This depends on whether you're talking about Mozilla with native SVG support, or Mozilla with the ASV 6 alpha installed. ASV does not support scripting to and from Mozilla, and I guess they will wait until they finalise ASV 6 before adding that support, so forget about scripting between the two documents in this case. At the moment if you want to embed SVG by reference into an HTML file, Mozilla with native SVG will support direct script access from the HTML to the SVG if you use the <object> or <iframe> tags. Currently the <embed> tag does not allow you to script from the HTML to the SVG document directly. (I plan to write a patch to add a contentDocument attribute or getSVGDocument method to the 'embed' object, but unfortunately I'm unlikely to get to this before SVG is built into the official Mozilla 1.8 (hopefully) builds.) If you want to script across <embed> you will need to push a reference to the SVG document up to the HTML document first. Since ASV has removed the script link between itself and IE if the SVG is embeded using the <object> tag I would imagine that you are using the <embed> or <iframe> tag. To create a link between the HTML and SVG document for Mozilla put something like the following in a script in your SVG document. top.svgDoc = document; // creates a reference in the HTML to the SVG document top.svgWin = window; // creates a reference in the HTML to the SVG document's 'window' Scripts in your HTML document can then check for window.svgDoc and window.svgWin and use them once they've been set. > My question is: how are most people developing their svg sites, > especially map sites?
