How to make Chrome redraw SVG dynamically added content?
- by Adrian
I've dynamacally added the circle elements to the svg displayed in a iFrame. Chrome isnt showing the new elements, not tried FF yet. Is there somekind of redraw/refresh I need to call? The first circle is actually in the svg document, the rest come from script.
<iframe id="svgFrame" src="xmlfile1.svg" width="300" height="300">
<svg xmlns="http://www.w3.org/2000/svg" id="SVG1" width="200" height="200">
<circle cx="20" cy="20" r="5"/>
<circle cx="165" cy="80" r="32"/>
<circle cx="15" cy="38" r="32"/>
<circle cx="140" cy="39" r="30"/>
<circle cx="178" cy="32" r="22"/>
...etc
<circle cx="166" cy="130" r="16"/>
</svg>
</iframe>
The javascript which creates the elements:
function RandomNumber(min, max) {
var r;
r = Math.floor(Math.random() * (max - min + 1)) + min;
return r;
}
var svg = document.getElementById("svgFrame").contentDocument;
for (var i = 0; i < 99; i++) {
var n = svg.createElement("circle");
n.setAttribute("cx" , RandomNumber( 0 , 200) );
n.setAttribute("cy" , RandomNumber(0, 200) );
n.setAttribute("r" , RandomNumber(5, 35) );
svg.documentElement.appendChild(n);
}
