Hi,
your variables are declared as global, so when you call the init function a
second time, they are overwritten.
Just move these variables and functions inside the Init constructor and it will
be fine (see below).
Yannick
function Init(anchor) {
var SVGRoot = null;
var viewBox = null;
var TrueCoords = null;
var singleTip = null;
var singleBox = null;
var singleText = null;
var tiptspan = null;
function GetTrueCoords(evt)
{
var p1 = SVGRoot.createSVGPoint();
var p2;
var m = SVGRoot.getScreenCTM();
p1.x = evt.clientX;
p1.y = evt.clientY;
p2 = p1.matrixTransform(m.inverse());
TrueCoords.x = Math.round(p2.x*100) / 100;
TrueCoords.y = Math.round(p2.y*100) / 100;
}
function HideTooltip( evt )
{
tiptspan.firstChild.nodeValue = null;
singleTip.setAttributeNS(null, 'visibility', 'hidden');
}
function ShowTooltip( evt )
{
GetTrueCoords( evt );
var targetElement = evt.target;
var targetTspan =
targetElement.getElementsByTagName('desc').item(0);
if ( targetTspan) {
if (targetTspan.firstChild != null)
tiptspan.firstChild.nodeValue =
targetTspan.firstChild.nodeValue; }
if ( '' != tiptspan.firstChild.nodeValue )
{
var outline = singleText.getBBox();
singleTip.setAttributeNS(null, 'visibility', 'visible');
xPos = TrueCoords.x;
yPos = TrueCoords.y-20;
singleBox.setAttributeNS(null, 'height', outline.height
+ 10);
singleTip.setAttributeNS(null, 'transform',
'translate(' + xPos + ',' + yPos + ')');
}
}
SVGRoot = document.getElementById(anchor);
TrueCoords = SVGRoot.createSVGPoint();
singleTip = document.getElementById(anchor + '_singleTip');
singleBox = document.getElementById(anchor + '_singlebox');
singleText = document.getElementById(anchor + '_singleText');
tiptspan = document.getElementById(anchor + '_tiptspan');
SVGRoot.addEventListener('mousemove', ShowTooltip, false);
SVGRoot.addEventListener('mouseout', HideTooltip, false);
if (navigator.appName == 'Microsoft Internet Explorer') {
if (singleText != null) {singleText.setAttributeNS(null,
'class', 'ietiptext' ); }
}
}

Objet: [svg-developers] problem adding multiple SVG's containing event
listeners in HTML5
Hi all,
I've got some SVG files that contain mousemove event listeners to invoke a
script to display a tooltip. If I try to add multiple SVG's to an HTML5 doc,
only the last page shows the tooltips when I run in most browsers. In IE9, I
get the tooltips across all the SVG's. This is my sample HTML file containing
the script and 2 child SVG elements. Any idea what I need to do to get each SVG
to display their unique tooltips?
Thanks!
