error checking with javascript

[rakennedy75]

I realize this might not be the appropriate forum for this question but I don't know of any good javascript forums. Besides this is probably and easy question for most of you.

I am doing a basic form error check in php. I have all the errors populate a variable and the variable is being displayed to the user as an alert box.

My question is , when displaying text in an alert box, how can break the lines. I tried the "\n and \r an <br> tags and none of these work. Basically the alert box will say... "Pleas fill out the missing fields: ..

and a new line will display the list of errors.

I hope this makes sense, thanks for your time.

I was mistaked on this. In the actual javascript alert function the \n will work to break the lines up. However I found that my problem is using it with php.

here is an example of what I am doing

function error_msg($msg){ <script>alert($msg);</script> }

if ($var1 == ""){ $error .= $var1." field\n"; }
if ($var2 == ""){ $error .= $var2." field\n"; }
if ($var3 == ""){ $error .= $var3." field\n"; }

if($error != "")
{
    error_msg("fill out:\n".$error);
}

What is happening is it breaks the alert box so the code is reading the new line
but it is breaking the actual alert box so the page doesn't display it as an alert box.

Is there a way to force it so it is recognized in the string.

the newline (\n) works find when you use it directly in a javascript function without the php code. Any ideas on how to fix this would be great.

Thanks for your time.

Escape the \n as it's also a PHP newline: \n
