alert onload

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

<body onload="if(document.forms['FORM_NAME']['TEXTAREA_NAME'].value.length>0)alert('Textarea has value')"....

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

Code:

<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:

Code:

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.

document.myForm.txtArea.focus();

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:

Code:

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();
}
}
