Creating an SVG in Javascript, trivial example
I’m no JS coder, but for my reference below is a simple example showing how to create an SVG image in Javascript. The code below also shows how the SVG element itself might be created in JS.
UPDATE: If you’re looking at creating SVGs in Javascript, I recommend checking out FabricJS, I found it much easier to get what I wanted working.
<html>
<body>
<script language="javascript">
var svgNS = "http://www.w3.org/2000/svg";
function do_draw() {
// The following commands can be used to create an SVG programatically
// var mySVG = document.createElementNS("http://www.w3.org/2000/svg", "svg");
// mySVG.setAttribute("height",300);
// mySVG.setAttribute("width" ,300);
// document.body.appendChild(mySVG);
var mySVG = document.getElementById('mySVG')
var circles = document.createElementNS("http://www.w3.org/2000/svg", "circle");
circles.setAttribute("cx",20);
circles.setAttribute("cy",20);
circles.setAttribute("r",20);
mySVG.appendChild(circles);
}
</script>
<svg id="mySVG" style="width:300px; height:300px" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink"/>
<input type="button" id="drawBtn" value="draw" onclick="do_draw()"></input><br><br>
<div id='main'></div>
</body>
</html>
