在raphael.js中的数组元素上拖动（）

Question

I have a lot of Raphael elements which I push into an array:

var start = function () {
                this.ox = this.attr("cx");
                this.oy = this.attr("cy");
            },
            move = function (dx, dy) {
                this.attr({cx: this.ox + dx, cy: this.oy + dy});
            }    

for(var i = 0; i < 149; i++) {
    cubes = paper.rect(Math.floor(Math.random()*2000), Math.floor(Math.random()*2000), 0, 0);
    cubes.animate({ width: 25, height: 25 }, 500, "bounce");
    cubesmixed.push(cubes);
    cubesmixed[i].drag(move, start);
}

but unfortunatly I can't drag them. The most weird thing is, that start and move fire as they should. But why do they don't move.

Thanks in advance!

First of all attribute cx, cy are used in circles and elipsis so updating them will not move your rectangle which uses x and y attributes. If what you want to achieve is to move them simultanously (that was my first impression when I started to read your question - but I am not sure about that anymore :)), then please refer to this question.
