You might have better luck on the client side JavaScript programming forum. As this is the server side (PHP) scripting forum.

Yes indeed. Moving from PHP to Javascript.

Here you are:-


<form name= "form1">
<input type = "text" name = "txtEmail" onblur ="chkemail(this)">
</form>

<script type = "text/javascript">

function chkemail(which) {
var email = which.value;
if (!/^([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/.test(email)) {
alert("Please enter a valid email address!");
which.value = "";
myfield = which; // note myfield must be a global variable
setTimeout('myfield.focus();myfield.select();' , 10); // to overcome a bug in Firefox
return false;
}
return true;
}

</script>
