Create popup window appear and disappear on rollover link - javascript

Hi.
I can suggest u this script, i don't remmeber where i take it but it works as it should in any browser.

example of usage u can see at http://www.pashik.com/portfolio.html

script.js file:
var t_id = setInterval(animate,20);
var pos=0;
var dir=2;
var len=0;

function animate()
{
var elem = document.getElementById('progress');
if(elem != null) {
if (pos==0) len += dir;
if (len>32 || pos>79) pos += dir;
if (pos>79) len -= dir;
if (pos>79 && len==0) pos=0;
elem.style.left = pos;
elem.style.width = len;
}
}

function remove_loading() {
this.clearInterval(t_id);
var targelem = document.getElementById('loader_container');
targelem.style.display='none';
targelem.style.visibility='hidden';
var t_id = setInterval(animate,60);
}


var offsetfrommouse=[15,25]; //image x,y offsets from cursor position in pixels. Enter 0,0 for no offset
var displayduration=0; //duration in seconds image should remain visible. 0 for always.

var defaultimageheight = 40;      // maximum image size.
var defaultimagewidth = 40;      // maximum image size.

var timer;

function gettrailobj(){
if (document.getElementById)
return document.getElementById("preview_div").style
}

function gettrailobjnostyle(){
if (document.getElementById)
return document.getElementById("preview_div")
}


function truebody(){
return (!window.opera && document.compatMode && document.compatMode!="BackCompat")? document.documentElement : document.body
}


function hidetrail(){      
      gettrailobj().display= "none";
      document.onmousemove=""
      gettrailobj().left="-500px"
      clearTimeout(timer);
}

function showtrail(imagename,title,width,height){
      i = imagename
      t = title
      w = width
      h = height
      timer = setTimeout("show('"+i+"',t,w,h);",200);
}
function show(imagename,title,width,height){
 
    var docwidth=document.all? truebody().scrollLeft+truebody().clientWidth : pageXOffset+window.innerWidth - offsetfrommouse[0]
      var docheight=document.all? Math.min(truebody().scrollHeight, truebody().clientHeight) : Math.min(window.innerHeight)

      if( (navigator.userAgent.indexOf("Konqueror")==-1  || navigator.userAgent.indexOf("Firefox")!=-1 || (navigator.userAgent.indexOf("Opera")==-1 && navigator.appVersion.indexOf("MSIE")!=-1)) && (docwidth>650 && docheight>500)) {
            ( width == 0 ) ? width = defaultimagewidth: '';
            ( height == 0 ) ? height = defaultimageheight: '';
                  
            width+=30
            height+=25
            defaultimageheight = height
            defaultimagewidth = width
      
            document.onmousemove=followmouse;

            
            newHTML = '<div class="border_preview" style="width:'+  width +'px;height:'+ height +'px"><div id="loader_container"><div id="loader"><div align="center">Loading preview...</div><div id="loader_bg"><div id="progress"> </div></div></div></div>';
//            newHTML = newHTML + '<h2 class="title_h2">' + ' '+title + '</h2>'
            
          newHTML = newHTML + '<div class="preview_temp_load"><img onload="javascript:remove_loading();" src="' + imagename + '" border="0"></div>';
            newHTML = newHTML + '</div>';
            
            if(navigator.userAgent.indexOf("MSIE")!=-1 && navigator.userAgent.indexOf("Opera")==-1 ){
                  newHTML = newHTML+'<iframe src="about:blank" scrolling="no" frameborder="0" width="'+width+'" height="'+height+'"></iframe>';
            }            

            gettrailobjnostyle().innerHTML = newHTML;
            gettrailobj().display="block";
      }
}

function followmouse(e){

      var xcoord=offsetfrommouse[0]
      var ycoord=offsetfrommouse[1]

      var docwidth=document.all? truebody().scrollLeft+truebody().clientWidth : pageXOffset+window.innerWidth-15
      var docheight=document.all? Math.min(truebody().scrollHeight, truebody().clientHeight) : Math.min(window.innerHeight)

      if (typeof e != "undefined"){
            if (docwidth - e.pageX < defaultimagewidth + 2*offsetfrommouse[0]){
                  xcoord = e.pageX - xcoord - defaultimagewidth; // Move to the left side of the cursor
            } else {
                  xcoord += e.pageX;
            }
            if (docheight - e.pageY < defaultimageheight + 2*offsetfrommouse[1]){
                  ycoord += e.pageY - Math.max(0,(2*offsetfrommouse[1] + defaultimageheight + e.pageY - docheight - truebody().scrollTop));
            } else {
                  ycoord += e.pageY;
            }

