Variable scope - 2

Question posted by: John Wood (Guest) on July 20th, 2005 11:18 AM

Can anybody explain why my variable imonline is still 1 even though my
onError function has fired , value = 0 when printed by Javascript
document.write at end. I thought that
VAR imonline = 1
should have given me a global variable
TIA

<HTML>

<SCRIPT LANGUAGE="JavaScript">
var imonline = 1;
function imageError(theImage) {imonline=0; document.JWonline.src =
"2_yellow.jpg";}
</script>
</HEAD>

<BODY BGCOLOR="#b5ccb8">
<H2><CENTER>Is the green button loaded 2</CENTER></H2>

<img name="JWonline" src="2_greenx.jpg" align=left border=0
onError="imageError(this)"
onAbort="imageError(this)">

<p>Yellow button indicates offline<br>
Green button indicates online


<SCRIPT LANGUAGE="JavaScript">
document.write("<BR>online=",imonline);
</script>

</BODY>
</HTML>

No it hasn't. When your document.write is executed, the image is still
being loaded (or waiting to fail loading). It will probably not finish
loading/failing the image before the page has been fully processed.
