I am new to HTML5...
Here i am having some problem with email pattern attribute...
1)if i am giving the input like user#gmail.com... in email field..
2)it's not accepting value and showing "Pattern not matched"..
Help me to fix this....
Here is the snippet of Html
<form name='f1' method="POST" action="" >
<div id="fp">
<span style="margin-left:-50px">Email:</span>
<span><input class="input" type="email" name="Email" placeholder="Enter mailID" required pattern="^[A-Z0-9._%+-]+#[A-Z0-9.-]+\.[A-Z]{2,4}$" ></span><br>
<input type="submit" name="submit" value="submit">
</div>
</form>
Any suggestions are acceptable....
this should be correct pattern
[^#]+#[^#]+\.[a-zA-Z]{2,6}
yes you forgot to consider lower case.
you can refer this document for more details

The accepted answer won't validate marian#iflove.technology
In this case not to miss out all those new domain names emails like http://www.iflove.technology/ you could use:
[^#]+#[^#]+\.[a-zA-Z]{2,}
Used with input type email it looks like this:
<input type="email" pattern="[^#]+#[^#]+\.[a-zA-Z]{2,}">
You need to account for lower cases too. Or make it case insensitive. But in reality you should just use:
^.+#.+$
And send a confirmation e-mail to the address that they should follow because e-mail addresses are reasonably complicated and you'll end up blocking stuff you don't intend to with a regex and it doesn't stop someone putting in a fake e-mail address anyway.
It is very difficult to validate Email correctly simply using HTML5 attribute "pattern". If you do not use a "pattern" someone# will be processed. which is NOT valid email.
Using pattern="[a-zA-Z]{3,}#[a-zA-Z]{3,}[.]{1}[a-zA-Z]{2,}[.]{1}[a-zA-Z]{2,}" will require the format to be someone#email.com
Simply remove the pattern attribute. The type="email" is enough.
I'm using this pattern right now, seems to work just fine:
[a-zA-Z0-9._\-]+#[a-zA-Z0-9.\-]+\.[a-zA-Z]{2,4}
My solution to override html5 validation type='email'. I run this code after DOM loaded
$(document).ready(function(){
$('input[type=email]').attr('pattern', "^([\\w]+[\\.]{0,1})+#([\\w-]+\\.)+[\\w]{2,4}$").attr('type', 'text').attr('title', 'Please enter an email address')
})

How do I tell my input to validate email inputs with the tld?
I don't want to accept email addresses in the form a#b.
I am aware I can specify a regex pattern to assert this behaviour, but this feels like a hacky approach. Is there a native attribute I can use to force the input element to validate the email address, including tld?
<form>
<input type="email" required="required" pattern="^[^#\s]+#([^#\s]+\.)+[^#\s]+$" value="a#b" />
<input type="submit"/>
</form>
There isn't a native attribute to validate the TLD. You can use the pattern attribute to validate the TLD though. I have the copy and paste code snippet here: https://github.com/coliff/html5-email-regex
I am currently doing homework, and following the instructions the book gives me, but I can't get the required or pattern tags to work. I am creating a survey form, and trying to make an error come up when the user doesn't type in their name, receipt number, or email. Here is a portion of it.
<label for"receipt">Receipt number *</label>
<input name="receipt" id="receipt"
placeholder="re-nnnnnn"
required="required"
pattern="^re\-\d{6}$" />
A few things i see
the required attribute does not need a value, the existence of the attribute is what makes it required or not.
the - does not need to be escaped so use ^re-\d{6}$ for the pattern attribute
the issue with the notepad++ is that the language formatting/color-coding is not up-to-date with all the attributes.
<input name="receipt" id="receipt"
placeholder="re-nnnnnn"
required pattern="^re-\d{6}$" />
there is no need to write like that u can just write : required and it will work
and whats your pattern i don't catch that
CodePen: http://codepen.io/leongaban/pen/hbHsk
I've found multiple answers to this question on stack here and here
However they all suggest the same fix, using type="number" or type="tel"
None of these are working in my codepen or project :(
Do you see what I'm missing?
Firstly, what browsers are you using? Not all browsers support the HTML5 input types, so if you need to support users who might use old browsers then you can't rely on the HTML5 input types working for all users.
Secondly the HTML5 input validation types aren't intended to do anything to stop you entering invalid values; they merely do validation on the input once it's entered. You as the developer are supposed to handle this by using CSS or JS to determine whether the field input is invalid, and flag it to the user as appropriate.
If you actually want to prevent non-digit characters from ever getting into the field, then the answer is yes, you need to use Javascript (best option is to trap it in a keyUp event).
