {
$( "<span id='emailMessage'>The email provided is not from a business related domain. Please use an appropriate email address instead.</span>" ).insertAfter( "input[name='emailAddress']" );
} else {
$ ('#emailMessage').css('display','none');
}
if ($("input[name='emailAddress']").val().indexOf('#') > -1) {
$ ('#emailMessage').css('display','none');
}
else {
$( "<span id='emailMessage'>The email provided does not contain an # symbol</span>" ).insertAfter( "input[name='emailAddress']" );
}
if(hasError == true) { return false; }
});
});
This is working if you add the following code
$(document).ready(function() {
$("input[name='emailAddress']").blur(function() {
// Actual Email Validation function
$('#emailMessage').html("");
var hasError = false;
var emailaddressVal = $("input[name='emailAddress']").val().trim();
var invalidEmailAddresses = ['goddady.com', 'aol.com', 'yahoo.com', 'yahoo.fr'];
if (!isValidEmailAddres(emailaddressVal)) {
$("<span id='emailMessage'>The email provided does not contain an # symbol</span>").insertAfter("input[name='emailAddress']");
hasError = true;
} else {
debugger
emailaddressVal = emailaddressVal.split('#').slice(1)[0].trim();
if ($.inArray(emailaddressVal, invalidEmailAddresses) >= 0) {
$("<span id='emailMessage'>The email provided is not from a business related domain. Please use an appropriate email address instead.</span>").insertAfter("input[name='emailAddress']");
} else {
$('#emailMessage').css('display', 'none');
}
}
if (hasError == true) {
return false;
}
});
function isValidEmailAddres(emailID) {
var regexExp = new RegExp(/^((([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+(\.([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+)*)|((\x22)((((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(([\x01-\x08\x0b\x0c\x0e-\x1f\x7f]|\x21|[\x23-\x5b]|[\x5d-\x7e]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(\\([\x01-\x09\x0b\x0c\x0d-\x7f]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))))*(((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(\x22)))#((([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)+(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.?$/i);

The issue lies with this if conditional: if ($.inArray(emailaddressVal,invalidEmailAddresses) > 0).
Since the $.inArray() method returns the index of a string found, when a value of 0 is returned, it is actually found—but at the start of the string (position 0, because JS is zero-based). So, you should use !== -1 instead, i.e.: if ($.inArray(emailaddressVal,invalidEmailAddresses) !== -1).
However, this does not completely solve your issue — $.inArray() only compares string, it does not search for it. Therefore if your string contains the blacklisted email domains, but does not match exactly, it will return false. In this case, you should use regular expression instead. The strategy is simple: use .each() to loop through your array, and take the value, use it to construct an expression which we will test your email address that is provided against.
Also, since there is the possibility that the user-entered email address fails both tests, two <div> of identical IDs will appear. This is invalid HTML. Instead, try using a class instead.
p/s: I also recommend changing listening to .blur() to .change() instead. It is more robust :)
With all the points above considered, I have refactored your code a little:
Declare a global (but still within function scope) error array called hasError. It will be used to store all error messages you get, since we cannot be sure if there will be one, or more than one error.
We construct two tests:
To test if email matches against blacklist using the string.search(regexp) method. If there is a match, the value returned will exceed -1. We then push the relevant error message into hasError in an object
To test if email contains the # sign, we use your default logic (which works beautifully). If there is an error, we push, again, the relevant error message into hasError in an object
At the end, we evaluate hasError. If it is not empty, then we know there is an error somewhere, and loop through it. The error messages are accessible via the messages keyword :)
Without further ado, here's your code:
$(document).ready(function() {
$("input[name='emailAddress']").change(function() {
// Actual Email Validation function
var hasError = [],
emailaddressVal = $("input[name='emailAddress']").val(),
invalidEmailAddresses = ['godaddy.com', 'aol.com', 'yahoo.com', 'yahoo.fr'];
// Check against blacklist
$.each(invalidEmailAddresses, function(i, v) {
var pattern = new RegExp(v, 'i');
if (emailaddressVal.search(pattern) > -1) {
hasError.push({
'test': 'blacklist',
'message': 'The email provided is not from a business related domain. Please use an appropriate email address instead.'
