Using J Avascript Function As Links

[charts]

Hi,

 

i used "javascript function as links" as described in the docu. see: docs.fusioncharts.com/charts/contents/DrillDown/JavaScript.html

 

i defined the "link" property as follows:

 

link: "Javascript: isJavaScriptCall=true; chartClick(event)"

 

What I want:

I need the position (clientX and clientY) on which the user has clicked into the chart. (I want to display a popup on this position!).

So I need the "event" object of the click-event. My sample above works fine in Chrome, but not in Firefox. Is there another way to get the "event" object of the "click-event" ???

 

thank you