      } else if (typeof window.event != "undefined"){
            if (docwidth - event.clientX < defaultimagewidth + 2*offsetfrommouse[0]){
                  xcoord = event.clientX + truebody().scrollLeft - xcoord - defaultimagewidth; // Move to the left side of the cursor
            } else {
                  xcoord += truebody().scrollLeft+event.clientX
            }
            if (docheight - event.clientY < (defaultimageheight + 2*offsetfrommouse[1])){
                  ycoord += event.clientY + truebody().scrollTop - Math.max(0,(2*offsetfrommouse[1] + defaultimageheight + event.clientY - docheight));
            } else {
                  ycoord += truebody().scrollTop + event.clientY;
            }
      }
      gettrailobj().left=xcoord+"px"
      gettrailobj().top=ycoord+"px"

}

IN ur HTML file:
don't forget to include <script language="javascript" type="text/javascript" src="script.js"></script>
and write in after <body> tag
<div style="display: none; position: absolute;z-index:110; " id="preview_div"></div>

And on image/text where u want to have mouseover popup write this:

<a style="cursor: hand" href="http://www.yahoo.com" target="_blank" onfocus="showtrail('images/largeYahoo.jpg','Yahoo.com',400,439)" onmouseover="showtrail('images/largeYahoo.jpg','Yahoo.com',400,439)" onmouseout="hidetrail()" onblur="hidetrail()" ><img src="images/smallYahoo.jpg" alt="Yahoo.com" border=0 class="thumbnail" longdesc="" width="145" height="134"></a>

Thats really good - although not exactly what I was looking for. The behaviour of this script is more like the popup window that you get on istock.com

I need to allow the user to move their mouse inside the popup box (which will contain text and images) to click on a link.

Thanks for your suggestion though

Not exactly what you are looking for, but this could be modified easily to do what you are asking.  This actaully was designed to simulate a modal dialog box without a pop-up window.  You could easily remove the code that disables the rest of the page and add an onmouseout option to the <div's> that hold your pop-up information.

If it looks like this might work for you and you need help with it, let me know.

Thanks for the suggestion - Its not what I was looking for. Is there a way of extracting the code from the  example page ( http://www.revelation.uk.com/beta/rollover/Autos%20-%20Text%20Link%20Ads.htm ) that I sent?

I managed to fix this myself using div's and the hidden status:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<SCRIPT type=text/javascript>
function showstuff(boxid){
   document.getElementById(boxid).style.visibility="visible";
}

function hidestuff(boxid){
   document.getElementById(boxid).style.visibility="hidden";
}
</SCRIPT>
<style type="text/css">
<!--
#apDiv1 {
      position:absolute;
      width:200px;
      height:115px;
      z-index:99;
      left: 11px;
      top: 21px;
      visibility: hidden;
      background-color: #0000FF;
}
-->
</style>
</head>

<body>
<div id="apDiv1" onmouseover=showstuff('apDiv1') onmouseout=hidestuff('apDiv1')>
  <p>tHIS IS A TEST</p>
  <p>&nbsp;</p>
  <p>asdsa</p>
</div>
<p><A onmouseover=showstuff('apDiv1')
      onmouseout=hidestuff('apDiv1') href="javascript:void();">Put your mouse here</A></p>
<p>&nbsp;</p>
</body>
</html>

Somewherehot: Very simple and nice script. It is appreciated. I am going to use it (modified) in greasemonkey to create a sort of lightbox script that will allow me to open images in the same page as they are linked in.

Thanks!
