How can I alert onLoad for a text area only if it has text filled in only when that particular customer name is selected?
Please help

Well without knowing the name of the text area, you'd have to do something like this:

<html>
<head>
<title>temporary file</title>

<script>
function alertMsg(){

if (document.myForm.txtArea.value != null){
alert("The textarea has text in it");
}
}
</script>

</head>
<body onLoad="JavaScript:alertMsg();">

<form name="myForm">
<textarea name="txtArea">value....</textarea>
</form>


</body>
</html>

Thanks a lot!!
and If I have to get a alert box when either one of the two textarea has comments? What should I do then?

So you want an alert message if either of two boxes has text in it?

If so swap the original if statement for this one:

if ((document.myForm.txtArea1.value != null)&&(document.myForm.txtArea2.value != null)) {
[...]

It works fine.
How can we get the focus to that text area where the length >0 that means after alert.
Thank you in advance.

Can you Specify where do I place the focus() line???/
function validate(){
if((document.forms['general_form']['comments'].value.length>0)||
(document.forms['general_form']['custentitydrxcomments'].value.length>0)){
alert('Please check the comments before making any changes.');
}
}

Uhm...you want it right after the alert? All you have to do is add that line:

function validate(){
if((document.forms['general_form']['comments'].value.length>0)||
(document.forms['general_form']['custentitydrxcomments'].value.length>0)){
alert('Please check the comments before making any changes.');
document.myForm.txtArea.focus();
}
}
