[RESOLVED] Defining an object

Copy linkTweet thisAlerts:
Jul 07.2008

I have a web page at:

[url]http://myweb.tiscali.co.uk/spiresgate/StEdwardsWeb/pupils.htm[/url]

which has clean HTML according to Tidy and validates according to W3C.

However, I have an ‘error on page’ message (bottom left-hand corner) which reads ‘Inn’ is undefined. I have tracked down to the external javascript file. The lines it doesn’t like are:

Inn.style.top = 150 + 90 – tempY*4;
Inn.style.left = 100 + 90 – tempX*4;

How do I define this object Inn?

@FangJul 07.2008 — What are you using the cursor position values for?

@spiresgateauthorJul 07.2008 — Good question.

The external file is used for other pages on the site. The user moves the cursor over a group photograph and a magnification of that part of the picture is seen in a separate box. For example at:

http://myweb.tiscali.co.uk/spiresgate/StEdwardsWeb/2alpha.htm

@FangJul 07.2008 — This is one way to solve it:if(document.getElementById('Inn')) {
var Inn=document.getElementById('Inn');
Inn.style.top = 150 + 90 - tempY*4;
Inn.style.left = 100 + 90 - tempX*4;
}
You also have a problem on 2alpha.htm as the image name [I]Oldtimes[/I] does not exist.

@spiresgateauthorJul 07.2008 — Thanks very much Fang. That seems to have done it. I should be able to put similar errors right with this new 'learnings'.

Success!
