javascript - JqueryUI Animation from one button to another -


i'm trying create function use later, animate button1 twords button2, make button1 same size button2 , bring button1 original position , size.

i managed return button1 original position, can't figure out size part, keeps making button smaller , smaller, please see jfiddle below, think it's not counting padding, , i'm not sure how.

function movefromto(fromid, toid, relative) {    var fromshape = $("#" + fromid);    var toshape = $("#" + toid);    var fromposition;    var toposition;     if (relative === true) {      fromposition = fromshape.offset();      toposition = toshape.offset();    } else {      fromposition = fromshape.position();      toposition = toshape.position();    }     console.log(fromshape);    console.log("width " + fromshape.width() + "px" + ", height " + fromshape.height() + "px");    console.log(toshape);    console.log("width " + toshape.width() + "px" + ", height " + toshape.height() + "px");     var initproperties = {      top: 0,      left: 0,      width: fromshape.width() + "px",      height: fromshape.height() + "px"    };    var properties = {      top: (toposition.top - fromposition.top) + "px",      left: (toposition.left - fromposition.left) + "px",      width: toshape.width() * 1.2 + "px",      height: toshape.height() * 1.2 + "px"    };     console.log(toshape.width() * 1.2 + "px");    console.log(toshape.height() * 1.2 + "px");     fromshape      .animate(properties, 1000, function() {        toshape.toggle("explode", {          pieces: 100        }, 500);      })      .animate(initproperties, 200, function() {        toshape.toggle("explode", {          pieces: 100        }, 100);      });   };
