javascript – Pass attribute, not value as parameter

I would like to make this happen in JavaScript:

function changeAttributeValue(theAttribute, numberOfPixels)
{
    theAttribute = numberOfPixels + \"px\";
}

changeAttributeValue(myImage.style.left, 50);
changeAttributeValue(myImage.style.top, 80);
changeAttributeValue(myCanvas.width, 600);

The first two calls should move an image and the third should adjust the width of a canvas.

Like this however, just the value of the passed variables were passed, so nothing happens.

Does anybody know how to solve this problem?
