Get element -moz-transform:rotate value in jQuery

I have CSS style for a layer:

.element {
    -webkit-transform: rotate(7.5deg);    
     -moz-transform: rotate(7.5deg);    
      -ms-transform: rotate(7.5deg);    
       -o-transform: rotate(7.5deg);   
          transform: rotate(7.5deg);
}

Is there a way to get curent rotation value through jQuery?

I tried this

$('.element').css("-moz-transform")

The result is matrix(0.991445, 0.130526, -0.130526, 0.991445, 0px, 0px) which doesn't tell me a lot. What I'm looking to get is 7.5.


Here's my solution using jQuery.

This returns a numerical value corresponding to the rotation applied to any HTML element.

function getRotationDegrees(obj) {
    var matrix = obj.css("-webkit-transform") ||
    obj.css("-moz-transform")    ||
    obj.css("-ms-transform")     ||
    obj.css("-o-transform")      ||
    obj.css("transform");
    if(matrix !== 'none') {
        var values = matrix.split('(')[1].split(')')[0].split(',');
        var a = values[0];
        var b = values[1];
        var angle = Math.round(Math.atan2(b, a) * (180/Math.PI));
    } else { var angle = 0; }
    return (angle < 0) ? angle + 360 : angle;
}

angle1 = getRotationDegrees($('#myDiv'));
angle2 = getRotationDegrees($('.mySpan a:last-child'));

etc...


I've found a bug/features in the Twist's code: the function return negative angles.

So I've add a simple line of code before returning the angle:

if(angle < 0) angle +=360;

Than the results will be:

function getRotationDegrees(obj) {
    var matrix = obj.css("-webkit-transform") ||
    obj.css("-moz-transform")    ||
    obj.css("-ms-transform")     ||
    obj.css("-o-transform")      ||
    obj.css("transform");
    if(matrix !== 'none') {
        var values = matrix.split('(')[1].split(')')[0].split(',');
        var a = values[0];
        var b = values[1];
        var angle = Math.round(Math.atan2(b, a) * (180/Math.PI));
    } else { var angle = 0; }

    if(angle < 0) angle +=360;
    return angle;
}
