Vue Js Get Domain Name from Email Address: To get the domain name of an email address in Vue.js, you can use JavaScript’s string manipulation functions to extract the domain name from the email address. One approach is to split the email address string into two parts using the “@” symbol as the delimiter. Then, you can take the second part of the split array and remove any potential subdomains or special characters using regular expressions or other string manipulation functions.

How to extract domain name from email in Vue.js using JavaScript string methods?

This code snippet is a Vue.js application that allows users to input an email address and extracts the domain name from it. The app contains an input field for the email address and two paragraphs for displaying the extracted domain name and any error messages.

The Vue.js instance is created and bound to the #app element in the HTML. The app’s data object contains three properties: email, domain, and errorMessage. The email property is used to store the user’s email input, domain is used to store the extracted domain name, and errorMessage is used to store any error messages that may occur during input validation.

The checkEmailValidity() method is called whenever the input field changes. It checks the validity of the email address and sets the appropriate error message in errorMessage. If the email address is valid, it calls the extractDomain() method to extract the domain name.

The extractDomain() method uses the split() method to split the email address at the “@” symbol and stores the domain name in the domain property. It also uses a regular expression to remove any leading “www.” from the domain name.

Overall, this app provides a simple and user-friendly way to extract domain names from email addresses using Vue.js.
