I have the following HTML for making sure password length is over 8 characters:
<label>Password <small>required</small>
<input type="password" name="password" id="password" required pattern=".{8,}">
</label>
<small class="error">Your password must be at least 8 characters long.</small>
This works. However, if in a different field I use the pattern [a-zA-Z]+, like this:
<label>Username <small>required</small>
<input type="text" name="username" required pattern="[a-zA-Z0-9]+">
</label>
<small class="error">Username must consist out of letters or numbers only.</small>
It will allow everything. If I change the pattern in the username field to .{8,}, it will only allow inputs that are over 8 characters in length, as expected. Why does the pattern for the username field not work?
The documentation states that this is the correct way to do it:
<label>Your name <small>required</small>
<input type="text" required pattern="[a-zA-Z]+">
</label>
<small class="error">Name is required and must be a string.</small>
The fix is to wrap the pattern in line begin and end characters, like such:
<input type="text" name="username" required pattern="^[a-zA-Z0-9]+$">
Maybe this is a bug in Foundation that needs to be reported on their Github?

I am having issues with getting a "Phone Number" input validated. I have written the regex pattern to require 10 numbers, but even when I plug in 10 numbers into the input field, I still get the error message: "Please match the requested format" and can't seem to figure out why this is.
All help and advice is greatly appreciated!
<input type="text" id="number" name="number" pattern="/^\d{10}$/" required>
Here is a code example from this page: https://www.w3schools.com/html/html_form_input_types.asp
You can directly do it with an in-build functionality of HTML.
Just use the type type="tel" and you should be good to go.
if you want 10 consecutive numbers without - you can also do: pattern="[0-9]{10}"
<form>
<label for="phone">Enter your phone number:</label>
<input type="tel" id="phone" name="phone" pattern="[0-9]{3}-[0-9]{2}-[0-9]{3}">
</form>
Just place you're input in a <form> and hit submit. It should now match.
I don't believe you need the forward slashes in your regex pattern here.
Try this:
<input type="text" id="number" name="number" pattern="^\d{10}$" required>
I have the task of using a password field which checks if it has at least 8 characters, consists of at least 1 uppercase character, 1 lowercase character and 1 digit. How can I do this in the HTML input field using the pattern attribute?
Thank you.
You can use pattern for validation.
<input type="password" id="pass" name="pass" pattern="(?=.*\d)(?=.*[a-z])(?=.*[A-Z]).{8,}" title="Must contain at least one number and one uppercase and lowercase letter, and at least 8 or more characters">
You can learn more here
However, if you ever wanted to use some javascript, then HTML5 does enable some validation, even pattern matching, but I'm pretty sure you'd need some javascript to have this working and also compare the two values with confirm password field as well.
You can try this
<input id="password" name="password" type="password" pattern="^\S{8,}$" onchange="this.setCustomValidity(this.validity.patternMismatch ? 'Must have at least 8 characters' : ''); if(this.checkValidity()) form.password_two.pattern = this.value;" placeholder="Password" required>
<input id="password_two" name="password_two" type="password" pattern="^\S{8,}$" onchange="this.setCustomValidity(this.validity.patternMismatch ? 'Please enter the same Password as above' : '');" placeholder="Verify Password" required>
if we uses "tel" in input then we can give max or min length for the input but its drawback is it may take all kind of inputs whether it is numeric or alphabets,
And if we uses "number" for input then it takes only number but we can not give it min-max characters limit.
Even though I have mentioned pattern inside it but no change.
So is there any alternate for the same to give max-min length and can take only numeric?
<div class="form-group">
<label for="exampleFormControlInput3">Mobile Number</label>
<div class="input-group">
<span class="input-group-text" id="basic-addon1">+91</span>
<input type="tel" class="form-control" id="exampleFormControlInput3" maxlength="10" placeholder="012-345-6789" pattern="[0-9]{3}-[0-9]{2}-[0-9]{3}">
</div>
</div>
Note: I have used bootstrap5 for the same.
You using input type tel and can make a mix with javascript if you want avoid completely alphabetic characters. The type tel provides pattern to but it validate afterwards. And not every browser will supported.
<label for="phone">Enter your phone number:</label>
<input type="tel" id="phone" name="phone"
maxlength ="6"
pattern="[0-9]{3}-[0-9]{3}"
oninput="this.value = this.value.replace(/[^0-9.]/g, '').replace(/(\..*?)\..*/g, '$1');"
required>
<small>Format: 123-456</small>

Semantically using type="number" is incorrect. You should be only using type='tel'. If you want fine control over what the user inputs, you should be using a pattern for that.
<input type="tel" id="phone" name="phone"
pattern="[0-9]{3}-[0-9]{3}-[0-9]{4}"
required>

Currently I have built a password form like this.
<input id="password" name="password" type="password" minlength='6' ng-model="model.password"
placeholder="Password"
required/>
Here password length is more than 6.
But default users have no password and allow 0 length password.
I have no idea how to do this.
Must look like this(not using javascript)
<input id="password" name="password" type="password" length='0 || > 6' ng-model="model.password"
placeholder="Password"
/>
Is this even possible?
You want to use this:
<input id="password" name="password" type="password" ng-model="model.password" placeholder="Password" pattern="|.{6}.*" />
required enforces the field must be non-empty. Do not use it.
The number in the code means minimum lenght. See description.
Description:
Use a pattern attribute here. It defines a RegEx (regular expression) that describes the content. The check is done by browser. Check it also on server-side.
Example:
<input pattern="|......+" />
Pattern description:
| means "or" (Empty string (left side) or ......+ (right side))
. means any character (only one)
.+ means one or more characters.
Use more dots (.) to set longer string.
If you want to use number, use this:
<input pattern="|.{6}.*">
The number between { and } is length.
.{number} means a string with fixed length.
.* means a string (0 or more characters)
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">
