jQuery animate css border-radius property (webkit, mozilla)

Is there a way in jQuery to animate the css3 border-radius property available in Webkit and Mozilla browsers?

I haven't found a plugin that will do it.

-webkit-border-radius

-moz-border-radius

I originally expected that something like...

$("selector")
  .css({borderRadius: 10});
  .animate({borderRadius: 30}, 900);

...would work. But, I was wrong: Webkit allows you to set the value for all four corners via borderRadius, but won't let you read it back - so with the code above, the animation will always start at 0 instead of 10. IE has the same problem. Firefox will let you read it back, so everything works as expected there.

Well... border-radius has sort of a history of implementation differences.

Fortunately, there's a work-around: just specify each corner radius individually:

$("selector")
  .css({
    borderTopLeftRadius: 10, 
    borderTopRightRadius: 10, 
    borderBottomLeftRadius: 10, 
    borderBottomRightRadius: 10 })
  .animate({
    borderTopLeftRadius: 30, 
    borderTopRightRadius: 30, 
    borderBottomLeftRadius: 30, 
    borderBottomRightRadius: 30}, 900);

Note that if you wish to maintain compatibility with older browsers, you can go all-out and use the old browser-prefixed names:

$("selector")
  .css({
    borderTopLeftRadius: 10, 
    borderTopRightRadius: 10, 
    borderBottomLeftRadius: 10, 
    borderBottomRightRadius: 10,
    WebkitBorderTopLeftRadius: 10, 
    WebkitBorderTopRightRadius: 10, 
    WebkitBorderBottomLeftRadius: 10, 
    WebkitBorderBottomRightRadius: 10, 
    MozBorderRadius: 10 
  })
  .animate({
    borderTopLeftRadius: 30, 
    borderTopRightRadius: 30, 
    borderBottomLeftRadius: 30, 
    borderBottomRightRadius: 30,
    WebkitBorderTopLeftRadius: 30, 
    WebkitBorderTopRightRadius: 30, 
    WebkitBorderBottomLeftRadius: 30, 
    WebkitBorderBottomRightRadius: 30, 
    MozBorderRadius: 30 
  }, 900);

This starts to get pretty crazy though; I would avoid it if possible.

Use cssHooks.

Good luck!

Juste an advice, we can use a function to detect browser's CSS prefix Here a sample code.. http://jsfiddle.net/molokoloco/f6Z3D/
