Email validation

We can validate the email with the help of JavaScript. Here we check the condition related to any email id, like email if must have "@" and "." sign and also email id must be at least 10 character.

There are many criteria that need to be follow to validate the email id such as:

  • email id must contain the @ and . character
  • There must be at least one character before and after the @.
  • There must be at least two characters after . (dot).

Example

<html>
<head>
<script>
function email_validation() 
{  
var x=document.myform.email.value;  
var atposition=x.indexOf("@");  
var dotposition=x.lastIndexOf(".");  
if (atposition<1 || dotposition<atposition+2 || dotposition+2>=x.length){  
  alert("Please enter a valid e-mail address \n atpostion:"+atposition+"\n dotposition:"+dotposition);  
  return false;  
  }  
}  
</script>  

</script>
</head>
<body>
<form name="myform"  method="post" action="#" onsubmit="return email_validation();">  
Email: <input type="text" name="email"><br/>  
<input type="submit" value="register">  
</form></body>