});
}
});
// Check if there is an '#' character
if ($("input[name='emailAddress']").val().indexOf('#') === -1) {
hasError.push({
'test': '# sign',
'message': 'The email provided does not contain an # symbol'
});
}
console.log(hasError);
// Error handling
$('#error').remove();
if(hasError.length > 0) {
var $error = $('<div id="error"><ul></ul></div>');
$.each(hasError, function(i,v) {
$error.find('ul').append('<li>'+v.message+'</li>');
});
$error.insertAfter("input[name='emailAddress']");
}
});
});

I have client side email validation script Javascript+RegEx, it works fine, but I want to exclude certain domains while validating, namely all Apple domains since they do not work (emails sent to these addresses are deleted without any notice): #apple.com, #me.com, #icloud.com, #mac.com.
I found appropriate questions here, but still they are not the same I am asking for help.
Please, help to implement this
Can it be done via RegEx modification, or I have to use loop and search substrings (#apple.com, #me.com, #icloud.com, #mac.com) after the main email validation is done?
function verifyMe(){
var msg='';
var email=document.getElementById('email').value;
if(!(/^\w+([\.-]?\w+)*#\w+([\.-]?\w+)*(\.\w{2,3})+$/.test(email)) ||
document.getElementById('email').value=='')
{
msg+='- Invalid Email Address: '+email+'\n\n';
document.getElementById('Eemail').style.color='#ffffff';
}
else
document.getElementById('Eemail').style.color='#bbb'
if(msg!='')
return false;
else
{
search_code(); //it's ok go ahead
return true;
}
}
Both approaches would work.
For the regex one, just insert the following part after the # in the regex (negative lookahead):
(?!(?:apple|me|icloud|mac)\.com$)
But a better regex overall would be:
^\w+[-\.\w]*#(?!(?:apple|me|icloud|mac)\.com$)\w+[-\.\w]*?\.\w{2,4}$
For the other approach, the following should work:
function isValidMailAddress(email) {
var match = /^\w+[-\.\w]*#(\w+[-\.\w]*?\.\w{2,4})$/.exec(email);
if (!match)
return false;
var forbiddenDomains = ["apple.com", "me.com", "icloud.com", "mac.com"];
if (forbiddenDomains.indexOf(match[1].toLowerCase()) >= 0)
return false;
return true;
}
It's up to you to decide which approach you feel most comfortable with.
You can use jQuery.inArray() for checking email with a specific domain name.
var email ="abc#xyz.edu.au"
var str = email.split('#').slice(1);
var allowedDomains = ['xyz.edu.au','abc.edu.au'];
if($.inArray(str[0], allowedDomains) === -1) {
alert('email is allowed.');
}
else{
alert('email not allowed.');
}
I updated #Lucas answer to match any type of country domain (apple.com, apple.de etc.).
Moreover it should be more robust because its closer to W3C standard: https://emailregex.com/
^[a-zA-Z0-9.!#$%&’*+/=?^_`{|}~-]+#(?!(?:yahoo|gmail|icloud|web|googlemail|aol|zoho|protonmail|outlook|hotmail|gmx|mail)[a-zA-Z0-9.!#$%&’*+/=?^_`{|}~-]{1,10}$)[a-zA-Z0-9-]+(?:\.[a-zA-Z0-9-]+)*$
I've made a function (in JavaScript) that takes an URL from either YouTube or Vimeo. It figures out the provider and ID for that particular video (demo: http://jsfiddle.net/csjwf/).
function parseVideoURL(url) {
var provider = url.match(/http:\/\/(:?www.)?(\w*)/)[2],
id;
if(provider == "youtube") {
id = url.match(/http:\/\/(?:www.)?(\w*).com\/.*v=(\w*)/)[2];
} else if (provider == "vimeo") {
id = url.match(/http:\/\/(?:www.)?(\w*).com\/(\d*)/)[2];
} else {
throw new Error("parseVideoURL() takes a YouTube or Vimeo URL");
}
return {
provider : provider,
id : id
}
}
It works, however as a regex Novice, I'm looking for ways to improve it. The input I'm dealing with, typically looks like this:
http://vimeo.com/(id)
http://youtube.com/watch?v=(id)&blahblahblah.....
1) Right now I'm doing three separate matches, would it make sense to try and do everything in one single expression? If so, how?
2) Could the existing matches be more concise? Are they unnecessarily complex? or perhaps insufficient?
3) Are there any YouTube or Vimeo URL's that would fail being parsed? I've tried quite a few and so far it seems to work pretty well.
To summarize: I'm simply looking for ways improve the above function. Any advice is greatly appreciated.