You should also be careful to ensure that any validation you do on the client is also replicated on the server, as any client-side validation (whether via the HTML5 input fields or via your own custom javascript) can be bypassed by a malicious user.
It doesn't stop you from typing, but it does invalidate the input. You can see that if you add the following style:
input:invalid {
border:1px solid red;
}
I use a dirty bit of JS inline, it's triggered upon paste/keying (input).
Within your input tag add the following:
oninput="this.value=this.value.replace(/(?![0-9])./gmi,'')"
All it's doing is replacing any character not 0-9 with nothing.
I've written a tiny demo which you can try below:
Numbers only: <input oninput="this.value=this.value.replace(/(?![0-9])./gmi,'')"></input>
Firstly, in your Codepen, your inputs are not fully formatted correctly in a form.... Try adding the <form></form> tags like this:
<form>
<lable>input 1 </lable>
<input type='tel' pattern='[0-9]{10}' class='added_mobilephone' name='mobilephone' value='' autocomplete='off' maxlength='20' />
<br/>
<lable>input 2 </lable>
<input type="number" pattern='[0-9]{10}'/>
<br/>
<lable>input 3 </lable>
<input type= "text" name="name" pattern="[0-9]" title="Title"/>
</form>
Just add a check to the onkeypress event to make sure that the no alphanumeric characters can be added
<input
type="text"
placeholder="Age"
autocomplete="off"
onkeypress="return event.charCode >= 48 && event.charCode <= 57"
maxlength="10"
/>
How do I send an email with specified initial values for the headers subject and message from a button in html, such as this
<form method="post" action="mailto:email.com?subject=subject&message=message">
where subject and message are values fetched from a form?
You can use mailto, here is the HTML code:
<a href="mailto:EMAILADDRESS">
Replace EMAILADDRESS with your email.
This method doesn't seem to work in my browser, and looking around indicates that the whole subject of specifying headers to a mailto link/action is sparsely supported, but maybe this can help...
HTML:
<form id="fr1">
<input type="text" id="tb1" />
<input type="text" id="tb2" />
<input type="button" id="bt1" value="click" />
</form>
JavaScript (with jQuery):
$(document).ready(function() {
$('#bt1').click(function() {
$('#fr1').attr('action',
'mailto:test#test.com?subject=' +
$('#tb1').val() + '&body=' + $('#tb2').val());
$('#fr1').submit();
});
});
Notice what I'm doing here. The form itself has no action associated with it. And the submit button isn't really a submit type, it's just a button type. Using JavaScript, I'm binding to that button's click event, setting the form's action attribute, and then submitting the form.
It's working in so much as it submits the form to a mailto action (my default mail program pops up and opens a new message to the specified address), but for me (Safari, Mail.app) it's not actually specifying the Subject or Body in the resulting message.
HTML isn't really a very good medium for doing this, as I'm sure others are pointing out while I type this. It's possible that this may work in some browsers and/or some mail clients. However, it's really not even a safe assumption anymore that users will have a fat mail client these days. I can't remember the last time I opened mine. HTML's mailto is a bit of legacy functionality and, these days, it's really just as well that you perform the mail action on the server-side if possible.
As David notes, his suggestion does not actually fulfill the OP's request, which was an email with subject and message. It doesn't work because most, maybe all, combinations of browsers plus e-mail clients do not accept the subject and body attributes of the mailto: URI when supplied as a <form>'s action.
But here's a working example:
HTML (with Bootstrap styles):
<p><input id="subject" type="text" placeholder="type your subject here"
class="form-control"></p>
<p><input id="message" type="text" placeholder="type your message here"
class="form-control"></p>
<p><a id="mail-link" class="btn btn-primary">Create email</a></p>
JavaScript (with jQuery):
<script type="text/javascript">
function loadEvents() {
var mailString;
function updateMailString() {
mailString = '?subject=' + encodeURIComponent($('#subject').val())
+ '&body=' + encodeURIComponent($('#message').val());
$('#mail-link').attr('href', 'mailto:person#email.com' + mailString);
}
$( "#subject" ).focusout(function() { updateMailString(); });
$( "#message" ).focusout(function() { updateMailString(); });
updateMailString();
}
</script>
Notes:
The <form> element with associated action attribute is not used.
The <input> element of type button is also not used.
<a> styled as a button (here using Bootstrap) replaces <input type="button">
focusout() with updateMailString() is necessary because the <a> tag's href attribute does not automatically update when the input fields' values change.
updateMailString() is also called when document is loaded in case the input fields are prepopulated.
