Default Why isn't this working?

Here is my code with some comments:


<SCRIPT LANGUAGE="JavaScript">
var mkdiv = document.createElement('div'); //create your div
var timer //create timer variable
function showItem(posleft, postop, w, h, linkdetail, n)

//posleft = position from the left
//postop = position from the top
//w = pixelwidth
//h = pixelheight
//linkdetail = URL to be shown in the revealed div
//n = text for URL to be shown in the revealed div
//linkno = string built from linkdetail + n to give innerHTML string for divs innerHTML property.


{

linkno ="<a href = " + "\"" + linkdetail + "\"" + ">" + n + "</a>"

    window.clearTimeout(timer)

    mkdiv.style.backgroundColor = "lightblue";
    mkdiv.style.border = "1px solid black";
    mkdiv.style.visibility = "visible"
    mkdiv.style.pixelLeft = posleft
    mkdiv.style.pixelTop = postop
    mkdiv.style.pixelWidth = w
    mkdiv.style.pixelHeight = h
    mkdiv.style.zIndex = 1
    mkdiv.innerHTML = linkno
    //all of this syntax looks fine to me, Im just setting variables using arguments!
    timer = window.setTimeout("hidewin()", 5000)
}

function hidewin(){
mkdiv.style.visibility = "hidden"
}

</SCRIPT>

<a href = "#" onmouseover="showItem(100, 20, 100, 20, this.linkdetail, this.linktext)" linkdetail = "www.google.com" linktext = "Google">Show Link 1</a><br>
<a href = "#" onmouseover="showItem(100, 40, 100, 20, this.linkdetail, this.linktext)" linkdetail = "www.yahoo.com" linktext = "Yahoo">Show Link 2</a>

The script is running without any complaints, but I can't see the div at all! Any ideas? All arguments are passed in on the onmouseover event, such as width and height, position, stuff like that, but I just cannot see the divs as they are 'supposed' to appear.

Help much appreciated.

Joe

Hi Joe,

It looks like you are creating the div, but never actually appending it to any element in the page.

Try adding this to your script block...
Code:
window.onload = function(){
    document.body.appendChild( mkdiv );
};
I think you may also want to set style.position = "absolute" for the div

HTH,

Chris

Hi Chris,

Thanks for the tip. You were right, I wasn't appending to an element, but instead of using your piece of script I used:

document.body.insertBefore(mkdiv)

You were right on the positioning too. Thanks for the help!

Joe