Here's my attempt at the regex, which covers most updated cases:
function parseVideo(url) {
// - Supported YouTube URL formats:
// - http://www.youtube.com/watch?v=My2FRPA3Gf8
// - http://youtu.be/My2FRPA3Gf8
// - https://youtube.googleapis.com/v/My2FRPA3Gf8
// - Supported Vimeo URL formats:
// - http://vimeo.com/25451551
// - http://player.vimeo.com/video/25451551
// - Also supports relative URLs:
// - //player.vimeo.com/video/25451551
url.match(/(https?\/\/)(player.|www.)?(vimeo\.com|youtu(be\.com|\.be|be\.googleapis\.com))\/(video\/|embed\/|watch\?v=|v\/)?([A-Za-z0-9._%-]*)(\&\S+)?/);
var type = null;
if (RegExp.$3.indexOf('youtu') > -1) {
type = 'youtube';
} else if (RegExp.$3.indexOf('vimeo') > -1) {
type = 'vimeo';
}
return {
type: type,
id: RegExp.$6
};
}
Regex is wonderfully terse but can quickly get complicated.
http://jsfiddle.net/8nagx2sk/
function parseYouTube(str) {
// link : //youtube.com/watch?v=Bo_deCOd1HU
// share : //youtu.be/Bo_deCOd1HU
// embed : //youtube.com/embed/Bo_deCOd1HU
var re = /\/\/(?:www\.)?youtu(?:\.be|be\.com)\/(?:watch\?v=|embed\/)?([a-z0-9_\-]+)/i;
var matches = re.exec(str);
return matches && matches[1];
}
function parseVimeo(str) {
// embed & link: http://vimeo.com/86164897
var re = /\/\/(?:www\.)?vimeo.com\/([0-9a-z\-_]+)/i;
var matches = re.exec(str);
return matches && matches[1];
}
Sometimes simple code is nicer to your fellow developers.
https://jsfiddle.net/vkg02mhp/1/
// protocol and www nuetral
function getVideoId(str, prefixes) {
const cleaned = str.replace(/^(https?:)?\/\/(www\.)?/, '');
for(const prefix of prefixes) {
if (cleaned.startsWith(prefix))
return cleaned.substr(prefix.length)
}
return undefined;
}
function getYouTubeId(url) {
return getVideoId(url, [
'youtube.com/watch?v=',
'youtu.be/',
'youtube.com/embed/'
]);
}
function getVimeoId(url) {
return getVideoId(url, [
'vimeo.com/'
]);
}
Which do you prefer to update?
I am not sure about your question 3), but provided that your induction on the url forms is correct, the regexes can be combined into one as follows:
/http:\/\/(?:www.)?(?:(vimeo).com\/(.*)|(youtube).com\/watch\?v=(.*?)&)/
You will get the match under different positions (1st and 2nd matches if vimeo, 3rd and 4th matches if youtube), so you just need to handle that.
Or, if you are quite sure that vimeo's id only includes numbers, then you can do:
/http:\/\/(?:www.)?(vimeo|youtube).com\/(?:watch\?v=)?(.*?)(?:\z|&)/
and the provider and the id will apprear under 1st and 2nd match, respcetively.
Here is my regex
http://jsfiddle.net/csjwf/1/
For Vimeo, Don't rely on Regex as Vimeo tends to change/update their URL pattern every now and then. As of October 2nd, 2017, there are in total of six URL schemes Vimeo supports.
https://vimeo.com/*
https://vimeo.com/*/*/video/*
https://vimeo.com/album/*/video/*
https://vimeo.com/channels/*/*
https://vimeo.com/groups/*/videos/*
https://vimeo.com/ondemand/*/*
Instead, use their API to validate vimeo URLs. Here is this oEmbed (doc) API which takes an URL, checks its validity and return a object with bunch of video information(check out the dev page). Although not intended but we can easily use this to validate whether a given URL is from Vimeo or not.
