The following email is not accepted with a period, is this a regular expression issue or some bug.
This works
abcdefg.jijklmn#abcdedghijklmnopgi.com
but the following doesn't (note uppercase letter in the email "A" and "J"), i think that is the problem
Abcdefg.Jijklmn#abcdedghijklmnopgi.com
Html element
<input type="email" class="form-control" name="email" pattern="[a-z0-9._%+-]+#[a-z0-9.-]+\.[![\[][1]][1]a-z]{2,3}$" required="" value=""/>
Error below
It's because your regex doens't allow capitals.. simply allow capitals..
[a-zA-Z0-9._%+-]+#[a-z0-9.-]+\.[![\[][1]][1]a-z]{2,3}$
Regular expressions for emails can be very difficult. However, you don't actually need to use a pattern to validate emails as type="email" does that for you. Simply remove the pattern entirely and the clients browser will validate the email for you using their in-built regex
<input type="email" class="form-control" name="email" required="true" value=""/>
I can't actually seem to get email validation to work with the pattern attribute at all, as I think it's competing with type="email".

Using Html5 I've a view which contains an email input field.
So to validate the correct email address I am using pattern attribute for validation.
But that is not working correctly, the problem I am facing here is though I enter invalid email address as abc#gmail the validation is not working.
i tested the same regex pattern in fiddler, it is working fine there, but coming to my application it is not working correctly. Please help me out with this.
Here is my view:
<form>
<input type="email"
class="form-control"
data-val="true"
data-val-required="please enter an email address"
pattern="[a-z0-9._%+-]+#[a-z0-9.-]+.[a-z]{2,4}$"
required>
<input type="submit" />
</form>
Regex should be
[a-z0-9._%+-]+#[a-z0-9.-]+.[a-z]{2,}$
instead of
[a-z0-9._%+-]+#[a-z0-9.-]+.[a-z]{2,4}$
So the html input would be:
<input type="email"
class="form-control"
data-val="true"
data-val-required="please enter an email address"
pattern="[a-z0-9._%+-]+#[a-z0-9.-]+\.[a-z]{2,}$"
required>
NOTE: difference in regex is {2,} and {2,4}
I am trying to come up with a valid pattern for an HTML form. I would like to allow *#student.*.edu.vn
This is my code:
<input
type="text"
name="mail"
pattern="([a-z]|[0-9])+(#{1})+(student)+(.)+[a-z]+(.edu.vn)"
/>
It does not work as I would like. What I am doing wrong?
The pattern (regular expression) is slightly wrong as you haven't escaped all your special characters such as the . and have some unnecessary parts within it. Try using the following slightly modified pattern instead:
([a-z]|[0-9])+#student\.[a-z]+\.edu\.vn
<form>
<input type="text" name="mail" pattern="([a-z]|[0-9])+#student\.[a-z]+\.edu\.vn" />
<input type="submit">
</form>
Note: Make sure that you also do validation on the server-side as anyone entering values into a form can remove the pattern to bypass this check.
I came up with this solution which is slightly more easy to read and is less strict (which is a good thing because e-mail addresses can contain a lot more characters than just lowercase alpha-numeric ones. Don't forget to do proper validation on the backend using an e-mail validator.
<form>
<input
type="text"
name="mail"
pattern=".+#student\..+\.edu.vn"
/>
<input type="submit">
</form>
how to use ng-mask for validation of phone number having pattern (xxx)xxx-xxxx . I tried using "pattern" in the input html tag but not satisfied with the result
because each time when user enters the phone number, the user must type both '()' and '-',and this will make the user annoying. So suggest a way to overcome this.
<input type="tel" name="phoneno" maxlength=13 ng-model="phone.number" pattern="^(?:\(\d{3}\)|\d{3}-)\d{3}-\d{4}$" required/></div>
This should work:
<input type="text" ng-model="phone.number" name="phone" mask="(999) 999-9999" clean="true" ng-model="phone">
I am new to HTML,can any one please help me to validate a phone number only with '+' and numeric values and phone number shud not exceed 13 numbers,and to validate email with a '#' and a '.',I dont want to use javascript
In HTML5 you can use <input type='tel'> and <input type='email'>
You can also specify a specific pattern like <input type='tel' pattern='[\+]\d{2}[\(]\d{2}[\)]\d{4}[\-]\d{4}' title='Phone Number (Format: +99(99)9999-9999)'>
Something like pattern='^\+?\d{0,13}' Would give you an optional + and up to 13 digits
Email Validation - <input type="email" />, use the type as email.
Telephone number validation - <input type="tel" />. use the type as tel.

HTML5 phone number validation with pattern
HTML5 Email Validation
HTML and/or JavaScript will only validate email on client side, the more secure solution would be to validate email on the server side.
Having said that you can do basic validation in HTML 5 like
<form>
<input type="email" placeholder="Your email" required>
<input type="submit" value="Submit">
</form>
i have a text field for email which is set to required, i want it to show a text that you need to include "#" on your email. like how it displays "fill out this field" when you pressed the button without typing anything on the field. How can i do it? Thanks.
EXAMPLE:
<input type="text" name="email" required>
You can try to use the type in case you are using HTML5 as:
<input type="email" name="email" required>
If you are not using the HTML5 then you need to use some scripting language like Javascript to check the validity. For example in Javascript it would be like:
if(!document.getElementById("email").checkValidity())
In case of PHP it would be like
if (filter_var($email, FILTER_VALIDATE_EMAIL))
You can check it by using (since HTML5):
<input type="mail" name="email" required>
It will display a warning if format is not correct (tooltip, or red color around the field, depending on your browser.
Or you can check it on the server side, once you form is sent. For example with PHP, you can use filter_var
Use pattern attribute,
<input type="text" name="email" pattern=".*[#]+.*" />
<input type="email" name="email" required />
