There's a complete example on the Adobe SVG Preview site in the 
Transformations tutorial.  Here's an overview:

Using JavaScript on an HTML page to interact with a SVG graphic

1. There are several ways to get a reference to the desired SVG 
graphic on the page.
a.  Get a reference to the first SVGDocument on the page
   var svgdoc = document.embeds[0].getSVGDocument();

   (embeds[0] is the first plugin,  and embeds[1] is the second 
plugin, etc.)
   or
b. Get a reference to the SVG graphic named "SVGtoScale"
   var svgdoc = document.embeds["SVGtoScale"].getSVGDocument();

   The embeded plugin must be named on the HTML page as in:
   <EMBED SRC="Scale2.svg" WIDTH="250" HEIGHT="200" NAME="SVGtoScale">

2.  Once you have a reference to svgdoc, get a reference to the 
desired element in the SVG graphic.  In this case "AreaToMove"
   var svgobj = svgdoc.getElementById("AreaToMove");

   Snippet from the SVG file:
   <g id ="AreaToMove" >
<rect x="20" y="20" width="80" height="80"
      style="fill:yellow; stroke:red; stroke-width:1px" />
<text x="30" y="30" style="font-size:10">Move this area.</text>
</g>

3.  Get the entries from the Form field(s) on the HTML page.
   var xPixels = document.formName.fieldNameX.value;
   var yPixels = document.formName.fieldNameY.value;

4.  Apply a transform (for example) to the element named "AreaToMove"
   svgobj.setAttribute('transform','translate(' + xPixels + " " 
+ yPixels +')');


------------------------------------------------------------
Examples of changing attributes using JavaScript:   
var svgdoc = document.embeds[0].getSVGDocument();
var svgobj = svgdoc.getElementById("AreaToChange");
   svgobj.setAttribute('transform','scale(' + scaleAmount +')');
   svgobj.setAttribute('transform','translate(' + xPixels  +" "+ 
yPixels +')');
   etc.

Examples of changing properties from external JavaScript
var svgdoc = document.embeds[0].getSVGDocument();
var svgobj = svgdoc.getElementById("AreaToChange");
var svgstyle = svgobj.getStyle();
   svgstyle.setProperty ('fill-opacity', 1);
   svgstyle.setProperty('fill','#33FF66');
   svgstyle.setProperty('stroke', '#0000FF');
   svgstyle.setProperty('stroke-width', '5');      
   etc.

Examples of changing text and its properties from external Javascript
var svgdoc = document.embeds[0].getSVGDocument();
var svgobj = svgdoc.getElementById("AreaToChange");
var text_element = svgdoc.getElementById('TextElement');
var first_child = text_element.getFirstChild();
first_child.setData ("The New Text");

var svgstyle = text_element.getStyle();
   svgstyle.setProperty('fill', '#33FF66');
   svgstyle.setProperty(font-family, 'Verdana');
   svgstyle.setProperty(font-size, '24');
   etc.