So, with ajax it would look like this,
var VIMEO_BASE_URL = "https://vimeo.com/api/oembed.json?url=";
var yourTestUrl = "https://vimeo.com/23374724";
$.ajax({
url: VIMEO_BASE_URL + yourTestUrl,
type: 'GET',
success: function(data) {
if (data != null && data.video_id > 0)
// Valid Vimeo url
else
// not a valid Vimeo url
},
error: function(data) {
// not a valid Vimeo url
}
});
about sawa's answer :
a little update on the second regex :
/http:\/\/(?:www\.)?(vimeo|youtube)\.com\/(?:watch\?v=)?(.*?)(?:\z|$|&)/
(escaping the dots prevents from matching url of type www_vimeo_com/… and $ added…)
here is the same idea for matching the embed urls :
/http:\/\/(?:www\.|player\.)?(vimeo|youtube)\.com\/(?:embed\/|video\/)?(.*?)(?:\z|$|\?)/
FWIW, I just used the following to validate and parse both YouTube and Vimeo URLs in an app. I'm sure you could add parentheses to parse out the specific things you're looking for...
/^(?:https?:\/\/)?(?:www\.)?(?:youtu\.be\/|youtube\.com\/(?:embed\/|v\/|watch\?v=|watch\?.+&v=))((\w|-){11})(?:\S+)?$|^(https?:\/\/)?(www.)?(player.)?vimeo.com\/([a-z]*\/)*([0-9]{6,11})[?]?.*$/
^^ This is just a combination of 2 separate expressions using | (or) to join them. Here are the original 2 expressions separately:
/^(?:https?:\/\/)?(?:www\.)?(?:youtu\.be\/|youtube\.com\/(?:embed\/|v\/|watch\?v=|watch\?.+&v=))((\w|-){11})(?:\S+)?$/
/^(https?:\/\/)?(www.)?(player.)?vimeo.com\/([a-z]*\/)*([0-9]{6,11})[?]?.*$/
I'm no expert, but it seems to work according to Rubular. Hopefully this helps someone out in the future.
3) Your regex does not match https url's. I haven't tested it, but I guess the "http://" part would become "http(s)?://". Note that this would change the matching positions of the provider and id.
Just in case here is a php version
/*

I had a task to enable adding a dropbox videos. So the same input should take href, check it and transform to the playable link which I can then insert in .
const getPlayableUrl = (url) => {
// Check youtube and vimeo
let firstCheck = url.match(/(http:|https:|)\/\/(player.|www.)?(vimeo\.com|youtu(be\.com|\.be|be\.googleapis\.com))\/(video\/|embed\/|watch\?v=|v\/)?([A-Za-z0-9._%-]*)(\&\S+)?/);
if (firstCheck) {
if (RegExp.$3.indexOf('youtu') > -1) {
return "//www.youtube.com/embed/" + RegExp.$6;
} else if (RegExp.$3.indexOf('vimeo') > -1) {
return 'https://player.vimeo.com/video/' + RegExp.$6
}
} else {
// Check dropbox
let candidate = ''
if (url.indexOf('.mp4') !== -1) {
candidate = url.slice(0, url.indexOf('.mp4') + 4)
} else if (url.indexOf('.m4v') !== -1) {
candidate = url.slice(0, url.indexOf('.m4v') + 4)
} else if (url.indexOf('.webm') !== -1) {
candidate = url.slice(0, url.indexOf('.webm') + 5)
}
let secondCheck = candidate.match(/(http:|https:|)\/\/(player.|www.)?(dropbox\.com)\/(s\/|embed\/|watch\?v=|v\/)?([A-Za-z0-9._%-]*\/)?(.*)/);
if (secondCheck) {
return 'https://dropbox.com/' + RegExp.$4 + RegExp.$5 + RegExp.$6 + '?raw=1'
} else {
throw Error("Not supported video resource.");
}
}
}
I based myself the previous answers but I needed more out the regex.
Maybe it worked in 2011 but in 2019 the syntax has changed a bit. So this is a refresh.
The regex will allow us to detect weather the url is Youtube or Vimeo.
I've added Capture group to easily retrieve the videoID.
If ran with Case insensitive setting please remove the (?i).
(?:(?i)(?:https:|http:)?\/\/)?(?:(?i)(?:www\.youtube\.com\/(?:embed\/|watch\?v=)|youtu\.be\/|youtube\.googleapis\.com\/v\/)(?<YoutubeID>[a-z0-9-_]{11,12})|(?:vimeo\.com\/|player\.vimeo\.com\/video\/)(?<VimeoID>[0-9]+))

Use this Regex devs:This works like Makhan(react js,Javascript)
^(http\:\/\/|https\:\/\/)?((www\.)?(vimeo\.com\/)([0-9]+)$)|((www\.youtube\.com|youtu\.be)\/.+$)
