SVG and JavaScript

[Raoul.Kamadjeu]

I'm trying to open a new window from an SVG document (a map). A new
window will popup when the user clicks on an SVG polygon.
The SVG document is generated by a php function
The JavaScript function resides on an external file

function open_me(url) {
window.open('url');
}

I use this piece of code to open the new window
<a href="javascriptvoid)" onclick="open_me('http://www.google.com');"
target="_blank">

This doesn't work. I got the error message "window.open is not a
function".
I tested the same routine with window.alert and it works fine.
What is wrong here?. Why window.open is not recongnized as a function
in this case and window.alert is?

Why don't you simply use an SVG link element to open the new window e.g.
<a xmlns:xlink="http://www.w3.org/1999/xlink"
xlink:href="http://example.com/"
xlink:type="simple"
target="_blank">
<rect x="10" y="10"
with="30" height="30"

This doesn't work. I got the error message "window.open is not a

Depending on the SVG implementation that window object might simply not
implement a method named open. If the SVG is embedded inside of an HTML
document in a browser where the window object supports a method named
open then try e.g.
if (typeof window != 'undefined' &&
typeof window.open != 'undefined'
{
window.open('http://example.com');
}
else if (typeof parent != 'undefined' &&
typeof parent.open != 'undefined')
{
parent.open('http://example.com/');
}

Thanks for your reply. I implemented the piece of code you proposed .
The error message doesn't show anymore, but the page doesn't pop up.

Which software is used to render the SVG and execute the script?

The SVG map was obtained by converting MapInfo shape file into SVG,
using Map2Svg.
The SVG map is embeded into a php file. I used Internet Explorer 6
(Adobe SVG Viewer). The fill property of the SVG polygons are
controlled by a php function, based on the district coverage value
returned by a query to a MySQL database
You can get an overview of this project at

Select a country, an antigen and a year. I want the user to access
additional information by clicking on a district polygon.
Thanks
