that depends on what kind of stuff you want to check in email. good start is detecting "@" and "." characters and also empty space " ". here's how you can do it:

function checkEmail(email) {
     if(email.indexOf("@")!=-1 && email.indexOf(".")!=-1 && email.indexOf(" ")!=-1) {
     alert("Specified email address is invalid");
     return false; }
     else alert("Good email address");
}

that should do it

If you really want to validate an email address, you might want to use a regular expression. See http://regexlib.com/ for examples of some regular expressions that validate email addresses.

Here is my favorite method: (Caution: won't work if scripting is disabled!)

<html>

<head>
<title>Email Check</title>
</head>

<script language="JavaScript">
</script>

<body>
  <form method="POST" onsubmit="return Form_Validator(this)" action="javascript:alert('Email is valid')">
    <input name="Email" value="">
    <input type="submit" value="Validate Email">
  </form>
</body>

</html>
