Hi There,

I have a webpage with link of useful websites. Rather than loading the websites in a new window, I would an "inline frame/window" to be opened just ow the link I clicked on so that I can preview/interact with the webpage.

Does anyone know how this can be done ?

Here's a reference link I found. http://clusty.com (do a search then click on teh magnifying glass icon)

Thanks in advance.

hi sean,

i am looking to create this URL preview on a site i am creating, on a mouse over event.

After finding this thread and noticing it does exactly what i want i am really looking to see some code on how it works or if there is a place i can be referred to in order to get this solution?

Thanks zensmitty

Did you mean loading an iframe dynamically or static?

I think it would be more efficient to make it dynamic since you don't want to have to load many iframes.

Try: preview.js

function preview(obj) {
	if (obj.innerHTML)
		closePreview(obj);

	if (obj.href)
		var src = obj.href;
	else
		return false;

	var iframe = document.createElement("iframe");
	iframe.src = src;
	iframe.id = "iframe_" + obj.innerHTML;
	iframe.style.height = "200px";
	iframe.style.width = "400px";
	iframe.style.whiteSpace = "nowrap";
	iframe.style.position = "absolute";

	// Next line takes the number value of link.style.bottom (decimals included) and converts it to a number
	var botPad = /^(\d*[^(px)])*/.exec(obj.style.bottom)[0] / 1;
	botPad += 20; // Amount of px above link
	iframe.style.bottom = botPad + "px";
	document.body.insertBefore(iframe, obj);
}
function closePreview(obj) {
	if (obj.innerHTML)
		var id = "iframe_" + obj.innerHTML;
	else
		return false;

	if (document.getElementById(id)) {
		var iframe = document.getElementById(id);
		iframe.parentNode.removeChild(iframe);
	}
}

Can someone else figure out how to keep the iframe from disappearing when you move the mouse into the iframe?

The following concept has not been formalized! I'll try to add patches as soon as i get my time.

Just simply add all the links you need inside the document.

I've been having a go at this one too. Persistent errors in IE made it rather tough but I think I'm on top of them now.

Try this, it seems reliable in IE6 and FF 3.0.10. It's basically Itsjareds code with a bit of heavy refactoring into a namespace, plus there's only ever one iframe which is reused and which is positioned relative to mouse pos rather than the mouseover-link. I came to the conclusion that you either hide the iFrame onmouseout or you have a close button.

Look at the code in calcPopupCoords(). I wrote it a few weeks ago and have been looking forward to using it again. It's one of those many-liners that eventually boiled down to something neat.

It's more fun with different urls in the four links. Try these:

<body>
<a style="float:left;" href="http://www.google.com" onMouseover="iframePreviewer.preview(this);" onMouseout="iframePreviewer.stopMouseCapture();">Gooooogle!</a>
<a style="float:right;" href="http://www.daniweb.com" onMouseover="iframePreviewer.preview(this);" onMouseout="iframePreviewer.stopMouseCapture();">Daniweb!</a>