Also encodeURIComponent() is used to get characters such as the quotation mark (") across to Outlook.
In this approach, the mailto: URI is supplied (with subject and body attributes) in an a element's href tag. This works in all combinations of browsers and e-mail clients I have tested, which are recent (2015) versions of:
Browsers: Firefox/Win&OSX, Chrome/Win&OSX, IE/Win, Safari/OSX&iOS, Opera/OSX
E-mail clients: Outlook/Win, Mail.app/OSX&iOS, Sparrow/OSX
Bonus tip: In my use cases, I add some contextual text to the e-mail body. More often than not, I want that text to contain line breaks. %0D%0A (carriage return and linefeed) works in my tests.
I couldn't ever find an answer that really satisfied the original question, so I put together a simple free service (PostMail) that allows you to make a standard HTTP POST request to send an email. When you sign up, it provides you with code that you can copy & paste into your website. In this case, you can simply use a form post:
HTML:
<form action="https://postmail.invotes.com/send"
method="post" id="email_form">
<input type="text" name="subject" placeholder="Subject" />
<textarea name="text" placeholder="Message"></textarea>
<!-- replace value with your access token -->
<input type="hidden" name="access_token" value="{your access token}" />
<input type="hidden" name="success_url"
value=".?message=Email+Successfully+Sent%21&isError=0" />
<input type="hidden" name="error_url"
value=".?message=Email+could+not+be+sent.&isError=1" />
<input id="submit_form" type="submit" value="Send" />
</form>
Again, in full disclosure, I created this service because I could not find a suitable answer.
You can not directly send an email with a HTML form. You can however send the form to your web server and then generate the email with a server side program written in e.g. PHP.
The other solution is to create a link as you did with the "mailto:". This will open the local email program from the user. And he/she can then send the pre-populated email.
When you decided how you wanted to do it you can ask another (more specific) question on this site. (Or you can search for a solution somewhere on the internet.)

Even though it is very old and irrelevant now, I am replying to help people like me!
it should be like this:
<form method="post" action="mailto:$emailID?subject=$MySubject &message= $MyMessageText">
Here
$emailID,
$MySubject,
$MyMessageText are variables which you assign from a FORM or a DATABASE Table or just you can assign values in your code itself. Alternatively you can put the code like this (normally it is not used):
<form method="post" action="mailto:admin#website.com?subject=New Registration Alert &message= New Registration requires your approval">
You can use an anchor to attempt to open the user's default mail client, prepopulated, with mailto:, but you cannot send the actual email. *Apparently it is possible to do this with a form action as well, but browser support is varied and unreliable, so I do not suggest it.
HTML cannot send mail, you need to use a server side language like php, which is another topic. There are plently of good resources on how to do this here on SO or elsewhere on the internet.
If you are using php, I see SwiftMailer suggested quite a bit.
<form action="mailto:someone#example.com" method="post" enctype="text/plain">
Name:<br>
<input type="text" name="name"><br>
E-mail:<br>
<input type="text" name="mail"><br>
Comment:<br>
<input type="text" name="comment" size="50"><br><br>
<input type="submit" value="Send">
<input type="reset" value="Reset">
I have a form, text input and a submit button. How do I append the value of the text box to the form action i.e.
action="https://www.mywebsite.com/" & txtSessionId
The form looks like this:
<form name="form1" method="post" action="https://www.mywebsite.com/">
<label>Your Sessions ID:
<input type="text" name="txtSessionId" id="txtSessionId">
</label>
<label>
<input type="submit" name="btnContinue" id="btnContinue" value="Continue">
</label>
</form>
I want the link to look like this: https://www.mywebsite.com/123456
where 123456 is typed into the text box by the user.
Thank you
You'd have to either use javascript or something server-side to do that (or both).
Javascript:
<form name="form1" method="post" action="https://www.mywebsite.com/"
onsubmit="location.href = this.action + this.txtSessionId.value; return false;">
Server-side (PHP)
if (!empty($_POST['txtSessionId']))
{
header('Location: https://.....' . (int)$_POST['txtSessionId']);
exit();
}
The correct behavior is to send the input field to the existing form, process it, and redirect. You don't know if the user sent a valid input value yet!
In this cases I always recommend javascript unless accessibility is an strict requirement for you.
I assume you are using something like mod-rewrite on your server if you are accepting URLs like this. So, why not just write a rule on there to check if txtSessionId is set and then re-write it to whatever you'd like?
I don't know how to write mod-rewrite rules all that well, but, I definitely know you can do it.
If you're using PHP, Greg did present a fairly viable alternative to using mod-rewrite (or something similar).
