Hi All

I am having some problems with a javascript calendar I have. I really like it and want to carry on using it, however there seems to be a problem with it with different browsers.

Firstly, I created a small page to show the problem (below) and the popcalendar.js file attached as code.

Firstly, with IE the <body onload = "insertfields('Automaticly inserted');"> does not put the text into the field as required, however the calendar works perfectly.

With FX, the <body onload = "insertfields('Automaticly inserted');"> puts the text into the field perfectly, but the calendar does not display when the input box is clicked. The calendar does work with FX if I take the <body onload = "insertfields('Automaticly inserted');"> out, however the calender is always displayed in the top left of the page and not belwo the field like in IE.

So I need 2 things:
1) The body onload must work with both IE and FX and insert the field properly.
2) With FX, the calendar must be displayed below the input field like in IE.

I have really been struggling with this and dont know what it is. I would assing more than 500 points if I could.

Thanks in advance.
Leon

The body onload attribute interferes with window.onload statement in popcalendar.js.
To solve this, you could remove the window.onload = init statement from the popcalendar.js and insert it int the onload attribute of the body.

Look at this article : http://rainbow.arch.scriptmania.com/scripts/multiplejava.html

To position the calendar below the input, you need to modify the popcalendar script file a little bit.
@ Line 579 (where left and top of the style obejct are being set) you need to append it with "px"

Tested in FF 3.06 and IE7
<body onload="insertfields('Automaticly inserted'); init();">
 
crossobj.left =	fixedX==-1 ? (ctl.offsetLeft + leftpos) + "px" : fixedX + "px";
crossobj.top = fixedY==-1 ? (ctl.offsetTop + toppos + ctl.offsetHeight + 2) + "px" : fixedY + "px";
