![]() ![]() Here’s the simplest possible example of using the multiple you need the email address that was entered to be restricted further than simply any string that looks like an email address, you can use the attribute pattern to specify a regular expression that the entered text must match in order pass the validation. If the multiple attribute is specified alongside the input element, you will be able to enter multiple addresses instead of a single input.īy adding this boolean multiple attribute, the input can be configured to accept multiple email addresses. ![]() If the multiple attribute is specified, each individual item in the comma-separated list of values must match the regular expression. You can learn more about regular expressions in this Email Regex guide. Using an input pattern provides an extra level of email validation on top of the basic one provided by the input itself. If you need the entered email addresses to be restricted further than any string that seems like a valid email address, you can use the attribute, pattern, to specify a regular expression(Regex) the value must match for it to be valid. However, there is also the option to add additional filtering to ensure that your own specialized needs are met, if you have any. First, there's the standard level of validation offered to all inputs, which automatically ensures that the input type meets the requirements to be a valid email address. There are two levels of content validation available for email inputs. The value must be a number greater than zero, and the default value is 20. size - The size attribute is a numeric value indicating how many characters wide the input field should be.readonly - When this property is enabled, you cannot edit the input field, but only view the text that populates the field.placeholder - This is suggested text that populates the email address by default.For example, email addresses will need to end in to pass the email validation check below: It must be a valid JavaScript regular expression. pattern - The attribute, pattern, when specified, is a regular expression that the input's value must match in order for the value to pass constraint validation.multiple - a boolean, that when true, allows the user can enter a list of multiple e-mail addresses, separated by commas and, optionally, whitespace characters. ![]() ![]() minlength - The minimum number of characters the user can enter into the email input.maxlength - The maximum number of characters the user can enter into the email input.list - The id of a datalist element located in the same document.When setting the HTML input type with email address validation, you can also specify these additional attributes: On browsers that don't support inputs of type email, an email input type falls back to being a standard text input. The input value is validated to ensure that a properly formatted e-mail address populates the field before the form can be submitted. So what exactly is an input type element? These input elements of type email allow the user to enter and modify an e-mail address. That was before HTML5 came along and offered us a far simpler solution, by giving us an input type="email" that will easily validate email addresses! This simple solution is a breeze to implement thanks to HTML5 and provides a basic level of email validation with little to no effort.īefore HTML5, you had to use JavaScript code or something similar to validate it. With HTML5, we can use a dedicated attribute called "type" to specify that we want to accept an e-mail address. What if the person enters their name instead of their e-mail address? Should it still be valid? And how do we deal with those annoying "." and symbols and their placement in the string? Before we dive into email validation in HTML, you can read more about what is email validate if you’d like. As a developer, I've always found it really hard to come up with a straightforward way of validating emails in HTML. We all know what emails are supposed to look like. While email validation seems like a simple concept in theory. ![]()
