You should practise indenting your code (and adding comments), it makes your code readable.

The only thing which is remain is character counting how much letter submitted in input box.

alert box must show counted characters + valid or invalid email + message

Code:

<html>
<head>
<script type="text/javascript">
function CheckMyEmail()
{
var x=document.forms["myForm"]["email"].value;
var value=("BC102034568");
var at=x.indexOf("@");
var dot=x.lastIndexOf("vu.edu.pk");
if (at<1 || dot<at+1 || dot+2>=x.length)
{
alert( x + " is Not your valid VU e-mail address");
return false;
}
else
{
    if(x=="BC102034568@vu.edu.pk")
        {
        alert( x + " is your valid VU e-mail address");
        return false;
        }
else
{
alert( x + " is not an valid email address");
return false;
}
}
}
</script>
</head>

<body>
<form name="myForm" action="example.html" onsubmit="return CheckMyEmail();" method="post">
Email: <input type="text" name="email">
<input type="submit" value="Submit">
</form>
</body>

</html>

you again forgot to make return function well i done it.

if someone submit more then 40 characters email the alert box show email it too much large of some one enter minimum characters like 2 or 3 character alertbox must show email characters are less.

PHP Code:


if (x.length >= 40) {
alert("Too much");
} else if(x.length =< 3) {
//ahh;
alert("Too Less");
} else {
//ok;
}

but how i can implement your code in fields ?

Code:

if (x.length >= 40) {
alert("Too much");
} else if(x.length =< 3) {
//ahh;
alert("Too Less");
} else {
//ok;
}

Before checking any other checks

PHP Code:


<html>
<head>
<script type="text/javascript">
function CheckMyEmail()
{
var x=document.forms["myForm"]["email"].value;

if (x.length >= 40) {
alert("Too much");
} else if(x.length =< 3) {
//ahh;
alert("Too Less");
} else {
//ok;
var value=("BC102034568");
var at=x.indexOf("@");
var dot=x.lastIndexOf("vu.edu.pk");
if (at<1 || dot<at+1 || dot+2>=x.length)
{
alert( x + " is Not your valid VU e-mail address");
}
else
{
    if(x=="BC102034568@vu.edu.pk")
        {
        alert( x + " is your valid VU e-mail address");
        return true;
        }
else
{
alert( x + " is not an valid email address");
}
}
}
return false;
} 

</script>
</head>

<body>
<form name="myForm" action="example.html" onsubmit="return CheckMyEmail();" method="post">
Email: <input type="text" name="email">
<input type="submit" value="Submit">
</form>
</body>

</html>

Ahh, yeah, a small type in the comparison operator: =<

PHP Code:


<html>
<head>
<script type="text/javascript">
function CheckMyEmail()
{
var x=document.forms["myForm"]["email"].value;

if (x.length >= 40) {
alert("Too much");
} else if(x.length <= 3) {
alert("Too Less");
} else {
//ok;
var value=("BC102034568");
var at=x.indexOf("@");
var dot=x.lastIndexOf("vu.edu.pk");
if (at<1 || dot<at+1 || dot+2>=x.length)
{
alert( x + " is Not your valid VU e-mail address");
}
else
{
    if(x=="BC102034568@vu.edu.pk")
        {
        alert( x + " is your valid VU e-mail address");
        return true;
        }
else
{
alert( x + " is not an valid email address");
}
}
}
return false;
} 

</script>
</head>

<body>
<form name="myForm" action="example.html" onsubmit="return CheckMyEmail();" method="post">
Email: <input type="text" name="email">
<input type="submit" value="Submit">
</form>
</body>

</html>
