css transition animation doesn't work on svg path's "d' attribute change

Question

jsFiddle

I'm trying to apply css transition to svg various elements. transition: all 2s works great for circle however it doesn't work for path.

How is there something more specific then "all"?

EDITED:

Below link has more info animating svg line or path... and it seems that it is not possible with css transition yet...

Can you use CSS transitions on SVG attributes? Like y2 on a line?

Answer 1

Transitions can only be applied to presentation Attributes, and a few other attributes such as x, y, cx,cy ... a list of supported attributes can be found here http://dev.w3.org/SVG/proposals/css-animation/animation-proposal.html Unfortunately d isn't one of them...

as this is still not supported reliably across browsers, you can use SMIL animations to achieve the same result.

var type = true;

setInterval(function() {
    $("#path").attr('from', type ? "M 0 0 L 50 100" : "M 0 0 L 100 50");
    $("#path").attr('to', type ? "M 0 0 L 100 50" : "M 0 0 L 50 100");
    $("#path")[0].beginElement()
    $("#circle").attr('from', type ? "40" : "10");
    $("#circle").attr('to', type ? "10" : "40");
    $("#circle")[0].beginElement()
    type = !type;
}, 1000);
