jQuery attr() fails to set attribute

I am trying to rotate an image via svg's transform. This is the code I have:

<svg width="100" height="100"> 
   <image id="trns" transform="rotate(90,50,50)" width="100" height="100" xlink:href="logo.png"/> 
</svg>

This successfully rotates logo.png by 90 degrees when the page loads. Also, when I change 90 to a different number in firbug's HTML tab the rotation changes accordingly. But when I try to change the value with jQuery,开发者_如何学运维 nothing happens:

$('#trns').attr('transform', 'rotate(60, 50,50)');

What does firebug do that my attr line does not?

Working fine here (with jQuery 1.6.2): http://jsfiddle.net/niklasvh/k3Grd/

Make sure to call it once the DOM is ready:

$(function(){
 $('#trns').attr('transform', 'rotate(60,50,50)');
});

Very strange indeed, this seems to work

$('#trns')[0].setAttribute('transform','rotate(20,50,50)')

Also, if u look at $('#trns').attr('transform'), you are getting an object.. Not enough time to look into that now.

If you're using jquery >= 1.6 try using prop instead of attr.
Hope this helps. Cheers

.attr() works in 3.1.1 like this

.attr({ style: "prop : val; prop : val; prop : val" })

this might be a way around version problems.
